```| **Step**                        | **Action**                                                                          |
|---------------------------------|-------------------------------------------------------------------------------------|
| **Step 1: Prepare the Selection Matrix** | - Create a matrix with the four pencil holder concepts as columns.                    |
|                                      | - List the selection criteria (Ease of handling, Ease of use, Readability of settings,  |
|                                      |   Dose metering accuracy, Durability, Ease of manufacture, Portability) as rows.      |
|                                      | - Assign weights to each criterion based on their importance (as shown in your matrix). |
|                                                                                         |
| **Step 2: Rate the Concepts**        | - Rate each concept for each criterion on a scale of 1 to 5 (1 being poor, 5 being     |
|                                      |   excellent) based on how well it performs for that criterion (refer to your provided  |
|                                      |   ratings in the matrix).                                                           |
|                                                                                         |
| **Step 3: Rank the Concepts**        | - Calculate the weighted scores for each concept using the formula:                  |
|                                      |   - Total Score (Sj) = ∑ (Rating * Weight) for all criteria.                           |
|                                      | - Rank the concepts based on their total scores.                                      |
|                                                                                         |
| **Step 4: Combine and Improve the Concepts** | - Consider if there are any opportunities to combine or improve the concepts based on |
|                                          |   team insights.                                                                      |
|                                                                                         |
| **Step 5: Select One or More Concepts** | - Choose the concept with the highest total score as the most suitable pencil holder  |
|                                      |   concept for a product development team member who frequently moves between sites.   |
|                                      |   You can select more than one concept if there's a close ranking or if they cater to   |
|                                      |   different customer preferences.                                                     |
|                                                                                         |
| **Step 6: Reflect on the Results and the Process** | - Review the selected concept(s) and the overall concept selection process to ensure |
|                                                  |   they align with team goals and customer needs.                                      |
|                                                                                         |
| **Conclusion:** | In your provided example, concept DF has the highest total score, making it the preferred choice for the product development team member on the move. |
