ISTQB Exam CTAL-TTA Topic 5 Question 17 Discussion

Actual exam question for ISTQB's CTAL-TTA exam

Question #: 17
Topic #: 5

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.

Wow, this question is like a blast from the past. I bet the developers who worked on this payroll system are still using floppy disks and rotary phones.

Orthogonal arrays? What is this, a geometry class? I'm pretty sure we need to focus on the actual code, not some fancy mathematical technique.

C'mon, static analysis? That's so old-school. We need to get our hands dirty with some exploratory analysis to really understand what's going on under the hood.

Data flow analysis sounds like the way to go here. It'll help us understand the complex dependencies in the system and identify the root cause of the slow changes.
