Five vendors are being considered for a service. The evaluation committee evaluated each vendor on six aspects – Cost, Customer Service, Features, Quality, Reach, and Reliability. Each of these evaluations are on a scale of 0 (worst) to 100 (perfect). The evaluation scores on these aspects are shown in the radar chart. For example, Vendor 1 obtains a score of 52 on Reliability, Vendor 2 obtains a score of 45 on Features and Vendor 3 obtains a score of 90 on Cos
Solution
Understanding the set :-
This is a radar chart set,
This type of chart is used to compare multiple items (in this case, vendors) across several categories. Each axis represents a different evaluation criterion.
The chart evaluates vendors based on the following 6 criteria:
- Reliability
- Reach
- Quality
- Features
- Customer Service
- Cost
Each criterion ranges from 0 to 90 (higher is better).
Also, each vendor can be seen as :
- Vendor 1: Blue line with circles
- Vendor 2: Orange line with squares
- Vendor 3: Green line with triangles
- Vendor 4: Yellow line with diamonds
- Vendor 5: Dark blue line with pentagons
This was an easy set, which just needs you to understand how to read this chart, then the questions were a softball.
| Parameters | Vendor 1 | Vendor 2 | Vendor 3 | Vendor 4 | Vendor 5 |
|---|---|---|---|---|---|
| Reliability | 52 | 40 | 75 | 26 | 60 |
| Reach | 80 | 58 | 63 | 46 | 70 |
| Quality | 72 | 69 | 62 | 40 | 48 |
| Features | 40 | 45 | 56 | 90 | 75 |
| Customer Services | 55 | 41 | 50 | 70 | 28 |
| Cost | 77 | 81 | 90 | 71 | 50 |
From the chart we can make the following table.
| Parameters | Vendor 1 | Vendor 2 | Vendor 3 | Vendor 4 | Vendor 5 |
|---|---|---|---|---|---|
| Reliability | 52 | 40 | 75 | 26 | 60 |
| Reach | 80 | 58 | 63 | 46 | 70 |
| Quality | 72 | 69 | 62 | 40 | 48 |
| Features | 40 | 45 | 56 | 90 | 75 |
| Customer Services | 55 | 41 | 50 | 70 | 28 |
| Cost | 77 | 81 | 90 | 71 | 50 |
Top 3 on Reliability: Vendor 3, Vendor 5
Top 3 on Reach: Vendor 1, Vendor 5
Top 3 on Quality: Vendor 1, Vendor 2
Top 3 on Features: Vendor 4, Vendor 5
Top 3 on Customer Services: Vendor 4, Vendor 1
Top 3 on Cost: Vendor 3, Vendor 2
=> Vendor 1: 3 times
Vendor 2: Only once
Vendor 3: 2 times
Vendor 4: 2 times
Vendor 5: 3 times
Here 1 and 5 comes 3 times.
Therefore, answer is vendor 1 and 5.
