How deep it goes
Defines hourly estimates, contrasts them with story points, and gives a practical sequence for scoping, breaking down, checking, and revising work.
Examples
Uses fixed-budget projects, consultancy billing, team availability, and an out-of-scope feature addition to illustrate estimation decisions.
What you can do after
Practice/perform hourly estimation by clarifying scope with the team, breaking work into tasks, considering prior work and availability, and revising estimates.

Delivering Machine Learning Projects: From design to deployment

Estimation is the process of forecasting the effort, resources, schedule, or cost needed to deliver a project or its results.

How it is used
Transforms a project hypothesis and delivery context into a resourced, reviewable proposal before customer costs are discussed.
How deep it goes
Specifies work, resourcing, risk premiums, review, documentation, and sign-off without detailing task-level forecasting methods.
Examples
Uses estimate-building tickets, risk registers, mitigation premiums, review meetings, documentation, and accountable budget sign-off.
What you can do after
Apply a structured estimate that exposes resource needs, uncertainty, mitigation costs, and organizational risk before commitment.
