Purpose of the lesson
Develop objective criteria for measuring demand-execution performance, allocate measurement responsibilities and evaluate actual results, variances and non-conformance.
Practical outcome
By the end of this lesson, you must be able to:
- Select valid demand-execution performance measures.
- Establish measurable performance targets.
- Define measurement formats, data sources and timeframes.
- Develop criteria for identifying policy and process non-conformance.
- Measure positive and negative performance variances.
- Rate the degree, severity and implications of performance.
- Allocate monitoring responsibilities.
- Evaluate performance and recommend corrective action.
1. Gather the required information
Obtain:
- Demand-execution operational plan
- Customer-order schedule
- Customer contracts and service-level agreements
- Demand forecast
- Actual customer orders
- Inventory and allocation reports
- Back-order information
- Delivery records
- Customer complaints and returns
- Demand-management policies
- Order-processing procedures
- Existing performance reports
- Organisational objectives and customer priorities
Confirm the scope, reporting period and responsible operational area.
2. Define the evaluation scope
State clearly:
- Process being evaluated
- Customers and products covered
- Facility or business unit
- Reporting period
- Operational objectives
- Applicable policies and procedures
- Service-level commitments
- Intended users of the evaluation report
A clear scope prevents unrelated data from affecting the result.
3. Translate objectives into performance measures
Develop measures that show whether demand-execution objectives are being achieved.
| Objective | Performance measure |
|---|---|
| Match supply with customer demand | Forecast accuracy |
| Process customer orders correctly | Order accuracy |
| Supply complete orders | Order-fill rate |
| Deliver according to commitment | On-time delivery |
| Minimise outstanding demand | Back-order rate |
| Process orders efficiently | Order cycle time |
| Maintain customer service | Complaint or satisfaction result |
| Control fulfilment expenditure | Cost per fulfilled order |
Each measure must be relevant to the operational objective.
4. Define each measure
Prepare a measurement specification for every KPI.
| Field | Information required |
|---|---|
| Measure name | Clear KPI title |
| Purpose | What the measure evaluates |
| Definition | What is included and excluded |
| Formula | Approved calculation |
| Data source | System or document used |
| Target | Required performance level |
| Frequency | Daily, weekly or monthly |
| Owner | Person accountable for the result |
| Data collector | Person compiling the information |
| Reviewer | Person validating the result |
| Escalation level | Action required when performance fails |
Using written definitions ensures that different employees calculate the measure consistently.
5. Develop appropriate targets
Targets should be:
- Linked to operational objectives
- Measurable
- Realistic but challenging
- Time-bound
- Supported by reliable data
- Consistent with customer agreements
- Approved by authorised stakeholders
Use suitable sources such as:
- Contractual service levels
- Approved budgets
- Historical performance
- Operational capacity
- Customer requirements
- Internal benchmarks
- External benchmarks where reliable
Do not select a target merely because it produces a favourable result.
6. Specify measurement formats
Select a format that makes results easy to calculate, compare and act upon.
Suitable formats include:
- Daily monitoring register
- Weekly exception report
- Monthly scorecard
- Performance dashboard
- Variance report
- Back-order ageing report
- Customer-level service report
- Corrective-action register
Performance scorecard template
| Measure | Target | Actual | Variance | Status | Owner | Required action |
|---|---|---|---|---|---|---|
| Order accuracy | 98% | 96% | −2% | Below target | Order manager | Investigate errors |
| Order-fill rate | 97% | 99% | +2% | Above target | Inventory manager | Maintain control |
7. Set measurement timeframes
Specify:
- Data collection frequency
- Calculation date
- Reporting deadline
- Review date
- Escalation deadline
- Corrective-action deadline
- Follow-up measurement period
Use a frequency suited to the measure:
| Measure | Suggested timeframe |
|---|---|
| Urgent back orders | Daily |
| Order-processing delays | Daily or weekly |
| Forecast accuracy | Weekly or monthly |
| Order-fill rate | Weekly or monthly |
| Customer-service performance | Monthly |
| Long-term demand trends | Monthly or quarterly |
Critical operational failures should not wait for the monthly report before being escalated.
8. Develop policy non-conformance criteria
Policy non-conformance occurs when an approved organisational rule is not followed.
Examples include:
- Stock allocated outside approved customer priorities
- Orders accepted without required authorisation
- Customer information handled incorrectly
- Unapproved substitutions
- Performance data deliberately changed
- Back orders removed without valid resolution
- Customer commitments made outside delegated authority
Define:
- The policy requirement
- Evidence of compliance
- Conditions constituting non-conformance
- Severity level
- Responsible reviewer
- Required escalation
9. Develop process non-conformance criteria
Process non-conformance occurs when an approved operational procedure is not followed.
Examples include:
- Order information not validated
- Orders released after the cut-off
- Stock not allocated in time
- Back orders not recorded
- Revised dates not communicated
- Required system updates omitted
- Complaints not escalated
- Delivery documents not retained
Non-conformance criteria register
| Requirement | Evidence | Non-conformance condition | Severity |
|---|---|---|---|
| Record all back orders | Back-order register | Outstanding quantity not recorded | Major |
| Validate customer order | Approved order record | Order released with missing data | Moderate |
| Apply priority rules | Allocation report | Stock allocated outside approved priority | Major |
10. Establish variance criteria
Calculate:
Variance = Actual performance − Target performance
Example:
- Target order accuracy: 98%
- Actual order accuracy: 95%
Variance = 95% − 98% = −3 percentage points
Interpret results consistently:
- Positive variance: Actual performance exceeds the target.
- Zero variance: Actual performance meets the target.
- Negative variance: Actual performance falls below the target.
For measures where lower values are better, such as back-order rate or cost, interpret the direction carefully. A result above the maximum target is unfavourable.
11. Rate the degree of performance
Use predefined ranges.
| Rating | Example performance against target |
|---|---|
| Significantly above target | More than 5% favourable |
| Above target | Up to 5% favourable |
| On target | Meets the approved target |
| Moderately below target | Up to 5% unfavourable |
| Significantly below target | More than 5% unfavourable |
Adapt the ranges to the importance and sensitivity of the measure.
12. Determine severity
Rate the seriousness of underperformance or non-conformance.
| Severity | Description |
|---|---|
| 1—Low | Limited effect; routine correction |
| 2—Moderate | Noticeable service or efficiency effect |
| 3—High | Important customer or operational commitment affected |
| 4—Major | Serious cost, compliance or continuity effect |
| 5—Critical | Safety, legal or essential-service failure |
Consider:
- Number of customers affected
- Quantity outstanding
- Duration
- Financial effect
- Contractual consequence
- Reputational effect
- Risk of recurrence
- Effect on essential customers
Overperformance should also be evaluated. It may indicate genuine improvement, an unsuitable target, excess resources or inaccurate data.
13. Allocate responsibilities
Use a responsibility matrix.
| Activity | Data collector | KPI owner | Reviewer | Corrective-action owner |
|---|---|---|---|---|
| Record customer orders. | Order administrator | Order manager | Customer-service manager | Relevant process manager |
| Calculate backorders. | Inventory controller | Inventory manager | Supply-chain manager | Planning manager |
| Measure delivery performance | Distribution analyst | Transport manager | Customer-service manager | Transport manager |
Ensure that:
- The responsible person has access to the data.
- The KPI owner has authority to act.
- Results receive independent review.
- Escalation responsibilities are clear.
- No important measure remains unassigned.
14. Collect and validate performance data
Check:
- Completeness
- Accuracy
- Correct reporting period
- Consistent units
- Duplicate records
- Approved exclusions
- Changes to customer commitments
- Traceability to source records
Document any limitation that could affect the reliability of the evaluation.
15. Evaluate demand-execution performance
