Focus may be about saying no to good ideas, but it certainly doesn't mean doing one thing at a time. This is what focus looks like at an organisational level, seen through the lens of business and war.
@cedric Business is not war, but like war, business is complex. That, as you’ve noted, makes the development of expertise challenging. Getting the most out of feedback is imperative. Warfighting notes,
Because we recognize that no two situations in war are the same, our critiques should focus not so much on the actions we took as on why we took those actions and why they brought the results they did. (emphasis added)
Too often in business, we fail to understand causation beyond that which is readily observable in space and time.
