I hate outsourcing IT development

Hello everyone! I recently asked here about whether there is an alternative to outsourcing. In general, I once had such a situation when I gave the task to an outsourcing company to make a Healthcare product and, if possible, if my thoughts about the idea and features of the product were wrong, correct everything, but discuss it with me beforehand. But in fact, despite the fact that there was communication with the outsourcing team and they performed the technical part well, I still got something that was good six months ago. Yes, the deadlines were met, but the competitors did not sleep and the crowded market got new features, which I did not think about and which I could not react to quickly due to poor experience specifically in Healthcare. Moreover, the outsourcing team did not even take into account the legislative framework for working with the deletion of patient data, which needs to be adapted in the application. Therefore, the work was only delayed in terms. And in this case, the question arises: why do you need IT outsourcing if the team that received high marks on Clutch can't even help you get through what you don't know yourself. There is no time to study, because investors are pushing. Therefore, I put all this on the shoulders of another team that has developed dozens of projects before. But unfortunately, my experience and the experience of some of my colleagues suggest that IT outsourcing is just performers who need a manager who understands a particular area in detail. Because it is impossible to take everything into account if you turn to someone who works in several fields at once. That is why, by the way, the outstaffing proposed in my last question also goes by. Are these problems familiar to you and how did you deal with them?
