- Project (flexible flow), such as construction and product development
- Job (jumbled flow), such as a tooling or a car repair shop

The following matrix shows an overview of manufacturing processes, organized by variety and volume. As a rule of thumb, use the Lean Factory Audit (LFA) for all businesses that process physical goods – adding value to items that can be touched, moved, and stored.
Scores from the questionnaires are best graphed using a radar chart. Five concentric circles represent the five maturity levels, crossed by twenty lines, one for every assessment key. The audit chart is generated with the following steps:
- Download and print the audit template,
- Enter scores of individual keys and calculate the average score,
- Transfer scores to the radar chart, one dot per key,
- Connect dots to draw the profile, and
- Add reference information, such as assessment scope and date.
