The XY problem is focusing on the attempted solution rather than the problem. This leads to resource waste. - Mr. A wants to do X. - Mr. A doesn't know how to do X, but thinks he can come closer to doing X if he can do Y. - Mr. A doesn't know how to do Y either. - Mr. A asks Mr. B for help on Y - Scenario 1: Mr. B is unable to solve Y. Resources are wasted. - Scenario 2: Mr. B is able to solve Y, but it is discovered that solving Y does not contribute to solving X. Resources are wasted.
