| 1.1 Identify client’s objectives |
|---|
| Step 1:Prepare a list of design objectives |
| Objectives |
|---|
| 01.Long lasting |
| 02.Low cost management |
| 03.Renewable parts |
| 04.Synchronization |
| 05.Easy to use |
1.2 Prioritize the identified design objectives
Priority among various objectives is set through a technique called Pair-wise Comparison Chart (PCC).
| Objective | Long Lasting | Low cost management | Renewable parts | Easy to use | score |
|---|---|---|---|---|---|
| Long lasting | *** | 0 | 0 | 0 | 0 |
| Low cost | 1 | *** | 1 | 1 | 3 |
| Renewable parts | 1 | 1 | 0 | *** | 1 |
| Easy to use | 1 | 0 | 1 | *** | 2 |
