====== Foundational Concepts ======
At the most basic level, the IT4IT Standard defines the “Digital Management” of “Digital Products” in
order to create an efficient value delivery.
{{:0:img1514.jpg?400|}}

====== Top-Down Decomposition of the IT4IT Architecture ======
The IT4IT Standard is about defining the value stream, the associated functions, and the data objects
needed to control the planning, development, delivery, and run management of Digital Products. This
can be seen as a factory for digital.

====== The IT4IT Functionality Groups ======
Functionality groups provide an abstraction of what is needed to manage the new digital reality in a
way that helps to simplify conversations between interested stakeholders. In the IT4IT Standard, we
use it to describe a collection of functionality and data that is responsible for a well-defined part of the
overall value creation. We describe the groups at a high level, and we decompose one level to have
well-defined categories for defining the Supporting Functionality.

====== The Digital Value Network ======
A traditional model for defining factories is Porter’s Value Chain concept [Porter]. This revision of the
IT4IT Standard breaks with the Value Chain model and moves to the more recent concept of the Value
Network. This reflects that value creation is a complex interaction within many systems and
organizations.

====== The Seven IT4IT Value Streams ======
For the second decomposition, a split is made with the Digital Product as an abstract entity in a set of
data objects that form the essence of the Digital Product Backbone. This is complemented with seven
new value streams that, together, explain how to define and manage the delivery of digital value.

A value stream is a representation of an end-to-end collection of value-adding activities that create an
overall result for a customer, stakeholder, or end user. For more detailed treatment of the definition of
value streams; see the TOGAF Series Guide: Value Streams [G178].

===== Evaluate =====
The Evaluate value stream is about the continuous assessment and evaluation of the entire Digital
Product Portfolio to optimize the alignment of the Product Portfolio with the business strategy,
including the identification of new Digital Product opportunities that support business and technology
objectives.

===== Explore =====
The Explore value stream continuously explores new features and/or future directions of a Digital
Product aligned with strategic direction and business needs. It ensures the Product Design evolves to
facilitate innovation and optimize business outcomes.

===== Integrate =====
The Integrate value stream continuously designs and builds new Product Releases and makes them
ready for deployment to the market or the business. The Product Release is not limited to software
development; this value stream is also applicable for the development of infrastructure building blocks
and workplace services. The Product Release may be as large as an entire new product or as small as a
hotfix or a patch.

===== Deploy =====
The Deploy value stream deploys a Product Release into a production/operating environment (creating
a new instance or updating/removing an existing instance). The scope of this value stream includes
many different strategies for deploying Product Releases.

===== Release =====
The Release value stream provides consumers with digital Service Offers that represent a new instance
of a Digital Product or a change (including decommissioning) to an existing instance. A Service Offer
defines how to subscribe to a Digital Product and all other lifecycle interactions the instance will have
with its consumers, stakeholders, and support. The Service Offer can be made available for
consumption through a self-service portal or through Application Program Interfaces (APIs).

===== Consume =====
The Consume value stream is triggered when an entitled human or system actor accepts a Service
Offer related to a Digital Product. The value stream should support customer self-service and is not
limited to a single engagement channel. It orchestrates the actions required to fulfill consumption of
the offered service to ensure that the desired Digital Product is delivered within the agreed terms.

===== Operate =====
The Operate value stream manages the continuous operations of a deployed instance of a Digital
Product in a continuous manner. It is responsible for maintaining availability and performance within
the boundaries of agreed Service Contracts. The scope of this value stream includes managing any
compliance and security aspects of running Digital Product Instances and underlying systems.

====== The Seven IT4IT Value Streams ======
The seven IT4IT Value Streams are defined in Chapter 5. Each IT4IT Value Stream depends upon an
end-to-end flow of work – via data objects – through multiple functional components to deliver the
expected result for the customer, stakeholder, or end user.
The IT4IT Standard defines functional components as the application building blocks for managing
Digital Products. Related functional components are associated together into four functional groups. A
further decomposition is made from the four high-level functional groups into eight (sub-functional
groups that must be established in order to manage Digital Products: Strategy, Portfolio, Develop, Test,
Consume, Fulfill, Support, and Assure.

Each functional group manages one or more data objects which are controlled by applications. The
integrated data objects comprise the Digital Product Backbone and Service Offer Backbone which
ensure traceability through the Digital Product Management lifecycle.

====== Concepts Recap ======
The IT4IT Standard defines seven value streams that manage the Digital Products. Information on the
Digital Products is tracked through a set of interconnected data objects managed by functional
components.
