Lean

Definition

Lean: Value, waste removal, flow, pull, standard work, visual management, and respect for people.

History

Lean sits in the improvement-methodology tradition: structured ways to frame problems, sequence work, coordinate teams, and turn improvement intent into repeatable practice.

When to Use

Use Lean when a team needs an organized improvement approach, clear project cadence, defined roles, and a practical sequence for moving from problem to result.

Step-by-Step

• Clarify why Lean is the right methodology for the problem type.
• Define scope, owner, expected output, cadence, and decision checkpoints.
• Apply the method through the appropriate phases, events, or routines.
• Verify results, document learning, and transfer ownership into daily management.

Examples

• Apply Lean to a real process, project, role, or learning path where the entry can guide a decision.
• Connect the entry to at least one guide, tool, template, case study, or implementation review before treating it as complete.

Common Pitfalls

• Using Lean as terminology only, without connecting it to behavior, evidence, or process results.
• Skipping operational definitions, ownership, context, or follow-up when applying the entry.
• Forcing the entry into a situation where another BoK method or reference would fit better.
