(1) A process is a defined activity, related to planning and/or implementation, carried out to achieve the objectives of the program. A process commonly encompasses multiple procedures that are linked or coordinated to accomplish the process objectives (see procedure). See "Processes". (2) Functions decompose into sub-functions, and then into processes, which are low-level activities that have a definable beginning, end, and output. Processes may be grouped together to form sub-functions, which in turn may be linked and form a function (see "Function")
