Traditional clothes retailers do their business through 4 major stages in sequence before the clothes reach the market window. They are mainly the design, sourcing, external manufacturing, internal manufacturing and distribution processes. The whole cycle from design to market will usually take 6 months, and by the time they reach the market, if they have not missed profitable window, the demand would have changed leading to a miss-match of supply and demand. Zara’s story of market success is quite unique. They completely abandoned the “sequential model” and adopted a “concurrent model”. They re-configured their supply chain and re-engineered those processes concurrently. That is 40% of design; 60% of external manufacturing, and 80% of internal manufacturing and nearly 100% of distribution are done within the profit/market window. This supply chain model significantly shortened the design to market cycle from 6 months to 6 weeks, and be able to respond to the market demand change much more swiftly to lead the fashion rather than betting on them. The shortened supply chain has also significantly reduced overall stock throughout the chain leading to more competitive cost. Zara has thus provided a world class showcase for agile supply chain.
