Project and product are two complementary facets of the lifecycle of any complex man-made system. The project focuses on the early phases of the system to be delivered, deployed, and supported, while the product focuses on the system itself - its function, structure, and behavior. Conceptual modeling and design is a major area common to both the project and the product, since evidently, the product is the deliverable of the project. Traditionally, however, the project and the product entities have been addressed as separate domains, each with its dedicated approaches, methods, and tools. This separation has hindered the integration of the project with the product it delivers, missing potential tangible benefits for all the stakeholders involved.
Systems Engineering Management (SEM) is an emerging practice that is being developed hand in hand with the maturation of systems engineering. Standards for SEM account for the intimate relationships between SEM and Project Management (PM) and highlight the criticality of these relationships in improving systems project management. While PM methods have traditionally focused on scheduling, budgeting, and scope management, SEM emphasizes the management of the project-product ensemble and issues related to the technologies of the system under development. The actual practice of systems engineering management involves continuous iterative zigzagging between the two domains - the systems engineering domain and the project management domain. This zigzagging is a cognitive process of understanding the intricate relationships between the product domain and the project domain, and planning the SEM efforts accordingly.
What the product-project ensemble has been lacking is a common underlying ontology, a conceptual model, and a supporting software environment. Attaining these missing elements enables the simultaneous expression of the function, structure and behavior of the project and the product. This thesis presents a model-based approach to managing the lifecycle of the product to be developed hand-in-hand with the lifecycle of the project, within the scope of which the product is developed. The cornerstone of this Project-Product Lifecycle Management (PPLM) approach is an underlying holistic conceptual model, supported by software capabilities for an integrated project and product lifecycle environment. The concurrent project-product model, built on common ontological foundations, enables better management, making it possible to directly link entities in one subsystem to those in the other. The expected value of the holistic, integrated conceptual model is the provision of both superior product lifecycle engineering and project management capabilities, yielding significant cut in time to market, reduced risk, and higher product quality.
