Developers don’t like to provide time estimates for implementing a software feature. Management, on the other hand, has a legitimate need for project management estimates. This article explains how the Scrum Agile Project Management framework provides a solution to this conflict.
The average Scrum team delivered a 35% improvement in velocity at Yahoo [1] where teams properly coached delivered 300-400% improvements. The best Scrum Master at MySpace peaked at 267% of initial velocity after 12 weeks and averaged 168% increase in velocity over 12 Sprints. Most teams were less successful.
This article discusses estimation techniques for teams that are adopting Scrum. The authors recommend to use story points during the release planning phase, but initially to switch to hours to estimate tasks during the sprint planning. Then the team will gradually move to using story points to estimate complete stories that members will commit for in next sprint.
Thom Roach shares with us in this blog post the metrics that he includes in iteration summary reports. The three main statistics he uses are Iteration Statistics summary, Iteration Cumulative Flow and Team Velocity Chart.
This short presentation explains why software metrics are not the panacea that we thought they might be 20 years ago. This is why moving from a predictive model to a reactive approach is the only rational course.
Mike Cohn wrote an interesting post where he discusses he allows or even encourages to estimate with story points as large as 20, 40, and 100. He explains that they are useful when you need first and not necessarily precise estimate of the general size of a new project being considered.
How do you know if you are developing and maturing as a team? How do you know you are getting good at this agile stuff? Typically agile talks about the soft side of things with a focus on the less tangible aspects such as individuals and interactions. Are there things that teams can tangibly work towards and measure their progress against? This video presents metrics that will help you assess the agile maturity of your team.
