UER technique: conceptualisation for agent oriented development

The problem of conceptualisation is the first step towards the identication of the functional requirements of a system. This article proposes two extensions of well-known object oriented techniques: UER (User-Environment-Responsibility) technique and enhanced CRC (Class-ResponsibilityCollaboration) cards. UER technique consists of (a) looking for the users of systems and describing the ways the system is used; (b) looking for the objects of the environment and describing the possible interactions; and (c) looking for the general requirements or goals of the system, the actions that it should carry out without explicit interaction. The enhanced CRC cards together with the internal use cases technique is used for dening collaborations between agents. These techniques can be easily integrated in UML (Unied Modelling Language) [2], dening the new notation symbols as stereotypes.

An Integrated Approach to Strategic Asset Management

This paper focuses on identifying and analysing the elements of Strategic Management for infrastructure and engineering assets. These elements are contended to involve an understanding of governance, corporate policy, corporate objectives, corporate strategy and interagency collaboration and will in turn, allow the ability determine a broader and more comprehensive framework for engineering asset management, ie a ‘staged approach’ to understanding how assets are managed within organisations. While the assets themselves have often been the sole concern for good management practices, other social and contextual elements have come into the mix in order to promote strategic asset management. The development of an integrated approach to asset management is at the base of the research question. What are the considerations and implications for adopting and implementing an integrated strategic asset management (ISAM) framework? While operational matters have been given prominence, a subset of corporate governance, Asset Governance, details the policies and processes needed to acquire, utilise, maintain and account for an organisation’s assets. Asset governance stems from the organisation’s overarching corporate governance principles; as a result it defines the management context in which engineering asset management is implemented. This aspect will be examined to determine the appropriate relationship between organisational strategic management and strategic asset management to further the theoretical engagement with the maturity of strategy,policy and governance for infrastructure and engineered assets. Asset governance stems from the organisation’s overarching corporate governance principles; as a result it defines the management context in which engineering asset management is implemented. The research proceeds by a document analysis of corporate reports and policy recommendations in terms of infrastructure and engineered assets. The paper concludes that incorporating an integrated asset management framework can promote a more robust conceptualisation of public assets and how they combine to provide a comprehensive system of service outcomes.
