Denkt an das fünfte Gebot: Schlagt eure Zeit nicht tot. [Remember the fifth commandment, don’t kill time.] —Erich Kästner Recently, it occurred to me how often I try to employ a small set of working principles to stay efficient and on the right track with my work. Furthermore, I noticed how these principles align to what we need in our teams and the whole company to be lean and agile. So, I thought it might be worthwhile to distill it into a compact list. Below, I have listed 13 items at the personal, the team and at the company level that are essential to lean and agile working in my view. In fact, the list reduces to just six items, but adjusted as the context grows.
