This 59-minute video on Agile Estimating is better sequenced for viewing secondly, following the video on User Stories. Mike Cohn presents:
- estimating size (before) deriving duration (with a range);
- story points as relative effort for a user story in a product backlog;
- ideal time (to complete) as compared to elapsed time (with interruptions);
- “Planning Poker” as an iterative approach to estimating (collaboratively).
The first step in creating a useful plan is the ability to estimate reliably. In this session we will discuss how to do this. We will look at various approaches to estimating including unit-less points and ideal time. The class will present four specific techniques for deriving reliable estimates, including how to use the popular Planning Poker® technique and other techniques that dramatically improve a project’s chances of on-time completion.
