By popular request (thanks Francis!) I’m going to get a bit more rigorous about noting books I’ve read. You’ll then be able to find them in a consistent place: https://mmitii.mattballantine.com/category/bookshelf/
Richard Rumelt’s Good Strategy/Bad Strategy is a very readable exploration of what the author believes makes the difference between good and bad strategy. He’s obviously been in a number of significant discussions in many big organisations over the years from the anecdotes that litter the text. Solid thinking, in my opinion.
The Power of Habit by Charles Duhigg looks at the psychology and sociology of how habits work in individuals, organisations, and societies, and how you can go about changing them. Good practical advice in fostering change in the first two of those.
