of an enterprise. The foundation for execution
depends on the proper alignment between the
business objectives and the IT systems using a
direct logic.
First the administration defines an strategic
direction; then, the IT unit, ideally in conjunc-
tion with the business administration, designs a
set of solutions provided by the IT for sustaining
the initiative; and, finally, the IT unit offers the
applications, data and the technological infra-
structure to implement the solutions. This process
re-starts always when the administration defines
other strategic initiative.
In reality the researchers realized that the
traditional approach for IT development inside
the enterprises was related to what they called the
establishment of a set of silos , a set of applications
inside the enterprise. Individually those applica-
tions worked well. Together they impeded the
enterprise efforts to coordinating the processes to
customers, input suppliers and workers; in other
words, they did not constitute a foundation for
execution .
To overcome this silos stage, and to build an
efficient foundation for execution , Ross, Weil e
Robertson (2008) proposed three key-disciplines:
1. Operational Model : it is the form to integrate
the information assets and to establish patterns of
the business process to offer goods and services
to customers; 2. Enterprise Architecture : it is the
organizational logic of the business processes and
the IT infrastructure, reflecting the requirements of
integration and patterns of the operational model
of the enterprise; and, 3. Model of involvement of
the IT : it is the governance mechanism systems
that assures that the business projects and the IT
reach their enterprise objectives either local or
in general.
The Enterprise Architecture and the Model of
Involvement of IT inside the enterprises are con-
stituted in the evolution of Maturity Stages of the
Enterprise Architecture . According to Ross, Weil

the Architecture-governance-
enterprise growth Analysis

The IT management methodology inside the IN-
MATE tool is based on three approaches: a) the
Enterprise Architecture as an Strategy approach,
which was first developed by the Massachusetts
Institute of Technology (MIT) Sloan Center for
Information Systems Research (US) and the IMD
(Global Business School/Switzerland); the Enter-
prise Governance approach, based on the modern
industrial (and services) organization theory;
and, c) Enterprise Growth approach, based upon
the economic theory of the contemporary firm.
The three approaches can be briefly described
as follows.
Amongst the approaches investigated by this
paper in respect to enterprise architecture, one
can be distinguished: that one from the MIT
Sloan Center for Information Systems Research-
CISR/MIT (Ross, Weil, e Robertson, 2008). After
the development of a research of ten years about
the IT impact on the performance of circa of
500 companies, researchers from the CISR/MIT
arrived at some conclusions of enormous signifi-
cance for the understanding of the role of IT on
the enterprise performance.
According to the MIT´s researchers the reason
why some enterprises - and not others- reach
a superior degree of execution and manage to
explore what they do better to obtain agility and
profitability, is because they have a better execution
foundation . This foundation for execution consists
of the IT infrastructure and of the digitalized busi-
ness processes that automate central capacities
