Milestones in project planning are defined as a set of key results that have to be achieved within a predetermined time frame in order to ensure successful completion of a project. Milestones serve as checkpoints to measure progress and ensure that deadlines are met while also managing resources efficiently. They help to keep projects on track and within budget, while providing the necessary motivation to complete goals and objectives. When used strategically they can give clear visibility into the status of the project, allow for more accurate forecasts and more effective decision making. Milestones provide clarity and focus to bring success to projects!
