Supportability Engineering Handbook: Implementation, Measurement, and Management

Appendix A: System Requirements Study (Typical Outline)

1 GENERAL

This is a stand-alone document that is initiated in windows D1 or O1 of a program. It is distributed to every individual involved with the program, so this section normally provides a description of the program and the basis for consistent understanding of program direction.

1.1 Scope and Purpose

An overall description of the program and organizational strategies

1.2 System Description

Functional or physical depending on program status

Brief but specific

For orientation

1.3 System Mission Profile

Statement of the need

Strategic use

Based on operational requirements

2 QUANTITATIVE SUPPORTABILITY FACTORS

This section should provide focus on the specific areas that are of concern for supportability and set the foundation for all future supportability engineering activities.

2.1 Operating Requirements

Detailed mission/use scenario

Measurement base

Frequency of use

Systems required

2.2 Number of Systems Supported/Fielding Plan

When and where systems will be placed into service

Duration of installation

Setup of support locations

Maintenance

Supply

Training

2.3 Transportation Factors

Deployability/mobility issues

2.4 Maintenance Factors

Significant issues/concerns for providing support

2.5 Environmental Factors

Geographic/climatic issues

"Green" issues (hazardous/toxic)

3 SUMMARY OF SYSTEM BEING REPLACED

This section should contain a detailed description of the system being replaced. The information contained in this section will be the basis for many supportability analyses conducted during acquisition of the new system.

3.1 Operating Requirements

Detailed mission/use scenario

Measurement base

Frequency of use

Systems required

3.2 Number of Systems Supported/Locations

When/where systems operated and were supported

3.3 Transportation Factors

Deployability/mobility problems/solutions

3.4 Maintenance Factors

Significant problems/solutions...
