This Technical Report provides guidelines for the description of processes by identifying descriptive elements and rules for their formulation. It characterizes the following elements of process description: - Title; - Purpose; - Outcomes; - Activities; - Tasks; - Information items. In addition process views are described. It does not describe how processes are composed or otherwise aggregated into larger frameworks or architectures. ISO/IEC standards generally do not include a statement of purpose. This guide will not have a purpose statement. New IEEE Standard - Superseded. ISO/IEC TR 24774:2010 is adopted by this standard. An increasing number of international, national and industry standards describe process models. These models are developed for a range of purposes including process implementation and assessment. The terms and descriptions used in such models vary in format, content and level of prescription. ISO/IEC TR 24774:2010 presents guidelines for the elements used most frequently in describing a process: the title, purpose, outcomes, activities, task and information item. Whilst the primary purpose of ISO/IEC TR 24774:2010 is to encourage consistency in standard process reference models, the guidelines it provides can be applied to any process model developed for any purpose.
