\u201cThrough the artificial intelligence algorithm, our forecasts are constantly improving. This way, we get precise results that help us plan and control a future-oriented product range.\u201d<\/em>1\u00a0<\/sup>Mathias St\u00fcben, Director Category Processes, OTTO<\/p>\n

With the proliferation of online shopping data, the advances in data science and the ease of access to machine learning solutions, the e-commerce landscape is rapidly changing2<\/sup>. With \u20ac3.0bn of sales, OTTO is Germany\u2019s second largest e-commerce retailers behind Amazon (\u20ac8.8bn) and ahead of Zalando (\u20ac1.3bn)3<\/sup>. The company is predominately active in the highly seasonal fashion and electronics retailing categories and offers 2.2M SKUs, approximately 50% of which are sourced from brand partners.<\/p>\n

In a highly competitive e-commerce environment with increasing cost pressures4 <\/sup>and customers expecting OTTO\u2019s own and partner-branded products to be available immediately, how can OTTO offer fast product delivery while ensuring that its inventory levels are minimized and no stock is left at the end of the season?<\/p>\n

Autonomous Product Replenishment through Machine Learning<\/strong><\/p>\n

In order to balance product availability and inventory levels, OTTO has begun to utilize the machine learning algorithms of Blue Yonder, a data science and machine learning company it helped back and whose algorithms originally stem from elementary particle experiments at the CERN laboratory in Geneva5<\/sup>.<\/p>\n

The algorithms use hundreds of different input variables including internal data (historical sales, traffic and searches, buy\/no buy decisions, placement on website, location-based parameters) and external data (competitor data, weather forecasts, day of the week and public holidays) to predict precise SKU-level sales forecasts on a daily basis1, 6<\/sup>.<\/p>\n

OTTO\u2019s daily product replenishment function for partner-branded products, traditionally performed by humans based on data, intuition, and domain knowledge7<\/sup>\u00a0, is now driven by the algorithm. As a result, the application has allowed OTTO to predict with 90% accuracy on any given day what items will be sold over the next 30 days and reduce inventory levels by 20%5<\/sup>.<\/p>\n

While competitors such as Amazon have deployed machine learning predominantly to inform its customer recommendation engine, OTTO is already advancing the use of machine learning by adopting a fully autonomous and data driven replenishment function5<\/sup>.<\/p>\n

Recommendations for OTTO\u2019s Management<\/strong><\/p>\n

Initially, I believe OTTO should drive further cost-savings across a range of tasks including autonomous staffing plans in distribution centers based on sales forecasts and transportation cost reductions through pre-arranged shipments based on expected customer demand. Moreover, OTTO should expand the application of its machine learning algorithm from its fashion and electronics products to its furniture and home wares portfolio as these products carry higher inventory costs.<\/p>\n

Over the medium term, OTTO should seek to expand machine learning across their entire business from product development and manufacturing through to supply chain management and customer engagement. For example, machine learning algorithms should help OTTO advance their product catalogue by identifying trends in social media, customer behavior and transaction data. These unique insights will help OTTO differentiate its own product development from CPGs who are further upstream in the supply chain and do not have full order visibility. Moreover, the company should leverage its daily rolling customer demand forecast in its production process to build products by size and color \u201cjust-in-demand\u201d. Also, the algorithms will re-shape OTTO\u2019s supply chain configuration and decision making as long-term sales forecasts will drive the placement of its distributions centers. Finally, machine learning algorithms will enable OTTO to develop a total view of the customer, which will enable it to build deeper relationships and improve customer engagement and loyalty.<\/p>\n

Considerations<\/strong><\/p>\n

OTTO is advancing the use of machine learning in its operations, a move that is seen as extremely unusual by industry experts5<\/sup> and that will have sparked intense internal debates, particularly as a meaningful portion of the retailer’s staff is employed in merchandising and replenishment functions. With its radical shift to autonomous decision-making, how can OTTO avoid technology fear\u00a0among employees and stakeholders and build a culture that embraces technology-led innovation8<\/sup>?<\/p>\n

Moreover, although Blue Yonder\u2019s machine learning and OTTO\u2019s autonomous deployment of the algorithms are currently serving as a competitive advantage, how sustainable is that advantage when other retailers replace core functions with machine learning algorithms? How would a world look like in which product assortment, pricing and customer experience across retailers are driven by the same algorithms?<\/p>\n
