Develop credible proposal schedule durations by estimating each activity from defined scope, realistic resources, applicable calendars, historical performance and known external dependencies. Then document the basis for each material estimate
A schedule basis of estimate explains why an activity has its planned duration. It records the scope, estimating method, historical basis, resource assumptions, calendars, constraints and risks that support the
A three point schedule estimate uses optimistic, most likely and pessimistic durations to describe the uncertainty surrounding an activity. The scheduler can convert those inputs into a weighted duration for
