Final answer:
The Waterfall methodology provides distinct milestones for change and each phase must be completed before moving on to the next, making it the right answer.
Step-by-step explanation:
The methodology that provides milestones that must be achieved for successful change to occur is the Waterfall methodology. The Waterfall methodology is a linear and sequential approach to project management and software development. It is characterized by a series of phases that flow logically from one to the next, just like a waterfall. Each phase must be completed before the next phase can begin, providing clear milestones and deliverables at each stage. This approach contrasts with Agile and Scrum methodologies, which are iterative and enable changes to be made at any stage of the development process. The Lean methodology is more focused on eliminating waste and increasing efficiency rather than setting specific milestones.
When establishing criteria to measure progress, questions such as "How will I know when it is accomplished?" are crucial. The criteria should be both measurable and motivational to ensure that progress towards the achievement of goals can be tracked and that the team is encouraged to reach the milestones.
