Weighting Technical Factors
The next step in our estimating process is to consider the technical factors of the project. To do this, use Table C-3 to assign a rating between 0 (irrelevant) and 5 (essential) for each topic. After rating each topic, multiply the weight by the rating to get an extended weight. The total extended weight for all technical factors is called the T factor.
| Technical Factor | Weight | Rating | Extended Weight (weight × rating) | Reason |
|---|---|---|---|---|
| 1. Distributed system | 2 | 3 | 6 | The system must be able to scale. |
| 2. Response or throughput performance objectives | 1 | 2 | 2 | Although response times aren't “hard,” they must be tolerable. |
| 3. End-user efficiency (online) | 1 | 3 | 3 | The system must be easy to ... |
