In recent years, advances in information technology and enterprise engineering have revolutionised the way businesses are conducted. Enterprises. are complicated organisations consisting of 'artefacts' (enterprise structure, activities, processes, information, resources, behaviour, goals, and constraints) that must be coordinated, planned and engineered to accomplish the enterprise goals. Enterprise engineering is an engineering approach comprised of techniques, methods, and infrastructures to aid the design, analysis, and implementation of an enterprise system. However, many modellers forgo the enterprise modelling methods and techniques and use localised ad-hoc and point solutions that are not amenable for enterprise infrastructure design. The current methods and techniques available are ill-equipped to model the holistic requirements oftoday's complex enterprises. .' This research adopts the PAM (problem Articulation Method), rooted in semiotics, a study of signs, symbols, language and information. PAM offers a suite of techniques, which enables the articulation and analysis of business, technical and organisational requirements, delivering a rigorous enterprise infrastructure to support the model. The method works by eliciting and formalising project planning and modelling (processes, .activities, relationships, responsibilities, communications, resources, agents, dependencies and constraints), where the abstractions are mapped to represent the manifestation ofthe 'actual' enterprise. ~ .,J The proposed enterprise framework incorporates PAM and MEASUR (Methods for Eliciting Analysing and Specifying Users Requirements) a suite of semiotics methods to model the agent's ontological relationships, defining its meaning (semantics) to improve the analytical capability of the model and elicit the normative behaviours of agents to enrich the enterprise model. The PAM method has been further extended to examine the method relevance and significance in dealing with innovation in the modelling and planning of complex enterprise projects. The PAM conceptual model created is subsequently analysed, tested and verified using an off-the-shelf discreteevent simulation software, to be modelled dynamically. The simulation models are also validated by the domain experts from the respective organisations to assess the consistency, coherence and logical correctness of the 'model. This modelling approach contributed to the further development of the PAM theories, methods and techniques and represents a significant improvement to facilitate enterprise infrastructure planning and in so doing, exploit the technological, business and organisational effectiveness.
