Identification
This is the set of activities which identify the contents of the particular entity under consideration in terms of its boundaries and its relation to its internal and external environments.
Concept
The set of activities that are needed to develop the concepts of the underlying entity. These concepts include the definition of the entity's mission, vision, values, strategies, objectives, operational concepts, policies, business plans and so forth.
Requirement
The activities needed to develop descriptions of operational requirements of the enterprise entity, its relevant processes and the collection of all their functional, behavioural, informational and capability needs. This description includes both service and manufacturing requirements and management and control requirements of the entity — no matter whether these will be satisfied by humans (individuals or organisational entities), or machinery (including manufacturing-, information-, control-, communication-, or any other technology).
Design
The activities which support the specification of the entity with all of its components that satisfy the entity requirements. The scope of design activities includes the design of all human tasks (tasks of individuals and of organisational entities), and all machine tasks concerned with the entity's customer services and products and the related management and control functions. The design of the operational processes includes the identification of the necessary information and resources (including manufacturing-, information-, communication-, control- or any other technology).
Preliminary Design
Detailed design
Implementation
The activities which define all those tasks which must be carried out to build or re-build (i.e. manifest) the entity. This comprises implementation in the broadest sense, covering:
a) commissioning, purchasing, (re)configuring or developing all service, manufacturing and control software as well as hardware resources;
b) hiring and training personnel, and developing or changing the human organisation;
c) component testing and validation, system integration, validation and testing, and releasing into operation.
Operation
The activities of the entity which are needed during its operation for producing the customers product or service which is its special mission along with all those tasks needed for monitoring, controlling, and evaluating the operation. Thus the resources of the entity are managed and controlled so as to carry out the processes necessary for the entity to fulfil its mission.
