I plan to tackle this using a methodology I learned from Frank E Bird a long time ago. It always works well for me when starting anything I have never done. I will be using a small spreadsheet to break up my thoughts and process into five major steps:
1. Identify the objective and Investigate the situation.
2. Evaluate the options
3. Develop a plan
4. Implement the plan
5. Monitor, measure, and improve
If you do these steps in a loop it becomes the Demming approach of Plan, Do, Check, Adjust (PDCA). Alternately you can replace step 5 with PDCA.
My objective(s) will continue to morph over the initial bit as my starting research unfolds, but once I hit step 3 it is critical to not change the objectives. I have a huge problem with the "Babbage Syndrome' (Les Kilpatrick-1977) and it is crucial that I do a solid lock down before step 4.
