Push and Pull Supply Chain Factors

Understanding Strategic Fit

Strategic fit refers to the alignment between the competitive strategy of a company and its supply chain strategy (Contador et al., 2021). It involves ensuring that the capabilities and processes of the supply chain can support and complement the overall business strategy. The goal is to create a seamless integration where each component of the supply chain enhances the other, which should contribute to the competitive advantage and profitability of the company. A strategic fit enables the company to be more efficient in terms of managing costs, ensuring customer satisfaction, and staying ahead of competitors.

Push/Pull Processes

The concepts of push and pull in supply chain management refer to the underlying operational processes. Push processes are also known as "make to stock," and involve producing goods based on demand forecasts before actual purchase orders from customers are received (Van Donk, 2001). With this approach, the risk of overproduction or stock-outs is managed through accurate demand forecasting. Pull processes, on the other hand, are known as "make to order," and involve producing goods only after receiving a customer's order (Van Donk, 2001). This approach reduces the risk of overproduction but requires a responsive and flexible production process to meet customer demands quickly.

A combination of push and pull processes is typically used in a push-pull boundary or decoupling point. It is an approach in which push processes for the upstream supply chain and pull processes for the downstream supply chain are implemented so as to capitalize on the advantages of both strategies.

Decision Phases in a Supply Chain

There are three major decision phases in a supply chain: design, planning, and operation. Design involves making decisions about the structure of the supply chain and product design, which have long-term implications. Decisions are based on predicted market conditions over the next few years. Planning involves applying the parameters decided in the design phase to optimize decisions for expected market conditions over the next quarter or year. The operation phase involves making short-term decisions. These decisions are much more responsive to the immediate market demands and aim to handle daily and weekly operational concerns.

Agile Supply Chains

An agile supply chain is one that is extremely flexible and responsive to changes in demand and supply (Christopher et al., 2004). It prioritizes speed and adaptability, allowing the company to respond to unpredictable market changes efficiently. Agile supply chains use advanced data analytics for real-time visibility and quick decision-making, ensuring that the right product reaches the right customer at the right time.

Role of Uncertainty in Global Supply Chains

Uncertainty in global supply chains can arise from various sources such as demand variability, lead time variability, supply disruptions, and exchange rate fluctuations. This uncertainty is a challenge because it makes planning more difficult and can lead to inefficiencies in the supply chain. However, it is also an opportunity because managing uncertainty effectively can lead to a competitive advantage. Companies that can design their supply chains to be resilient to these uncertainties can maintain their operations smoothly even in the face of disruptions.

To ensure strategic fit, a company must first clearly define its competitive strategy and understand its customers' needs. The supply chain strategy must then be designed to support this competitive strategy. For example, if the competitive strategy is to provide a wide range of products quickly, the supply chain should be designed for high responsiveness, which might involve an agile approach and pull processes. The company must also understand the level of implied uncertainty in its supply chain (from demand and supply variations), and align its supply chain capabilities to handle this uncertainty. This involves making trade-offs between responsiveness and efficiency based on the level of uncertainty. Lastly, the strategic fit should be reviewed and adjusted over time as market conditions, customer needs, and supply capabilities change.
