Þ

1.3 Scope

Describe the scope of the software application to be produced.

Þ

1.4 User Characteristics

Identify each type of user of the software by function, location, and type of device. Specify the number of users in each group and the nature of their use of the software.

Þ

Section 2. Assumptions, Dependencies, Constraints

2.1 Assumptions

Describe the assumptions that can affect the requirements specified in this SRS.

Þ

2.2 Dependencies

Describe the dependencies that can affect the requirements specified in this SRS.

Þ

2.3 Constraints

Describe the constraints that can affect the requirements specified in this SRS.

Þ

Section 3. User Requirements

List the user requirements from a users perspective..

Þ

Section 4. System Architecture

4.1 Proposed System Architecture

Should include appropriate drawings and descriptions to clearly articulate the proposed system architecture..

Þ

Section 5. System Requirements

5.1 Business Requirements

Describe all business requirements for the software.

Þ

5.2 Functional Requirements

Customize this subfunction to contain the subfunctions necessary to comprehensively define the fundamental actions that must take place within the software to accept and process the inputs and to process and generate the outputs.

Subfunction templates for each of the means of specifying functional requirements are provided below.

5.2.xf Function X

When functional decomposition is used as the means of specifying the functional requirements provide a 3.2.xf subfunction for each function. Each 3.2.xf subfunction should be labeled and titled appropriately for a specific function, where xf is the appropriate sequential subfunction number and X is the name of the specific function.

5.2.xf.1 Function X Purpose

Describe the intent of the function.

Þ

5.2.xf.2 Function X Inputs

Describe the inputs to the function.

Þ

5.2.xf.3 Function X Operations

Describe the operations to be performed within the function.

Þ

5.2.xf.4 Function X Outputs

Describe the outputs from the function.

Þ

5.2.xu Use Case Y

When use cases are used as the means of specifying the functional requirements, provide a 3.2.xu subfunction for each use case. Each 3.2.xu subfunction should be labeled and titled appropriately for a specific use case, where xu is the appropriate sequential subfunction number and Y is the name of the specific use case.

Within each use case subfunction, specify the use case information, including the actor, pre-conditions, post-conditions, scenarios, and alternate scenarios.

Þ

5.3 Logical Data Requirements
