Design focus
The calculated design focus is Carry weight (1), Battery endurance (2), Filtration effectiveness (3). 3 of 3 selected factors have complete inputs.
All selected factors will be addressed in the design, including those with a lower relative importance. Relative importance shows where to focus engineering attention. Rank 1 is where to sharpen your pencil: understand what drives its performance, define how to control it, and make sure it is right. Use the order to focus effort while meeting every factor’s design target.
The order combines the engineer-reviewed customer rank, the target-to-current performance ratio, and the Kano adjustment. It frames the next design discussion; the research below explains the customer priorities and the engineer’s review.
Must-have expectations to retain in the design: Filtration effectiveness.
Next design steps
- Frame the next design task around improving Carry weight from rank 2 to rank 1 (1 = strongest). Define an appropriate design requirement from the customer need. Confirm the target with customers.
- Frame the next design task around improving Battery endurance from rank 3 to rank 2 (1 = strongest). Define an appropriate design requirement from the customer need. Confirm the target with customers.
- Frame the next design task around improving Filtration effectiveness from rank 4 to rank 1 (1 = strongest). Define an appropriate design requirement from the customer need. Confirm the target with customers.
Research justification
These inputs are illustrative. No customer interviews, Kano survey or market research is claimed.

1 · Carry weight
Attractive / delighter3 × ((6 − 1) ÷ (6 − 2)) × 1.5 = 5.63 raw importance. This is position 1 in the calculated order.
The engineer ranks current performance 2 and targets 1 on the 1–5 scale, where 1 is strongest, indicating an improvement to address.
Example assumption: reduced weight adds convenience after core requirements are met.
Sample customer rank for this illustrative example.
2 · Battery endurance
Performance2 × ((6 − 2) ÷ (6 − 3)) × 1.2 = 3.2 raw importance. This is position 2 in the calculated order.
The engineer ranks current performance 3 and targets 2 on the 1–5 scale, where 1 is strongest, indicating an improvement to address.
Example assumption: longer trips increase the value of operating time between charges.
Sample customer rank for this illustrative example.
3 · Filtration effectiveness
Must-have1 × ((6 − 1) ÷ (6 − 4)) × 1 = 2.5 raw importance. This is position 3 in the calculated order.
The engineer ranks current performance 4 and targets 1 on the 1–5 scale, where 1 is strongest, indicating an improvement to address.
Example assumption: core treatment performance is essential to the product's purpose. Validate with testing and customer research.
