Content:
related to a specific life cycle topic. Design output - Documents such as drawings and specifications, which define technical requirements of structures, systems, and components. For software, design outputs include the products of the development process that describe the end product that will be installed in the plant. The design outputs of a software development process include software requirements specifications, software design specifications, hardware and software architecture designs, code listings, system build documents, installation configuration tables, operations manuals, maintenance manuals, and training manuals. Deterministic timing - Timing is deterministic if the time delay between stimulus and response has a guaranteed maximum and minimum. Documentation - Information recorded about a specific life cycle activity. Documentation includes software life cycle design outputs and software life cycle process documentation. A BTP 7.14-5 Draft Revision 6 - August 2015 document may be in written or electronic format, and may contain text, illustrations, tables, computer files, program listings, binary images, and other forms of expression. Plan - The document describing a specific implementation of a process (i.e., an instance of a process) that will be implemented. Process - A series of actions, changes, or functions bringing about a result. A QA program is an example of a process definition. Requirements Traceability Matrix (RTM) - An RTM shows every requirement, broken down in to sub-requirements as necessary, and what portion of the software requirement, software design description, actual code, and test requirement addresses that system requirement. A.3.1 Definition of Software Planning Characteristics The following paragraphs define the software planning characteristics important to safety system software. The definitions given are specific to software. The planning characteristics can be divided into three sets: management, implementation, and
