Process Views of Supply Chains including Cycle View and Push-pull View

Process view of a supply chain looks at it as a series of linked business processes that cut across functions and organisations, rather than as a set of separate departments. It shows how activities such as ordering, procurement, production, and delivery flow from supplier to customer. Two main frameworks are the cycle view, which divides the chain into repeating cycles between stages, and the push/pull view, which classifies processes by whether they respond to forecasts or actual orders. For example, Dell assembles computers only after receiving customer orders (pull), while Hindustan Unilever produces many products in advance (push). This view helps firms improve coordination, efficiency, and decision-making.

Importance of Process Views:

1. Provides an End-to-End Perspective

A process view treats the supply chain as one connected flow from supplier to customer, rather than isolated departments. It helps managers see how decisions in one stage, such as purchasing or production, affect every other stage. This end-to-end visibility exposes hidden gaps, duplication, and handoff delays. For example, Toyota maps its entire flow from steel supplier to dealer to spot waste across the chain. A holistic view supports better planning and avoids local optimisation, where one function improves its own results at the cost of the whole chain.

2. Improves Coordination Among Partners

Because processes cross functional and company boundaries, the process view clarifies who does what, when, and with what information. It aligns suppliers, manufacturers, distributors, and retailers around shared goals and timelines. For example, Walmart and Procter & Gamble coordinate replenishment through shared sales data and agreed ordering processes. Clear process ownership reduces conflict, miscommunication, and delays. Strong coordination also lowers the bullwhip effect, since partners respond to the same demand signals rather than guessing independently.

3. Clarifies Roles and Responsibilities

Each process has defined inputs, outputs, activities, and owners. This makes responsibilities clear between internal teams and external partners, such as who places orders, who ships, and who handles returns. Clarity reduces overlap and finger-pointing when problems arise. For example, in the cycle view, the customer order cycle and procurement cycle each specify which party initiates and completes the activity. Defined accountability makes performance easier to measure and manage, especially in international chains with many participants.

4. Supports Better Decision-Making

The process view links strategic, planning, and operational decisions to specific supply chain processes. The push/pull view helps managers decide which activities should follow forecasts and which should follow actual orders, shaping inventory, capacity, and lead-time choices. For example, Dell uses pull for assembly and push for component stocking. By understanding the nature of each process, managers can choose suitable inventory levels, flexibility, and technology, leading to more informed and consistent decisions.

5. Enables Process Improvement and Efficiency

Mapping processes reveals bottlenecks, delays, and non-value-adding steps. Firms can then redesign, automate, or eliminate them using tools such as lean, Six Sigma, and business process reengineering. For example, Indian e-commerce firms like Flipkart streamline order-to-delivery steps to cut cycle time. Improved processes reduce cost, shorten lead time, and raise productivity. Continuous improvement becomes easier because each process can be measured against clear performance targets.

6. Enhances Customer Satisfaction

Customers experience the supply chain through order, delivery, and service processes. Viewing the chain as processes keeps attention on what the customer actually receives, such as accuracy, speed, and reliability. For example, Amazon designs its order fulfilment and returns processes around fast, dependable delivery. Well-managed processes improve on-time delivery, order accuracy, and responsiveness. This builds customer loyalty and gives the firm a competitive edge in domestic and international markets.

7. Aligns Supply Chain with Business Strategy

The process view helps match supply chain processes to the firm’s competitive strategy, whether cost leadership or responsiveness. A firm competing on low cost may favour push processes with economies of scale, while one competing on customisation may favour pull processes. For example, Zara uses quick-response processes to support its fast-fashion strategy, while commodity producers emphasise efficiency. This alignment ensures that process design supports strategic fit and long-term goals.

8. Facilitates Integration and Technology Use

Clearly defined processes make it easier to integrate systems such as ERP, EDI, and tracking platforms across partners. Technology works best when it supports well-designed processes, not confused ones. For example, SAP implementations typically begin by mapping and standardising business processes. Integration improves information sharing, reduces manual errors, and speeds up transactions. It also gives real-time visibility across international operations.

9. Helps Manage Risk and Uncertainty

Process mapping highlights critical dependencies, single points of failure, and areas of high uncertainty. Managers can then build buffers, backup suppliers, and contingency plans where needed. For example, after pandemic disruptions, many firms revisited sourcing and logistics processes to add resilience. Understanding which processes are push-based and forecast-driven also shows where demand errors are most likely. This supports proactive risk management and quicker recovery from disruptions.

Cycle View of Supply Chain:

The Cycle view divides the supply chain into a series of cycles, each performed at the interface between two successive stages. Every cycle begins with an order placed by the customer stage and ends with delivery by the supplier stage. The four main cycles are the customer order cycle, replenishment cycle, manufacturing cycle, and procurement cycle. Each has defined activities, owners, and timings, so managers can see who initiates and who fulfils each step. For example, Walmart’s replenishment cycle with Procter & Gamble is triggered by store sales, while Dell’s manufacturing cycle starts after a customer order. This view clarifies responsibilities and supports operational planning.

Stages in Cycle View:

1. Customer Order Cycle

The customer order cycle occurs at the interface between the customer and the retailer. It starts when the customer arrives or places an order and ends when the customer receives the product. Key processes are customer arrival, order entry, order fulfilment, and order receiving. The retailer owns this cycle and aims to fill orders quickly and accurately. For example, on Amazon India, a customer orders a phone, the system confirms stock, and the item is packed and delivered. This cycle is demand-driven and directly shapes customer satisfaction, since delays or errors are felt immediately.

2. Replenishment Cycle

The replenishment cycle occurs between the retailer and the distributor or wholesaler. It begins when the retailer’s stock falls to a reorder point and ends when the retailer receives fresh inventory. Processes include retail order trigger, order entry, order fulfilment, and order receiving. The retailer initiates it, and the distributor fulfils it. For example, Walmart’s stores reorder from P&G or a distribution centre based on sales data. Good planning balances inventory cost with product availability, and this cycle is often forecast-driven, so demand errors can cause stockouts or excess stock.

3. Manufacturing Cycle

The manufacturing cycle occurs between the distributor or retailer and the manufacturer. It starts when orders arrive from the downstream stage, or when inventory is projected to fall short, and ends when finished goods are delivered. Processes include order arrival, production scheduling, manufacturing and shipping, and order receiving at the distributor. The manufacturer owns it. For example, Hindustan Unilever produces soaps in batches based on distributor orders and forecasts, while Dell assembles only after receiving customer orders. The cycle may be pull or push and depends on production capacity and lead time.

4. Procurement Cycle

The procurement cycle occurs between the manufacturer and its suppliers. It begins when the manufacturer needs raw materials or components and ends when the supplier delivers them. Processes include supplier selection, order placement, supplier production, delivery, and receiving. The manufacturer initiates it and the supplier fulfils it. For example, Tata Motors orders steel, electronics, and tyres from suppliers based on its production plan. Since component needs are known from the manufacturing schedule, this cycle is largely planned. Efficient procurement ensures continuity of supply, controls cost, and prevents production delays, which is especially important in international chains with long lead times.

Features of Cycle View:

1. Division into Distinct Cycles

The cycle view splits the supply chain into separate cycles, each at the interface between two successive stages: customer order, replenishment, manufacturing, and procurement. Every cycle has its own start point, end point, and set of activities. This makes a complex chain easier to analyse and manage one segment at a time. For example, a retailer like Reliance Retail can study its replenishment cycle with distributors independently from its customer order cycle. This modular structure helps managers pinpoint where delays or errors arise.

2. Customer-Initiated Flow

Every cycle begins with an order placed by the customer stage and ends with delivery by the supplier stage. Demand therefore flows upstream as orders, while products flow downstream. This keeps the chain focused on customer demand rather than internal convenience. For example, when a shopper buys a phone on Flipkart, the sale triggers replenishment, which in turn triggers manufacturing and procurement. This feature clarifies the direction of order and material flow across all stages.

3. Clear Ownership and Responsibility

Each cycle has a defined initiator (the customer stage placing the order) and a fulfiller (the supplier stage delivering it). Responsibilities for order entry, fulfilment, and receiving are explicit. For example, in the procurement cycle, Tata Motors places orders and its tier-1 suppliers deliver parts. Clear ownership reduces overlap and confusion, improves accountability, and helps in setting performance targets for each party, especially in international chains involving many organisations.

4. Operational and Detailed Focus

The cycle view is highly useful for operational decision-making. It specifies activities such as order entry, order fulfilment, production scheduling, and receiving, along with their timings. Managers can estimate cycle times, plan capacity, and set inventory levels based on these details. For example, a firm can calculate how long procurement from an overseas supplier takes and adjust safety stock accordingly. This detail supports day-to-day execution and process control.

5. Sequential and Interlinked Structure

The cycles are linked in sequence, with the output of one triggering the next. A customer order cycle leads to a replenishment cycle, then manufacturing and procurement. Delays or errors in one cycle ripple through the others. For example, a supplier delay in the procurement cycle can halt production and leave retailers out of stock. Recognising this interdependence encourages coordination and end-to-end planning across partners.

6. Flexibility in Chain Structure

The number and type of cycles can be adapted to the firm’s supply chain. A direct-selling firm like Dell may skip the retailer and distributor cycles, while a multi-tier chain may include additional cycles. The framework applies to manufacturing, retail, and service supply chains alike. This flexibility makes the cycle view useful for different industries and for both domestic and international chains.

7. Basis for Performance Measurement

Because each cycle has defined start and end points, firms can measure cycle time, order accuracy, fill rate, and cost for each one. This helps identify weak links and set improvement targets. For example, an Indian e-commerce firm can track its order-to-delivery time in the customer order cycle. Such measurable metrics support continuous improvement and benchmarking against competitors.

Push-Pull View of Supply Chain:

The Push-Pull View of Supply Chain classifies supply chain activities according to whether they are performed in anticipation of customer demand or in response to actual demand. Push processes are based on demand forecasts, where products are manufactured and distributed before receiving customer orders. Pull processes begin when actual customer orders are received, and activities are performed to fulfil those orders. The point separating these processes is called the push-pull boundary. In international supply chains, this approach helps balance inventory costs, production efficiency, and customer responsiveness. For example, a company may manufacture standard products in advance but customize them after receiving orders.

Characteristics of Push-Pull View:

1. Classification by Demand Trigger

The push-pull view classifies every supply chain process by what triggers it. Push processes start in anticipation of customer orders and rely on forecasts, while pull processes start in response to actual orders. This gives managers a simple test for each activity: is it driven by prediction or by real demand? For example, a Hindustan Unilever factory building detergent stock is push, while a customer ordering a custom laptop from Dell triggers pull. The classification makes the nature of each process clear.

2. Existence of a Push-Pull Boundary

Every supply chain has a push-pull boundary (decoupling point) that separates push stages from pull stages. Processes upstream of the boundary follow forecasts, and those downstream follow real orders. The view therefore treats the chain as a mix of both, not purely one or the other. For example, Dell’s component sourcing is push, while assembly after a customer order is pull. The boundary’s position is a key strategic decision that shapes inventory, lead time, and cost.

3. Strategic and Planning Orientation

The push-pull view is more strategic than the cycle view. It guides decisions on inventory levels, capacity, and flexibility rather than day-to-day execution. Managers use it to decide where to hold stock and how responsive the chain should be. For example, a firm entering a volatile market may shift its boundary toward pull to avoid unsold goods. This makes the view valuable for long-term planning and supply chain design, particularly in international chains with long lead times.

4. Link with Demand Uncertainty

The view is closely tied to demand uncertainty. Push processes face high uncertainty because they depend on forecasts, so errors cause excess stock or shortages. Pull processes face lower uncertainty since they respond to known orders. For example, fashion and smartphone makers with unpredictable demand rely more on pull, while staples like salt or cooking oil suit push. Recognising this link helps firms reduce the bullwhip effect and manage forecast risk.

5. Trade-off Between Efficiency and Responsiveness

Push processes favour economies of scale, lower unit cost, and shorter customer waiting time, but risk obsolescence. Pull processes favour responsiveness, customisation, and low inventory, but need flexible capacity and give longer delivery times. The view highlights this trade-off so firms can choose the right balance. For example, Zara pushes design and fabric purchasing but pulls garment production based on store sales, balancing cost and speed.

6. Different Management Requirements

Push and pull processes need different management styles. Push processes require strong forecasting, aggregate planning, and inventory control. Pull processes require flexibility, fast information flow, short setup times, and responsive suppliers. For example, a make-to-stock firm invests in demand forecasting tools, while a make-to-order firm invests in quick changeovers and real-time order tracking. Matching management practices to process type improves efficiency and service.

7. Applicability Across Industries

The view applies to manufacturing, retail, and service chains alike, and to both domestic and international operations. Different products within one firm may sit at different boundary positions. For example, a car maker may push standard models to dealers while building premium variants to order. Strategies such as make-to-stock, assemble-to-order, and make-to-order all fit within this framework, which makes it a flexible tool for comparing supply chain designs.
