Echocardiogram Software Development Lifecycle 2 — Questions and Answers
Question 1: Which SDLC phase involves gathering requirements from cardiologists and sonographers for a new echocardiography reporting module?
- Design
- Requirements analysis (Correct answer)
- Testing
- Deployment
Correct answer: Requirements analysis
Requirements analysis collects and documents stakeholder needs before any design or development begins.
Question 2: In the context of echocardiography software, what is the primary purpose of user acceptance testing (UAT)?
- To stress-test the server hardware
- To verify the software meets clinical workflow needs before go-live (Correct answer)
- To write the system's technical documentation
- To allocate database storage for DICOM images
Correct answer: To verify the software meets clinical workflow needs before go-live
UAT confirms that the software satisfies real-world clinical requirements as defined by end users such as echo technicians.
Question 3: A hospital's echo lab is migrating its image archiving software. Which SDLC phase ensures old DICOM data is transferred correctly to the new system?
- Requirements
- Design
- Implementation/migration (Correct answer)
- Retirement
Correct answer: Implementation/migration
Data migration is carried out during the implementation phase, ensuring existing records are accurately transferred.
Question 4: What does 'iterative development' mean in the context of echocardiography software updates?
- Releasing one large update every five years
- Continuously improving the software through repeated cycles of development and feedback (Correct answer)
- Delegating all updates to the hardware vendor
- Freezing features after initial deployment
Correct answer: Continuously improving the software through repeated cycles of development and feedback
Iterative development means releasing incremental improvements based on user feedback rather than waiting for a single large release.
Question 5: Which document produced during the SDLC specifies how the echo reporting system must handle HL7 messages from the EHR?
- User manual
- System requirements specification (SRS) (Correct answer)
- Marketing brochure
- Training schedule
Correct answer: System requirements specification (SRS)
The SRS formally documents functional and integration requirements, including HL7 interface behavior.
Question 6: A software bug causes the echo workstation to crash when exporting reports in PDF format. Which SDLC phase addresses this after deployment?
- Planning
- Design
- Maintenance (Correct answer)
- Requirements
Correct answer: Maintenance
Post-deployment defects are resolved during the maintenance phase of the SDLC.
Question 7: In Agile SDLC, what is a 'sprint' as it applies to developing an echocardiography measurement tool?
- A network speed test for DICOM transfers
- A fixed-length work cycle during which specific features are developed and delivered (Correct answer)
- A type of cardiac stress test
- A final deployment checklist
Correct answer: A fixed-length work cycle during which specific features are developed and delivered
A sprint is a time-boxed iteration (typically 1–4 weeks) in which the team completes a defined set of development tasks.
