Purpose of the lesson

Compare the stock-replenishment plan with actual production progress, identify variances and constraints, and realign production and material-replenishment schedules to meet operational priorities.

Practical outcome

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

• Compare stock-replenishment requirements with the production schedule.
• Identify and record production variances.
• Assess production-line and resource capacity.
• Identify finished-product and material shortages.
• Realign production schedules around operational constraints.
• Realign material-replenishment orders with revised production plans.
• Communicate and monitor approved schedule changes.

1. Gather the required information

Obtain:

• Current stock-replenishment plan
• Approved production schedule
• Actual production-progress report
• Customer-service priority list
• Customer delivery schedule
• Warehouse picking plan
• Finished-goods stock report
• Material inventory report
• Bills of materials
• Open material orders
• Production-line capacities
• Employee and shift availability
• Equipment and maintenance information
• Quality and downtime reports
• Current operational constraints

Confirm that all records cover the same planning period.

2. Compare replenishment requirements with production

For each SKU, compare:

• Replenishment quantity
• Required completion date
• Scheduled production quantity
• Actual output
• Remaining quantity
• Production-line allocation
• Expected completion date
• Warehouse requirement
• Customer priority

Production comparison

3. Calculate production variances

Use:

Quantity variance = Actual output − Planned output

If planned output is 800 units and actual output is 650 units:

Quantity variance = 650 − 800 = −150 units

Calculate schedule variance as the difference between the planned and expected completion dates or times.

Record positive and negative variances consistently.

4. Create a variance register

Include:

Possible variances include:

• Quantity below or above plan
• Late start or completion
• Lower production rate
• Excessive downtime
• Material usage variance
• Quality rejection
• Changed replenishment requirement
• Changed production priority

5. Identify production-capacity constraints

Check:

Production-line capacity

Available output = Available production hours × Standard production rate

If a line is available for six hours at 200 units per hour:

Available output = 6 × 200 = 1,200 units

Adjust available hours for:

• Setup and changeover
• Planned maintenance
• Cleaning
• Breaks
• Quality inspections
• Approved downtime

Human-resource capacity

Confirm:

• Number of employees available
• Required skills
• Shift coverage
• Operator authorisation
• Absence and leave
• Supervision and quality support

Equipment capacity

Confirm:

• Line and machinery availability
• Maintenance status
• Shared-equipment conflicts
• Tooling and setup requirements
• Breakdown recovery time
• Packaging capacity

6. Identify production shortages

A production shortage occurs when actual and expected output cannot meet the replenishment requirement by the required date.

Use:

Production shortage = Required replenishment − Available finished stock − Expected completed production

Record:

Also identify material shortages that prevent production.

7. Assess material availability

Use the current bill of materials and revised production quantity.

Gross material requirement = Revised production quantity × Material required per finished unit

Net material requirement = Gross requirement + Safety allowance − Available material − Confirmed receipts

Exclude:

• Damaged materials
• Quarantined materials
• Unconfirmed supplier deliveries
• Materials reserved for other approved orders

Material status

8. Determine the operational effect

For every variance or shortage, identify the effect on:

• Stock replenishment
• Warehouse picking
• Vehicle loading
• Customer delivery
• Customer priority
• Inventory availability
• Material orders
• Cost
• Downstream production orders

Prioritise constraints that affect urgent customer commitments or several supply-chain activities.

9. Realign the production schedule

Follow these steps:

1. Confirm the replenishment requirement.
2. Verify the variance or constraint.
3. Identify affected production orders.
4. Recalculate available capacity.
5. Apply customer and operational priorities.
6. Evaluate authorised alternatives.
7. Revise quantities, sequences and completion times.
8. Update material requirements.
9. Obtain approval.
10. Communicate and monitor the revised schedule.

Corrective options

Use an appropriate combination of:

• Change the production sequence.
• Move work to a compatible line.
• Split production between lines.
• Reallocate trained employees.
• Arrange an authorised additional shift.
• Reduce changeovers by grouping similar products.
• Reschedule lower-priority production.
• Expedite critical materials.
• Use an approved substitute material.
• Reschedule maintenance where authorised.
• Revise the replenishment or delivery date.

Do not move an order to another line without confirming product compatibility and quality requirements.

10. Prepare the realigned schedule

Check that the schedule is feasible using the available line, labour, equipment, materials and time.

11. Realign material-replenishment orders

Use the revised production schedule to update material requirements.

For each order:

• Recalculate gross and net material requirements.
• Confirm the required-at-production date.
• Review existing purchase orders.
• Identify shortages and excess orders.
• Expedite, postpone or amend orders where authorised.
• Confirm supplier capacity.
• Update delivery and receiving dates.
• Link the material order to the production order.

Realigned material-order schedule

Consider the effect on storage capacity, cost and other production orders before changing supplier commitments.

12. Coordinate linked operational schedules

Ensure that the revised schedules remain aligned:

Material delivery
       ↓
Production completion
       ↓
Finished-goods availability
       ↓
Warehouse picking
       ↓
Transport dispatch
       ↓
Customer delivery

Notify procurement, production, inventory, warehouse, transport and customer-service teams of approved changes.

13. Monitor the revised plan

Track:

• Material-order status
• Material receipt and inspection
• Production start and completion
• Output quantity
• Downtime
• Quality results
• Finished-goods availability
• Warehouse release
• New constraints and variances

Update the schedule promptly when actual performance changes.

Lesson Summary

To coordinate production schedules, compare replenishment requirements with scheduled and actual production, calculate variances and identify capacity or material shortages. Determine how each issue affects inventory, picking, transport and customer commitments. Apply approved priorities and revise production quantities, sequences, resources and completion dates. Recalculate material requirements and realign supplier orders with the updated plan. Communicate approved changes across the supply chain and monitor production and material availability until the revised commitments are achieved.
