| **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. |
