Managing the Client: A Fairy Tale
Remember that a successful project has a measurable and positive impact on the client's business objectives. Set a time period to measure the progress toward achieving those objectives, and plan to measure progress on a regular basis. If you find that there are adjustments that should be made, or additions that can improve the project's functionality, do them.
