Echocardiogram Software Development Lifecycle 5

Question 1

Which SDLC phase involves creating wireframes and UI mockups for a new echocardiography structured reporting interface?

Accepted Answer

System/UI design

Answer

Wireframes and UI mockups are produced during the design phase to visualize the user interface before development begins.

Question 2

A critical security vulnerability is found in an echo PACS system after release. Fixing it without adding new features is an example of:

Accepted Answer

Corrective maintenance

Answer

Corrective maintenance repairs defects — including security vulnerabilities — discovered in the released system.

Question 3

What is the primary purpose of a 'code review' in the SDLC for echo software development?

Accepted Answer

To have peers inspect code for defects, security issues, and adherence to standards before merging

Answer

Code reviews catch bugs and enforce coding standards early, reducing the cost of defects found later in testing or production.

Question 4

In Agile SDLC, a 'retrospective' meeting held after each sprint serves what purpose for an echo software team?

Accepted Answer

Reflecting on what went well and what to improve in the next development cycle

Answer

Retrospectives are a core Agile ceremony for continuous process improvement by identifying successes and obstacles from the completed sprint.

Question 5

Which risk is most relevant to the SDLC for software that automatically measures LV ejection fraction from echo images?

Accepted Answer

Algorithm producing clinically inaccurate measurements that affect patient diagnosis

Answer

For FDA Class II medical device software, inaccurate automated measurements carry direct patient safety risk and must be rigorously validated.
