Permanent Link to Feature Flow - Increasing velocity using Kanban - 1 views

  • team that had some problems getting their process right
  • their velocity was decreasing and spirits were low. Luckily we managed to change our process by changing some basic Scrum practices and replacing some of them with Lean practices, inspired by the new Kanban articles and presentations. Productivity is now higher than ever and we can now focus on what really matters: product quality and customer satisfaction.
  • one major issue: getting things done. The major symptom was the frustration of management and the team with the project. The first 3-week time box (sprint) ending with about 30% (!) of all features still in progress, when, of course, they should all have been done and ready for shipment.
  • ...9 more annotations...
  • existing solution to this problem was to lower the expected velocity each sprint, so the next sprint would be on-time. But at the end of next sprint, the same problem occurred, so the velocity was going down sprint after sprint.
  • pressure of the rest of the organisation for the team to keep up their tempo. This pressure from both sides was crushing morale.
  • The way this team reacted to pressure was to work harder. Most people would have 2 or 3 tasks in progress at the same time. When a developer would finish a task, the testers were too busy testing something else, so they could give the developer direct feedback. When the tester found an issue with a new feature, the developers were already working on something else, so the tester had to wait. Simply put, there was too much focus on working long and hard, not on cooperation and the stuff that actually matters: features.
  • most dysfunctional behaviour comes from the system people are in
  • biggest struggle of this team: pressure & predictability.
  • Most Scrum masters challenge the team to reach the same (or higher) velocity each sprint. This pressure should give a team focus to perform at its best. However, it can also go haywire if the team doesn't deliver. No focus, no pride, no happy customer
  • retrospectives were dismal and planning meetings were a huge burden. The teams' productivity dropped in the days after the sprint, finding new courage to start the next one. Because they had an ineffective work-process, the only outcome of each sprint was to lower the expected velocity, to make sure we would be predictable. Estimation and predictability are only a means to an end and since they were getting in the way of fixing the root cause (and were bringing down the team's spirit) I opted to cut out the planning sessions and sprint deadlines.
  • first change we made was to set a limit of 8 tasks on the 'in progress' column
  • We spent 3 weeks bringing the numbers of open tasks from 21 to 8, without picking up any new work. Of course the team struggled with this new limit. They were used to pick up new work whenever they were blocked somehow, this wasn't allowed any more

Managing WIP isn't the same as Limiting WIP: Part 1 - 0 views

  • To determine the truth of this we only need to look at the feature sets of the popular tools for managing eXtreme Programming and Scrum such as Rally, VersionOne, ScrumWorks, Mingle and very new tools like Borland Team Focus, to discover that not a single one of these tools allows you to set an explicit WIP limit. None of them provide a pull signal to start new work. Very few of them are even capable of reporting the quantity of work-in-progress.
  • s we learned more about the value of managing WIP, we introduced concepts to encourage and enable it, such as the use of Cumulative Flow Diagrams (a.k.a. Burn Up charts)
  • Agile teams encountering an impediment would generally mark a story as blocked and go on to another one
  • ...2 more annotations...
  • In a truly WIP limited process impediment removal is paramount.
  • So for those who would claim that Scrum and XP limit WIP and pull new work, such as Stephan Schmidt, I would point them to the feature sets of existing Agile tools. These tools do not impliment WIP limits, pull signalling nor are they particularly good at issue management and resolution. Recently, there are 4 new entrants to the Agile tools market. All of them producing WIP limiting Kanban tools including the same Mr. Schmidt. If earlier Agile methods had been truly WIP limited pull methods then tools from encumbent vendors would already reflect this. As a result there would be no market for new entrants such as CodeMonkeyism, AgileZen, LeanKit and RadTrack. More thoughts on managing WIP versus limiting WIP tomorrow... T
