The most effective technique to manage the timeline factor is to track milestones. Effective project planning concentrates on the most critical deliverables, with tasks outlining how the work will be structured to meet the deadlines. Milestones are used to establish these significant delivery dates so that anticipated dates can be compared to committed dates as the project progresses. This is how you keep track of project milestones. Once the plan has been agreed upon with the customer, a baseline or snapshot must be taken to compare the actual project performance. Where comprehensive job assignments are included in the project plans, timesheets are the most significant approach to collect data on the effort expended, and earned value is the most objective indicator of actual performance.
