- Success factor for implementing Lean: look at the whole supply chain, not only development or test. Think products (end to end) and not only projects.
- Use pull rather than push. Be aware of utilization: an operations manager will react when a servers cpu utilization is getting close to 100% - but what about people utilization …
When implementing Lean it isn’t enough just to use Just-in-time and stop-the-line. It is the people doing the actual work that have the potential to make it a success. They have the good answers and ideas.
All queues and stacks of work is WASTE. Remove the cues, improve the cycle time and get better overall performance and quality. Value stream maps are a powerful tool to identify queues and their size.
Without automatic tests you are asking for trouble. Don’t buy the “we don’t have time to implement automatic tests” excuse, if you wait your problems will grow…
And NO it is not ok to have a backlog that contains work for more than 3 iterations, including ideas for the future – get rid of the WASTE and focus on the important stuff that adds value to the customer.
