Question

Explain the functionality of the quadrant approach in the Spiral Model.answer for 5marks

Answer 1

Spiral model has four quadrants.

Quadrant 1 - Determine objectives, alternatives and constraints:

• Objectives − Functionality, performance, hardware/software interface, critical success factors, etc.
• Alternatives − Build, reuse, buy, sub-contract, etc.
• Constraints − Cost, schedule, interface, etc.

Quadrant 2 - Evaluate alternatives, identify and resolve risks:

• Study alternatives relative to the objectives and constraints that are determined.
• Identify risks such as lack of experience, new technology, tight schedules, etc.
• Resolve the identified risks evaluating their impact on the project, identifying the needed mitigation and contingency plans and implementing them. Risks always need to be monitored.

Quadrant 3 - Develop next-level product:

Typical activities include −

• Create a design
• Review design
• Develop code
• Inspect code
• Test product

Quadrant 4 - Plan next phase:

Typical activities include −

• Develop project plan
• Develop configuration management plan
• Develop a test plan
• Develop an installation plan
