In any management endeavor, time is a precious commodity. It is so valuable that it is only wise to use it with respect.
Individuals and organizations can plan all they want but the schedule becomes the focal point comes execution. It is impossible to accomplish all activities on time if the schedule is poorly developed. While a bad schedule will most likely fail, a good schedule will succeed. The quality of the schedule translates easily to the end quality and cost of the project. A project manager is foolish to expect a timely delivery of a bad schedule. A bad schedule will result in budget overruns, and poor quality facilities, products/services. A poorly prepared schedule will not stay to expectation. Enhancing success is possible by creating a P50 Risk-based, sound, and achievable baseline schedule.
