Understand the what, when and why of the project and its due dates. This involves clear communication, and results in a realistic schedule that should satisfy the requirements of the client and your team’s ability to deliver it.
Restricted access to project information, documents and data can cause a significant increase in project cost and schedule. Ensure all your project team has access to the information and data they need.
Specify the due date of project deliverables. This will give clear expectations that lead to less confusion, and a higher likelihood that your project will be delivered on time, on budget and to the satisfaction of the client.
Projects are complicated. Lots of agreements and changes are constantly made, these should be managed properly.
Document all changes, variations and agreements on your projects. You should put everything in writing.
