I was asked recently, “If what I am doing is working, do I really need to know how and why?” I could see why this question was being asked. After all, if we start worrying about the how and why of all the problems we solve, our output would decline, and our nerves would be frazzled. I believe the expression for this is “analysis paralysis.”
Here is a guideline I proposed to break the deadlock. If the problem relates to your core competence, and is critical for your success, and something you use in your point of performance, then you need to know the how and why. For exceptions, see next para.
There is a further clarification, if no one has understood the how and why, then it is a research project. Don’t proceed unless you have funding or time and money to burn. But if at least one other person has understood the how and why, then it is a best practice, you would do well to reach out to learn more.
