In an era where fashion companies are struggling to monetize their data effectively, leading firms are leveraging data and analytics to gain market share and create lasting value. This article explores how data-driven approaches are revolutionizing fashion design and business operations.
The Data Revolution in Fashion
The fashion industry has experienced a dramatic shift in how data is utilized for value creation. According to McKinsey & Company, the COVID-19 crisis exposed major shortfalls in data gathering and analysis across much of the industry, creating a widening gap between data leaders and laggards. The 25 top-performing retailers—most of which epitomize the powerful shift to digital, data, and analytics—represent more than 90 percent of the sector's increase in global market capitalization during the pandemic.
Simply put, the sooner fashion and luxury companies learn to harness the power of data, the better positioned they are for success in an increasingly competitive market.
Data Gold Mines Across the Value Chain
Data is more abundant than ever, and fashion companies that are likely to emerge stronger from market challenges are tapping into their data to stay ahead. The use cases for data and analytics are varied and numerous, but the challenge often lies in pinpointing where and how to integrate data into the business in a cross-functional way.
Fashion and luxury companies that have integrated data into their planning, merchandising, and supply-chain processes have seen tangible results. Data-driven decisions around stock and store optimization have increased sales by 10 percent, while enhancing visibility throughout the supply chain has streamlined inventory management and reduced inventory costs by up to 15 percent.
Personalization: The Key to Digital Growth
Most significantly, fashion companies that have harnessed the power of data to personalize customer e-commerce experiences have grown digital sales by between 30 and 50 percent. This represents one of the most impactful applications of data-driven approaches in the fashion industry.
Building personalized interactions with customers across multiple channels has led to a 20 percent increase in revenue, and companies that have used data to optimize pricing have also been able to increase margins by up to 10 percent. This demonstrates the critical importance of data-driven personalization in modern fashion retail.
Four Pillars for Building Data Capabilities
1. Strategy and Use-Case Battlegrounds
The data journey starts with setting a vision for how data will support business goals over the next two to four years. This vision-setting process is best led by a chief data officer (CDO), someone senior in the organization who can champion the change through competing business priorities. The CDO translates that vision into a set of core priority business domains—the company's data and analytics "battlegrounds"—and defines specific use cases for each priority domain.
Customer personalization should be on every fashion player's data and analytics roadmap, as this is table stakes today. Leading sports-apparel retailers have developed ambitious data visions to power one-to-one relationships with consumers through data-driven personalized experiences, collecting huge volumes of data from customer-facing apps to offer more targeted experiences.
2. Data Architecture and Platforms
Modern fashion data architectures handle core retail day-to-day datasets that are large and unstructured, such as SKUs, sales, point-of-sale transactions, stock transactions, e-commerce touchpoints, customer 360 information, and RFID data. Most fashion and luxury companies have expensive legacy systems built on inflexible, nonscalable data warehouses that cannot integrate new data sources.
Leading fashion players have built new data architectures with massive multilayer data lakes in private clouds, consolidating hundreds of internal and external data repositories. These investments have enabled processing power of several petabytes of data per hour, allowing rapid response to market changes and the capacity to identify trending products earlier than competitors.
3. Governance and Operating Model
Data management is often the Achilles' heel of many fashion and luxury companies. The absence of high-quality data and clean taxonomies, and the general lack of common language around data across the organization, wreaks havoc when starting on an analytics journey. Fashion companies have tackled this by setting up value-backed data-operating-model frameworks across 20 to 30 data domains that have clear owners in each business unit.
A leading integrated omnichannel fast-fashion player achieved a 50 percent improvement in data quality by defining a data-governance framework including roles, responsibilities, and processes. The firm set up teams responsible for developing tools and use cases while also defining and integrating data governance.
4. Talent and Culture
Many fashion and luxury companies have taken the leap of upskilling their workforces and reinventing talent and culture practices. Leading businesses have found success with data academies to train new data professionals and ensure that core decision makers can translate data and analytics to fit business needs. A data culture that not only accepts data-driven insights but is hungry for them is critical to get value from data investment.
Real-World Success Stories
In March 2020, when stores across the United States closed overnight and sales plummeted by 80 percent, a leading fast-fashion player was sitting on inventory locked in store back rooms. The firm had a few months of runway and was facing bankruptcy.
Fast on their feet, executives created three cross-functional teams to accelerate one-to-one personalized marketing, launch ship-from-store, and mine merchandising insights using rich data from their online channel. In weeks, the firm was operating fundamentally differently—testing and learning, driving data-backed actions, and making decisions as a cohesive unit.
By the end of 2020, the business was picking up market share for the first time in ten years. The firm's leap into data and analytics set it on a course of transformation, creating cross-functional teams across all major steps in the value chain.
The Path Forward: A Four-Phase Approach
Fashion and luxury companies seeking to extract value from data can implement a sustained campaign in four phases:
- North Star Definition Phase: Define the vision, priority domains, and key battlegrounds across the value chain. This phase typically lasts six to ten weeks.
- Value Creation Phase: Start generating value through two or three quick-win use cases while migrating data to new architecture and setting up governance. This phase lasts four to six months.
- Scale Phase: Scale the transformation to tens of use cases in parallel, with three- to four-month development cycles. This phase lasts six to nine months.
- Transformation Phase: Fully embed data and analytics within the company value-creation machine, with hundreds of use cases in production.
Future Outlook
The initial leap into data should not be daunting for fashion and luxury companies; many have proven the investment worthwhile. Investment in data and analytics could pay for itself—the upfront cash investment can be scaled as value is created. The sooner fashion and luxury companies leap in, the better positioned they are for long-term success.
As the industry continues to evolve, companies that successfully harness the power of data to build stronger relationships with customers and drive operational efficiencies will be well-positioned to thrive in an increasingly competitive and technologically advanced landscape.
