Manage a Complex Test Effort with Lean and Kanban

TechWell

“How absurd! She swallowed a bird. She swallowed the bird to catch the spider. She swallowed the spider to catch the fly. I don't know why she swallowed the fly. Perhaps she'll die.” The silly nursery rhyme teaches a serious lesson. Because software products are complex, we seek to manage them by spinning a complex web of processes and tools. Thankfully, not all complex problems demand complex solutions. Join Mike Duskis as he demonstrates how his test team employed kanban practices to manage the test work of a multi-national, multi-project department with a system of index cards on the wall. With the kanban system in place and lean practices driving decisions, the team simplified the prioritization process, improved test visibility, which led to better testing choices. Lean-kanban produced strong results at Mike's shop and could do the same for yours. Join Mike to learn how you can clarify and communicate your test effort—without swallowing any spiders.
