ave been carried out correctly and that no faults have been introduced in the software by the changes, and (2) ensure that software is correctly returned to service. Field upgrade procedures should be described. Style means that the maintenance manual is understandable to the users. A precise definition of each technical term should exist, either in the maintenance manual or in a separate dictionary or glossary. The maintenance manual may be organized in the style of a reference manual, with the assumption that its users are well trained. Traceability means that a forward trace exists between the maintenance plan and the maintenance manual, which shows how each requirement is carried out by the maintenance organization. B.3.3.8.2 Review Guidance for SMMs Prior to the review of the maintenance manuals, the reviewer should determine if maintenance will be done by applicant/licensee or vendor personnel. In many instances, the applicant/licensee only performs maintenance to replace failed circuit boards, and the boards are then sent to the vendor for repair. In this instance, the maintenance manuals used by applicant/licensee personnel do not need to be as detailed as would be required if the applicant/licensee was doing board level repairs. The reviewer should use judgement to determine how adequate the level of detail is in each of the maintenance manuals. B.3.3.9 Installation Activities - Software Training Manuals (STMs) NUREG/CR-6101, Section 3.7.3 “Training Manuals,” contains relevant guidance. One or more STMs should be produced. They may be incorporated into a system training manual. Because training manuals do not impose requirements on the software itself, the functional characteristics described in other subsections of this BTP are not directly relevant. However, the software development process characteristics listed below should be exhibited by software training manuals. B.3.3.9.1 Process Characteristics of STMs The STMS should exhibit each of the
