When a customer requires additions to the project scope despite additional time and money, which approach is most suitable for managing these changes?

When a customer requests additions to the project scope, especially when they are also willing to invest additional time and money, adopting an Agile approach is particularly suitable for managing these changes. Agile methodologies are designed to accommodate evolving requirements and focus on iterative development. This means that project teams can work in short cycles, or sprints, allowing them to deliver increments of the project progressively and gather feedback throughout the development process.

This flexibility enables teams to adapt to changing requirements, incorporate new features, and make adjustments based on customer feedback without significant disruption to the overall project timeline. The Agile framework encourages collaboration with stakeholders, ensuring that their changing needs and expectations can be met without abandoning the entire project plan.

In contrast, a traditional waterfall approach typically follows a linear process where each phase must be completed before moving on to the next. This rigidity can make it difficult to incorporate changes without significant rework and potential delays, which does not align with the customer's desire to add features without impacting project delivery negatively. Therefore, choosing an Agile approach allows for a more responsive and adaptive project management style that is well-suited to dealing with scope changes efficiently.
