Managing enterprises and ERP systems:a contingency model for the enterprization of operations

Purpose: The purpose of this paper is to investigate enterprise resource planning (ERP) systems development and emerging practices in the management of enterprises (i.e. parts of companies working with parts of other companies to deliver a complex product and/or service) and identify any apparent correlations. Suitable a priori contingency frameworks are then used and extended to explain apparent correlations. Discussion is given to provide guidance for researchers and practitioners to deliver better strategic, structural and operational competitive advantage through this approach; coined here as the "enterprization of operations". Design/methodology/approach: Theoretical induction uses a new empirical longitudinal case study from Zoomlion (a Chinese manufacturing company) built using an adapted form of template analysis to produce a new contingency framework. Findings: Three main types of enterprises and the three main types of ERP systems are defined and correlations between them are explained. Two relevant a priori frameworks are used to induct a new contingency model to support the enterprization of operations; known as the dynamic enterprise reference grid for ERP (DERG-ERP). Research limitations/implications: The findings are based on one longitudinal case study. Further case studies are currently being conducted in the UK and China. Practical implications: The new contingency model, the DERG-ERP, serves as a guide for ERP vendors, information systems management and operations managers hoping to grow and sustain their competitive advantage with respect to effective enterprise strategy, enterprise structure and ERP systems. Originality/value: This research explains how ERP systems and the effective management of enterprises should develop in order to sustain competitive advantage with respect to enterprise strategy, enterprise structure and ERP systems use. © Emerald Group Publishing Limited.

The effects of material variations in high value manufacturing industries

It has never been easy for manufacturing companies to understand their confidence level in terms of how accurate and to what degree of flexibility parts can be made. This brings uncertainty in finding the most suitable manufacturing method as well as in controlling their product and process verification systems. The aim of this research is to develop a system for capturing the company’s knowledge and expertise and then reflect it into an MRP (Manufacturing Resource Planning) system. A key activity here is measuring manufacturing and machining capabilities to a reasonable confidence level. For this purpose an in-line control measurement system is introduced to the company. Using SPC (Statistical Process Control) not only helps to predict the trend in manufacturing of parts but also minimises the human error in measurement. Gauge R&R (Repeatability and Reproducibility) study identifies problems in measurement systems. Measurement is like any other process in terms of variability. Reducing this variation via an automated machine probing system helps to avoid defects in future products.Developments in aerospace, nuclear, oil and gas industries demand materials with high performance and high temperature resistance under corrosive and oxidising environments. Superalloys were developed in the latter half of the 20th century as high strength materials for such purposes. For the same characteristics superalloys are considered as difficult-to-cut alloys when it comes to formation and machining. Furthermore due to the sensitivity of superalloy applications, in many cases they should be manufactured with tight tolerances. In addition superalloys, specifically Nickel based, have unique features such as low thermal conductivity due to having a high amount of Nickel in their material composition. This causes a high surface temperature on the work-piece at the machining stage which leads to deformation in the final product.Like every process, the material variations have a significant impact on machining quality. The main cause of variations can originate from chemical composition and mechanical hardness. The non-uniform distribution of metal elements is a major source of variation in metallurgical structures. Different heat treatment standards are designed for processing the material to the desired hardness levels based on application. In order to take corrective actions, a study on the material aspects of superalloys has been conducted. In this study samples from different batches of material have been analysed. This involved material preparation for microscopy analysis, and the effect of chemical compositions on hardness (before and after heat treatment). Some of the results are discussed and presented in this paper.

Projectos de consultoria em SAP e tecnologias microsoft: análise e desenvolvimento de soluções de software à medida

À medida que a sociedade evolui, também as profissões evoluem com ela. Uma profissão que tem crescido de forma notável é a de consultor na área das tecnologias de informação. De facto, há alguns anos atrás, esta profissão não tinha o relevo que tem na actualidade, pois com a evolução das tecnologias da informação, as ferramentas ao dispor das empresas diversificaram-se e como tal, a mão-de-obra vai-se especializando nestas ferramentas. As empresas, na impossibilidade de contratar mão-de-obra para instalar, manter e evoluir todas as suas ferramentas, recorrem cada vez mais à experiência de consultores externos; estes são contratados para realizar tarefas específicas que as empresas não têm capacidade de executar com os próprios recursos e a sua ligação com estas entidades termina após a conclusão destas tarefas. Cada vez mais as empresas procuram tirar o máximo partido das ferramentas informáticas à sua disposição e os sistemas de Enterprise Resource Planning não são excepção. À medida que os utilizadores vão usufruindo dos sistemas, surgem novas necessidades que, depois de colmatadas, permitem a sua optimização. Além disso, com a alteração das leis, é preciso adaptar os sistemas para que estes evoluam e possam reflectir os novos requisitos legais. Com o aumento da regulação bancária, as entidades bancárias são obrigadas a comunicar informação sobre as suas finanças ao Banco de Portugal, de modo a que o banco possa analisar a saúde financeira das entidades e emitir recomendações sobre a sua forma de actuar. Esta nova forma de comunicação será efectuada por meio de relatórios em eXtended Business Reporting Language (XBRL). Pretende-se caracterizar a profissão de consultor e apresentar alguns projectos realizados enquanto consultor numa consultora de grande dimensão.

Fatores críticos de sucesso como antecedentes da aceitação de um sistema de informação em uma universidade federal

In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ²) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public.

Project Resource Management in R&D Public Sector Organization

In R&D organizations multiple projects are executed concurrently. Problems arises in managing shared resources since they are needed by multiple projects simultaneously. The objective of this thesis was to study how the project and resource management could be developed in a public sector R&D organization. The qualitative research was carried out in the Magnetic Measurements section at CERN where the section measures magnets for particle accelerators and builds state of the art measurement devices for various needs. Hence, the R&D and measurement projects are very time consuming and very complex. Based on the previous research and the requirements from the organization the best alter- native for resource management was to build a project management information system. A centralized database was constructed and on top of it was built an application for interacting and visualizing the project data. The application allows handling project data, which works as a basis for resource planning before and during the projects are executed. It is one way to standardize the work-flow of projects, which strengthens the project process. Additionally, it was noted that the inner customer’s database, the measurement system and the new application needed to be integrated. Further integration ensures that the project data is received efficiently from customers and available not only within the application but also during the concrete work. The research results introduced a new integrated application, which centralizes the project information flow with better visibility.

An integrated assessment of resource use strategies in the Borana pastoral system of southern Ethiopia

In the pastoral production systems, mobility remains the main technique used to meet livestock’s fodder requirements. Currently, with growing challenges on the pastoral production systems, there is urgent need for an in-depth understanding of how pastoralists continue to manage their grazing resources and how they determine their mobility strategies. This study examined the Borana pastoralists’ regulation of access to grazing resources, mobility practices and cattle reproductive performances in three pastoral zones of Borana region of southern Ethiopia. The central objective of the study was to contribute to the understanding of pastoral land use strategies at a scale relevant to their management. The study applied a multi-scalar methodological approach that allowed zooming in from communal to individual herd level. Through participatory mapping that applied Google Earth image print out as visual aid, the study revealed that the Borana pastoralists conceptualized their grazing areas as distinctive grazing units with names, borders, and specific characteristics. This knowledge enables the herders to communicate the condition of grazing resources among themselves in a precise way which is important in management of livestock mobility. Analysis of grazing area use from the participatory maps showed that the Borana pastoralists apportion their grazing areas into categories that are accessed at different times of the year (temporal use areas). This re-organization is an attempt by the community to cope with the prevailing constraints which results in fodder shortages especially during the dry periods. The re-organization represents a shift in resource use system, as the previous mobility practice across the ecologically varied zones of the rangelands became severely restricted. Grazing itineraries of 91 cattle herds for over 16 months obtained using the seasonal calendar interviews indicated that in the areas with the severest mobility constraints, the herders spent most of their time in the year round use areas that are within close proximity to the settlements. A significant change in mobility strategy was the disallowing of foora practice by the communities in Dirre and Malbe zones in order to reduce competition. With the reduction in mobility practices, there is a general decline in cattle reproductive parameters with the areas experiencing the severest constraints showing the least favourable reproductive performances. The study concludes that the multi-scalar methodology was well suited to zoom into pastoral grazing management practices from communal to individual herd levels. Also the loss of mobility in the Borana pastoral system affects fulfilment of livestock feed requirements thus resulting in reduced reproductive performances and herd growth potentials. While reversal of the conditions of the situations in the Borana rangelands is practically unfeasible, the findings from this research underscore the need to protect the remaining pastoral lands since the pastoral production system remains the most important livelihood option for the majority of the Borana people. In this regards the study emphasises the need to adopt and domesticate regional and international policy frameworks such as that proposed by the African Union in 2010.

Planning “Discrete” Movements Using a Continuous System: Insights from a Dynamic Field Theory of Movement Preparation

The timed-initiation paradigm developed by Ghez and colleagues (1997) has revealed two modes of motor planning: continuous and discrete. Continuous responding occurs when targets are separated by less than 60° of spatial angle, and discrete responding occurs when targets are separated by greater than 60°. Although these two modes are thought to reflect the operation of separable strategic planning systems, a new theory of movement preparation, the Dynamic Field Theory, suggests that two modes emerge flexibly from the same system. Experiment 1 replicated continuous and discrete performance using a task modified to allow for a critical test of the single system view. In Experiment 2, participants were allowed to correct their movements following movement initiation (the standard task does not allow corrections). Results showed continuous planning performance at large and small target separations. These results are consistent with the proposal that the two modes reflect the time-dependent “preshaping” of a single planning system.

Challenges for an Integrated Water Resource Management in the Merguellil basin (Tunisia)

La risorsa acqua in zone semi-aride è sottoposta a un'estrema variabilità climatica nello spazio e nel tempo. La gestione della risorsa acqua è quindi soggetta a un insieme di sfide quando i vincoli naturali vengono uniti agli effetti indotti da attività umana come per esempio l'aumento dello sfruttamento dell'acqua di sottosuolo, cambiamento dell'uso del suolo e presenza di infrastruttura mista. Si spera che il cambiamento climatico e l'attività risultanti dallo sviluppo economico, a corto termine aumentino la pressione su un sistema ormai sensibile. Se pianificato e gestito correttamente, lo stoccaggio dell'acqua, nelle sue varie forme, funge come un meccanismo di controllo della variabilità climatica e può potenziare la capacità adattiva. Lo uadi Merguellil è un corso d'acqua a carattere non perenne al centro della Tunisia, più specificamente a est della città di Kairouan. Il Merguellil drena la pioggia sulla dorsale Tunisina insieme al uadi Zeroud e Nebhana, ed è tra i principali fiumi che scorre sulla piana di Kairouan. Lo stoccaggio dell'acqua nel bacino assume diverse forme come i laghi collinari, i terrazzi, acqua di sottosuolo e una diga. Alcune delle opzioni per lo stoccaggio dell'acqua sono state costruite per preservare la risorsa acqua, mantenere la popolazione rurale e mantenere l'equità tra le zone a monte ed a valle ma solitamente non è mai stata fatta un'analisi comprensiva dei "trade-offs" coinvolti in tali sviluppi. Anche se la ricerca è sviluppata in questa zona, finora nessuna analisi ha cercato di combinare le dinamiche del sistema idrologico con scenari gestionali. L'analisi di scenari gestionali consente ai decisori di valutare delle alternative di pianificazione e può incrementare positivamente la loro abilità di creare delle politiche che si basino sulle necessità fisiche ma anche sociali di un particolare sistema. Questo lavoro è un primo passo verso un Sistema di Gestione Integrata della Risorsa Idrica (inglese: IWMR) capace di mettere in prospettiva strategie future su diverse scale. L'uso di uno strumento metodologico illustra le sfide associate nell'affrontare questo compito. In questo caso, un modello WEAP (Water Evaluation and Planning System) è stato sviluppato in collaborazione con partners Tunisini in modo da integrare le conoscenze su processi fisici e valutare diverse tendenze come l'aumento dell'irrigazione o il cambio di alcuni aspetti climatici. Lo strumento ora è disponibile ai ricercatori locali dove potrà essere sviluppato ulteriormente a fine di indirizzare domande più specifiche. Questo lavoro focalizza lo stoccaggio dell'acqua per poter evidenziare le interazioni dinamiche tra le diverse opzioni di stoccaggio nella zona di studio e valutare i "trade-offs" tra di esse. I risultati iniziali dimostrati in questo lavoro sono: - Se lo sfruttamento degli acquiferi fosse ristretto ai livelli delle loro ricarica, la domanda d'acqua dei diversi utilizzatori non sarebbe soddisfatta al 25% dei livelli di consumo attuale. - La tendenza di incremento dell'agricoltura di irrigazione crea un impatto più accentuato nelle risorse di sottosuolo di quello creato da un'ipotetica riduzione della piovosità all'85% - L'aumento del numero di laghi collinari riduce la quantità d'acqua che arriva a valle, allo stesso tempo aumenta la quantità d'acqua "persa" per evaporazione.
