A3 Thinking Used to Support Strategy Deployment in Munters


A3 Thinking Used to Support Strategy Deployment in Munters

During its lean transformation Munters, a global leader in energy efficient air treatment solutions, underwent a strategy deployment exercise. They needed a way to consistently, simply and quickly capture and communicate policies (vision, mission, goals) between different levels. They found the answer in an A3 Thinking.

A3 thinking is primarily a problem-solving approach that uses a single standard A3 format sheet of paper to guide, capture and communicate a problem-solving process. However, the idea of having a single A3 sheet with predefined template is transversal, and A3 is often used as a reporting medium.

Munters is one of the world’s leading suppliers of air treatment solutions. The company was founded in 1955 and has since expanded from Stockholm, Sweden to more than 30 countries around the world. Munters AgHort develops and manufactures energy-efficient climate control systems for the growth and development of agriculture and horticulture applications.

A3 Thinking, as it first emerged from Toyota in 1960s, is a mechanism, a template, to foster learning, engaging collaboration, and thoroughness (Sobek and Smalley, 2008). The A3 Thinking report is often represented in one of the following four variations:

  1. A3 Thinking for proposal
  2. A3 Thinking for problem solving
  3. A3 Thinking for status reporting
  4. A3 Thinking for competitive analysis

As a systematic approach for problem solving the goal of the A3 Thinking is not only to solve a problem and accommodate effective communication, but also to standardize the process and make it transparent (Shook, 2009).

Example of a generic A3 Thinking Template

In a nutshell, A3 thinking uses a single standard A3 format (297 x 420 mm or 11.7 x 16.5 in) sheet of paper to guide, capture and communicate a problem-solving process. Munters recognized the potential of the A3 Thinking and implemented it as part of the Hoshin Kanri catch-ball exercise for strategy deployment. The A3 Thinking has three distinguished advantages over traditional reporting: consistency and focus, rapid learning by using visuals to maximize the information fit on a single sheet, and all the information are displayed at once.

The R&D project leaders use A3s to capture the issues, final goals and plans in order to reach the target of each initiative. Below is an example of the A3 Thinking report from Munters.

Munters - A3 Example

What approach or medium do you use in your strategy or policy deployment exercises? Would a consistent and short documents (like A3s) help you to cut some time otherwise spent on lengthy reports and presentations?
