You can overcome resistance to tracking by explaining your expectations, explaining the benefits of tracking, and training people to track the task themselves.

Resistance to formal tracking of project management data is normal. A Project Manager should not assume that everything is progressing according to plan and should always keep track of each task.

Once your project plan is ready in MS Project, it becomes essential for a project manager to measure the actuals (in terms of work completed, resources used and costs incurred) and to revise and change information about tasks and resources due to any changes to the plans.
