Purpose of the lesson

Measure actual production performance against approved schedules, quality standards, productivity targets, and budgets, and develop a performance-improvement plan where required.

Practical outcome

By the end of this lesson, you must be able to:

• Measure production-schedule adherence.
• Monitor production output and quality.
• Compare actual production costs with the budget.
• Measure rework and production shrinkage.
• Calculate employee productivity.
• Measure equipment utilisation.
• Identify root causes of non-performance.
• Develop and monitor a production-improvement plan.

1. Gather the required information

Obtain:

• Approved production plan and schedule
• Production-order records
• Actual start and completion times
• Planned and actual output
• Quality standards
• Inspection and rejection reports
• Rework records
• Material-issue and usage records
• Scrap and shrinkage reports
• Employee attendance and labour-hour records
• Equipment-availability and downtime records
• Maintenance reports
• Production budget
• Actual production costs
• Previous performance reports
• Customer and replenishment priorities

Use information covering the same line, product and reporting period.

2. Validate the performance data

Before calculating results:

1. Confirm the reporting period.
2. Verify production-order and SKU references.
3. Reconcile reported output with inventory receipts.
4. Check units of measure.
5. Separate completed, rejected and reworked units.
6. Confirm labour and equipment hours.
7. Verify authorised downtime and schedule changes.
8. Reconcile material issues, returns and waste.
9. Record missing or unreliable information.
10. Retain an audit trail of corrections.

3. Measure schedule adherence

Schedule adherence measures whether production orders were completed according to the approved production schedule.

Use:

Schedule adherence = Orders completed as scheduled ÷ Total scheduled orders × 100

Example:

• Scheduled orders: 20
• Orders completed as scheduled: 17

Schedule adherence = 17 ÷ 20 × 100 = 85%

You may also measure quantity adherence:

Production-plan attainment = Actual output ÷ Planned output × 100

If planned output was 10,000 units and actual output was 9,200:

Production-plan attainment = 9,200 ÷ 10,000 × 100 = 92%

Schedule-adherence record

Use the organisation’s approved definition of “completed as scheduled.”

4. Measure production quality

Quality measures may include:

• First-pass yield
• Defect rate
• Rejection rate
• Customer-return rate
• Specification compliance
• Rework rate

First-pass yield

First-pass yield = Units meeting requirements without rework ÷ Total units produced × 100

If 950 of 1,000 units pass without rework:

First-pass yield = 950 ÷ 1,000 × 100 = 95%

Defect rate

Defect rate = Defective units ÷ Total units produced × 100

Separate defects by product, line, shift, machine and cause.

5. Measure production cost

Include applicable costs such as:

• Direct materials
• Direct labour
• Equipment operation
• Energy
• Maintenance
• Setup and changeover
• Quality control
• Rework
• Scrap
• Overtime
• Contracted services

Use:

Cost variance = Budgeted production cost − Actual production cost

A negative result indicates that actual cost exceeded the budget.

Calculate:

Production cost per good unit = Total production cost ÷ Accepted finished units

Example:

• Actual production cost: R500,000
• Accepted finished units: 10,000

Cost per good unit = R500,000 ÷ 10,000 = R50

6. Measure rework

Rework is additional processing required to correct products that failed to meet requirements during the first production attempt.

Use:

Rework rate = Units requiring rework ÷ Total units produced × 100

Also record:

• Rework labour hours
• Material used
• Equipment hours
• Cost
• Delay caused
• Final outcome

Rework register

Rework reduces available capacity and may delay other production orders.

7. Measure production shrinkage

Production shrinkage is the unexplained or unacceptable loss of material during production after normal authorised usage and waste have been considered.

Use:

Material variance = Actual material used − Standard material allowed

If 1,000 finished units should use 2,000 kg but actual usage is 2,150 kg:

Material variance = 2,150 − 2,000 = 150 kg unfavourable

Where the organisation measures shrinkage directly:

Shrinkage rate = Unexplained material loss ÷ Total material issued × 100

Separate:

• Normal process loss
• Approved scrap
• Damaged material
• Rework consumption
• Unexplained shrinkage

8. Measure human-resource productivity

Use an output measure appropriate to the production activity.

Labour productivity = Accepted output ÷ Labour hours used

Example:

• Accepted output: 8,000 units
• Labour hours: 400

Labour productivity = 8,000 ÷ 400 = 20 units per labour hour

Also monitor:

• Output per employee
• Labour cost per unit
• Overtime
• Absenteeism
• Training and competency
• Idle time

Do not improve productivity by ignoring quality or safety requirements.

9. Measure equipment utilisation

Use:

Equipment utilisation = Actual productive operating time ÷ Available equipment time × 100

Example:

• Available line time: 160 hours
• Productive operating time: 120 hours

Equipment utilisation = 120 ÷ 160 × 100 = 75%

Separate time used for:

• Productive operation
• Setup and changeover
• Planned maintenance
• Breakdown
• Material waiting
• Employee waiting
• Quality stoppage

High utilisation is not automatically favourable if it causes inadequate maintenance, poor quality or excessive work-in-progress.

10. Monitor equipment performance

Where information is available, assess:

• Availability
• Performance rate
• Quality output
• Breakdown frequency
• Mean repair time
• Maintenance compliance

A combined measure may be expressed as:

Overall Equipment Effectiveness = Availability × Performance × Quality

Use the organisation’s approved formula and express each value as a decimal before multiplying.

11. Prepare the production scorecard

12. Identify performance gaps

For each measure:

1. Confirm the target.
2. Calculate the actual result.
3. Determine the variance.
4. Identify the affected product, line or shift.
5. Assess the effect on customer and replenishment requirements.
6. Determine the cost and capacity effect.
7. Prioritise the required response.

13. Determine root causes

Investigate causes across:

Use production records, employee input, observations and a method such as the Five Whys.

14. Implement immediate containment

Containment may include:

• Stop production where safety or quality is at risk.
• Isolate defective output.
• Inspect work-in-progress.
• Correct machine settings.
• Reallocate trained employees.
• Expedite critical materials.
• Activate backup equipment.
• Reschedule urgent production.
• Notify affected warehouse and customer-service teams.

Containment controls the immediate effect but does not replace permanent improvement.

15. Develop the production-improvement plan

Include:

• Immediate containment
• Permanent corrective action
• Required resources
• Responsibility
• Completion date
• Performance target
• Monitoring frequency
• Escalation requirement

16. Monitor improvement

Track:

• Production output
• Schedule completion
• Defects and rework
• Material usage and shrinkage
• Labour productivity
• Equipment downtime and utilisation
• Costs
• Corrective-action status

Verify that improvement in one measure does not reduce safety, quality or performance elsewhere.

17. Prepare the production-performance report

Include:

• Reporting period
• Products and lines assessed
• Data sources
• Targets and actual results
• Variances and trends
• Root causes
• Customer and operational effects
• Corrective actions
• Responsible persons and dates
• Remaining risks
• Recommendations

Lesson Summary

To monitor production activities, validate source data and compare actual output with the approved schedule, quality requirements and budget. Measure schedule adherence, plan attainment, first-pass quality, rework, material shrinkage, labour productivity, equipment utilisation and cost per good unit. Investigate significant variances to identify their underlying causes and operational effects. Apply immediate containment where required, implement a measurable performance-improvement plan and monitor results until production targets are achieved.
