Software Release Estimate Timeline

Software release estimate timeline

A software release estimate timeline uses three-point estimates to show uncertainty in each major task. Instead of one duration, each activity has an optimistic, likely and pessimistic value. After the build, security review and testing can proceed in parallel, while deployment waits until findings are resolved. This gives a planning conversation more realism than a single date. Update the estimates as evidence improves and use the dependency view to identify the work that controls release timing.

O que há neste desenho

Entenda as decisões por trás dele.

01Estimate uncertainty

Use optimistic, likely and pessimistic values.

02Run reviews in parallel

Security review and testing both follow the build.

03Join findings

Deployment waits for review and test issues to be addressed.

Use when a release estimate needs to show uncertainty and dependency rather than a single fixed duration.

Perguntas frequentes

Dúvidas comuns

What is a three-point estimate?

It records optimistic, most likely and pessimistic duration values for an activity.

Why run testing and security review in parallel?

They are separate activities that can both begin after a completed build.

What should deployment depend on?

It should depend on the resolution of findings from the required review and test work.
