Journey towards better software development management using lean/kanban flow approaches - especially focused on service delivery in software sustainment. Trying to provide a somewhat fresh view of how to get to kanban thinking, but based on the current recipes (e.g. David Anderson recipe for success)

- 1. The Secret of Flow http://www.flickr.com/photos/yuvalyeret/265568342/in/set-72157594323037021/ The journey towards better software development management using lean/kanban flow approaches Yuval Yeret
- 3. Application maintenance teams are an increasingly important contributor to service delivery and user satisfaction, but they are also a growing component of the IT budget. CIOs will find that paying attention to application maintenance teams delivers good rewards throughlower costs and targeted results Gartner, August 2010 Maintenance == Over 90% of lifetime costs http://users.jyu.fi/~koskinen/smcosts.htm
- 4. Most of maintenance work is managed as projectswe are USED TO manage Projects
- 5. Is there an alternative?
- 7. Enter FLOW based development also called Service Delivery

- 20. Question: What are those Steps?
- 21. quick roundtimefor short trips – no waits More efficient But longer time and queues TIP: Do what MAKeseconomic sense
- 22. A Kanban board – Not a Must for Flow But will SIGNIFICANTLY improve it

- 41. Will visualizing and managing flow in each of those roads be enough?
- 42. Need to visualize and manage the global end to end flow across shared resources
- 43. When dealing with shared resources... we need to apply the flow techniques at the level at which they are shared
- 45. 3 Use Kanban boards to Visualize and manage end to end flow
- 46. How can I take this to my context?
- 47. Add flow charts to your existing work tracking system Something like... HP QualityCenter Microsoft TFS IBM Lotus Notes JIRA Excel...

Notas do Editor
- Over 90% of the cost of software development is software maintenance (cite). This alarming trend was predicted as early as 1972. McKinsey suggests that CIOs should spend no more than 40-60% on maintenance. Gartner’s IT Spending and Demand Survey (2002) reports that CIOs are spending 80% of their budgets on maintenance (p12 of presentation). Agile development can help reverse this trend.

- If our policy/behavior is early start of everything“Working on many things in parallel will ensure high utilization”“Everything is important”“Each engineer has his own baby feature, they don’t want to collaborate, and there is a high collaboration overhead”Batch size is still HIGH
