Before you begin
- Apply the operational concept to the stated process, product or project and identify the assumptions behind any comparison or calculation.
Work on paper. Try each question before revealing help, and explain why your method works.

- Assess integration, data and implementation limits
ERP links information across business processes
Enterprise resource planning (ERP) integrates data and workflows across functions such as procurement, inventory, production, sales, finance and human resources. A shared record can reduce duplicated data and help teams see how an order affects stock, cost and capacity.
ERP may improve inventory control through timely stock visibility; costing and pricing through connected cost data; capacity utilisation through schedule information; responses to change through updated orders; workforce flexibility through skills and shift records; and management information through consistent reporting.
Integration creates benefits and implementation risk
Benefits depend on accurate data, suitable process design, user training and reliable system integration. Poor master data or an unsuitable workflow can spread errors quickly across the business.
Implementation can require licence, configuration, migration, training and downtime cost. Firms should map processes, clean data, test interfaces and use staged rollout and recovery procedures. ERP supplies information; managers still need to interpret it and question anomalies.
Pause and explain
How can ERP support inventory control?
Worked example
A manufacturer runs separate spreadsheets for stock, orders and production. Explain how ERP could help and one risk during implementation.
Show the worked solution
- A shared order can connect demand to stock and production schedules.
- Connected cost and capacity information may improve decisions.
- Incorrect data migration could create business-wide errors.
Answer ERP could connect orders, stock and production schedules so teams see shortages and capacity earlier; linked finance data may also improve costing and management information. If inventory records are migrated incorrectly, multiple functions may make decisions from the same wrong data. The firm should clean and reconcile records and test the system before full rollout.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A distributor wants ERP to improve inventory, pricing and delivery responses. Explain how shared records could support each objective.
Give me a hint
Trace one order through stock, cost and scheduling data.
Compare my reasoning
- Inventory records show available, reserved and incoming stock.
- Cost data can inform pricing and margin checks.
- Order and capacity status can guide delivery promises and replanning.
Shared inventory data can show available, reserved and incoming quantities. Connected cost records can support price and margin decisions. Orders linked to warehouse and transport capacity can help staff give realistic delivery dates and replan when a disruption occurs. Each improvement depends on accurate and timely records.
Look for these in your work
- All three outcomes are explained
- Data links are described
- Data quality is qualified
An ERP dashboard reports 500 units in stock, but a physical count finds 420. Explain immediate actions and one underlying data issue to investigate.
Give me a hint
Protect customer promises and reconcile transactions and record controls.
Compare my reasoning
- Check reservations, receipts, returns and recent stock movements.
- Correct or quarantine affected records before promising all 500 units.
- Investigate scanning, timing, access or data-migration errors.
The distributor should verify recent receipts, orders, returns and reservations, then correct the record and avoid promising unavailable stock. It should investigate whether scans were missed, transactions were delayed, access controls failed or opening data were migrated incorrectly and strengthen reconciliation.
Look for these in your work
- Customer and stock risk is managed
- Relevant transactions are checked
- Root cause and control are addressed
A small business is deciding whether to replace its separate systems with ERP. Recommend a staged evaluation before full commitment.
Give me a hint
Compare process needs, total cost, data readiness and rollout risk.
Compare my reasoning
- Map the processes and integration failures causing problems.
- Compare configuration, migration, training and support cost with benefits.
- Pilot one workflow, test recovery and define outcome measures before expansion.
The business should map which coordination problems the system must solve and compare ERP with simpler integration options. It should estimate configuration, migration, training, support and downtime costs, then pilot one workflow with reconciled data and a recovery test. It should scale only if inventory accuracy, cost information or response time improves enough to justify the investment.
Look for these in your work
- Business need is defined
- Total cost and alternatives are compared
- Pilot uses measurable criteria
Common mistakes
- Assuming integrated software guarantees efficient processes
- Ignoring data migration, training or downtime
- Treating dashboard data as a substitute for management judgement
