The entire idea of "can do vs can't do" is such a platitude anyways, it's not even remotely interesting. It takes all nuance away from communication. As if just because someone has to make their position clearer than a statement like "yes, if" in order to manage the expectations of others that they just don't have a "can do" attitude and by implication are destined to fail.
I think the entire point is that they say the same thing while projecting a completely different attitude.
The way that someone responds to the question of "can we do this" is very important.
Cynics always have scapegoats. It's always everyone else's fault. Dumb colleagues, idiotic managers, stupid customers. Just remember you control your situation and how those around you interact with you.
The 'Yes, if' thing is one of the major reasons I love startups.
We typically call this middle management.
Regardless I'm not really interested in the blame game on who's responsible management or engineering. Both are irrelevant to this discussion. "Can" or "can't", as the article discusses, is an issue of leadership in a business. If it isn't there, it isn't going to matter whether the engineer says "how high?" whenever their asked to jump.
The only thing that could top your comment is mine; now we're two meta levels deep, not even discussing the original article anymore.
I prefer "yes, if" but reality says that the "ifs" will never be made part of the planning and then blame will come back to you because you said "yes"
I find it similar to the "estimates" of when we'll finish something, that get turned into hard delivery deadlines once the project scribe commits them to the first draft of the project plan.
In an article about Can Do vs Can't Do culture, it piggybacks on an insightful top comment that takes an optimistic approach and provides the kind of cynical pessimism and tries to shoot down the Can Do nature of the OP's comment. But the best part of it, the most beautiful part, is that it places the blame on the cause of all problems for hackers: the manager. Literally, managers are the only reason the world isn't amazing, they're the ones that shoot down all my brilliant ideas.
