With growth of the company the functional areas also started to expand and included such as: (1) procurement, (2) manufacturing, (3) ordering, (4) sales, (5) admin/accounting. The document flow was expanding сcorrespondingly, therefore, higher level of automation in the internal company’s system become a must. All the accounting and financial documentation were processed in three separate computer applications (order filling, invoicing and payroll). The next step in automation was to shift towards a database approach. Currently Wheels & Tyres Inc. has a company-wide database with which all the other applications are interacting. Overall economic growth in the country has led to increase in car purchases and consequently the demand for tyres was constantly increasing. When the new order for tyres is placed, the packaged tyres are delivered to the customer and invoice is issued. The existing applications cover order filling, invoicing, accounts receivable and payable, inventory control and payroll. The data in the system is organized around entities including customers, orders and invoices. The key challenge that Wheels & Tyers Inc. is facing right now is to develop the application that suits the full spectrum of company’s needs. Questions (Please do it sincerely) Prepare a context diagram for the new system.
