Group-Based Teaching Method

Demonstrate ability to critically plan, analyze, and design information systems.

Overview:

A2Z is a company specialized in producing and selling furniture products. It does not only sell products it produces but also products it imports from other vendors. As a step to improve its operations, A2Z wants you as a systems analyst to plan, analyze, and design an information system for its ordering operations.

The new ordering system should integrate with and accept requests from the production system. The production system will send requests of items needed for producing furniture to the ordering system where each request includes a list of products to be ordered. Each product in the list is specified by a product code, description, current level in inventory and the minimum level of this product to be held in inventory.

When a request is received, the ordering system will prepare list of vendors which includes vendors' codes, names, contacts, phone numbers, cities and whether if A2Z had ordered from this vendor before. Then, the ordering system will send each vendor in the list an order corresponding to the products offered by that vendor. The order includes the products' codes, descriptions, and required quantity.

When a vendor processes the order, he will send back to A2Z ordering system an invoice including products' codes, descriptions, prices, and discount. Every time the ordering system receives an invoice, it will send a payment and forward to the production system the updated list of inventory including products' codes, descriptions,and the total quantities of products available in inventory.
