The free BugBot lessons that teach this point, a robot to try it on, and the past-paper questions that test it.
Lessons that teach it
- A14.1 The systems lifecycle and feasibility Software development, law and ethics
The stages from feasibility to maintenance, the three kinds of maintenance, and scoring a feasibility study. - A14.2 Development methodologies Software development, law and ethics
Waterfall, spiral, agile, extreme programming and rapid application development: how each works, when to use it, and planning agile sprints. - A14.3 Analysis: requirements and success criteria Software development, law and ethics
