This chapter covers the following topics:
• agile estimation approaches;
• why and when to estimate;
• estimation techniques.
Accurate estimation is essential to all types of change projects, but the Just Enough, Just in Time concept presents new challenges for business analysts working alongside or within agile teams. When the detail of project scope is not known up front, how can the team provide useful estimates?
This chapter introduces the key principles that underpin most agile estimation techniques, and puts them into context. Examples demonstrate how agile teams use estimation in practice and highlight how these techniques can be utilised effectively by business analysts.
