Q

in the ABL, what is the sublevel physical groupings of the functions in the FBL which are grouped logically?

A

Configuration Items (CI)

22
Q

in what review does the preliminary design ends?

A

Preliminary Design Review (PDR)

23
Q

this uses engineering disciplines to develop the individual subsystems, assemblies, and components in the system

A

Detailed Design and Development

24
Q

Detailed Design and Development results in?

A

Product baseline (PBL)

25
Q

what is the review at the end of the Detailed Design and Development activity?

A

Critical Design Review (CDR)

26
Q

what is the final design review which results in the official acceptance of the design and the subsequent commencement of the construction/production.
PBL CDR?

A

Critical Design Review (CDR)

27
Q

this activity is where components are produced in accordance with the PBL specifications, and the system is ultimately constructed

A

Construction and/or Production

28
Q

Construction and/or Production. activity ends with

A

Formal Qualification Review (FQR)

29
Q

what parties involved defines the system’s requirements, expectations, and constraints based on their needs.

A

customer or end-user

30
Q

what parties involved provides input during the requirement gathering phase, participates in reviews, and gives feedback during testing and validation phases

A

customer or end-user

31
Q

what parties involved oversees the entire project, ensuring that timelines, budgets, and resources are managed effectively

A

project manager

32
Q

what parties involved coordinates between all parties, manages risks, and ensures the project meets its objectives.

A

project manager

33
Q

what parties involved lead the design, integration, and management of complex systems throughout their life cycle

A

systems engineers

34
Q

what parties involved engage in requirements analysis, system design,
integration, verification, validation, and deployment

A

systems engineers

35
Q

what parties involved ensures the system meets the defined requirements and is free of defects.
where they conduct testing at various stages, including unit testing, integration testing, system testing, and acceptance testing

A

test and quality assurance team

35
Q

what parties involved design and build
the system components and work on detailed design, coding, prototyping, and creating technical documentation.

A

Design and Development Team

36
Q

what parties involved integrates various subsystems and components into the final system and ensures compatibility between subsystems and performs integration testing.

A

integration team

37
Q

what parties involved manages the system once it is deployed, including monitoring, maintenance, and updates and engages in deployment, provides support, and ensures system availability and performance

A

operations and maintenance team

38
Q

what parties involved provide hardware, software, or other system components by supplying necessary materials or tools and may also provide technical support and warranties.

A

suppliers and vendors

38
Q

what parties involved ensure that the system complies with relevant laws, regulations, and standards. they review and approve system designs, and conduct audits or inspections.

A

regulatory bodies

38
Q

A linear and sequential approach where each phase (e.g., requirements, design, implementation, testing, deployment) is completed before the next one begins

A

waterfall model

39
Q

what parties involved may provide input during requirements gathering and feedback during testing and validation

A

stakeholders

40
Q

what parties involved manages the decommissioning of the system and are responsible for data migration, archiving, and disposal of system components in compliance with regulation

A

end-of-life team

40
Q

what parties involved include individuals or organizations affected by the system but not directly involved in its development

A

stakeholders

41
Q

an extension of the Waterfall model) where development stages are paired with corresponding testing stages. The
left side of the “V” represents decomposition of requirements, and the right side represents integration and validation.

A

v model

42
Q

is often used in industries where safety, reliability, and regulatory compliance are paramount.

A

v model

43
Q

well-suited for projects where requirements are expected to evolve over time, and where feedback and
refinement are critical to achieving the desired outcomes

A

iterative model

44
Q

It emphasizes developing the system in small, manageable portions (iterations), allowing for continuous improvement and adaptation based on stakeholder feedback

A

iterative model

45
Q
  • emphasizes iterative development,
  • strong focus on risk management and
    flexibility.
  • well-suited for projects that are
    complex, high-risk, and where
    requirements are expected to evolve
    or be refined over time
A

spiral model

46
Q

The process is divided into four phases: planning, risk analysis, engineering, and evaluation, which are repeated in ______

A

spirals
