Where to start

Answer:
When you start reading about the topic quality, in general, you will most likely find the PDCA cycle, something that stands for

According to this cycle, we start by planning our objective and then work towards attaining it.

After years of using this approach, I found a better one, less known, developed by a Japanese, something like this:

We start in the Control Cycle. We have a standard (written or not), we work according to the standard, we check the results and we act, we decide what to do. If performance is OK we continue within the Control Cycle. If performance is not OK, or if we wa nt to improve current performance, our decision is to leave the Control Cycle and join the Improvement Cycle. We start with the problem, or challenge at hand, we plan a way to solve it or meet the target, we try an experiment (DO), we check the results, if the results are not OK our action, our decision is to plan another experiment. If the results are OK, our action is to set the experimental conditions as our new standard and we are back to the control cycle.

So, I would recommend to first define clearly your problem, why it is a problem, and what will be the success criteria for that problem.
