Why does my firmware need … honesty?

There are some things that have been believed for so long, and so universally, we don’t think to question them. Mostly, this makes sense: we believe them because they’re right. But it isn’t true in every case.

The waterfall method of design is an infamous example. It took a carefully-applied dose ofย doublethink to do what actually worked, while still believing that waterfall was correct. We weren’t deliberately lying to ourselves or each other; we didn’t (consciously) realise what we were doing. And this is the sort of (dis)honesty I’m referring to. Intentional deception is very rare in firmware design, in my experience.

I think I may have spotted something of this kind. Let’s see if you agree. ๐Ÿ™‚ Many commentators publish articles and books containing good and wise advice. [No irony intended: their advice is good and wise, as far as I can tell.] But they often seem to assume that we (designers) are all good (enough) at what we do, and that we want to get better at it. There are many working developers who do not meet these criteria. This matters because the advice often depends for its goodness and wisdom on its recipients (us) being both able and willing to take its recommendations on board.

Ego-less code reviews, for example, are often recommended, and with good reason. But some of us can only manage this some of the time, and some of us can’t do it at all. We’re human! We exhibit human failings. So ego-assassination code reviews are more common than we would prefer, with all the negative consequences we might expect. [Better not to review at all than this?]

I’m not attacking humans. What would be the point? ๐Ÿ˜‰ But I do think the design practices we create and recommend should be suitable for real designers, not just for Vulcans or androids. I think there’s a point in that, and I think it may be one of those things we’ve accidentally ignored for too long. What do you think? Do I have a point? Are there other things we ignore, that we should look at more carefully and more critically? How about leaving a comment? ๐Ÿ˜‰
