In which phase is the customer shown detailed sketches of screen designs by the vendor?

Question

Design Phase focuses on creating user interface mockups, wireframes, and detailed screen sketches that show layout, navigation, and visual elements before code is written.

1) Relevant knowledge points and concepts
- Software Development Life Cycle (SDLC) phases: typical stages include Requirements/Analysis, Design, Coding/Implementation, Testing/QA, and Deployment/Maintenance.
- Deliverables by phase: the Design phase produces models, UI mockups, screen sketches, prototypes, and detailed specifications that guide developers and inform customers about look-and-feel and interaction.
- Purpose of screen sketches: communicate layout, fields, controls, flow, and visual hierarchy to stakeholders for feedback and approval prior to building functionality.

2) Step-by-step reasoning process
- Step 1: Interpret the phrase “detailed sketches of screen designs” as wireframes/mockups and UI prototypes.
- Step 2: Match that deliverable to the SDLC phase whose goal is to define how the system will look and behave visually — the Design phase.
- Step 3: Confirm that customers are typically shown these designs at the Design phase to review and approve the user interface before implementation begins.

3) Intermediate steps (no numeric calculations required)
- Map each answer option to its typical primary activity:
  a. Coding Phase = implementing functionality in code (not creating initial detailed screen sketches).
  b. Testing Phase = validating functionality, finding/fixing defects (not producing design sketches).
  c. Deployment Phase = releasing the system to production (post-design and implementation).
  d. Design Phase = producing UI sketches, wireframes, and visual specifications.

4) Why the correct answer is correct
- The Design phase explicitly produces and presents detailed screen sketches to customers so they can review layout, flow, and usability before developers code the interfaces. This prevents costly rework and ensures stakeholder agreement.

5) Why the other options are incorrect
- Coding Phase: focuses on writing code from the approved designs, not creating initial screen sketches.
- Testing Phase: focuses on verifying the implemented system against requirements, not on showing design mockups.
- Deployment Phase: concerns installation and rollout, occurring after design, coding, and testing.

6) Conclusion
- The correct choice is d. Design Phase, which matches the provided answer. Final answer: d. Design Phase.
