I keep reading that quality needs to take a back seat to profit, but I'm beginning to think that the people who say that don't define "quality" the same way I do.
Let's take "well architected" as an example.

No metric improves product decisions. You do that by talking to your customers.
What does improve product decisions is empathy, feedback, and understanding the market.

@attikusfinch.bsky.social If you're buying it, you don't need an estimate. You know the cost. If you're building it from scratch, then there's innovation involved. Otherwise, why bother to build it? Not much point in building something you can buy.

Work with agility. Build the smallest core of the core of the core idea to test the market. If that's accepted, use feedback to determine what to build next. Work small, release frequently, get feedback, adjust. Works well.

It's literally impossible for them to be accurate when you also need to build the most valuable software, because we learn as we work, and every scope change changes the estimate. Also, many of the things we do cannot be estimated because they involve discovery.

Demanding an estimate guarantees the estimate will not be useful to the business and will always drive costs up.
Software engineers all know that estimates are useless.

The idea of getting a "project funded" is flawed. Work on the product as a whole. Move teams to the most critical work as needed. Of course, any organization that believes what you do will not be open to innovation, so there's little point in bringing this up.

After expanding a vdev or changing compression settings, existing data won’t automatically rebalance.
A ZFS rewrite lets you update selected files in place—applying new allocation and compression properties without moving data off the system.

There is no up-front plan, though there is an objective (solve the problem). There are no fixed acceptance criteria. There are no tickets. There is no schedule (though you work as small as possible, so "within a couple of days" will do).

3) Start.
4) As you're working, get feedback ("Hey Fred, come over and take a look at this!"). If necessary, adjust what you're building based on that feedback.
