ISTQB Certified Tester Advanced Level – Test Analyst (CTAL-TA) — Question 9

You are testing a hospital patient management system. New or amended patient data is captured by hospital administrators using an in-house patient capture application and transmitted to one or more hospital departments depending on the nature of the medical condition. Each department operates its own software package. There has been a change to the patient capture application and you are going to run a series of interoperability tests.
Which TWO of the following are potential interoperability defects?
The patient name field is truncated on one of the receiving department systems.
Hospital administrators find the new patient-capture application screens difficult to navigate.
Two department systems are unable to recognise the format of international telephone numbers for foreign patients.
Existing patient data takes too long to retrieve by the patient-capture application.
There are spelling errors in the field names on some screens.

Answer options

• A. a, b.
• B. b, d.
• C. c, e.
• D. a, c.

Correct answer: D

Explanation

The correct answer is D, as the patient name field truncation and the inability of department systems to recognize international phone number formats are both interoperability issues that affect data exchange between systems. The other options refer to usability problems or performance issues, which are not directly related to interoperability.
