This is Profit Savvy's equivalent of Godzilla meets the Hulk! In our language it is the mixing of the 80/20 Rule, which promises up to 16x growth and the TOC approach, which describes the most liberating aspect of your production line.
The Theory of Constraints (TOC) points out that there is generally only one part of your production cycle that limits the throughput of your production cycle. Anything upstream or downstream of that "choke point" or "constraint" is able to produce more than can get through the constraint. Therefore, the main place to focus is the constraint.
See the Theory of Constraints (TOC) for more on how to identify the constraint and take advantage of it.
The 80/20 Principle argues that 20% of what you do leads to 80% of the outcomes. For an introduction to 80/20 see The Amazing 80/20 Rule Tool and for a group of articles applying 80/20 to many aspects of business, see 80/20 Rule Menu
80/20 meets TOC
It is easy to see that the very powerful 80/20 Rule and TOC are closely related.
It is easy to see that 20% of a production line of any type might be the "constraint" that is the centrepiece of TOC.
Both theories would argue that liberating the constraint would have the maximum impact on your productivity.
