The design and development of general Product Life Cycles (PLC) and Enterprise Life Cycles (ELC) has received significant attention over the past years. The EDENTM Software Environment developed from Indutech (Pty) Ltd provides roadmaps for both life cycles. These roadmaps allow the involved development team to follow a predefined step-by-step structure for their respective project.
As a PLC always belongs to a superior ELC, both life cycles cannot be considered independently. Changes and decisions of one of the life cycles usually have an impact on the other. And although the PLC and ELC are well explored, there does not exist a model which reveals those important interfaces between both life cycles.
This thesis aims on the detection of impacts of the PLC on the ELC. As the Design Review (DR) is a crucial key control element in the development process, the detection of the links is done by means of such DR. After giving general information about DR and providing definitions and descriptions of DR in the PLC and ELC, an impact-matrix is developed which shows the detected interference of the ELC by decisions of DR conducted in the PLC.

Objectives and Topics
This thesis examines the relationship between Product Life Cycles (PLC) and Enterprise Life Cycles (ELC). Its primary goal is to develop a model that identifies and evaluates the impacts of design decisions made during a PLC on the underlying ELC, filling a gap in existing literature where these life cycles are often treated independently despite their inherent interdependence.
- Methodologies of Design Reviews (DR) as a control element.
- Structural mapping of interactions between PLC and ELC.
- Impact analysis of PLC development phases on enterprise architectures.
- Development of a comprehensive PLC-ELC impact matrix.
- Strategic decision-making for enterprise resource and process planning.
Excerpt from the Book
3.2.1 Project Initialisation Meeting
Definition: The Project Initialisation Meeting (PIM) initiates the Concept Phase of a new PLC. In this meeting, the project’s scope and objectives are developed on a high level, including supportive detail. Furthermore it is a basic feasibility study of the whole project, and a successful verification of this project introduces the Concept Phase.
Description: When the need for a new or refreshed product or, more general, a change in market orientation of the enterprise is established, a Project Initialisation Meeting is initiated and a project is started. A project management team is set up and many formal processes like registering the project, allocating resources to the various tasks, defining the project goals and outcomes, and planning the project broadly according to the required standards, are accomplished.
The main processes of this phase are, according to /MYRI98/:
• Feasibility Study and Risk Research
• Executive Level Support and Sponsorship Establishment
• Formal Project Initialization
• Lead Project Personnel Assignment
• Key Stake Holder and Knowledge Resource Identification
• Project Advisory Committee Initialization
• Project Team Development
• Preliminary Project Scope Development
• Preliminary Project Objective Statement Development
• Preliminary Inventory Development
• Preliminary Cost and Resource Projections Development
• High Level Project Management Planning
Tangible end results of the PIM include a detailed project work plan complete with timeframes, a project charter document, a project standards document, and risk and communication plans /KAVA01/.
