Explanation
This question is based on a case study that compares four scenarios for implementing a new system for a bank.
The case study provides the following information about the duration of each scenario:
Scenario 1: 6 months
Scenario 2: 9 months
Scenario 3: 10 months
Scenario 4: 7 months
The question asks for the time difference in days between the shortest and longest implementation. The shortest implementation is Scenario 1, which is 6 months or 180 days. The longest implementation is Scenario
3, which is 10 months or 300 days. Therefore, the time difference in days is 300 - 180 = 120 days. References:
The case study is available in the CBAP Exam Sample Questions and Exam Blueprint document1. The answer is also verified by the CBAP Exam Answer Key document2. Both documents are accessible from the IIBA website3.
