Have a preliminary, high-level, plan of operations.
Does not inlude:
Group Operations by location constraint
1.1. None
1.2. Switerland
1.3. Paddoc
1.4. Launch Site
1.5. Launch Pad
String all of your blocks together
2.1. Start at the last operation (launch) and move back in time to the first operations in switzerland using the dependancies which you defined.
2.2. Try and "parallelise" as many blocks as possible (what two operation blocks could be done at the same time if we had enough operators)
2.3. Try and perform all of your blocks as early as possible.
