A mini repair shop role-play is a classroom exercise in which students act as technicians, customers and observers to practise handling a repair from the first greeting to payment.
Class: JSS 3
Subject: Computer Hardware and GSM Repair
Focus: Role-play exercise and real-world simulation.
Behavioural objectives
By the end of the lesson, students should be able to:
- Follow the five steps of the Technician’s Path when a customer brings a faulty device.
- Explain a simple hardware fault to a customer in plain English.
- Calculate a fair price from the cost of the part and the service fee.
- Complete a job card with the details needed to return the right device to the right person.
- Deal politely with angry, hurried and bargaining customers.
What is a Mini ICT Hub?
A Mini ICT Hub is a small classroom repair shop set up for practice, where students run a repair as if it were real.
- Setting: the classroom becomes the shop, and students act as business owners and customers.
- Aim: to see if you can handle a repair from the moment the customer walks in until the bill is paid.
What is tested in the exercise?
Three skills are tested: technical knowledge, customer service and pricing.
- Technical knowledge: can you explain the fault correctly?
- Customer service: are you polite and honest?
- Pricing: can you calculate a fair profit?
What does each technician need in the shop?
Every technician needs four items to make the shop look real.
- Workbench: a desk kept clean and tidy.
- Tools: a few tools, even if they are only for show today, such as a screwdriver set.
- Job card or logbook: a piece of paper for writing the details of each job.
- Price list: your charges, decided before you start.
What are the roles in the role-play?
The class is divided into three groups: technicians, customers and observers.
Role 1: The Technicians
- Listen: hear the customer’s complaint fully.
- Inspect: examine the “broken” device.
- Explain: say what is wrong in simple words.
- Price: give a clear charge.
- Behave: be professional and keep your workbench clean.
Role 2: The Customers
- Gadgets: bring “broken” devices, such as your own phone or a notebook pretending to be a laptop.
- Nice customers: polite and patient.
- Difficult customers: some are in a big hurry, and others argue and try to reduce the price.
- The secret: technicians must not know which type of customer you are playing.
Role 3: The Observers (The Judges)
Observers walk around with a pen and paper and mark the technicians.
| Question to ask | What it checks |
|---|---|
| Who was the most polite? | Customer service |
| Who explained the tech stuff in simple English? | Technical knowledge and communication |
| Who kept their workbench the neatest? | Professional habits |
What are the steps of the Technician’s Path?
The Technician’s Path is the five-step routine a technician follows when a customer comes to the desk.
- The Welcome: greet the customer. “Good morning! Welcome to [Your Name] Repairs. How can I help you today?”
- The Interview: ask questions about the fault. “When did it stop working? Did it fall in water? Was it charging when it went off?”
- The Diagnosis: look at the device, use your “tools”, then explain the problem simply. “Your charging port is dusty and needs cleaning.”
- The Quote (Pricing): tell the customer the cost. “The part is ₦1,000 and my service fee is ₦500. Total is ₦1,500.”
- The Job Card: write the customer’s name and the phone’s serial number, so you do not give the wrong phone to the wrong person later.
How do you fill in a job card?
A job card is a written record of each device brought to the shop.
- Customer’s name: so you know who owns the device.
- Phone number: so you can call when the job is done.
- Device and serial number: to identify the exact device. On a phone, the IMEI number is shown by dialling *#06#.
- Fault reported: what the customer says is wrong.
- Quoted price: the agreed total.
- Date: the day the device was received.
How do you calculate a fair price?
A fair price covers the cost of the part and your service fee, and leaves a profit.
- Total charge: cost of the part to the customer + service fee.
- Profit: selling price minus the cost price.
- Loss: happens when you charge less than the cost price.
| Item | Amount |
|---|---|
| Part charged to customer | ₦1,000 |
| Service fee | ₦500 |
| Total to pay | ₦1,500 |
- Tip: decide your charges before you start, and write them on your price list.
What are the practice scenarios?
There are three scenarios to act out: the water damage panic, the angry student and the bargain hunter.
Scenario A: The “Water Damage” Panic
- Situation: a customer runs in crying that their phone fell in a bucket of water. They want to turn it on to check their photos.
- Technician’s task: stop them from turning it on, explain why it is dangerous, and explain what the cleaning process will be.
- Why it is dangerous: power running through a wet circuit board can cause a short circuit and more damage.
- Safe advice: switch the phone off, do not charge it, and remove the battery, SIM and memory card if they can be removed.
- Cleaning process: open the phone, clean the board with a suitable cleaning liquid such as isopropyl alcohol, and let it dry fully before testing.
Scenario B: The “Angry Student”
- Situation: a student brings back a laptop you “fixed” yesterday, complaining it is still slow.
- Technician’s task: do not get angry, check the laptop again, and apologise for the trouble.
- Find out: is it a new problem or the old one?
Scenario C: The “Bargain Hunter”
- Situation: a customer wants to change a screen. You charge ₦10,000, but they say they only have ₦4,000.
- Technician’s task: politely explain the cost of the screen and why you cannot do it for that price without losing money.
- Example: if the screen cost you ₦8,000, charging ₦4,000 means a loss of ₦4,000.
How should a technician deal with customers?
A good technician is polite, honest and clear with every customer.
- Be polite: greet every customer and stay calm, even with difficult ones.
- Be honest: tell the true fault and the true price.
- Use simple words: avoid technical terms the customer cannot follow.
- Stay neat: a clean workbench shows care.
- Keep records: always complete the job card.
Evaluation
Discuss these questions after the role-play.
- What was the hardest part about talking to the “Difficult Customer”?
- Did anyone forget to write down the customer’s name? Why is that a problem?
- How did it feel to tell a customer a price? Were you confident or shy?
- What is one thing you would do differently if a real customer walked in right now?
Assignment
Write a short job card and price list for a phone with a damaged screen. Include the customer’s name, the fault, the part cost, your service fee and the total to pay.
