A milestone is a marker of progress in a project, something to measure progress against and celebrate when achieved. It gives the team a clear target or flag to aim for throughout the project. When thoughtfully planned, milestones are realistic markers of progress that help build confidence in achieving the end goal while also providing an indication of how work progresses on the way to completion. Additionally, by having these markers of progress laid out early on, it’s easier to identify any areas where performance isn’t meeting expectations before it becomes too late. Setting milestones for ongoing projects is essential for staying organized and ensuring success.
