CHAPTER 3
SYSTEMS DEVELOPMENT AND DOCUMENTATION TECHNIQUES
SUGGESTED ANSWERS TO DISCUSSION QUESTIONS
3.1

Identify the DFD elements in the following narrative: A customer purchases a few
items from a local grocery store. Jill, a salesclerk, enters the transaction in the cash
register and takes the customer’s money. At closing, Jill gives both the cash and the
register tape to her manager.
Data Flows: merchandise, payment, cash and register tape
Data Source: customer
Processes: capture sales and payment data and collect payment, give cash and register tape to
manager
Storage: sales file (register tape), cash register

3.2

Do you agree with the following statement: “Any one of the systems documentation
procedures can be used to adequately document a given system”? Explain.

It is usually not sufficient to use just one documentation tool. Every tool documents a uniquely
important aspect of a given information system. For example, system flowcharts are employed to
understand physical system activities including inputs, outputs, and processing. In contrast, data
flow diagrams provide a graphic picture of the logical flow of data within an organization.
Each alternative is appropriate for a given aspect of the system. As a result, they work together to
fully document the nature and function of the information system.

3.3

Compare the guidelines for preparing flowcharts and DFDs. What general design
principles and limitations are common to both documentation techniques?
Similar design concepts include the following:


Both methods require an initial understanding of the system before actual documentation
begins. This insures that the system is properly represented by the diagram.



Both measures require the designer to identify the elements of the system and to identify the
names and relations associated with the elements.



Both methods encourage the designer to show only the regular flows of information and not
to be concerned with unique situations.



Both approaches require more than one “pass” through the diagramming or flowcharting
process to accurately capture the essence of the system.

The product of both methods is a model documenting the flow of information and/or documents


in an information system. Both documentation methods are limited by the nature of the models
they employ, as well as by the talents and abilities of the designer to represent reality.

Your classmate asks you to explain flowcharting conventions using real-world examples.
Draw each of the major flowchart symbols from memory, placing them into one of four
categories: input/output, processing, storage, and flow and miscellaneous. For each symbol,
suggest several uses.
The major flowcharting symbols and their respective categories are shown in Fig. 3.8 in the text.
With respect to how the symbols are used, student answers will vary. Possible examples include
the following:
Input/Output Symbols
 Document: an employee time card, a telephone bill, a budget report, a parking ticket, a
contract
 Display: student information monitors, ATM monitors, the monitor on your microcomputer.
 Manual input: cash registers, ATM machines
Processing Symbols
 Processing: processing a student payroll program, assessing late fees
 Manual operation: writing a parking ticket, preparing a paper report, collecting and entering
student payments
Storage Symbols
 Magnetic disk: alumni information data base, a report stored on your PC hard disk
 Magnetic tape: archival student information
 On-line storage: a student information data base or an airline reservation data base stored
on-line.
 File: purchase order file for a department, a student housing contract file
Flow (Miscellaneous)
 Communication link: a telephone linkage that connects you to an on-line data base.

a. Prepare a document flowchart that indicates the interaction and use of these
documents among all departments at Beccan Company’s central facility. It should
provide adequate internal control over the receipt, issuance, replenishment, and
payment of tires and supplies. You may assume that there is a sufficient number of
document copies to ensure that the perpetual inventory system has the necessary
basic internal controls.
b. Using the flowcharting conventions discussed in Focus 3.2, critique the instructor
provided CMA solution. List all the ways the CMA solution violates those
flowcharting guidelines.
Adapted from the CMA Exam. Note: the CMA solution shown does not follow the flowcharting
conventions discussed in the chapter. When the authors use this problem they have the students critique
the CMA exam solution (assignment 3.5b), based upon the conventions discussed in Focus 3.2.
