Chapter 5 · Zara, retail information systems, and supply chain coordination
Vocabulary
Bullwhip Effect
The bullwhip effect is the problem where small changes in consumer demand cause much larger swings in orders and inventory as those signals move backward through the supply chain. The farther a firm is from real customer demand, the more likely it is to overreact. Better information systems reduce this by giving more partners access to timely sales and inventory data.

Core Competency
A core competency is a capability a firm performs especially well and can use to create lasting advantage over rivals. In Zara’s case, the key competency is not just making clothes. It is coordinating design, production, logistics, and store data quickly enough to respond to fashion demand faster than competitors.

Disintermediation
Disintermediation happens when a firm removes an intermediary from the value chain and deals more directly with customers or suppliers. This can lower cost, speed up information flow, and improve control, but it can also shift more operational burden back onto the firm.

Distributor
A distributor is an intermediary that moves products from producers to retailers or other buyers. Distributors can add value through scale, warehousing, transportation, and market access, but they can also slow information flow and reduce a firm’s direct control over demand signals and customer relationships.

Logistics
Logistics is the planning and execution involved in moving goods efficiently through the supply chain, including transportation, warehousing, replenishment, and delivery timing. Strong logistics matter because a firm can only turn data into competitive advantage if it can physically move products fast enough to act on what the data reveals.

Omnichannel
Omnichannel means a firm coordinates customer experience across physical stores, websites, mobile apps, and other channels so they work together instead of operating as isolated silos. The goal is not just to be present in many channels, but to make inventory, customer information, and buying experience flow smoothly across them.

Point-of-Sale (POS) System
A point-of-sale system is the combination of hardware and software used to record sales transactions and often track inventory, pricing, and store activity in real time. Zara’s kind of model depends on POS data because managers need to know what is actually selling right now, not just what was shipped to a store weeks earlier.

RFID
RFID, or radio-frequency identification, uses small tags and readers to identify and track items wirelessly. In retail and supply chains, RFID improves inventory visibility, makes counting faster, and helps firms know where products are without manually scanning each one. That speed can make replenishment and omnichannel fulfillment more accurate.

Vertical Integration
Vertical integration means a firm owns or tightly controls multiple stages of its value chain instead of outsourcing them all to outside partners. Zara’s system is powerful because it keeps design, production, and distribution closely linked, but that same tight integration can also create concentration risk if something in the system breaks.

Fast Fashion from slides
Fast fashion is a business model built around quickly translating emerging trends into products that reach stores in short cycles. Information systems are central to this model because trend detection, store feedback, inventory data, and rapid coordination all have to move faster than in traditional apparel systems.

Inventory Visibility from slides
Inventory visibility is the ability to know what inventory exists, where it is, and how quickly it is moving across the supply chain. High visibility helps firms reduce stockouts, avoid overproduction, and support omnichannel promises such as buy online and pick up in store.

Fair Factories Clearinghouse from slides
The Fair Factories Clearinghouse was an information-sharing initiative that allowed participating firms to collaborate on factory audit information and reduce duplicated effort in monitoring labor and ethical compliance. It matters in MIS because it shows how information systems can improve transparency and coordination for social responsibility, not just profit and speed.
