From the Leningrad TRIZ school's function analysis and trimming, credited chiefly to Simon S. Litvin, and set out by Darrell Mann (Hands-On Systematic Innovation, 2002).
Removes a component from a product, process, or organization by handing its function to something already present, cutting cost and complexity while keeping the function.
When to reach for it
Costs must come down in a design, process, or structure that carries too many parts or steps, without losing what the system does.
How it runs
- Map each component and the function it performs.
- Ask whether another component or outside resource could do that function.
- Reassign the function where one can.
- Remove the component that is now redundant.
- Confirm the function still works, then look for the next trim.
