Zen of Scrum: Sprint Planning

By Magnus Nord


Every sprint begins with a planning activity. This is when the Scrum team decides on the work to be done in the iteration ahead.

Sprint planning is divided into two parts.

During the first part user stories are analyzed, evaluated and estimated. After that, the developers determine a reasonable workload that they think they can commit to.

During the second part, selected stories are analyzed in more detail by the developers (remember, I use the term developer for everyone building the product, including coders, designers, testers, documenters, and so on).

Zen of Scrum: When Estimating, Size Matters

By Magnus Nord

yin-yang“Time is what we want most, but what we use worst.” –William Penn.

Never is it more true than when it comes to estimating.

Indeed, to most people estimating effort is tightly coupled to time. How long will it take? When will it be ready?

This is futile: time is a moving target and calendar time, in particular, next to impossible to predict.

A better approach is to estimate the size, or complexity, of work, and to derive duration based on velocity.
