Solutions Selection Matrix: Your Guide to Choosing the Best Lean Six Sigma Solutions
Welcome to! If you’re a Lean Six Sigma professional or someone new to this exciting field, you’re in the right place. Today, we’re diving into the Solutions Selection Matrix, a vital tool in your Lean Six Sigma toolkit. Whether you’re a Yellow Belt, Green Belt, Black Belt, or even a Master Black Belt, mastering this matrix will enhance your project management skills and boost your career development.

What is the Solutions Selection Matrix?

The Solutions Selection Matrix is a decision-making tool that helps teams evaluate and prioritize potential solutions to a problem. It’s a structured method that ensures the most effective and efficient solution is chosen, aligning with Lean Six Sigma principles of reducing waste and improving processes.

Why Use a Solutions Selection Matrix?

In any Lean Six Sigma project, selecting the right solution is crucial. The wrong choice can lead to wasted resources, time, and effort. The Solutions Selection Matrix offers several benefits:
  • Objective Decision-Making: It removes personal biases by providing a clear, quantitative evaluation of each solution.
  • Efficiency: Helps in quickly narrowing down the best options, saving time and effort.
  • Clarity: Provides a transparent rationale for decisions, making it easier to communicate with stakeholders.
  • Alignment: Ensures that the chosen solution aligns with business goals and Lean principles.

How to Create a Solutions Selection Matrix

Creating a Solutions Selection Matrix involves several steps. Let’s break it down:

1. Define the Criteria

Start by identifying the criteria that are important for evaluating your solutions. Common criteria include:
  • Cost: How much will it cost to implement the solution?
  • Impact: What is the potential impact on the problem?
  • Feasibility: How easy is it to implement the solution?
  • Time: How long will it take to implement the solution?
  • Resources: What resources are required for implementation?

2. List the Solutions

Brainstorm all possible solutions to the problem. Include even the wildest ideas—sometimes, the most unconventional solutions can be the most effective.

3. Rate Each Solution

Rate each solution against each criterion. Use a consistent scale (e.g., 1 to 5) where a higher number indicates a better score. Be as objective as possible, and involve your team to gather diverse perspectives.

4. Calculate the Total Scores

Sum the scores for each solution. This will give you a total score that helps in comparing the solutions objectively.

5. Analyze the Results

Look at the total scores and see which solutions stand out. Consider any qualitative factors that might not be fully captured by the scores, and use your judgment to make the final decision.

Example of a Solutions Selection Matrix

Let’s illustrate this with an example. Suppose you’re working on a Lean Six Sigma project to reduce customer wait times in a call center. Here’s how your matrix might look:
SolutionCost (1-5)Impact (1-5)Feasibility (1-5)Time (1-5)Resources (1-5)Total Score
Implement IVR System4534319
Hire More Agents2443215
Train Existing Agents5355523
Improve CRM Software3444419
In this example, training existing agents scores the highest, indicating it might be the best solution to reduce wait times.

Tips for Using the Solutions Selection Matrix

  1. Involve Your Team: Diverse perspectives lead to better decision-making. Ensure all relevant stakeholders are involved in the process.
  2. Be Consistent: Use the same scale for all criteria and solutions to ensure fair comparisons.
  3. Review Regularly: As projects evolve, revisit your matrix to ensure the chosen solution still holds up.
  4. Document Everything: Keep detailed records of your criteria, ratings, and decisions. This transparency helps in justifying your choices and provides a reference for future projects.


The Solutions Selection Matrix is an indispensable tool in Lean Six Sigma, helping professionals make informed, efficient, and objective decisions.
