ABSTRACT
The project control system must provide timely information on both progress and costs in a form that is meaningful and can be related directly to the project baseline position. The slip diagram can be a powerful tool for assessing the progress of the whole project and predicting the final position. A basic network should be constructed using the work packages or major tasks to lay out the main logic and establish overall timescales. The major tasks, themselves, will be too large and general for both precise logic definition and project control; hence they must be broken down into minor tasks or activities. Network can be updated with progress directly from the data generated by the time-bookings and accounting systems as the codes in both systems are identical. The cost-performance measurement terminology that has come to be accepted is based on the US DoD Cost/Schedule Control Systems Criteria.
