Unit 4.2 — Operations planning and control
Learning outcomes (from the 9587 syllabus). This note is complete when every bullet below is covered.
Learning outcomes
- Importance of operations planning and control (set targets, timelines and operation method; ensure plans are adhered to; act if not)
- Activities of planning and control: loading, sequencing, scheduling, monitoring and control
This topic is not covered in the coursebook (the book teaches critical path analysis instead, which 9587 does not require). Learn the five activities below.
Running example: Swift Logistics must plan each day’s parcel deliveries so nothing is late.
Big picture
In plain English: once a business knows what to produce, it must decide who does what, in what order, and by when — and then check it is happening. That is operations planning and control.
Analogy: planning deliveries is like planning your homework. You decide which subjects to do (loading), the order to do them (sequencing), when to start each (scheduling), check your progress (monitoring), and speed up if you fall behind (control).
Core content
1. Importance of operations planning and control
Planning and control allow a business to:
- Set targets (how many parcels, by when)
- Set timelines (deadlines for each step)
- Choose the operation method (how the work will be done)
- Ensure the plan is followed, and take corrective action if it is not
Without this, work is disorganised: resources sit idle, deadlines are missed, and customers are disappointed.
Swift Logistics plans that each courier delivers 60 parcels by 6pm. This target and timeline tell every courier what “on time” means, and let Swift spot a courier falling behind and fix it.
2. The activities of planning and control
| Activity | Meaning | Question it answers |
|---|---|---|
| Loading | Assigning work to people, machines or vehicles | “Who (or what) does which job?” |
| Sequencing | Deciding the order in which jobs are done | “Which job comes first?” |
| Scheduling | Setting the start and finish times of each job | “When does each job happen?” |
| Monitoring | Checking actual progress against the plan | “Are we on track?” |
| Control | Taking corrective action when there is a deviation | “What must we fix?” |
At Swift Logistics each morning: loading assigns parcels to couriers and vans; sequencing orders deliveries by location (nearby stops first); scheduling sets a 9am–6pm delivery window; monitoring tracks each van’s GPS against the plan; and control sends a backup courier when one van is delayed.
Analysis & evaluation points (AO3/AO4)
- Good planning reduces idle time and delays — resources are used fully and deadlines are met.
- But over-planning is rigid — too much planning wastes time and cannot cope with surprises.
- Monitoring is useless without control — knowing you are behind but doing nothing changes nothing.
- Flexibility matters — plans must allow for unexpected events (a breakdown, bad weather).

Worked examples (PEEL)
PEEL = Point → Explain → Example → Link. Use this structure for every written answer.
Worked example 1 — “Explain” (6 marks)
Question: Explain the difference between sequencing and scheduling.
- P (Point): Sequencing is the order of jobs; scheduling is the timing of jobs.
- E (Explain): Sequencing decides which job comes first, second and third, while scheduling assigns each job a start and finish time.
- E (Example): Swift Logistics sequences a courier’s stops nearest-first (order), and schedules them so all are completed between 9am and 6pm (timing).
- L (Link): Together they ensure the work is done in a logical order within the available time.
Worked example 2 — “Evaluate” (10 marks)
Question: Evaluate the importance of monitoring and control to a business.
- P (Point): Monitoring and control ensure the plan is actually achieved.
- E (Explain): A plan only works if the business checks progress and corrects deviations; otherwise problems are discovered too late.
- E (Example): Swift Logistics’ GPS monitoring spots a delayed van early, so control (sending a backup) keeps the delivery promise.
- L (Link): This protects customer satisfaction and the business’s reputation.
- Evaluate (AO4): However, constant monitoring costs money (tracking systems, supervisors) and too much control can stress staff. On balance, the benefits outweigh the costs for time-critical businesses, but the level of monitoring should match the cost of failure.
Application bank (Singapore quick reference)
| Idea | Singapore example |
|---|---|
| Scheduling | Changi Airport scheduling aircraft landings and gate times |
| Loading | Restaurants assigning chefs to stations (grill, pastry) |
| Sequencing | Hawker stalls sequencing orders to minimise waiting |
| Monitoring/control | Grab tracking drivers and reassigning rides when needed |
Exam technique
- How it appears: a case study describes a delivery/production delay and asks how planning and control could prevent it.
- Model skeleton for “improve operations planning”: state the problem → apply loading/sequencing/scheduling to fix it → add monitoring and control to keep it on track.
- Common pitfalls: mixing up the five activities; describing planning without control.
