Could use opinions on another example of the topic keeping SCRAP focused and thin as possible without losing something essential. Improvement. Currently, the book provides a VERY minimal improvement loop in case the reader doesn’t have/do such a thing.
For those that already have such a thing, or even a strong opinion, I want them to think about it as an interface they can use their existing improvement approach to fill. This way we don’t get distracted by model debates- if you have an opinion about how to do iterative continuous improvement, and it does some minimal things, use yours! SCRAP slides right in… Here is some language.
SCRAP provides a minimal improvement loop. You don’t need to use it. If you already have an improvement approach that works for you, use yours—but it must provide the essential functions of identifying what to improve, designing how you’ll intervene and evaluate the result, acting, and learning from what happens.
Those four functions become something close to an interface contract:
Determine what needs to change or improve and why.
Decide what you will do and how you will learn from it: the intervention or experiment, expected outcome or hypothesis, and means of evaluating what happens.
Carry out the change sufficiently to generate meaningful evidence.
Evaluate what happened and what it means, including whether the results challenge not only the intervention but the assumptions, goals, or reasoning behind it; then use that learning to inform what happens next.
Use ours or use yours. What matters isn’t the name of the improvement approach, but whether it does the necessary work.
PDCA, DMAIC, OODA, Build-Measure-Learn, Lean Kata—or something of your own design—are all approaches that SCRAP can fit in to. But adopting the name of an improvement approach doesn’t guarantee that you’ve implemented the capabilities SCRAP requires.
Thoughts/comments/concerns? Again, this is about the book, not necessarily other works that may be produced.
@TLooy @Richard @SeanWBuck this is an area of special experience for y’all so any comments would be awesome.
