Use project management tools (Gantt charts, PERT charts)
Project Management – Tools for A‑Level IT 9626
Why Project Management Matters 📚
Think of a school project like building a LEGO set. Project management tools help you decide what pieces you need, when to add them, and how to avoid missing a step. They keep the team on track, make deadlines clear, and help you spot problems before they become big issues.
Gantt Charts – The Project Timeline ???
A Gantt chart is like a calendar that shows when each task starts and ends. Each bar represents a task, and its length shows how long the task will take.
Analogy: Imagine you’re planning a road trip. The Gantt chart tells you when you’ll leave, how long the drive will be, and when you’ll arrive at each stop.
| Task | Start Date | Duration (days) |
|---|---|---|
| Define Scope | 01‑Sep | 2 |
| Research | 03‑Sep | 5 |
| Prototype | 08‑Sep | 7 |
| Testing | 15‑Sep | 3 |
| Final Report | 18‑Sep | 2 |
In exams, you may be asked to interpret a Gantt chart or create one from a list of tasks. Practice drawing bars on a grid and labeling start/end dates.
PERT Charts – Planning the Path 🗺️
PERT (Program Evaluation Review Technique) helps you estimate how long a task might take when you’re not sure. It uses three time estimates:
- Optimistic (O) – best case
- Most Likely (M) – realistic case
- Pessimistic (P) – worst case
The expected time is calculated as: $E = \frac{O + 4M + P}{6}$
Analogy: Think of planning a hike. You estimate the fastest route (optimistic), the normal route (most likely), and the route that takes detours (pessimistic). PERT gives you a balanced estimate of how long the hike will actually take.
| Task | Optimistic (O) | Most Likely (M) | Pessimistic (P) | Expected (E) |
|---|---|---|---|---|
| Research | 2 | 4 | 6 | 4.33 |
| Prototype | 5 | 8 | 12 | 8.33 |
| Testing | 1 | 3 | 5 | 2.33 |
In the exam you might need to calculate expected times or draw a PERT network diagram. Practice using the formula and visualising the tasks as nodes connected by arrows.
Exam Tips & Quick Checklist 🚀
- Read the question carefully – does it ask for a timeline or a probability estimate?
- Label all tasks clearly; use abbreviations if space is limited.
- Show your calculations for PERT – the examiner will check your maths.
- Use colour or shading to differentiate critical path tasks.
- Check that all dates are consistent – no overlapping start dates unless the task can run in parallel.
- Practice drawing charts by hand – you’ll be faster and less likely to make mistakes.
Remember: clarity and accuracy win the exam. Keep your charts neat, label everything, and double‑check your maths.
