1. PREDICTABLE - Ensuring that the outcome is consistent.  For example installing a light fixture is (1) done correctly the first time; each time and (2) that the time it takes for each unit is approximately the same each time - for example 1 hour each.  
2. PRODUCTIVE - Continuously improving the cycle time getting it down to 30 minutes each.  Then continuing to improve down to 20 minutes each; then 15. A core element of PDCA is that there must be a predictable standard in place before you start your cycle of process improvements. 
3. SCALABLE - Developing the additional people to be able to replicate the productivity and developing the additional business based on that operational excellence that will use that additional talent.  You won’t have a sustainable growth model if you don’t focus on both the talent and business development aggressively. You can’t focus on this until you have a predictable and productive system in place that truly adds value to the customer.  

Consider how this relates to the two key results of a great project planning process. 

Consider how this relates to the Last Planner System on a project.

What process have you tried to make productive or scale before you have made it predictable?
