Introduction

The objectives of this assignment are to assess your knowledge in (1) systems documentation; (2) analysis of internal controls; and (3) business process re-design.

To complete this assignment, you should form groups of five to six (5‒6) students. We will not adjust the assignment marks according to the size of the group. Technically speaking, a large group can “gain” an advantage. (We do have a policy to penalise non-participative group members. Please refer to the section Grading on page 3 in this document.) We do not allow students to form groups of seven. If you have a group of seven, we recommend you to split it into two groups. We strongly disagree that students try to complete this assignment individually.

Assignment Requirements

In this assignment, you are given a business case (see pages 6‒7 for the narration). The business case describes an inefficient revenue process at Excellent Cycle Company.

Task 1. Systems Documentation (8 marks)

Your first task is to document this process with data flow diagrams (DFDs). Lectures 3‒5 describe three kinds of DFDs: context diagrams, physical DFDs, and logical DFDs. In this assignment, you are asked to develop (i) a structured narration, i.e., a table of entities and activities, (ii) a context diagram, (iii) a physical DFD, and (iv) a level-0 logical DFD with more than three (> 3) bubbles, for the given process. In other words, you are not required to develop level-1 logical DFDs.

The lecturer suggests students use the following table structure to develop a structured narration. It is optional for students to include the columns, INPUT and OUTPUT, in this table.
