Five vendors are being considered for a service – Video Solution


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 Cost.

Answer: 1

Q.3 List of all the vendors who are among the top two scorers on the maximum number of aspects is:

  1. Vendor 1 and Vendor 2
  2. Vendor 1 and Vendor 5
  3. Vendor 2 and Vendor 5
  4. Vendor 2, Vendor 3 and Vendor 4
Answer: 2

Q.4 List of all the vendors who are among the top three vendors on all six aspects is:

  1. Vendor 1 and Vendor 3
  2. Vendor 3
  3. Vendor 1
  4. None of the Vendors
Answer: 2

Solution:
The scores of venders given in graph can be tabulated as below:
  Reliability Reach Quality Features Customer S Cost Total
Vendor 1 52 80 70 40 55 80 377
Vendor 2 40 60 70 45 40 80 335
Vendor 3 75 60 60 55 50 90 390
Vendor 4 25 45 40 90 70 70 340
Vendor 5 60 70 50 75 28 60 343

  1. Median of reliability = 52; median of quality = 60; median of customer s = 50 median of cost = 80 Clearly the median of customer s is minimum.
  2. The vender which has highest total will have highest average. vendor 3 has highest total thus highest average.
  3. Vendor 1 and 5 have 3 top two scores each.
  4. Clearly vendor 3
