Software Development Lifecycle Flashcards

Which type of system maintenance involves updating a health IT system to comply with new ICD coding guidelines?

Answer: Adaptive maintenance

Adaptive maintenance modifies the system to keep it current with changes in its environment, such as updated regulatory or coding standards.

What is the purpose of a 'feasibility study' in the SDLC planning phase?

Answer: To determine whether the proposed system is technically, financially, and operationally viable

A feasibility study assesses whether the project is worth pursuing by evaluating technical, economic, and operational factors.

Regression testing after a software patch ensures that:

Answer: Previously working features have not been broken by the update

Regression testing re-runs existing test cases to confirm that a change has not introduced new defects in previously functioning functionality.

In SDLC system design, a 'prototype' is used to:

Answer: Give stakeholders a tangible preview of the interface to gather early feedback

Prototypes are early working models that help stakeholders visualize the system and provide feedback before full development begins.

Which SDLC model is best suited when requirements are well understood and unlikely to change?

Answer: Waterfall

Waterfall's sequential, document-driven approach works best when all requirements are stable and clearly defined upfront.

What is the role of a 'System Analyst' in the SDLC?

Answer: Bridging the gap between business users and technical developers by translating requirements

A system analyst gathers business requirements and translates them into technical specifications that developers can implement.

Which diagram shows the sequence of activities and decision points in a business process for an EHR workflow?

Answer: Activity diagram (flowchart)

Activity diagrams or flowcharts map out the steps and branching decisions in a workflow, making them ideal for documenting EHR processes.
