I keep seeing people say that “estimation doesn’t work for software development.” I don’t see them saying what “work” means. I think they have unrealistic expectations, and/or an inappropriate approach to estimation. 1/6 One common assumption for “work” seems to be “perfectly predicts the future” with both accuracy and precision. I know of nothing and no one who can do that. And if you could do that, what benefit do you expect? 2/6

It's disheartening to me how many want to blame the struggles of large-scale Agile transformations on management. Which invites management to blame the dev teams for not playing along. And in reality, both sides want to get to a better place. It's not surprising that a management team trying to shift to Agile uses a lot of the top-down tactics and strategies that got them their current success. Of course they want to push changes that could, according to what they read, save or enhance the company's future.

As a white man in western society, I have privilege. I didn't ask for this privilege. I did nothing to earn it. Yet there it is, merely because I'm a white man in western society. 1/6 That privilege accorded me for being a white man in western society allows me opportunities that others might not have. It offers me considerations that get me "off the hook" for minor transgressions. It treats me with less suspicion in many circumstances. 2/6

Something that's been bothering me a lot recently, in a lot of different contexts, is the rush to judgement of people. Must we divide people into Good and Bad? Can that possibly be true? Think of the best person you know. Is there nothing that they do, or have ever done, that you consider Bad? Do you excuse or overlook that behavior because you know that they're a great person overall?
