Lesson 2 Choosing the right methodology
- Large and complex projects may benefit from the Spiral model due to its focus on
risk management and iterative development.
- Smaller, less complex projects might be better suited to Waterfall or RAD,
depending on the need for speed and flexibility.
PROJECT SIZE AND COMPLEXITY
- If requirements are stable and well-understood, Waterfall may be appropriate.
- For projects with evolving or unclear requirements, Agile or RAD might be more
suitable.
REQUIREMENTS STABILITY
-Projects with high risks, such as new technology or complex integrations, may benefit from the Spiral model due to its emphasis on risk assessment.
- Lower-risk projects may proceed well with Agile or RAD.
RISK FACTORS
- If users are highly involved and their feedback is crucial, Agile or RAD are preferable as they allow for continuous user engagement.
- Waterfall is less suitable for projects where user feedback is expected to change the
direction of the development.
USER INVOLVEMENT
- When time-to-market is critical, RAD may be the best choice due to its rapid
development process.
- Agile also allows for quicker releases but within a more structured iterative process.
