Obtain an FRS from a local government operation to use as an illustration for this unit. Unfortunately, there are no readily available references to support this unit.

UNIT 61 - FUNCTIONAL REQUIREMENTS STUDY

A. INTRODUCTION

B. DEVELOPING AN FRS

1. Identify decisions

2. Determine information products needed

5. Determine GIS operations required

Scope of the FRS within the organization

C. METHODS FOR CONDUCTING AN FRS

1. Fully internalized

2. Focus group

3. Interviews

4. Questionnaire

D. COMPONENTS OF THE COMPLETED FRS

1. Definitions of information products

2. List of input data sets

3. List of GIS functions required

E. WEAKNESSES OF THE FRS PROCESS

Invalid assumptions

Awareness of GIS

Funding uncertainty

Changing needs

Value of GIS

F. IMPORTANCE OF THE FRS

EXAM AND DISCUSSION QUESTIONS

1. Discuss the methods you would adopt to carry out functional requirements studies for:

a) a National Forest with a staff of 200 and responsibilities ranging from timber sales to management of historical heritage

b) a small consulting firm with a staff of 5 specializing in site selection studies for retailers

c) a One-Call operation answering 200 telephone queries per day about the locations of underground utility facilities likely to interfere with construction projects

2. List and review the assumptions made by the FRS process discussed in this unit

3. In what ways is the GIS FRS process different from any other FRS process in information processing? Do the differences justify a separate approach?

4. Define the input data, products and processing needed for your campus student records system.

5. RFPs and functional requirements studies are often public documents, especially when public agencies are involved. Obtain one from an agency in your area, and discuss its contents using the framework described in this unit.
