ISO IEC TR 24774 pdf download Systems and software engineering — Life cycle management — Guidelines for process description
1 Scope
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.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
activity
set of cohesive tasks of a process
[ISO/IEC 15288:2008]
2.2
information item
separately identifiable body of information that is produced and stored for human use during a system or software life cycle
[ISO/IEC 15289:2006]
2.3
life cycle
evolution of a system, product, service, project or other human-made entity from conception through retirement
[ISO/IEC 15288:2008]
2.4
life cycle model
framework of processes and activities concerned with the life cycle that may be organized into stages, which also acts as a common reference for communication and understanding
[ISO/IEC 15288:2008]
2.5
process
set of interrelated or interacting activities which transforms inputs into outputs
[ISO 9000:2005]
2.6
process purpose
high level objective of performing the process and the likely outcomes of effective implementation of the process
NOTE The implementation of the process should provide tangible benefits to the stakeholders.
[ISO/IEC 12207:2008]
2.7
process outcome
observable result of the successful achievement of the process purpose
[ISO/IEC 12207:2008]
2.8
product
result of a process
[ISO 9000:2005]
2.9
system
combination of interacting elements organized to achieve one or more stated purposes
[ISO/IEC 15288:2008]
2.10
task
requirement, recommendation, or permissible action, intended to contribute to the achievement of one or more outcomes of a process
[ISO/IEC 15288:2008]
2.11
view
representation of a whole system from the perspective of a related set of concerns
[ISO/IEC 42010:2007, IEEE Std 1471-2000]
NOTE In standards being developed in ISO/IEC JTC 1/SC 7, the “system” (system of processes) referenced in the definition is the collection of system and software life cycle processes provided by ISO/IEC 15288 and ISO/IEC 12207.
2.12
viewpoint
specification of the conventions for constructing and using a view
[ISO/IEC 42010:2007, IEEE Std 1471-2000]
3 Characterizing the elements
3.1 Introduction
To enable uniform description additional characterization of the elements is helpful. The remainder of this Technical Report provides that characterization.
This Technical Report describes the following process elements:
⎯ The title is a descriptive heading for a process;
⎯ The purpose describes the goal of performing the process;
⎯ The outcomes express the observable results expected from the successful performance of the process;
⎯ The activities are a list of actions that may be used to achieve the outcomes. Each activity may be further elaborated as a grouping of related lower level actions;
