L4 Practitioner8 modules · 38 h lessons plus practice

Plan, run and learn from test beds that prove a new product works safely before launch, so that a go or no-go decision rests on recorded results and not on hope.

Define test objectives with pass and fail limits.
Apply a test plan on a repeatable rig.
Analyse results with averages and failure counts.
Evaluate risk and safety before launch.
Create a test report with a go or no-go decision.

Task, condition and standard

Task

Plan and run a small test of a new product, record results over at least 30 trials, and write a report with a go or no-go.

Condition

About 10 weeks part-time. A working prototype, a safe test space, a stopwatch or meter, a spreadsheet, a mentor.

Standard

Each test has a pass limit set before it starts; the rig is repeatable; at least 30 trials are logged; failures are explained; the decision follows the data.

Who it is for: Makers, engineers, founders, product trainees, quality staff in small units. Requirements: Basic arithmetic. A prototype or sample product. Materials: lesson text, templates, rubric, check with answers.

lesson by lesson

8 modules with worked examples

Module 1 Define the product claims 4 hDefine

List what the product promises in numbers, for example lifts 10 kg or runs 6 hours.
Turn each promise into something you can measure.
Rank claims by risk to the user if they fail.
Write the conditions of use: heat, dust, voltage and user type.

Worked example. A solar lamp promises 6 hours of light; the test claim is at least 6 hours at 80 percent of starting brightness after a full charge.

Activity. Write five measurable claims for your product.

Standard to meet. Give each claim a number, a unit and a condition.

Module 2 Set pass and fail limits 4 hDefine

Choose limits before testing so results cannot bend them.
Use the rule that the product must meet the claim in at least 28 of 30 trials, which is about 93 percent.
Set a stop rule for dangerous failures: one smoke, spark or injury ends the test.
Get the limits agreed by a second person.

Worked example. Limit: lamp brightness at hour 6 must be at least 80 percent in 28 of 30 trials; any overheating above 60 degrees Celsius stops the test.

Activity. Write pass, fail and stop limits for each claim.

Standard to meet. Write the limits, date them, and have a reviewer sign them before the first trial.

Module 3 Design the test bed 5 hCreate

Build a rig that holds conditions the same each trial: fixed load, fixed temperature, fixed method.
Choose instruments and check their accuracy, such as a meter that reads within 2 percent.
Mark a safe zone with guards and an emergency switch.
Plan how many units to test: at least 5 units, 6 trials each, gives 30 trials.

Worked example. A bench with a fixed 5-watt load, a thermometer, a timer and a switch gives 5 lamps times 6 trials, 30 trials in all.

Activity. Sketch and build a rig, then run a dry trial.

Standard to meet. Repeat the dry trial within 5 percent.

Module 4 Write the test plan 4 hCreate

List each test with objective, steps, tools, number of trials and limit.
Add a risk table with cause, effect and control.
Assign roles: runner, recorder and checker.
Set dates and a place for results.

Worked example. Plan: 6 tests, 30 trials each for the main claim, 10 for side checks, 4 days at 3 hours a day.

Activity. Produce a plan of two to four pages.

Standard to meet. Link each test to a claim and a limit.

Module 5 Run trials and record 6 hApply

Follow the written steps exactly, with one change at a time.
Record every trial, including failures, in a table with date, unit, reading and note.
Never discard a result without a written reason.
Photograph set-up and key readings.

Worked example. Of 30 trials, 27 pass, 2 fail on battery drop and 1 is voided because the meter lead was loose; the voided trial is repeated.

Activity. Run at least 30 trials and keep the log.

Standard to meet. Log is complete, readable and every void has a reason.

Module 6 Analyse results 5 hAnalyse

Count passes and failures and show the pass rate.
Compute the average and the spread: lowest and highest.
Group failures by cause with a simple tally.
Find the likely cause of the top failure.

Worked example. Pass rate 28 of 30 is 93 percent; 2 failures both trace to a loose connector, so fix the connector.

Activity. Build a results table and a failure tally.

Standard to meet. Match the figures to a recount by a peer.

Module 7 Evaluate risk and safety 5 hEvaluate

Rate each risk by how likely and how severe it is.
Check user safety: heat, shock, sharp edges and misuse.
Compare results with rules the product must meet in India, such as Bureau of Indian Standards (BIS) marks where they apply.
Decide what to fix, accept or block.

Worked example. A connector fault has medium chance and high severity; it is fixed and 10 trials are repeated before any approval.

Activity. Complete a risk table for your product.

Standard to meet. Give every high risk a control and a re-test.

Module 8 Capstone: test report and decision 5 hCreate

Write the report: claims, limits, method, results, failures and risk.
State go, fix and retest, or no-go.
Give three next actions with owners and dates.
Present to a mentor panel.

Worked example. Report: 28 of 30 pass, connector fixed, 10 re-tests pass, decision go for a pilot batch of 100 units.

Activity. Submit the report and present it.

Standard to meet. Follow the limits in the decision, and trace every figure to the log.

assessment

How you are checked

Evidence: the work product from each module, kept in one folder with dates. A mentor and two peers mark it with this rubric. Pass: no criterion at 'Not yet'.

Marking rubric
Criterion	Not yet	Meets	Exceeds
Test design	Missing or unclear	Meets the stated check	Pre-set limits, repeatable rig and clear plan
Analysis	Guessing	Evidence kept	Correct pass rates, failure causes and justified decision
Records	Gaps	Complete	Complete and reviewed by a peer
Safety and ethics	Overlooked	Followed	Followed and taught to others

Ten-question check, with model answers

Q1. Why turn a promise into a number?

Model answer: A number can be tested and a vague promise cannot. (Covered in module 1: Define the product claims. To pass that module: Give each claim a number, a unit and a condition.)

Q2. Why set limits before testing?

Model answer: So the result cannot be reinterpreted to look better. (Covered in module 2: Set pass and fail limits. To pass that module: Write the limits, date them, and have a reviewer sign them before the first trial.)

Q3. What makes a test bed repeatable?

Model answer: Fixed conditions, checked instruments and a written method. (Covered in module 3: Design the test bed. To pass that module: Repeat the dry trial within 5 percent.)

Q4. What does a test plan list?

Model answer: Objective, steps, tools, trials, limits, roles and risks. (Covered in module 4: Write the test plan. To pass that module: Link each test to a claim and a limit.)

Q5. Why record failures?

Model answer: Failures show the weak points and protect honest decisions. (Covered in module 5: Run trials and record. To pass that module: Log is complete, readable and every void has a reason.)

Q6. Why group failures by cause?

Model answer: To fix the most common cause first. (Covered in module 6: Analyse results. To pass that module: Match the figures to a recount by a peer.)

Q7. Which risks must be fixed before launch?

Model answer: High-severity risks to user safety. (Covered in module 7: Evaluate risk and safety. To pass that module: Give every high risk a control and a re-test.)

Q8. What proves a go decision?

Model answer: Results meet the pre-set limits and risks are controlled. (Covered in module 8: Capstone: test report and decision. To pass that module: Follow the limits in the decision, and trace every figure to the log.)

Q9. Why change only one thing at a time?

Model answer: So you know which change caused the result. (Covered in: Task, condition and standard, near the top of this page.)

Q10. What is a stop rule?

Model answer: A condition that ends a test at once to prevent harm. (Covered in: Task, condition and standard, near the top of this page.)
