INCOSE ASEP Chapter 3 Flashcards
What are the 3 aspects that every life cycle consists of?
- Business (business case)
- Budget (funding)
- Technical (product)
What is a decision gate?
An approval event in the project cycle, sufficiently important to be defined and included in the schedule by the project manager, executive management, or the customer.
All decision gates are a review and milestone
What are the 2 minimum decision gates?
Authority to proceed and final acceptance of the project deliverable
What are the 6 generic life cycle stages?
- Concept
- Development
- Production
- Utilization
- Support
- Retirement
How does the Concept life cycle stage begin?
With some recognition of a need for new or modified SOI.
Define - Development stage
Defines and realizes a SOI that meets its stakeholder requirements and can be produced, utilized, supported and retired. Input is from the Concept stage and output is a realized system.
Define - Production stage
Where the system is produced or manufactured.
Define - Utilization stage
Where the system is operated in its intended environment to deliver its intended services.
Define - Support stage
The system is provided services that enable continued operation.
Define - Retirement stage
The system and its related services are removed from operation. Planning for retirement should start in the concept stage.
Define - Iteration
The repeated application of and interaction between two or more processes at the same level in the system structure or hierarchy.
Define - Recursion
The repeated application of and interaction of processes at successive levels in the system structure.
What are the strengths of using a sequential LCM method?
Predictability, stability, repeatability, and high assurance
What does the Vee model highlight/prioritize?
It highlights the need for continuous validation with the stakeholders, defining verification plans during requirements development, and continuous risk/opportunity assessment.
What is verification?
Proving that the system is built right
What is validation?
Proving that the right system was built.
What does IID stand for?
Incremental and iterative development method
When is the IID approach used?
When the requirements are unclear from the beginning or the stakeholder wishes to hold the SOI open to possible new technology.
What type of systems are best for IID methods?
Smaller, less complex systems or system elements.
What does ICSM stand for? How/when is it used?
Incremental Commitment Spiral Model. Each increment addresses requirements and solutions concurrently, rather than sequentially.
What does Conway’s law suggest?
Organizations which design systems… are constrained to produce designs which are copies of the communication structures of those organizations.
What are 3 simple criteria to avoid the pitfall of Conway’s Law?
Facilitate communications, streamline controls, simplify paperwork
What are the 3 project business case issues?
Market demand, affordability, realistic schedules
What is the goal of IID methods?
Rapid value and responsiveness
The key mechanism for delivering the direction component of velocity in IID methods.
Incorporation of stakeholders into working-level teams
What purpose do modifications during the Utilization stage do to the system?
Enhance the capabilities of the system
What purpose do modifications during the support stage do the system?
Resolve supportability problems, reduce operational costs, extend the life of the system
