that process. A general description of the environment (such as temperature, humidity, vibration, and rack space) within which the computer system and software system is qualified to operate should be included in the plan. Organization requires a description of the software installation organization. The plan should describe the boundaries between the software installation organization and the broader safety system installation organization. Reporting channels should be described. It is acceptable for the installation to be performed by the development organization or by the customer. Responsibilities requires a definition of the responsibilities and authority of the software installation organization. If installation is performed by the customer, then the delineation of responsibility between the development organization and the customer should be defined in such a way that misunderstandings in communications between the two organizations are kept to a minimum. Implementation Characteristics The implementation characteristics that the software installation plan should exhibit include measurement and procedures. Measurement requires a set of indicators used to determine the success or failure of the installation effort. The plan should require that data associated with the installation be collected and analyzed. The error rate found during installation activities should be measured, recorded, analyzed and reported. Procedures requires a description of the installation strategy. The plan should describe procedures for software installation, and for combined hardware/software installation. The plan should describe the methods, procedures and controls used to ensure that the success or failure of the installation effort can be reliably determined. Checks should be required to ensure that the computer system is functional, that the sensors and actuators are functional, that all cards are present and installed in the correct slots, and that the communication system is
