System Development Life Cycle: JAMB Computer Studies Questions, Answers & Notes

What System Development Life Cycle covers in the JAMB Computer Studies syllabus

The System Development Life Cycle (SDLC) is the set of stages used to build an information system. It usually begins with investigation and analysis — studying the current system to find its problems and requirements — often after a feasibility study that checks whether a proposed system is workable and worthwhile. Next comes design (planning how the new system will work and look — inputs, outputs, files, processes), then development/construction (building and coding it), then testing (checking it works correctly), then implementation (putting it into actual use, often with staff training) and finally maintenance (keeping it running well and improving it). The work is guided by a system analyst, who studies and designs the system. It is called a 'cycle' because maintenance and change can lead back to new analysis and improvement, and following it helps build reliable systems that meet users' needs. The main point: the SDLC builds an information system through analysis, design, development, testing, implementation and maintenance, guided by a system analyst.

For System Development Life Cycle, JAMB expects you to be able to:

• Define the SDLC and recall its stages (investigation/analysis, design, development, testing, implementation, maintenance)
• Recall the system analyst's role and the feasibility study
• Explain why it is a 'cycle' and its benefit (reliable systems that meet user needs)

Key facts & revision notes: System Development Life Cycle

These are the recurring points our System Development Life Cycle questions test — revise them until each feels automatic, then practise the questions above to lock them in.

• The System Development Life Cycle (SDLC) is the set of stages for building an information system.
• The first stage is investigation and analysis — studying the current system and its problems.
• System analysis studies the existing system to find its problems and requirements.
• System design plans how the new system will work and look (inputs, outputs, files, processes).
• System development (construction) is building and coding the new system.
• System testing checks that the new system works correctly before it is used.
• System implementation puts the new system into actual use (often with staff training).
• System maintenance keeps the system running well and improves it over time.
• A system analyst studies, designs and helps build information systems.
• A feasibility study checks whether a proposed system is workable and worthwhile.
• It is a 'cycle' because maintenance and change can lead back to new analysis and improvement.
• Following the SDLC helps build systems that are reliable and meet the users' needs.
• The SDLC is the stages of building a system.
• Studying the existing system is analysis.
• Planning how the new system works is design.
• Checking the new system works is testing.
• Putting the system into use is implementation.
• The person who designs systems is a system analyst.
• A study of whether a system is workable is a feasibility study.
• The main point is that the SDLC builds an information system through analysis, design, development, testing, implementation and maintenance, guided by a system analyst.

Worked examples

Three System Development Life Cycle questions with the answer and a short explanation, so you can see how the topic is set before you practise the full set.

How System Development Life Cycle is tested in JAMB Computer Studies

Our System Development Life Cycle bank holds 20 questions (2 easy, 14 medium, 4 hard). JAMB Computer Studies typically returns to System Development Life Cycle year after year, so steady practice on this topic is high-value revision. Questions are multiple-choice with four options, and at UTME pace you get roughly 40 seconds each — which is why timed practice matters.

How to answer System Development Life Cycle questions

Work the stem first and predict the answer before you look at the options; then eliminate the ones that contradict the key facts above. Watch for “which is not…”, “all of the above” and “except” style stems, which are where rushed candidates lose easy marks on System Development Life Cycle. If a calculation or a precise definition is involved, work it from first principles rather than guessing from a half-remembered rule. When two options look right, re-read the stem for the qualifier that separates them — JAMB rarely repeats an option by accident. If you are still unsure, eliminate the two weakest choices to lift your odds, flag the question, and move on; never burn a full minute on one Computer Studies item when the exam gives you about forty seconds each. Then come back to flagged questions with whatever time remains. The single most reliable way to get faster at System Development Life Cycle is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in System Development Life Cycle

The errors that cost marks on System Development Life Cycle are usually careless rather than conceptual: misreading a negative stem, confusing two similar terms, or rushing a definition you actually know. Candidates also over-rely on “expo” and last-minute cramming instead of understanding the topic — which fails the moment JAMB rephrases a familiar idea. Treat every option as a claim to be checked against the facts above, keep your working tidy for any calculation, and don’t change a considered answer on a hunch. Above all, revise System Development Life Cycle actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.
