Abstract:
The typical method for project scheduling uses a single time estimate for all tasks. Yet, it is likely that
each task will vary from that singular value as will the planned project completion date. Rather than
using a deterministic date that is inaccurate, it is suggested that a more rigorous model use probabilistic
time estimates that support processes yielding a more desirable answer. This paper will illustrate a
method using variable time estimates associated with a Critical Chain Theory implementation to produce
project schedules that have potential to be finished on schedule and actually shorten traditional cycle
times.
