According to ISO/IEC/IEEE 15288, what are the four process groups that organize system life cycle processes?
Answer: Agreement, Organizational Project-Enabling, Technical Management, Technical
ISO/IEC/IEEE 15288 organizes system life cycle processes into four groups: Agreement, Organizational Project-Enabling, Technical Management, and Technical processes.
What is the primary difference between a sequential (waterfall) life cycle model and an iterative life cycle model?
Answer: Sequential models complete each phase once before moving to the next; iterative models revisit phases in repeated cycles to refine the system progressively
Sequential models progress through phases linearly, while iterative models revisit phases in repeated cycles, each cycle producing a more refined version of the system.
What is the purpose of the Disposal process in the system life cycle?
Answer: To systematically deactivate, disassemble, and remove a system from operation while managing environmental, safety, and data concerns
The Disposal process systematically deactivates and removes a system from operation, addressing environmental, safety, security, and data sanitization concerns.
In the context of life cycle processes, what does 'tailoring' refer to?
Answer: Adapting standard life cycle processes to fit the specific needs, constraints, and context of a particular project
Tailoring adapts standard life cycle processes to the specific context of a project based on its size, complexity, risk, and domain requirements.
What role does the Maintenance process play after a system enters operational service?
Answer: It sustains system capability through corrective, adaptive, perfective, and preventive actions throughout the operational phase
The Maintenance process sustains system capability through corrective (fixing defects), adaptive (responding to environment changes), perfective (enhancing performance), and preventive (avoiding future problems) actions.
Why is stakeholder involvement throughout the life cycle considered critical rather than optional?
Answer: Continuous stakeholder involvement ensures the evolving system remains aligned with actual needs and enables early detection of misalignment
Continuous stakeholder involvement throughout all life cycle phases ensures the system remains aligned with evolving needs and catches misalignment before it becomes costly to correct.
