when it comes to some diets, some only work if you follow them wholeheartedly, like meat only diet, one speck of peppar might be enough to cause an inflammation. But generally you can't take a process that worked well for another person or company and apply it on you or your company. Like for example a training program, you can't just take a training program from a professional athlete and reuse it on your kid and expect him/her to become as good as the pro. Programs and processes are very individual tailored.
