Attractive Work Process

Many companies both in Sweden and other parts of the world are since the beginning of the 21st century faceing a lack of work force (1,2,3). The ability to recruit and retain skilled employees is seen as one of the most important questions for the survival and development of the companies (4,5). Labour shortage is seen as the biggest obstacle for expansion for small enterprises in Sweden (5). There is a need for workplaces to be attractive, but how can the attractiveness be increased? Researchers at Högskolan Dalarna have during almost a decennium conducted research concerning attractive work. Based on a modell of qualities that contributes to make a work attractive (6) has a method aiming for raised attractiveness been developed for SME:s. All employees participate by answering a questionnaire about the importance of different qualities and to what degree they are fulfilled. Further discussions at the workplace on what to preserve and what to develop make the base for an action plan.Important experiences:• Discuss and establish the aim of the method with management and employees. • The company must be prepared to follow up and realize the action plan.• Agree about expectations – they must be realistic and practicable.• Reserve time to start the process and to end up in an action plan. • Avoid negative thinking and put problems away. • Take all the time small steps in the right direction.• Keep employees engaged and avoid the manager or process leader to take the command.• Use the strategy with small work groups; it gives better possibilities for participation and outspokenness.• Follow up studies are necessary to keep up the motivation.The most positive aspects of the method is its promoting perspective and that it engages all the employees.1.Rauhut, D.

Designing Agent-Oriented Systems by Analysing Agent Interactions

We propose a preliminary methodology for agent-oriented software engineering based on the idea of agent interaction analysis. This approach uses interactions between undetermined agents as the primary component of analysis and design. Agents as a basis for software engineering are useful because they provide a powerful and intuitive abstraction which can increase the comprehensiblity of a complex design. The paper describes a process by which the designer can derive the interactions that can occur in a system satisfying the given requirements and use them to design the structure of an agent-based system, including the identification of the agents themselves. We suggest that this approach has the flexibility necessary to provide agent-oriented designs for open and complex applications, and has value for future maintenance and extension of these systems.

Trust-By-Contract: Modelling, Analysing and Predicting Behaviour in Software Architectures

Architecture description languages (ADLs) are used to specify high-level, compositional views of a software application. ADL research focuses on software composed of prefabricated parts, so-called software components. ADLs usually come equipped with rigorous state-transition style semantics, facilitating verification and analysis of specifications. Consequently, ADLs are well suited to configuring distributed and event-based systems. However, additional expressive power is required for the description of enterprise software architectures – in particular, those built upon newer middleware, such as implementations of Java’s EJB specification, or Microsoft’s COM+/.NET. The enterprise requires distributed software solutions that are scalable, business-oriented and mission-critical. We can make progress toward attaining these qualities at various stages of the software development process. In particular, progress at the architectural level can be leveraged through use of an ADL that incorporates trust and dependability analysis. Also, current industry approaches to enterprise development do not address several important architectural design issues. The TrustME ADL is designed to meet these requirements, through combining approaches to software architecture specification with rigorous design-by-contract ideas. In this paper, we focus on several aspects of TrustME that facilitate specification and analysis of middleware-based architectures for trusted enterprise computing systems.

Electronic Business Contracts between Services

Electronic contracts mirror the paper versions exchanged between businesses today, and offer the possibility of dynamic, automatic creation and enforcement of restrictions and compulsions on service behaviour that are designed to ensure business objectives are met. Where there are many contracts within a particular application, it can be difficult to determine whether the system can reliably fulfil them all, yet computer-parsable electronic contracts may allow such verification to be automated. In this chapter, we describe a conceptual framework and architecture specification in which normative business contracts can be electronically represented, verified, established, renewed, and so on. In particular, we aim to allow systems containing multiple contracts to be checked for conflicts and violations of business objectives. We illustrate the framework and architecture with an aerospace aftermarket example.

Automating the product derivation process of multi-agent systems product lines

Agent-oriented software engineering and software product lines are two promising software engineering techniques. Recent research work has been exploring their integration, namely multi-agent systems product lines (MAS-PLs), to promote reuse and variability management in the context of complex software systems. However, current product derivation approaches do not provide specific mechanisms to deal with MAS-PLs. This is essential because they typically encompass several concerns (e.g., trust, coordination, transaction, state persistence) that are constructed on the basis of heterogeneous technologies (e.g., object-oriented frameworks and platforms). In this paper, we propose the use of multi-level models to support the configuration knowledge specification and automatic product derivation of MAS-PLs. Our approach provides an agent-specific architecture model that uses abstractions and instantiation rules that are relevant to this application domain. In order to evaluate the feasibility and effectiveness of the proposed approach, we have implemented it as an extension of an existing product derivation tool, called GenArch. The approach has also been evaluated through the automatic instantiation of two MAS-PLs, demonstrating its potential and benefits to product derivation and configuration knowledge specification.

Processo de escolha de bancos de imagens: aplicações no marketing business to business

The general objective of this research is to verify which attributes are most relevant to a stock photography agency that represent the purchaser's standards of choice. For this objective to be accomplished, qualitative interviews with the customers of stock photography agencies had been made in order to raise the attributes considered with relevance in the process of choice for the Brazilian stock photography agency market. The levels of each attribute to be tested had arisen through the mapping of the products and services offered by the competition and the relative weight assigned to each one of the attributes related to the research in the choices for a stock photography agency. A transversal study was made with a sample of stock photography agencies customers from Brazil¿s Southeastern region. For the analysis of this data, a survey method was used, that, according to MALHOTRA (2006: 182), involves a structuralized questionnaire to be answered by an interview that elucidates specific information, in which the questions had a predetermined order. This questionnaire was presented through interviews on the Internet. The method adopted for this analysis was a joint analysis. A sampling of 1000 customer stock photography agencies were selected, which were represented by a didactic book editor, advertising agencies, editorial companies, etc., in the states of Rio de Janeiro, São Paulo, Espírito Santo and Minas Gerais. They had been obtained by 16 stimulations, or cards, for the application of the companies. Of the sample of 1000 customers of stock photography agencies, 7,8% responded to the research. The attribute most relevant in accordance with the presented results is the availability of images in high resolution for layout. Its relative importance was 40,78%. At the end of the study, the management implications were propitiated to the stock photography agencies managers inabling them to be more competitive.
