Problem: Customer Expectations are changing faster than traditional planning

Shoppers are increasingly looking for instant gratification. They want products faster and with a personalized shopping experience. Their expectations are forcing retailers to rethink strategies and tune up execution.


Through the internet, all offers have become more transparent and at the same time demand and preferences from consumers become more volatile. Today’s consumers have more information at their fingertips than ever before: The ability to compare services and prices online and easily order from different providers, even across long distances, decreases the loyalty and the stability of your customer base. At the same time, for a company it gets easier than before to attract new customers with the right offer.


In this volatile environment, managing and optimizing category structure and inventory depends more and more on understanding the expectation of consumers, the changing market trends and the total sales potential. Purchasing and inventory planning which cannot respond to these trends fast enough will face higher risk such as of selling out on the attractive products and remaining with overstock for less attractive products.


Solution: incuda’s approach - how incuda helps to respond faster to the market

We help Category Managers with an enhanced version of the “Renner Penner” (Magic Quadrant) analysis.


The traditional analysis is based on orders and revenues, and groups the products into four quadrants according to sales and order count. This approach is focused on order data and the Category managers has no information about all the visitors who does not buy. Similar analyses could be available from Web-analytics tools, there you can see the visitor’s navigation and view events, but these tools do not have information on cancellation, returns, or profit metrics.


The incuda “Renner Penner” analysis adds information about customer “interest” to the order data, especially if visitors look at products or put them in the shopping basket. The order event is a crucial step but following this we track cancellations and returns, and can report on profit metrics. Information on stock level and data aggregation on brand or category level are a few additional features of the analysis.


The first chart below shows the raw data of product interest (X axis = number of product view events) and the conversion probability (Y axis = number of orders by number of view events). The size of the bubbles represent the total revenue generated by the products.


The raw data in the “Renner Penner” analysis:

The raw data shows strong clusters of products and big empty spaces. To improve the usability of the analysis, we normalize the data by normalizing outliers and grouping the products into four quadrants. The Matrix is divided into four quadrants based on an analysis of View Events and Order Conversion, as shown in the first diagram below.


The normalized “Renner Penner” chart - Short description and ideas for the interpretation of our quadrants:


They generate high interest (many view events) and show a high order conversion. These are the products which are very attractive, and you sell a lot, they generate a high amount of total revenue (maybe you call them your “A” products).


Recommendation: check which of these products have a high/low profit margin. If you own the brand or have a special agreement with the manufacturer you might have high margins. If it is a highly attractive product from an established brand and available from many retailers (“commodity”), margin might be low.



These products are viewed often by your visitors. They are considered “interesting”, but for some reason, people don’t buy them.


Recommendation: in the traditional “Renner Penner” analysis these products would be considered unattractive as they generate low sales numbers and at the same time they often have higher prices, so even putting the products on stock is expensive.


The low conversion rate might depend on different reasons:

- If the price is unattractive compared to the competitors or delivery time too long, you might try to improve here.

- If the price level is high (luxury product), then use the product for traffic acquisition and branding: you can plan with lock stock levels. However, showing these products to the market brings you visitors at lower cost and gives you a high-value perception as a retailer. You should take care to navigate these visitors from the hype-pages to other, more affordable products which they are able or willing to buy.



Visitors are rarely interested in these products, and even if they look at the products the probability of purchase is low. With the traditional “Renner Penner” you might consider removing these products from your offering. With the incuda's approach you can follow a long-tail approach.


Recommendation: incuda's “Renner Penner” provides you the link from the order and view events to the visitors. This allows you to segment users and products (with higher margins) and use a personalized approach to show a relevant selection out of a wide range of products to many single visitors. With the higher relevance per user and the increased conversion, you create new sales opportunities, probably in a lower-competitive market segment (few retailers can handle long-tail strategies).


Hidden Champions:

Few people look at these products, but many of them are buying the product. The general approach is to grow these products into the “Renner” quadrant.


Recommendation: Check which part of these hidden champions are products which are “demand-driven”, e.g. food or consumable products. You might offer special services or implement push campaigns to remind customers and create repeat purchases.


To identify potential “Winners”, link the data to “early mover” visitors and customers who buy upcoming top products early on and get a short-list of products which should be pro-actively marketed to a wider audience.
