Lean tools

Below are key tools used to improve processes through Lean.

Value Stream Mapping
Kaizen
8-Step Problem Solving Model

Value Stream Mapping (VSM)

Value stream mapping refers to the activity of developing a high‐level visual representation of the process flow involved in delivering a product or service (a "value stream") to customers. VSM events focus on identifying sources of non‐value added activity (waste) and prioritizing future improvement activities.

Kaizen Events

Kaizen means "to change for the good of all." Kaizen activity is often focused in rapid process improvement events (kaizen events) that bring together a cross‐functional team for 2‐5 days to study a specific process and immediately implement process changes.

  • See Examples page for more information on the use of Kaizen in state agencies.

8-Step Problem Solving Model

Refined over the years by Toyota, the 8-Step model creates a common language and framework for problem solving. The tool enables teams to develop a common understanding of a problem, its causes, and what countermeasures to implement to solve it. Research shows a team's chances of implementing successful solutions goes up significantly by using this approach. It also helps teams build consensus on the best way to resolve a problem.
