Which of the following requirement gathering techniques is about building an application in a short period to get the feedbacks from the users prior to continue develop the final system?

Question

BlackTom AI · Accepted Answer

A prototype is a quickly built, working model of the system used to collect user feedback and validate requirements before committing to full development, so "Prototype" is the correct choice.

1) Relevant knowledge points and concepts
- Prototyping: creation of an early, often incomplete version of a system (throwaway or evolutionary) to explore requirements and design, support usability testing, and obtain stakeholder feedback.
- Wireframe: a low-fidelity, usually non-interactive schematic of layout and navigation, focusing on structure rather than function.
- Software Development Life Cycle (SDLC): the full set of phases (requirements, design, implementation, testing, deployment, maintenance) describing how software is developed and maintained.
- Joint Application Design (JAD): facilitated workshops where stakeholders and developers collaborate to elicit and agree on requirements.

2) Step-by-step reasoning
- The question specifies "building an application in a short period to get the feedbacks from the users prior to continue develop the final system." That emphasizes a temporary working version used to validate requirements and user interactions.
- Match that description to the definitions: prototyping explicitly involves building a working or semi-working system quickly to solicit feedback; wireframes are static and low-fidelity; SDLC is the overall process, not a rapid-build feedback technique; JAD is a collaborative elicitation method, not actually building a short application.
- Therefore the description aligns precisely with prototyping.

3) Intermediate steps (concept mapping)
- Short build + user feedback → interactive model technique → prototyping.
- Not static diagrams (wireframes) → eliminates wireframe.
- Not full lifecycle methodology → eliminates SDLC.
- Not workshop-based elicitation → eliminates JAD.

4) Why the correct answer is correct
- Prototypes allow stakeholders to interact with a tangible version of the system, reveal misunderstandings, uncover missing or changing requirements, and reduce risk before costly full-scale development. These are exactly the goals implied by the question phrase.

5) Why other options are incorrect
- Wire frame: shows layout but typically not a functioning application for real user feedback on behavior.
- Software development life cycle: an overarching process, not a short-build feedback technique.
- Joint Application Design: a facilitated meeting technique for eliciting requirements, not rapid construction of an application.

6) Conclusion
The described technique is prototyping; this confirms the provided answer "Prototype."
