Each store has a local operational database to capture their day-to-day business processes such as POS transactions and backend inventory. Each store records the following data in their database:

A receipt file containing all the individual receipts for their sales of products.

At end of the day, the inventory level need to checked, new order may be made by the management at local stores.

 

Promotion is one important activity to improve the business. Promotions include temporary price reductions, newspaper and other media ads, store displays and coupons. Heavy price reductions are the most effective way to create substantial increases in the number of products sold.

The promotions can be decided centrally or locally, depending on the cases. Each promotion is specified with a promotion_id and the description. It is then the responsibility of the store manager to apply promotions during the sales activities. Promotion files contain information about the different promotions.

  • the promotion describes its scope (which products are affected) such as:
  • a list of specific products and their brand
  • a specific category of products
  • the types of customers may benefit from it (eg., all customers or a specific class (Gold and Platinum)).
  • Start and end dates (that is, for seasonal promotions
  • Discount level

 

The central management is looking for determining whether the promotion was effective:

The need to analyze sales revenue that includes the promotions were applied for the production sales.  The sale records contain information about which promotion affected the actual price of the product item.

In order to compute the effectiveness of the promotion, several factors have to be considered:

  • The total cost of the promotion

The sale revenues generated for the targeted products (lift)

  • The impact on revenues for other products within the same category during that same period (cannibalization and/or upsell)
  • Whether the products under promotion experienced an increase during the promotional period?
  • Whether the products under promotion showed a drop on sale just prior to or after the promotion thereby canceling any gain
  • Whether the promotion was profitable?
  • Which stores have more sales during the promotions? Does this vary across different months or event types?
  • What products were on promotion but did not sell?

 

The central management at HQ maintains the supply chains running smoothly and efficiently. The procurement management seeks the significant cost savings opportunities, and negotiates agreements with preferred suppliers. Procurement’s goal is to source the appropriate products in the most economical manner. Procurement involves a wide range of activities from negotiating contracts to issuing purchase requisitions and purchase orders (POs)to tracking receipts and authorizing payments. Some of common analytic requirements are listed as follows:

  • Which products and what brands are most frequently purchased by customers in recent month? How many vendors supply these products? At what prices?
  • Looking at demand across all stores, are there opportunities to negotiate favorable pricing by consolidating supplier?
  • Are you receiving the negotiated pricing from your supplier or is there supplier contract purchase price variance?
  • How are your vendors performing? What is the supplier’s fill rate? On-time delivery performance? Late deliveries outstanding? Percent back ordered?

 

The order management is composed of a series of business activities. Each order needs is associated with an order date, requested ship date, product, sales rep, and deal.  A deal is an agreement between Chemist Warehouse group and supplier for their goods related discount during a fixed period. Chemist Warehouse objective is to enhance the customers healthcare outcome via the most effective and efficient means, resulting in great savings to the end user.

 

Every week, HQ distributes a central list to all stores with available products from the different suppliers, including price, availability information, the ratings and categories of products for dispatching.

 

The revenue of the business is generated by POS including preparing medications. Retail price may vary between sessions, promotion periods or special events.  The central management collects all local store’s weekly sales and product inventory information for data analysis, demand forecasting, and decision making. The management needs to analyse the income from different types of product for purchase decisions. They also need data for their expansion plan. Marketing managers need to analysis customer behaviors and location performance for better planning and promotion decisions.

 

The central management wishes to perform detailed analysis of their business performance efficiently and effectively and has decided that a simple reporting feature built on top of their operational database will not be adequate. Not only will it compromise the efficiency of their operational database, they also wish to incorporate their flat file data into their analysis.

1.What category and brand of products are the most popular in this year? Has this always been the case or has there been a shift in recent years?

 

2.Are there certain times of the year when more products are sold? Which days of the week more products sold?

9.Does the promotion activity provide the benefits to the business?

 

10.The promotion period in Christmas month has increased the sales comparing with the same period in last year?
