Steering without Circe : attending to reinforcing loops in social systems

Relating system dynamics to the broad systems movement, the key notion is that reinforcing loops deserve no less attention than balancing loops. Three specific propositions follow. First, since reinforcing loops arise in surprising places, investigations of complex systems must consider their possible existence and potential impact. Second, because the strength of reinforcing loops can be misinferred - we include an example from the field of servomechanisms - computer simulation can be essential. Be it project management, corporate growth or inventory oscillation, simulation helps to assess consequences of reinforcing loops and options for interventions. Third, in social systems the consequences of reinforcing loops are not inevitable. Examples concerning globalization illustrate how difficult it might be to challenge such assumptions. However, system dynamics and ideas from contemporary social theory help to show that even the most complex social systems are, in principle, subject to human influence. In conclusion, by employing these ideas, by attending to reinforcing as well as balancing loops, system dynamics work can improve the understanding of social systems and illuminate our choices when attempting to steer them.

Design meetings and the coordination of expertise

The coordination of work and expertise in construction projects is often treated in terms of models or formal rules. However, much is to be gained, if we are to understand it, by examining actual coordination practices. The objective in this article is to address practices of coordination of expertise in the context of design team meetings. The focus is specifically on conversational practices between the structural engineer and the landscape architect part of the design team in a healthcare infrastructure project. The central argument is that the coordination of expertise relied on and was organised by mundane and everyday methods, and not by formal and abstract ones. This argument is drawn from ethnomethodology, a form of sociological analysis that focuses on the situated methods by which activities are produced, but shares concerns found in the literature on actual project management practices. The ethnomethodological stance, however, offers a different perspective on the significance of the empirical reality of projects and a possibility to incorporate within this literature a concern with the ordinary methodical organisation of project activities.

Operating models for a multi-polar world: balancing global integration and local responsiveness

Purpose – Multinationals have always needed an operating model that works – an effective plan for executing their most important activities at the right levels of their organization, whether globally, regionally or locally. The choices involved in these decisions have never been obvious, since international firms have consistently faced trade‐offs between tailoring approaches for diverse local markets and leveraging their global scale. This paper seeks a more in‐depth understanding of how successful firms manage the global‐local trade‐off in a multipolar world. Design methodology/approach – This paper utilizes a case study approach based on in‐depth senior executive interviews at several telecommunications companies including Tata Communications. The interviews probed the operating models of the companies we studied, focusing on their approaches to organization structure, management processes, management technologies (including information technology (IT)) and people/talent. Findings – Successful companies balance global‐local trade‐offs by taking a flexible and tailored approach toward their operating‐model decisions. The paper finds that successful companies, including Tata Communications, which is profiled in‐depth, are breaking up the global‐local conundrum into a set of more manageable strategic problems – what the authors call “pressure points” – which they identify by assessing their most important activities and capabilities and determining the global and local challenges associated with them. They then design a different operating model solution for each pressure point, and repeat this process as new strategic developments emerge. By doing so they not only enhance their agility, but they also continually calibrate that crucial balance between global efficiency and local responsiveness. Originality/value – This paper takes a unique approach to operating model design, finding that an operating model is better viewed as several distinct solutions to specific “pressure points” rather than a single and inflexible model that addresses all challenges equally. Now more than ever, developing the right operating model is at the top of multinational executives' priorities, and an area of increasing concern; the international business arena has changed drastically, requiring thoughtfulness and flexibility instead of standard formulas for operating internationally. Old adages like “think global and act local” no longer provide the universal guidance they once seemed to.

An investigation of the required skills for the delivery of low and zero carbon buildings within a region

The United Kingdom is committed to a raft of requirements to create a low-carbon economy. Buildings consume approximately 40% of UK energy demand. Any improvement on the energy performance of buildings therefore can significantly contribute to the delivery of a low-carbon economy. The challenge for the construction sector and its clients is how to meet the policy requirements to deliver low and zero carbon (LZC) buildings, which spans broader than the individual building level, to requirements at the local and regional levels, and wider sustainability pressures. Further, the construction sector is reporting skills shortages coupled with the need for ‘new skills’ for the delivery of LZC buildings. The aim of this paper is to identify, and better understand, the skills required by the construction sector and its clients for the delivery of LZC buildings within a region. The theoretical framing for this research is regional innovation system (RIS) using a socio-technical network analysis (STNA) methodology. A case study of a local authority region is presented. Data is drawn from a review of relevant local authority documentation, observations and semi-structured interviews from one (project 1) of five school retrofit projects within the region. The initial findings highlight the complexity surrounding the form and operation of the LZC network for project 1. The skills required by the construction sector and its clients are connected to different actor roles surrounding the delivery of the project. The key actors involved and their required skills are: project management and energy management skills required by local authority; project management skills (in particular project planning), communication and research skills required by school end-users; and a ‘technical skill’ relating to knowledge of a particular energy efficient measure (EEM) and use of equipment to implement the EEM is required by the EEM contractors.

Mathematical relationships between scoring parameters in capped tendering

Mathematical relationships between Scoring Parameters can be used in Economic Scoring Formulas (ESF) in tendering to distribute the score among bidders in the economic part of a proposal. Each contracting authority must set an ESF when publishing tender specifications and the strategy of each bidder will differ depending on the ESF selected and the weight of the overall proposal scoring. This paper introduces the various mathematical relationships and density distributions that describe and inter-relate not only the main Scoring Parameters but the main Forecasting Parameters in any capped tender (those whose price is upper-limited). Forecasting Parameters, as variables that can be known in advance before the deadline of a tender is reached, together with Scoring Parameters constitute the basis of a future Bid Tender Forecasting Model.

On competitive bidding: scoring and position probability graphs

Iso-score curves graph (iSCG) and mathematical relationships between Scoring Parameters (SP) and Forecasting Parameters (FP) can be used in Economic Scoring Formulas (ESF) used in tendering to distribute the score among bidders in the economic part of a proposal. Each contracting authority must set an ESF when publishing tender specifications and the strategy of each bidder will differ depending on the ESF selected and the weight of the overall proposal scoring. The various mathematical relationships and density distributions that describe the main SPs and FPs, and the representation of tendering data by means of iSCGs, enable the generation of two new types of graphs that can be very useful for bidders who want to be more competitive: the scoring and position probability graphs.

Improving the estimation of probability of bidder participation in procurement auctions

Anticipating the number and identity of bidders has significant influence in many theoretical results of the auction itself and bidders' bidding behaviour. This is because when a bidder knows in advance which specific bidders are likely competitors, this knowledge gives a company a head start when setting the bid price. However, despite these competitive implications, most previous studies have focused almost entirely on forecasting the number of bidders and only a few authors have dealt with the identity dimension qualitatively. Using a case study with immediate real-life applications, this paper develops a method for estimating every potential bidder's probability of participating in a future auction as a function of the tender economic size removing the bias caused by the contract size opportunities distribution. This way, a bidder or auctioner will be able to estimate the likelihood of a specific group of key, previously identified bidders in a future tender.

Upplevda problem med projektstyrningsmetoden Scrum i systemutvecklingsprojekt : En studie av Scrums-relaterade problem hos IT- företag i Borlängeregion

Många projekt misslyckas och en av anledningarna är dålig styrning av projektet i allmänhet och inom IT branschen i synnerhet. Baserad på kritik av de traditionella metoderna under de senaste åren, så har det uppkommit flera lättrörliga metoder som kallas Agila metoder. Scrum är den mest kända Agila metoden som används idag. Metoden lovar goda resultat, men i en artikel ur tidningen Computer Sweden (feb 2009) står det ”siffror visar att nio av tio Scrumprojekt misslyckas”. Artikeln triggade vårt intresse av att ta reda på vilka problem specifika för Scrum som många har kritiserat och valde därför att rikta in vår studie mot detta. Uppsatsen syftar till att undersöka om lokala IT-företag i Borlänge, Headlight, Sogeti ochstatliga nätkapacitetleverantören Trafikverket ICT lider av det allmänna problem som de andra Scrumanvändarna upplever i samband med användningen av metoden. Denna uppsats har fokus på fyra problemområden: bristfällig dokumentation, sämre effektivitet i arbetsprocessen, sämre effektivitet i arbetsprocessen i stora projekt samt bristande stöd för utvärdering. För vår studie har litteraturstudier och intervjuer genomförts. Intervjuserier gjordes på elva personer hos våra fallföretag. Målgruppen för våra intervjuer är Product Owner (PO) ScrumMaster (SM) och utvecklare. Vi kan efter genomförd studie dra slutsatsen att de allmänna upplevda problem som de andra Scrumanvändaren upplever har vi även kunnat identifiera hos våra fallföretag. Resultaten har bekräftats med insamlade data och vår teoretiska ram. I diskussionen presenterar vi rekommendationer för att undvik relaterade problem med Scrum.

Kostnader och risker med internationell verksamhet i Mexiko

Detta examensarbetes syfte är att identifiera vilka faktorer som påverkar kostnader och risker som kan finnas vid internationellt företagande i Mexiko utifrån ett perspektiv där företagande samt företagsomgivningar vanligtvis är stöttande och välfungerande. En litteraturstudie utfördes på Internationella verksamheter (International Business), och skapade intervjuunderlaget som användes för att intervjua företagare i Mexiko med erfarenheter av både internationell verksamhet samt USA/EU, och enbart erfarenheter från företagande inom landet. Resultat visar att det finns sex stycken samlingsområden som påverkar kostnader och risker; Politiska faktorer som innebär att drastiska förändringar orsakas i ett lands affärsomgivning, och som negativt påverkar ett företags vinster eller andra mål; Ekonomiska faktorer som innebär att det kostar mer att ha verksamhet på grund av brister inom infrastruktur och stödjande verksamheter; Den ekonomiska utvecklingen; Det finns utbredd korruption hos Mexikanska myndigheter på både lokal- och statsnivå; Ledningsprocesser och metoder kan behöva anpassas enligt kulturellt bestämda arbetsrelaterade värderingar; och Internationella verksamheter bör anställa lokala individer till hjälp att utföra affärer inom en specifik kultur.

Inovação e gestão de projetos: os "fins" justificam os "meios"

O advento da globalização, a evolução dos meios de comunicação, aliados ao progresso dos recursos de tecnologia da informação, impuseram uma dinâmica de aceleração progressiva aos processos de mudança em geral. Este fenômeno tem feito com que, cada vez mais, as organizações busquem e renovem seus instrumentos de gestão, em prol do aprimoramento de atividades e processos que lhes garantam a inovação de um determinado produto e/ou serviço. Ao mesmo tempo em que a globalização torna os mercados mais competitivos, o “cliente moderno” passa a ter mais opções e a ser mais exigente. Diante desta realidade, é preciso que as organizações se adaptem a este novo cenário, de forma a cada vez mais oferecerem produtos e/ou serviços com maior qualidade e a preços mais competitivos. Entre as medidas que podem ser tomadas para alcançar este objetivo, encontra-se a prática de gerenciar projetos de uma forma mais profissional e planejada. E para auxiliar os gerentes nesta prática, um campo da administração está em ascensão: a Gestão de Projetos a partir da metodologia do Project Management Institute (PMI). Com as constantes fusões, aquisições e, consequentemente, diversificações dos negócios das organizações no atual mundo globalizado, o gerenciamento de projetos pode ser uma opção para que as organizações superem seus desafios e obstáculos relacionados à inovação e, ao mesmo tempo, alcancem seus objetivos de resultados e crescimentos almejados. Enfim, este ensaio teórico se propõe a debater a inovação e a gestão de projetos nas organizações contemporâneas, onde a primeira são os “fins” e a segunda, os “meios”.

Um método para definição de indicadores de desempenho aplicado à gestão de projetos de sistemas de informação

O presente trabalho apresenta a investigação realizada sobre a utilização de indicadores de desempenho para tomada de decisões na implementação de projetos de sistemas. Para a realização desta pesquisa, utilizou-se como revisão da literatura a metodologia do Project Management Institute, que aborda o gerenciamento dos projetos de sistemas e o conceito do Balanced Scorecard, que trata da utilização de indicadores na implementação das estratégias. Utilizou-se o BSC para se enfatizar o relacionamento entre os resultados dos projetos e as estratégias. Com auxílio de uma metodologia de natureza qualitativa, buscou-se, através de entrevistas semiestruturadas, identificar as experiências dos entrevistados (quinze executivos) acerca da utilização de indicadores de desempenho. Estas contribuições foram estruturadas em quatro etapas: dificuldades encontradas na implementação de sistemas de indicadores, aspectos a serem monitorados nos projetos, indicadores nas perspectivas e lições aprendidas. A partir da revisão da literatura e resultado da análise das entrevistas, propõe-se no capítulo 5 um roteiro para identificação de projetos prioritários e identificação dos indicadores-chave para gestão dos projetos.

O Gerenciamento de projetos segundo a teoria das restrições

Este trabalho discute a questão do Gerenciamento de Projetos, atividade que vem crescendo em importância nos nossos dias. Inicialmente foi feita uma revisão geral sobre o conhecimento acumulado em Gerenciamento de Projetos, mostrando a seguir que, apesar de toda a evolução desta metodologia, os problemas para terminar um projeto dentro do prazo, com as características desejadas e mantendo os custos dentro do orçamento previsto, ainda falham. A Teoria das Restrições mostrou-se útil na redução dessas falhas cujas causas principais foram mostradas; uma metodologia é proposta para eliminá-las. Finalmente foi feita uma pesquisa exploratória em dez empresas de diferentes ramos e dimensões que aplicaram essa metodologia com uma análise sobre a adequação de sua utilização.
