I agree the post is great (which is why I submitted it) but I also found the last couple of paragraphs kind of a let down, after nodding along enthusiastically for the rest of the article.

The article links to this other post on a similar topic https://www.sicpers.info/2021/03/one-person-per-task/. The advice there boils down to "hey, remember agile? Not just the 'use Jira' but, but the rest of it. That was a good idea!"
