O gerenciamento do Earned Value vem obtendo aceitação crescente nas empresas e entre profissionais tais como gerentes de projetos e funcionais, devido à sua efetividade no controle dos resultados do projeto. Earned Value é definido como uma ferramenta de controle que permite avaliar simultaneamente de maneira quantitativa como se encontram os custos e prazos em uma data de controle, permitindo também prever a data de término e o valor gasto (VARGAS, 2005). Este artigo avalia a aplicabilidade do earned value como ferramenta de controle de projetos aeronáuticos na EMBRAER. Contribui também para a aplicação do earned value no controle de projetos complexos. Utilizam-se como técnicas de coleta de dados: entrevistas, observações e análise documental. Conclui-se que o earned value é utilizado apenas nos projetos da área de aviação de defesa, por ser uma exigência contratual. O uso do earned value nas áreas de programas executivos e comerciais restringe-se às fases de definição conjunta, projeto detalhado e certificação, pois o escopo do projeto é bem definido, o cronograma é detalhado e os custos são previstos e obtidos com maior acuidade. Nas demais fases de desenvolvimento do produto, o uso do earned value é restrito, devido principalmente às constantes alterações de escopo do produto e do projeto.

Este informe trata el diseño, desarrollo y construcción de un aerodeslizador de pequeño tamaño, equipado con control remoto que permite al usuario actuar sobre la velocidad y dirección del mismo. Este proyecto podrá ser utilizado en un futuro como base para el desarrollo de aplicaciones más complejas. Un aerodeslizador es un medio de transporte cuyo chasis se eleva sobre el suelo por medio de un motor impulsor que hincha una falda colocada en la parte inferior del mismo. Además, uno o más motores se colocan en la parte trasera del vehículo para propulsarlo. El hecho de que el aerodeslizador no este en contacto directo con la tierra, hace que pueda moverse tanto por tierra como sobre el agua o hielo y que sea capaz de superar pequeños obstáculos. Por otra parte, este hecho se convierte a su vez en un problema debido a que su fuerza de rozamiento al desplazarse es muy pequeña, lo que provoca que sea muy difícil de frenar, y tienda a girar por sí mismo debido a la inercia del movimiento y a las fuerzas provocadas por las corrientes de aire debajo del chasis. Sin embargo, para este proyecto no se ha colocado una falda debajo del mismo, debido a que su diseño es bastante complicado, por lo tanto la fricción con el suelo es menor, aumentando los problemas detallados con anterioridad. El proyecto consta de dos partes, mando a distancia y aerodeslizador, que se conectan a través de antenas de radiofrecuencia (RF). El diseño y desarrollo de cada una ha sido realizado de manera separada exceptuando la parte de las comunicaciones entre ambas. El mando a distancia se divide en tres partes. La primera está compuesta por la interfaz de usuario y el circuito que genera las señales analógicas correspondientes a sus indicaciones. La interfaz de usuario la conforman tres potenciómetros: uno rotatorio y dos deslizantes. El rotatorio se utiliza para controlar la dirección de giro del aerodeslizador, mientras que cada uno de los deslizantes se emplea para controlar la fuerza del motor impulsor y del propulsor respectivamente. En los tres casos los potenciómetros se colocan en el circuito de manera que actúan como divisores de tensión controlables. La segunda parte se compone de un microcontrolador de la familia PSoC. Esta familia de microcontroladores se caracteriza por tener una gran adaptabilidad a la aplicación en la que se quieran utilizar debido a la posibilidad de elección de los periféricos, tanto analógicos como digitales, que forman parte del microcontrolador. Para el mando a distancia se configura con tres conversores A/D que se encargan de transformar las señales procedentes de los potenciómetros, tres amplificadores programables para trabajar con toda la escala de los conversores, un LCD que se utiliza para depurar el código en C con el que se programa y un módulo SPI que es la interfaz que conecta el microcontrolador con la antena. Además, se utilizan cuatro pines externos para elegir el canal de transmisión de la antena. La tercera parte es el módulo transceptor de radio frecuencia (RF) QFM-TRX1-24G, que en el mando a distancia funciona como transmisor. Éste utiliza codificación Manchester para asegurar bajas tasas de error. Como alimentación para los circuitos del mando a distancia se utilizan cuatro pilas AA de 1,5 voltios en serie. En el aerodeslizador se pueden distinguir cinco partes. La primera es el módulo de comunicaciones, que utiliza el mismo transceptor que en el mando a distancia, pero esta vez funciona como receptor y por lo tanto servirá como entrada de datos al sistema haciendo llegar las instrucciones del usuario. Este módulo se comunica con el siguiente, un microcontrolador de la familia PSoC, a través de una interfaz SPI. En este caso el microcontrolador se configura con: un modulo SPI, un LCD utilizado para depurar el código y tres módulos PWM (2 de 8 bits y uno de 16 bits) para controlar los motores y el servo del aerodeslizador. Además, se utilizan cuatro pines externos para seleccionar el canal de recepción de datos. La tercera y cuarta parte se pueden considerar conjuntamente. Ambas están compuestas por el mismo circuito electrónico basado en transistores MOSFET. A la puerta de cada uno de los transistores llega una señal PWM de 100 kilohercios que proviene del microcontrolador, que se encarga de controlar el modo de funcionamiento de los transistores, que llevan acoplado un disipador de calor para evitar que se quemen. A su vez, los transistores hacen funcionar al dos ventiladores, que actúan como motores, el impulsor y el propulsor del aerodeslizador. La quinta y última parte es un servo estándar para modelismo. El servo está controlado por una señal PWM, en la que la longitud del pulso positivo establece la posición de la cabeza del servo, girando en uno u otra dirección según las instrucciones enviadas desde el mando a distancia por el usuario. Para el aerodeslizador se han utilizado dos fuentes de alimentación diferentes: una compuesta por 4 pilas AA de 1,5 voltios en serie que alimentarán al microcontrolador y al servo, y 4 baterías de litio recargables de 3,2 voltios en serie que alimentan el circuito de los motores. La última parte del proyecto es el montaje y ensamblaje final de los dispositivos. Para el chasis del aerodeslizador se ha utilizado una cubierta rectangular de poli-estireno expandido, habitualmente encontrado en el embalaje de productos frágiles. Este material es bastante ligero y con una alta resistencia a los golpes, por lo que es ideal para el propósito del proyecto. En el chasis se han realizado dos agujeros: uno circular situado en el centro del mismo en el se introduce y se ajusta con pegamento el motor impulsor, y un agujero con la forma del servo, situado en uno del los laterales estrechos del rectángulo, en el que se acopla el mismo. El motor propulsor está adherido al cabezal giratorio del servo de manera que rota a la vez que él, haciendo girar al aerodeslizador. El resto de circuitos electrónicos y las baterías se fijan al chasis mediante cinta adhesiva y pegamento procurando en todo momento repartir el peso de manera homogénea por todo el chasis para aumentar la estabilidad del aerodeslizador. SUMMARY: In this final year project a remote controlled hovercraft was designed using mainly technology that is well known by students in the embedded systems programme. This platform could be used to develop further and more complex projects. The system was developed dividing the work into two parts: remote control and hovercraft. The hardware was of the hovercraft and the remote control was designed separately; however, the software was designed at the same time since it was needed to develop the communication system. The result of the project was a remote control hovercraft which has a user friendly interface. The system was designed based on microprocessor technologies and uses common remote control technologies. The system has been designed with technology commonly used by the students in Metropolia University so that it can be readily understood in order to develop other projects based on this platform.

Para hacerse cargo del legado de las Plantas de Gas Manufacturado (MGP) en el Estado de Nueva York, la División de Remediación Medioambiental del Departamento de Conservación Medioambiental, creo las Investigaciones de las áreas afectadas y el Programa de Remediación Medioambiental. Con el paso de los años, la conciencia y entendimiento de la importancia y complejidad de estos proyectos fue creciendo, ya que las investigaciones realizadas daban fe del tamaño y extensión de la contaminación asociada a las plantas de gas manufacturado, propiedad ahora de las diversas compañías de gas que operan a lo largo y ancho del Estado de Nueva York. Tras varios años dentro del Programa de Remediación Medioambiental, muchas de estas compañías han intentado manejar estos vastos y complejos proyectos como han podido, dejándose llevar un poco, subestimando y pasando por alto muchos detalles, ya que al fin y al cabo son proyecto regulados por el estado y que, por tanto, son financiados enteramente por este. Esto ha ido causando en los últimos años grandes problemas a algunas Compañías que a la hora de reportar estos proyectos se han encontrado con una falta total de control y grandes lagunas que resolver. Una técnica para resolver estos problemas es hacer uso de grandes técnicas de gestión empresarial como es el Project Management. En este proyecto se exponen y desarrollan las técnicas que han de utilizarse para integrar la Gestión de Proyectos con el fin de poder gestionar y coordinar las competentes demandas de alcance, tiempo, costes, calidad, recursos, y riesgos con el fin de alcanzar los requerimientos y objetivos del proyecto y de la Compañía. ABSTRACT To address the Manufactured Gas Plant (MGP) legacy in New York State, the Department of Environmental Conservation’s Division of Environmental Remediation has established the MGP Site Investigation and Remediation Programs. With the passage of time the Department’s understanding of the complexity of these sites grew, as investigations identified the extend of the contamination problem associated with many MGPs, property of the Operating Companies in the State. Through many years under the Remediation Programs, some Operating Companies have tried to manage these large and complex projects as they could, underestimating and overlooking them, as they were, in fact, regulated and financed by the Department. This has cause a lot of controlling issues and gaps to solve to the companies. Now the companies are trying to solve this kind of problems using the more innovative management techniques, as Project Management. This project expose and explains how to integrate the project management processes into the MGP Projects under the Remediation Program, to manage and balance the competing demands of scope, time ,cost, quality, resources, and risk to meet the project and company’s requirements and objectives.

El sector de la edificación es uno de los principales sectores económicos en España y, además, es un componente básico de la actividad económica y social, debido a su importante papel como generador de empleo, proveedor de bienes e incentivador del crecimiento. Curiosamente, es uno de los sectores con menos regulación y organización y que, además, está formado mayoritariamente por empresas de pequeña y mediana dimensión (pymes) que, por su menor capacidad, a menudo, se quedan detrás de las grandes empresas en términos de adopción de soluciones innovadoras. La complejidad en la gestión de toda la información relacionada con un proyecto de edificación ha puesto de manifiesto claras ineficiencias que se traducen en un gasto innecesario bastante representativo. La información y los conocimientos aprendidos rara vez son transmitidos de una fase a otra dentro del proyecto de edificación y, mucho menos, reutilizados en otros proyectos similares. De este modo, no sólo se produce un gasto innecesario, sino que incluso podemos encontrar información contradictoria y obsoleta y, por tanto, inútil para la toma de decisiones. A lo largo de los años, esta situación ha sido motivada por la propia configuración del sector, poniendo de manifiesto la necesidad de una solución que pudiera solventar este reto de gestión interorganizacional. Así, la cooperación interorganizacional se ha convertido en un factor clave para mejorar la competitividad de las organizaciones, típicamente pymes, que componen el sector de la edificación. La información es la piedra angular de cualquier proceso de negocio. Durante la última década, una amplia gama de industrias han experimentado importantes mejoras de productividad con la aplicación eficiente de las TIC, asociadas, principalmente, a incrementos en la velocidad de proceso de información y una mayor coherencia en la generación de datos, accesibilidad e intercambio de información. La aplicación eficaz de las TIC en el sector de la edificación requiere una combinación de aspectos estratégicos y tácticos, puesto que no sólo se trata de utilizar soluciones puntuales importadas de otros sectores para su aplicación en diferentes áreas, sino que se buscaría que la información multi-agente estuviera integrada y sea coherente para los proyectos de edificación. El sector de la construcción ha experimentado un descenso significativo en los últimos años en España y en Europa como resultado de la crisis financiera que comenzó en 2007. Esta disminución está acompañada de una baja penetración de las TIC en la interorganizacionales orientadas a los procesos de negocio. El descenso del mercado ha provocado una desaceleración en el sector de la construcción, donde sólo las pymes flexibles han sido capaces de mantener el ritmo a pesar de la especialización y la innovación en los servicios adaptados a las nuevas demandas del mercado. La industria de la edificación está muy fragmentada en comparación con otras industrias manufactureras. El alto grado de esta fragmentación está íntimamente relacionado con un impacto significativo en la productividad y el rendimiento. Muchos estudios de investigación han desarrollado y propuesto una serie de modelos de procesos integrados. Por desgracia, en la actualidad todavía no se está en condiciones para la formalización de cómo debe ser la comunicación y el intercambio de información durante el proceso de construcción. El paso del proceso secuencial tradicional a los procesos de interdependencia recíproca sin lugar a duda son una gran demanda asociada a la comunicación y el flujo de información en un proyecto de edificación. Recientemente se está poniendo mucho énfasis en los servicios para el hogar como un primer paso hacia esta mejora en innovación ya que la industria de los servicios digitales interactivos tiene un alto potencial para generar innovación y la ventaja estratégica para las empresas existentes. La multiplicidad de servicios para el hogar digital (HD) y los proveedores de servicios demandan, cada vez más, la aparición de una plataforma capaz de coordinar a todos los agentes del sector con el usuario final. En consecuencia, las estructuras organizacionales tienden a descentralizarse en busca de esa coordinación y, como respuesta a esta demanda, se plantea, también en este ámbito, el concepto de cooperación interorganizacional. Por lo tanto, ambos procesos de negocio -el asociado a la construcción y el asociado a la provisión de servicios del hogar digital, también considerado como la propia gestión de ese hogar digital o edificio, inteligente o no- deben de ser vistos en su conjunto mediante una plataforma tecnológica que les dé soporte y que pueda garantizar la agregación e integración de los diversos procesos, relacionados con la construcción y gestión, que se suceden durante el ciclo de vida de un edificio. Sobre esta idea y atendiendo a la evolución permanente de los sistemas de información en un entorno de interrelación y cooperación daría lugar a una aplicación del concepto de sistema de información interorganizacional (SIIO). El SIIO proporciona a las organizaciones la capacidad para mejorar los vínculos entre los socios comerciales a lo largo de la cadena de suministro, por lo que su importancia ha sido reconocida por organizaciones de diversos sectores. Sin embargo, la adopción de un SIIO en diferentes ámbitos ha demostrado ser complicada y con una alta dependencia de las características particulares de cada sector, siendo, en este momento, una línea de investigación abierta. Para contribuir a esta línea de investigación, este trabajo pretende recoger, partiendo de una revisión de la literatura relacionada, un enfoque en un modelo de adopción de un SIIO para el objeto concreto de esta investigación. El diseño de un SIIO está basado principalmente, en la identificación de las necesidades de información de cada uno de sus agentes participantes, de ahí la importancia en concretar un modelo de SIIO en el ámbito de este trabajo. Esta tesis doctoral presenta el modelo de plataforma virtual de la asociación entre diferentes agentes del sector de la edificación, el marco de las relaciones, los flujos de información correspondientes a diferentes procesos y la metodología que subyace tras el propio modelo, todo ello, con el objeto de contribuir a un modelo unificado que dé soporte tanto a los procesos relacionados con la construcción como con la gestión de servicios en el hogar digital y permitiendo cubrir los requisitos importantes que caracterizan este tipo de proyectos: flexibilidad, escalabilidad y robustez. El SIIO se ha convertido en una fuente de innovación y una herramienta estratégica que permite a las pymes obtener ventajas competitivas. Debido a la complejidad inherente de la adopción de un SIIO, esta investigación extiende el modelo teórico de adopción de un SIIO de Kurnia y Johnston (2000) con un modelo empírico para la caracterización de un SIIO. El modelo resultante tiene como objetivo fomentar la innovación de servicios en el sector mediante la identificación de los factores que influyen en la adopción de un SIIO por las pymes en el sector de la edificación como fuente de ventaja competitiva y de colaboración. Por tanto, esta tesis doctoral, proyectada sobre una investigación empírica, proporciona un enfoque para caracterizar un modelo de SIIO que permita dar soporte a la gestión integrada de los procesos de construcción y gestión de servicios para el hogar digital. La validez del modelo de SIIO propuesto, como fuente y soporte de ventajas competitivas, está íntimamente relacionada con la necesidad de intercambio de información rápido y fiable que demandan los agentes del sector para mejorar la gestión de su interrelación y cooperación con el fin de abordar proyectos más complejos en el sector de la edificación, relacionados con la implantación del hogar digital, y contribuyendo, así a favorecer el desarrollo de la sociedad de la información en el segmento residencial. ABSTRACT The building industry is the largest industry in the world. Land purchase, building design, construction, furnishing, building equipment, operations maintenance and the disposition of real estate have an unquestionable prominence not only at economic but also at social level. In Spain, the building sector is one of the main drivers of economy and also a basic component of economic activity and its role in generating employment, supply of goods or incentive for growth is crucial in the evolution of the economy. Surprisingly, it is one of the sectors with less regulation and organization. Another consistent problem is that, in this sector, the majority of companies are small and medium (SMEs), and often behind large firms in terms of their adoption of innovative solutions. The complexity of managing all information related to this industry has lead to a waste of money and time. The information and knowledge gathered is frequently stored in multiple locations, involving the work of thousands of people, and is rarely transferred on to the next phase. This approach is inconsistent and makes that incorrect information is used for decisions. This situation needs a viable solution for interorganizational information management. So, interorganizational co-operation has become a key factor for organization competitiveness within the building sector. Information is the cornerstone of any business process. Therefore, information and communication technologies (ICT) offer a means to change the way business is conducted. During the last decade, significant productivity improvements were experienced by a wide range of industries with ICT implementation. ICT has provided great advantages in speed of operation, consistency of data generation, accessibility and exchange of information. The wasted money resulting from reentering information, errors and omissions caused through poor decisions and actions, and the delays caused while waiting for information, represent a significant percentage of the global benefits. The effective application of ICT in building construction sector requires a combination of strategic and tactical developments. The building sector has experienced a significant decline in recent years in Spain and in Europe as a result of the financial crisis that began in 2007. This drop goes hand in hand with a low penetration of ICT in inter-organizational-oriented business processes. The market decrease has caused a slowdown in the building sector, where only flexible SMEs have been able to keep the pace though specialization and innovation in services adapted to new market demands. The building industry is highly fragmented compared with other manufacturing industries. This fragmentation has a significant negative impact on productivity and performance. Many research studies have developed and proposed a number of integrated process models. Unfortunately, these studies do not suggest how communication and information exchange within the construction process can be achieved, without duplication or lost in quality. A change from the traditional sequential process to reciprocal interdependency processes would increase the demand on communication and information flow over the edification project. Focusing on home services, the digital interactive service industry has the potential to generate innovation and strategic advantage for existing business. Multiplicity of broadband home services (BHS) and suppliers suggest the need for a figure able to coordinate all the agents in sector with the final user. Consequently, organizational structures tend to be decentralized. Responding to this fact, the concept of interorganizational co-operation also is raising in the residential market. Therefore, both of these business processes, building and home service supply, must be complemented with a technological platform that supports these processes and guarantees the aggregation and integration of the several services over building lifecycle. In this context of a technological platform and the permanent evolution of information systems is where the relevance of the concept of inter-organizational information system (IOIS) emerges. IOIS improves linkages between trading partners along the supply chain. However, IOIS adoption has proved to be difficult and not fully accomplished yet. This research reviews the literature in order to focus a model of IOIS adoption. This PhD Thesis presents a model of virtual association, a framework of the relationships, an identification of the information requirements and the corresponding information flows, using the multi-agent system approach. IOIS has become a source of innovation and a strategic tool for SMEs to obtain competitive advantage. Because of the inherent complexity of IOIS adoption, this research extends Kurnia and Johnston’s (2000) theoretical model of IOIS adoption with an empirical model of IOIS characterization. The resultant model aims to foster further service innovation in the sector by identifying the factors influencing IOIS adoption by the SMEs in the building sector as a source of competitive and collaborative advantage. Therefore, this PhD Thesis characterizes an IOIS model to support integrated management of building processes and home services. IOIS validity, as source and holder of competitive advantages, is related to the need for reliable information interchanges to improve interrelationship management. The final goal is to favor tracking of more complex projects in building sector and to contribute to consolidation of the information society through the provision of broadband home services and home automation.

The School of Industrial Engineering at Universidad Politécnica de Madrid (ETSII-UPM) has been promoting student-centred teaching-learning activities, according to the aims of the Bologna Declaration, well before the official establishment of the European Area of Higher Education. Such student-centred teaching-learning experiences led us to the conviction that project based learning is rewarding, both for students and academics, and should be additionally promoted in our new engineering programmes, adapted to the Grade-Master structure. The level of commitment of our teachers with these activities is noteworthy, as the teaching innovation experiences carried out in the last ten years have led to the foundation of 17 Teaching Innovation Groups at ETSII-UPM, hence leading the ranking of teaching innovation among all UPM centres. Among interesting CDIO activities our students have taken part in especially complex projects, including the Formula Student, linked to the complete development of a competition car, and the Cybertech competition, aimed at the design, construction and operation of robots for different purposes. Additional project-based learning teamwork activities have been linked to toy design, to the development of medical devices, to the implementation of virtual laboratories, to the design of complete industrial installations and factories, among other activities detailed in present study. The implementation of Bologna process will culminate at ETSII-UPM with the beginning of the Master’s Degree in Industrial Engineering, in academic year 2014-15. The program has been successfully approved by the Spanish Agency for Accreditation (ANECA), with the inclusion of a set of subjects based upon the CDIO methodology denominated generally “INGENIA”, linked to the Spanish “ingeniar” (to provide ingenious solutions), also related etymologically in Spanish with “ingeniero”, engineer. INGENIA students will live through the complete development process of a complex product or system and there will be different kind of projects covering most of the engineering majors at ETSII-UPM.

The auditory system of monkeys includes a large number of interconnected subcortical nuclei and cortical areas. At subcortical levels, the structural components of the auditory system of monkeys resemble those of nonprimates, but the organization at cortical levels is different. In monkeys, the ventral nucleus of the medial geniculate complex projects in parallel to a core of three primary-like auditory areas, AI, R, and RT, constituting the first stage of cortical processing. These areas interconnect and project to the homotopic and other locations in the opposite cerebral hemisphere and to a surrounding array of eight proposed belt areas as a second stage of cortical processing. The belt areas in turn project in overlapping patterns to a lateral parabelt region with at least rostral and caudal subdivisions as a third stage of cortical processing. The divisions of the parabelt distribute to adjoining auditory and multimodal regions of the temporal lobe and to four functionally distinct regions of the frontal lobe. Histochemically, chimpanzees and humans have an auditory core that closely resembles that of monkeys. The challenge for future researchers is to understand how this complex system in monkeys analyzes and utilizes auditory information.

Much research has been devoted over the years to investigating and advancing the techniques and tools used by analysts when they model. As opposed to what academics, software providers and their resellers promote as should be happening, the aim of this research was to determine whether practitioners still embraced conceptual modeling seriously. In addition, what are the most popular techniques and tools used for conceptual modeling? What are the major purposes for which conceptual modeling is used? The study found that the top six most frequently used modeling techniques and methods were ER diagramming, data flow diagramming, systems flowcharting, workflow modeling, UML, and structured charts. Modeling technique use was found to decrease significantly from smaller to medium-sized organizations, but then to increase significantly in larger organizations (proxying for large, complex projects). Technique use was also found to significantly follow an inverted U-shaped curve, contrary to some prior explanations. Additionally, an important contribution of this study was the identification of the factors that uniquely influence the decision of analysts to continue to use modeling, viz., communication (using diagrams) to/from stakeholders, internal knowledge (lack of) of techniques, user expectations management, understanding models' integration into the business, and tool/software deficiencies. The highest ranked purposes for which modeling was undertaken were database design and management, business process documentation, business process improvement, and software development.

Purpose: The purpose of this paper is to describe how the application of systems thinking to designing, managing and improving business processes has resulted in a new and unique holonic-based process modeling methodology know as process orientated holonic modeling. Design/methodology/approach: The paper describes key systems thinking axioms that are built upon in an overview of the methodology; the techniques are described using an example taken from a large organization designing and manufacturing capital goods equipment operating within a complex and dynamic environment. These were produced in an 18 month project, using an action research approach, to improve quality and process efficiency. Findings: The findings of this research show that this new methodology can support process depiction and improvement in industrial sectors which are characterized by environments of high variety and low volume (e.g. projects; such as the design and manufacture of a radar system or a hybrid production process) which do not provide repetitive learning opportunities. In such circumstances, the methodology has not only been able to deliver holonic-based process diagrams but also been able to transfer strategic vision from top management to middle and operational levels without being reductionistic. Originality/value: This paper will be of interest to organizational analysts looking at large complex projects whom require a methodology that does not confine them to thinking reductionistically in "task-breakdown" based approaches. The novel ideas in this paper have great impact on the way analysts should perceive organizational processes. Future research is applying the methodology in similar environments in other industries. © Emerald Group Publishing Limited.

This project supported the planning and conduct of a two-day Iowa Department of Transportation–hosted peer exchange for state agencies that have implemented some or all of the suggested strategies outlined in the Second Strategic Highway Research Program–sponsored project R10, Project Management Strategies for Complex Projects. Presentations were made by participating states, and several opportunities were provided for directed discussion. General themes emerging from the presentations and discussions were identified as follows: To implement improvements in project management processes, agency leadership needs to decide that a new approach to project management is worth pursuing and then dedicate resources to developing a project management plan. The change to formalized project management and five-dimensional project management (5DPM) requires a culture shift in agencies from segmented “silo” processes to collaborative, cooperative processes that make communication and collaboration high priorities. Agencies need trained project managers who are empowered to execute the project management plan, as well as properly trained functional staff. Project management can be centralized or decentralized with equal effect. After an agency’s project management plan and structure are developed, software tools and other resources should be implemented to support the plan and structure. All projects will benefit from enhanced project management, but the project management plan should specify appropriate approaches for several project levels as defined by factors in addition to dollar value. Project management should be included in an agency’s project development manual.

The collaboration of clinicians with basic science researchers is crucial for addressing clinically relevant research questions. In order to initiate such mutually beneficial relationships, we propose a model where early career clinicians spend a designated time embedded in established basic science research groups, in order to pursue a postgraduate qualification. During this time, clinicians become integral members of the research team, fostering long term relationships and opening up opportunities for continuing collaboration. However, for these collaborations to be successful there are pitfalls to be avoided. Limited time and funding can lead to attempts to answer clinical challenges with highly complex research projects characterised by a large number of "clinical" factors being introduced in the hope that the research outcomes will be more clinically relevant. As a result, the complexity of such studies and variability of its outcomes may lead to difficulties in drawing scientifically justified and clinically useful conclusions. Consequently, we stress that it is the basic science researcher and the clinician's obligation to be mindful of the limitations and challenges of such multi-factorial research projects. A systematic step-by-step approach to address clinical research questions with limited, but highly targeted and well defined research projects provides the solid foundation which may lead to the development of a longer term research program for addressing more challenging clinical problems. Ultimately, we believe that it is such models, encouraging the vital collaboration between clinicians and researchers for the work on targeted, well defined research projects, which will result in answers to the important clinical challenges of today.

Human computer interaction and interaction design have recognised the need for participatory methods of co-design to contribute to designing human-centred interfaces, systems and services. Design thinking has recently developed as a set of strategies for human-centred co-design in product innovation, management and organisational transformation. Both developments place the designer in a new mediator role, requiring new skills than previously evident. This paper presents preliminary findings from a PhD case study of strategy and innovation consultancy Second Road to discuss these emerging roles of design lead, facilitator, teacher and director in action.

More than ever before, architectural, engineering and construction (AEC) firms are working on international mega projects. The mega project environment offers a range of opportunities for firms but is but is characterised by a high level of risk and uncertainty. International mega projects bring together networks of people with differing backgrounds and cultures to work in unfamiliar locations to integrate the social, economic, technical and political components of design and construction. Within such an intense environment there is a process of rapid relationship development at an unprecedented level. The interests and power relations on such projects are often very strong given the vast amount of money, jobs, environmental impacts, publicity and national prestige involved. Therefore in a field as costly or consequential as mega project design and construction there is an increased need to effectively manage these projects given the associated high risks of failure. Internationalisation is a relatively new field of research in the AEC sector and past research has tended to focus on explaining the attitudes and behaviour of the industry itself towards improving performance on such projects. To date there has been little research investigating the sophistication of the international client in terms of their regular business environment which is characterised by a set of social, economic and political responsibilities. The values that clients ascribe to their everyday practices and experiences inevitably condition how they act economically, which in turn impacts upon project decision-making. Clients establish the structural organisation of project teams through the procurement strategy and establish the context for effective decision-making. To a large extent they establish a unique culture that project team members need to work within and make decisions. Since clients establish the context within which firms operate the findings of past studies on the industry’s position and attitudes are more indicative than enlightening. Clients occupy a distinctly different position in the construction supply chain and therefore experience and respond to project matters based upon their environment and not the construction industry environment. Clients are confronted with uncertainties and need support to help them understand the critical role that they play in creating good decision-making environments. This theoretical paper seeks to develop a rationale for studying the client’s complex decision-making environment on international mega projects. Specifically it charts the quest for improved industry performance through client leadership as documented in various industry and government publications since the 1940s and highlights that there has been considerable attention to address industry problems through client leadership, however, with little evidence that the issues have been resolved. This paper is positioned within a PhD study, which seeks to move beyond the aspirations of policymakers and idealistic descriptions of how clients ought to behave to explain the reality of what really happens on mega project client decision-making based upon a critique of cultural political economy.

The global construction environment offers stakeholders a range of opportunities but is characterised by a high level of risks and uncertainty. Internationalisation is a relatively new field of research in the AEC sector and past research has largely focused on explaining the behaviour of the industry itself. To date there has been little research investigating the client's leadership role. Much effort has been placed on positioning clients towards overall industry performance improvement, however, with little emphasis on the client's capacity to undertake their role. Clients establish the decision-making environment through key early critical decisions including procurement strategy and team membership. To a large extent they establish a unique culture that project team members need to work within and make decisions, which is the social and cultural embedding of the economic activities on projects. This theoretical paper is positioned within a PhD study which undertakes a cultural political economy perspective to investigate the client's central role in setting the boundaries within which decisions affecting budgets, quality, design, project organisational structure and team membership throughout the project lifecycle come to be made. A conceptual model for client leadership on international projects is developed based upon two contextual indicators which seeks to describe and explain the economic decisions clients make, which are deeply embedded in social relationships, shared meanings and cultural norms and the associated power and influence clients have on the political economy of international design and construction practice. This paper also seeks to develop a research question for future empirical testing.
