Chapter 4: Coordinate supply chain operations

4.1 Coordination of supply chain operations

Coordination of supply chain operations is the work of keeping the linked activities of buying, receiving, storing, producing and delivering goods in step with one another, so that goods and information flow without gaps or duplication. A procurement manager coordinates suppliers, the stores, the user departments and the transport so that what is needed arrives when it is needed, in the right quantity and at an agreed cost. Example: a furniture workshop that buys timber, hardware and varnish must time its orders to the production schedule, or the carpenters stand idle while the store is full of the wrong items.

Coordination as a strategic function in procurement

Coordination joins planning to day-to-day action. It aligns the procurement schedule with what suppliers can deliver, matches stock levels to forecast demand and fits transport to delivery promises. Example: a building materials distributor with two depots coordinates its cement and roofing orders, so that bulk purchases are shared between the depots and neither runs out of stock.

• Demand forecast alignment: procurement plans follow the expected demand, which prevents overstocking and shortages.
• Supplier relationship management: long-term dealings with reliable suppliers improve dependability and flexibility.
• Inventory synchronisation: stock levels in the stores and outlets are coordinated, so that working capital is not tied up in idle stock.
• Logistics integration: transport schedules are fitted to delivery commitments, which reduces lead times.
• Compliance coordination: every purchase follows the procurement law and the entity's own rules.

Communication and information flow in coordination

Coordination depends on timely and accurate information passing among the user departments, the procurement unit, the stores and the suppliers. The information includes purchase orders, delivery schedules, stock levels and feedback on quality. Example: a water-pump assembler tells its supplier of motors the weekly assembly plan, so that the supplier delivers motors in step with the line.

• Shared information systems: a stock or procurement software system holds one set of data that all the parties use.
• Regular coordination meetings: scheduled meetings with suppliers and users settle delays and changes early.
• Standard documents: uniform forms and reports reduce misunderstandings.
• Feedback channels: suppliers and users have a way to report on quality and timeliness.
• Skilled staff: staff trained in communication and in the systems in use pass information correctly.

Challenges in coordinating supply chain operations and how to reduce them

• Supplier inconsistency: unreliable delivery times and quality are reduced by using more than one qualified supplier for key items.
• Information silos: departments that hold separate data cause delays, so a common system is used.
• Logistical constraints: poor roads and long distances lengthen lead times, so safety stock and contingency routes are planned.
• Procedural delays: slow approvals hold up orders, so the workflow is simplified and time limits are set.
• Demand variability: sudden changes in need are met by joint forecasting with suppliers and by flexible contracts.

Measuring the effectiveness of coordination

Measures show where coordination is weak. They are tracked each period and compared with the targets.

• Order accuracy rate: the percentage of orders that arrive without errors.
• On-time delivery rate: the share of deliveries that meet the scheduled date.
• Inventory turnover: how often stock is used and replaced, which shows how well stock follows demand.
• Supplier performance score: a combined rating of quality, timeliness and responsiveness.
• Cost variance: the difference between the budgeted and the actual cost of purchases.

4.1.1 Definition of supply chain process

A supply chain process is a set of connected activities, carried out in a fixed order, that turns a need for goods or services into delivery to the user and handles what comes back. It begins with the identification of the need and ends with the goods in the hands of the customer, including any returns. Each process has an input, a series of steps, an output and an officer who is responsible. Example: the process of buying timber for a workshop runs from the requisition, through the quotation and the order, to the receipt, the inspection and the payment.

• Series of linked activities: the output of one activity is the input of the next, such as an approved requisition becoming an order.
• Defined start and end: each process begins with a trigger, such as a requisition, and ends with a result, such as goods in stock.
• Repeatable: the process follows standard steps, so that it gives the same quality each time.
• Cross-functional: it involves several units, such as users, procurement, stores, finance and transport.
• Measurable: the time, cost and accuracy of the process can be measured and improved.

4.1.2 Types of supply chain processes

Supply chain processes are commonly grouped by what they do. The five groups below follow the flow of goods from planning to return, and a supporting process of information and control runs alongside all of them.

Planning process

Planning decides what will be needed, how much, when and by what means. It turns demand forecasts, budgets and stock levels into a plan for purchasing and supply. Example: a water-pump assembler plans its quarterly purchases of motors and casings from the sales forecast.

• Demand forecasting: estimating future requirements from past use and expected orders.
• Budgeting: setting the money available for each category of purchase.
• Purchase planning: deciding quantities, timing and suppliers.
• Capacity planning: checking that stores and transport can handle the planned volumes.

Sourcing process

Sourcing is the process of finding suppliers and obtaining goods from them. It covers the choice of supplier, the pricing and the contract. Example: a building contractor's procurement unit invites quotations for steel bars from qualified suppliers and awards the order to the best.

• Requisition and specification: the user states the need and describes the item.
• Supplier identification and selection: possible suppliers are identified and compared.
• Quotation, tender or negotiation: prices and terms are obtained and evaluated.
• Ordering: a purchase order or contract is issued to the chosen supplier.
• Receipt and payment: the goods are received, checked and paid for.

Making process

The making process changes materials into finished goods, or assembles components. It applies to entities that produce, and the procurement unit coordinates it by supplying the right materials on time. Example: a workshop that makes office desks for sale draws timber and screws from the store according to the production schedule.

• Scheduling production: deciding what is made and when.
• Issuing materials: releasing materials from the store against a production order.
• Production and assembly: converting the materials into finished goods.
• Quality checks: inspecting products against the specification.
• Recording output: updating stock records with the goods produced and the materials used.

Delivery process

Delivery is the process of moving goods to the customer or the user, and recording the transfer. It includes order handling, warehousing, transport and proof of delivery. Example: a distributor of roofing sheets picks orders in the warehouse, loads a lorry and obtains a signed delivery note from the site.

• Order processing: confirming the order and checking the stock.
• Warehousing and picking: locating and preparing the goods.
• Transport: moving the goods by a chosen route and vehicle.
• Proof of delivery: a signed delivery note shows what was received and when.
• Invoicing: the supplier bills for the goods delivered.

Return process

The return process handles goods that come back because they are faulty, wrong, damaged or surplus, and the waste and unwanted items that remain. It protects the entity from paying for goods that do not meet the order. Example: a stores unit finds that a delivery of paint tins includes damaged ones and returns them to the supplier for credit.

• Return notification: the supplier is told of the fault and the quantity.
• Inspection and documentation: the faulty goods are recorded, and photographs or inspection notes are attached.
• Return authorisation: the supplier issues approval and instructions for the return.
• Transport and receipt: the goods are sent back, and receipt is confirmed.
• Credit or replacement: the entity receives a credit note or a replacement.
• Handling of surplus and waste: unwanted items are passed to disposal under the entity's rules.

Supporting process of information and control

Beside the five groups, a supporting process records transactions, controls approvals and reports on performance. It includes budgeting controls, documentation, supplier records and reports, and it keeps the other processes in order and open to audit.

Chapter Summary

This chapter explored the coordination of supply chain operations by first defining the supply chain process as a series of interconnected activities that ensure the flow of goods and services from suppliers to customers. It then examined various types of supply chain processes that organizations employ to optimize efficiency and responsiveness. The discussion progressed to the meaning of supply chain reports, highlighting their role in monitoring and improving supply chain performance. Different types of supply chain reports were identified, alongside the detailed steps involved in developing these reports to ensure accuracy and relevance. The chapter also outlined the essential contents of a supply chain report and emphasized the benefits these reports bring to decision-making and operational control. Finally, the maintenance of supply chain management documents was covered, describing key document types such as local purchase orders, requests for quotations and proposals, purchase requisition notes, delivery notes, and invoices, all of which are critical for effective supply chain management.
