The Waterfall methodology is a linear approach where requirements are defined upfront, and changes are difficult to accommodate once the project begins. Agile methodology , on the other hand, emphasizes flexibility and adaptability to changing requirements.
Key Considerations:
Inherent Uncertainty in Cost: While cost uncertainty exists in both methodologies, Agile does not specifically address this drawback of Waterfall.
Inflexibility to Changing Requirements: Waterfall's rigid structure makes it difficult to incorporate changes once the project starts. Agile addresses this by allowing iterative development and continuous feedback.
Capturing All Requirements Upfront: Agile does not aim to capture all requirements upfront; instead, it embraces evolving requirements throughout the project.
Stakeholder Agreement on Scope Before Work Begins: Agile encourages ongoing collaboration with stakeholders rather than requiring scope agreement upfront.
Evaluation of Each Option:
A. The agile methodology addresses the inherent uncertainty in cost associated with waterfall:Agile does not specifically address cost uncertainty.Conclusion: This is not correct .
B. Agile development addresses the inflexibility of waterfall as it pertains to changing requirements:This is the primary drawback of Waterfall that Agile addresses through its iterative and flexible approach.Conclusion: This is correct .
C. The agile methodology captures all requirements at the start of a project to reduce risks typically experienced in waterfall:Agile does not capture all requirements upfront; it embraces evolving requirements.Conclusion: This is not correct .
D. Agile development requires stakeholders to agree to the scope of the project before the work begins, reducing uncertainty in the design:Agile does not require upfront scope agreement; it promotes adaptive planning.Conclusion: This is not correct .
Final Recommendation:
The drawback of Waterfall addressed in Agile is:
B. Agile development addresses the inflexibility of waterfall as it pertains to changing requirements.
