Part 1

Company Description & Strategic Planning Factors

Playball! Inc. is retail company that specializes in sports equipment, clothing, books as well as

videos for baseball, basketball, football, soccer, and Gulf. Playball! Currently has over 48,000

customers with a projected growth rate of about 10% per year during the next two years. By

2008, PlayBall! had an inventory of over 1,000 products with the number of products growing

18% since 2007. The inventory is expected to grow 14% over the next two years. Customer

satisfaction is extremely important for Playball! and its customers. With that being said, rapid

shipment of orders and efficient management are a particularly high-priority concern. Although

efficient inventory management has kept back-orders to a minimum, Playball! wants to further

reduce back-orders and advance order fulfillment rates. In addition, due to Playball!’s liberal

return policy of defective products and products that do not meet customer satisfaction, Playball!

would like to minimize the number of returns by reducing defects and by providing a detailed

description of their products to its customers.

As Is Business Process Flow

Key Problems

● Product information can be hard to locate if customer does not know product code

● No way to track vendor quality

● No way to analyze customer information

● No inventory report, sales, or commission reports

● Cannot track sales performance of individual customer representatives

● Repetitive steps in ordering process

Proposed Business Solution

Product class, type, category information normalized from PRODUCT TABLE

o Run inventory reports on different combination of products

o Each product has a unique identifier (SKU) to quickly find products

o Other fields such as name, type, class, category can be used to find the product

ORDER_ITEM TABLE tracks individual line item information normalized from the CUST_ORDER TABLE

o Allows aggregate line items to be associated with one order

CUST_ORDER TABLE is associated with the CUSTOMER TABLE

o Can be joined to track customer’s orders and total amount spent

o Can also be joined with ORDER_ITEM TABLE to track individual line item purchases

o Ability to determine PlayBall’s best customers

INVOICE TABLE tracks invoices from the CUST_ORDER TABLE associated with each employee in the EMPLOYEE TABLE

o Can be joined to obtain how much each employee sold, number of total invoices, and their commission amount.

o Ability to determine PlayBall’s best employees.

PRODUCT TABLE designed to keep track of inventory

o Keeps track of current quantity and reorder quantity amount if inventory is too low.

o Associated with ORDER_ITEM TABLE to determine the frequency of products purchased, order quantity, and backorder quantity.

o ORDER_ITEM TABLE will update the PRODUCT TABLE to reflect current inventory levels

VENDOR TABLE can be linked with PRODUCT and ORDER_ITEM TABLES to determine quality of vendors.

o ORDER_ITEM TABLE tracks product defects and return quantity.

o Can be joined with PRODUCT and VENDOR TABLES to determine Playball’s best vendors.

To Be Business Process Flow

Data Requirements & Data Definitions

Ability to find product information quickly through quick searches of product class, type, category, and specific product item.

Track employees’ associated orders to measure sales performance. Analyze and measure vendor quality by tracking backorder quantity and customer returns

resulting from defects. Assess customer loyalty by tracking the number of purchases and total costs spent by

each customer. Ability to generate inventory, sales, and commission reports. Quantity amounts for each

product type, class, and category, order item sales, total sale amount, and employee commission amounts are needed.
