Do not assume every input contributes equally.
Leverage field guide
The 80/20 Principle
A practical interpretation of Richard Koch's idea that a minority of inputs often produces a majority of results. Find the imbalance, protect the vital few, and simplify the rest.
Trace totals back to their sources.
Move resources toward what already works.
Eliminate, automate, delegate, or simplify.
The asymmetry mindset
Small causes can create large effects.
Use evidence to discover where value concentrates in work and life.
Choose one result
Revenue, learning, joy, leads, quality, or time saved.
Break apart the total
List customers, channels, tasks, products, or causes.
Sort by contribution
Make the uneven pattern visible.
Study the winners
Find repeatable traits behind top contributors.
Reduce complexity
Low-value work often taxes the whole system.
Repeat the analysis
The vital few change as conditions evolve.
Pareto analysis
From busyness to a ranked map.
Define one outcome
Use a meaningful measure and fixed period.
List every source
Use comparable categories.
Rank the sources
Calculate each contribution and cumulative value.
Explain the top few
Look for common causes you can reproduce.
Reallocate
Expand, test, simplify, delegate, or stop.
Your leverage canvas
Identify the few that matter most.
