Analysis, Design and Implementation
Name the five stages of a systematic approach to solving a problem with software, in order.
Show the answer
Analysis, design, implementation, testing and evaluation. They are presented in that order, but in practice work often returns to an earlier stage — particularly design and implementation, which may be repeated in cycles.
The 2 subtopics
One subtopic is one session. Work down the list.
| Subtopic | What it covers | Questions |
|---|---|---|
| Analysis, Design and Implementation | Recall questions on the five stages of a systematic approach, establishing and clarifying requirements, abstraction in analysis, iterative design and modular structure, and implementation. | 12 |
| Testing and Evaluation | Recall questions on demonstrating correctness, normal, boundary and erroneous test data, acceptance testing and its evidence, the criteria and limits of evaluation, and sequential against iterative development. | 12 |
How the guide is worked
Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.
-
Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
-
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
-
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.
Read the full method, the return schedule and the research behind it.
