Product Life-Cycle Management Flashcards
Architecture Definition
Fundamental orgzn of a system embodied in its components, their relationships to each other, and to the environment, and the principles guiding its design and evolution
“Baseline” Definition
Specification or Pd that has been formally reviewed and agreed upon, that thereafter serves as the basis for further development, and that can be changed only through formal change control procedures
“Life cycle” Definition
“Life Cycle model” Definition
Evolution of a system, Pd, service, project, or entity from conception through retirement
Framework of processes and activities concerned with the LC that may be organized into stages, which also acts as a common reference for communication and understanding
Note: A LC model is a decision-linked conceptual segmentation of the definition of the need for the system, its realization as a Pd or service, and its utilization, evolution and disposal

Significance of Concept Stage
Purpose: Assess new business opportunities and to develop preliminary system requirements and a feasible design solution
(1) Begins with initial recognition of a need or a requirement for a new System-of-interest or for the modification to an existing system-of-interest
(2) This is is an initial exploration, fact finding, and planning period when economic, technical, strategic, and market bases are assessed through acquirer/market survey, feasibility analysis and trade-off studies. User feedback to the concept is obtained
Activities involved in Concept stage
(1) One or more alternative concepts to meet he identified need or requirement are developed through
(a) Analysis
(b) Feasibility evaluations
(c) Estimations (Cost, schedule, market intelligence, and logistics)
(d) trade-off studies
(e) Experimental or prototype development
(f) Demonstration
(2) Need for one or more enabling systems for development, production of “system-of-interest” is identified and candidate solutions are included in the evaluation of alternatives in order to arrive at balanced, LC solution
Outcomes of Concept stage
- Identification of new concepts that offer such things as new capabilities, enhanced overall performance, or reduced stakeholder’s total ownership costs
- Assessment of feasible concepts and solutions, for closure against both technical and business stakeholder objectives
- Preparation and baselining of stakeholder reqts and preliminary system reqts (technical specs and usability specs)
- Risk identification, assessment and mitigation plans
- Concepts for execution of all succeeding stages
- Plans and exit criteria for Development stage
- Development and satisfaction of stage exit criteria
- Cost estimates for succeeding stages
Significance of Development stage
Purpose: Develop a system-of-interest that meets stakeholder requirements and can be produced, tested, evaluated, operated, supported and retired
Activities involved:
Technical processes referenced above
Outcome of Development stage
- Baselined technical information, including evaluated and refined system requirements and:
a. Hardware diagrams, drawings and models
b. Software design documentation
c. Interface specifications
d. Production plans
e. Operating Instructions
f. Training manuals for operations
g. Maintenance procedures
h. Retirement considerations - Project budget and schedule baselines and LC ownership cost estimates
- System of interest
- Verification and Validation documentation
- Refined cost estimates for Production, utilization and retirement stages
- Approval to proceed to production stage
