Software Release PERT Estimate

Software release three-point PERT

This PERT estimate uses optimistic, most likely and pessimistic durations for a software release. Planning releases feature development and documentation, while testing follows the feature build. Approval waits for both tested software and updated documentation before deployment. The three-point values let a delivery team discuss uncertainty instead of pretending every task has a fixed duration. It is a compact model for planning a release window, identifying the longest expected sequence and testing how a delayed build affects the likely launch date. Add review, change-control or monitoring work when it constrains the actual release.
