The challenge is finding out what the variables may be that is causing the unwanted outcomes. Change is the remedy or the culprit. Many times the solution with a change agent may not be the right answer. But, you can always go back to the drawing board. From every solution that doesn't work you can draw more information to create your next step to the workable outcomes. It takes time to fine tune change for solutions into the best possible outcomes. The secret to fine tuning is not to give up when you are getting close and you don't always know when you are close. Persistence is the best solution to getting to the outcome goal.
