ISTQB Exam CTAL-TTA Topic 6 Question 12 Discussion

Actual exam question for ISTQB's CTAL-TTA exam

Question #: 12
Topic #: 6

Your team is now accountable for the support and enhancement of a payroll system that has been in production for many years and modified by many different developers. It has been noticed by management that small functional enhancements take much longer than equivalent changes on more recently developed systems. You have been tasked with implementing improved testing approaches that will help to identify the root cause of this problem.

Which of the following is the best technique to apply in this scenario?

AOrthogonal arrays

BExploratory analysis

CStatic analysis

DData flow analysis

Show Suggested Answer

Suggested Answer: C

Static analysis is the best technique for identifying the root causes of issues in a legacy system where small functional enhancements take disproportionately long to implement. This technique involves examining the code without executing it to detect potential vulnerabilities, coding errors, and complexities. Static analysis can highlight problematic code segments and inefficient coding practices that may contribute to the increased time required for implementing changes, thereby assisting in addressing these systemic issues efficiently.

This payroll system sounds like a real Frankenstein's monster. I bet the developers who worked on it back in the day are all long gone, leaving the rest of us to clean up the mess. Good luck with that!

Exploratory analysis could be a good starting point, but I'd want to pair that with some more rigorous techniques like static analysis or data flow analysis to really get to the root of the problem.

Orthogonal arrays? Really? I think that's a bit overkill for this scenario. Keep it simple, focus on the fundamentals.

I agree, focusing on the fundamentals with static analysis would be more practical in this scenario.

Data flow analysis could be really helpful in tracing the impact of changes through the system. That could shed some light on why simple enhancements are taking so long.

Static analysis seems like the way to go here. If the code has been modified by many different developers over the years, it's likely to have a lot of technical debt and hidden issues that need to be uncovered.
