Introduction

Part 3, Section 12 of this document provides information and technical guidance on Operations, Maintenance and Support and focuses on designing for maintainability within an operational context.

Hence, Section 12 of this document covers the following topics:

a) Operational Context.

b) Maintainability.

c) Designing for Maintainability, including safety, environment, layout and access considerations.

d) Checklist of Maintenance Design Factors.

Section 12 is concerned with providing data and guidance to optimise maintenance tasks and equipment. As the maintainer is also a user of the system, many of the design considerations covered in the other parts of this document are equally applicable to the maintainer. Section 12 covers some of the specific considerations that relate to maintenance and support that are not covered elsewhere, in order to increase awareness of the contribution Human Factors can make in the maintenance concept within the design requirements of a project.

Within a project, maintenance and support is managed through an Integrated Logistics Support Plan (ILSP) that includes a maintenance policy detailing maintenance requirements, including a specification to achieve mission objectives. The policy should also emphasise, for example, the importance of having a maintenance history log to ensure traceability, and to allocate responsibility for maintenance tasks to be performed in different types of locations. In addition, issues that affect the maintainer as a user are described in the context of their consideration during the design stage.
