Design process & SDLC, Higher Level(7 marks)

Quick ones on Design process & SDLC.

(a)In the waterfall model of development, how are the stages done?
  1. In short repeated cycles with user feedback
  2. Each stage is finished before the next starts
  3. All at the same time
(b)What is one main advantage of iterative (agile) development?
  1. Requirements are fixed at the start
  2. No testing is needed
  3. Feedback can be acted on during development
(c)In software design, what is a prototype?
  1. An early working model used to test ideas
  2. The user manual written for the product
  3. The final released product given to users

Which of these is a non-functional requirement for a booking app?

  1. Users can book a table for any date
  2. Users can cancel a booking online
  3. Pages must load in under 2 seconds
Show the answer

Pages must load in under 2 seconds

Functional requirements say what the system does; non-functional ones say how well it does it, such as speed, security or accessibility.

A simple drawing of a screen layout, with no working features, is a…

  1. Prototype
  2. Flowchart
  3. Wireframe
Show the answer

Wireframe

A wireframe shows where buttons, text and images go. A prototype is a working early version that users can try out.

A method that builds software in short cycles, getting feedback each time, is…

  1. Linear development
  2. Iterative development
  3. The waterfall model
Show the answer

Iterative development

Iterative (agile) development repeats design, build and test in short cycles. Waterfall finishes each stage fully before starting the next.

Design process & SDLC, 3 marks

In a staged (waterfall) process, which stage comes straight after design?

  1. Build the solution
  2. Investigate the problem
  3. Plan the project
Show the answer

Build the solution

The order is investigate, plan, design, build, test, evaluate. Building (coding) turns the design into a working product.
