Many years ago, I was on a working group looking at different ways to improve quality within a fairly large software development company. One of the most useful ideas the consultants brought to the table was that we should have “technical reviews” at key stages in the development process. The arguments back then were much the same as they are today: identify potential problems the original developer missed, share interesting ideas in time to consider and use them, making changes earlier is usually easier and cheaper, etc.

Today code reviews have become common practice, which is definitely a change for the better, but I rarely see assets like specs or design work reviewed with the same consistency and attention to detail. If anything, the trend has been to minimise formal requirements capture and to reduce or eliminate any kind of up-front design work, as if there is some kind of bizarre dichotomy where the only amounts of time you can invest in these activities before starting to write code are measured in either months or minutes. I believe this is a mistake that often leads to avoidable wasted work and tech debt.
