Develop Schedule in Project Management is the process of taking all the tasks and activities in a project, estimating them, sequencing them, and creating a timeline for their completion. This includes identifying resources and dependencies, assigning dates, and determining how long each task will take. It also involves managing risk and constraint factors, as well as devising likely scenarios that may affect the project and its timeline. Developing a schedule gives everyone involved in the project a clear understanding of what needs to be done, by when, and who should do it. By establishing realistic expectations, this process can help ensure successful project completion on time and within budget.
