Case Study: Introduction to Systems Analysis

Question 1: The main business processes for the Cohen’s news agency booking system

The first main business process is Cohen’s news agency is to stock various newspapers. This is purposely to ensure that all the customers get the copy of the newspaper that the require. The papers arrive at the premise at 5:30 AM. Mrs. Cohen unpacks the load, separates the stacks into stacks of “Ages”, “Australians”, “Herald Suns” and “Clarions” and then inserts the special magazines and advertising material into the papers which carry them. The second process is the client to visit the organization at Chadford to open an account with them. Mrs. Cohen, who runs the business takes a blank card and the fills the essential details concerning the client. In essence, the details taken include the client name, address, the name of the newspaper required, the start date, amount owing, end date, and the status. The third business process that is conducted by Mrs. Cohen is to take one of the schedules of the delivery and change it. The schedule used for delivery entails the street name, house number, and the newspaper required (Aksyonov, Spitsina, & Smoliy, 2009).

The fourth business process takes place at 6 am when the boys arrives. They separate the papers based on the region to be delivered order. The papers are piled into four stacks and each stack entails four piles meant to be delivered in specific region to avoid mix up. Delivery schedule sheets are then used by the boys on their delivery routes. The fifth business process occurs at 6:45 AM when the tricycles are loaded and the boys set off to deliver the newspapers. The sixth business process occurs when the client wishes to change the type of newspaper to be supplied. The client visits the store or calls Mrs. Cohen to clarify this change. The seventh business process is for Mrs. Cohen to effect the change on the delivery card and adjust the delivery schedule.

The eighth process occurs when a client wants to cancel delivery for a known period. Mrs. Cohen alters the status from ‘on’ to ‘off’ and changes the start date. The ninth process occurs when a client wants to cancel delivery for unknown period. Then, Mrs. Cohen changes the status from ‘on’ to ‘off’ but does not adjust the start date. The tenth process occurs at the end of the day when Mrs. Cohen changes the distribution schedule for the following day. The eleventh process occurs at the end of the month when Mrs. Cohen prepares the invoices and posts them to the customers. The final business process in the premise occurs when the payments are received. Mrs. Cohen modifies the amount owing manually (Aksyonov, Spitsina, & Smoliy, 2009).
