The article spends most of its words trying to convince the reader to do it, and only a few paragraphs on how to do it. I was convinced in the first paragraph.
My own experience shows that hiring for your team's weaknesses can make it more effective. In 2013, I went from an operations-heavy role to a new team with little operations experience. Our TL designed and coded a new service. He was not happy with the feedback I gave through the design & code review process. Before deploying the new service to production, we met with one of the company's top engineers (Sanjay Ghemawat) for a "production readiness review". The reviewer was impressed and found only a couple of minor issues. He said that it was rare for him to review a service and find no major issues. Many of the questions he asked during the review were things that I had brought up earlier and convinced our TL to fix. Although I had not written any code on the service, I contributed operational knowledge and filled a weakness of the team.
Our TL did not acknowledge my contribution and even gave me a bad review, costing me about $80k in compensation. Now, years later, I believe that he did that to get me to leave the team. I had often pushed to fix the major problems in our project. I think he wanted to keep control and continue working on fun things and ignore the problems. Our manager went along with him, building his own empire. I left and the person who took my place had the same problem and left as soon as they could. Honesty and respectfulness are important qualities of teams and team members because they develop trust. Trust makes teams more productive. An internal study at Google concluded that teams with members who trust each other are much more productive than teams with high technical ability and low trust [0]. Lack of trust is a team weakness that we can hire to improve. We can also intentionally train and practice skills that improve team trust.
I want a systematic way to identify the strengths and weaknesses of myself, my teammates, and potential teammates. I want a questionnaire like the one in Essential Enneagram which was tested in a study with 1,000 participants [1].
I wish the large tech companies would invest in this kind of work and publish it.
