2 Business description

A large supermarket chain has over 100 stores across the country. Each store is made up of several  departments: greengrocery, frozen foods, general grocery, dairy, meat, delicatessen, bakery and  health/beauty. Each store has approximately 100,000 products on its shelves. Individual products are  known as stock keeping units (SKUs). The SKU numbers are placed on these products using scannable  labels and become the product’s bar code.

About 90,000 of the SKUs come from outside suppliers/manufacturers and have bar codes imprinted  on their packaging. 

There are two main locations for business operations within the stores. The first of these is at the cash  registers where customers pay for their purchases. The shop assistant scans the product bar codes into  the Point Of Sale (POS) system to process the sales transactions. 

The supermarket sells products online and in local stores.

With online purchases, customers must register online to have a valid credit card and contact information.  The supermarket web service provides the groceries catalogue and shopping cart. Customers can choose  groceries adding to the shopping cart one by one. Once the requested groceries/products and a credit card  are validated, the order records are issued to customers. The local stores’ sales staff will provide the  services to PACK and check the ordered groceries according to the requested time by the customer, so  they’re ready for customers to pick up to suit customers need. The online orders may ask to deliver  customers’ purchases to their homes. The delivery team needs to work out the delivery efficiently.

The second location of the business activities is at the back door where runs the supply chain to support  the products of the supermarket. The supermarket manager is concerned with the logistics of procurement  transactions and selling products while maximising profit. 

Procurement is a critical business activity. Effective procurement of products at the right resale price is  obviously important to retailers and distributors. Procurement also has strong bottom-line implications  for any organization that purchase products from suppliers and manufacturers. Procurement officers need  to perform a wide range of activities from negotiating contracts to issuing purchase orders; from shipping

notifications to delivery; from warehousing to tracking receipts and authorizing payments. Significant  cost savings opportunities are associated with reducing the number of suppliers and negotiating  agreements with preferred suppliers. The procurement management is frequently checking those most  frequently purchased products and identifying opportunities to negotiate favourable pricing by  consolidating suppliers for single sourcing.

Each store requires to have inventory management. The store managers keep their inventory records and  maintain their inventory at a good level. Efficient inventory management is driven by demand planning.  After the demand is forecasted and the inventory at a low level, the managers order the products and  trace the deliveries from the supermarket warehouse. The inventory’s goal is to obtain the appropriate  quantity of products in the most economical manner. 

Profits are obtained by charging the maximum possible for each product while keeping costs associated  with acquisition and other overheads as low as possible. The supermarket finance manager will monitor  the performance of their business operations and allow the business analysis.

To ensure high customer numbers, management needs to carefully consider its pricing and promotions. Promotions include temporary price reductions, newspapers and other media ads, store displays and  catalogues on store web online weekly. Heavy price reductions are the most effective way to create  substantial increases in the number of products sold. As a result, the visibility of all forms of promotion  is an important part of analysing the business operations of the supermarket.

The supermarket chain has implemented a Frequent Shopper Program to attract loyal customers. The  shoppers can register online or at a local store to receive the frequent shoppers’ cards. They can collect  the points with their membership card for purchases at any store by scanning their frequent shoppers’ cards. More purchases can get more points to obtain more membership benefits. The customer  relationship management sends the membership letters monthly and handles customer's complaints and  other issues related to customers.

The supermarket finance department needs to process financial related transactions including paying out to suppliers for procurement transactions, collecting receivables, calculating profile of promotion,  preparing the regular report of profit & loss to management analysis and decision markings.

The supermarket management wants to gain a better understanding of customer buying habits. Managers  want to analyse what products are selling in which stores under what promotional conditions and whether  customers preferred shopping style is at a local store or online shopping. Therefore, an integrated  information system is indispensable to the success of the supermarket.
