achievement of agility is to obtain the alignment
through the different layers and components of the
enterprise architecture. We have tried to define each
type of agility by report to the whole layer of the
enterprise architecture.
Strategic / Business Agility which encompasses:
business architecture as well as the process.
• The ability of an enterprise to develop and
exploit it’s inter and intra-organizational
capabilities.
Operational / IT Agility which includes:
functional architecture, and application technique.
Reconfiguring or replacing your information
technology systems when new marketplace realities
change the way you have to do business.
Agility is analysed in the perspective of structural
design within the enterprise architecture as a whole
and in the different layers of the enterprise
architecture.
3 STUDIES OF APPROACHES
In literature, several approaches are relevant to the
problem of the business IT alignment (Couto et al.,
2015; Engelsman et al., 2011; Doumi et al., 2013).
Without taking into account the business agility, other
researchers (Tallon and Pinsonneault, 2011;
Wirattanapornkul, 2012) have determined the
relationship between the agility and the alignment and
in concluding that the agility is perceived as a result
of the alignment. Others (Lemrabet, 2012) have
developed service-oriented approaches that focus on
business process management and service-orientation
with the strategic alignment, by making the business
agile.
This part is intended to define a multi-dimensional
grid, which encompasses all the approaches which
speak of the set of strategic alignment and agility
which are refined by the criteria of a general
definition "A company is called agile when its
operational components work together in synergy and
in addition: if one happens to have a system that
anticipates and detects the change in order to
allow the integration and reactivity". Anticipation,
detection of change, and the reactivity, have two sub-
levels: level of abstraction and the nature of the
reactivity to determine the impact of agility on the
strategic alignment.
3.1 Analytical Grid
According to the analytical grid, Tallon and Pinson-
neault (2011) have made a comprehensive study on
how strategic alignment would have a positive or
negative impact on agility, "Agility is perceived as a
result or benefit of alignment".
Oosterhout (2010) has designed a model that
anticipates what could happen and thus detect
changes internal or external that can disrupt the
system. Further, Oosterhout considers this
extensively as factor which will thus concern the
changes in the system.
Agility and strategic alignment can be measured
together to see whether their co-habitation is what it
is necessary for the architecture of the company or
not.
Detection of change should be considered
explicitly as well as its impact on all levels of the
model, and we consider several criteria for that. First
of all, information on changes is to be collected.
Secondly these changes are to be analysed in the
framework of the enterprise information system.
Thirdly, the agility under the influence of IT is to be
evaluated with respect to the strategy of the company.
Fourthly, the design changes are to be validated as it
concerns the changes collected.
4 DISCUSSION
It is assumed that a system is aligned when each level
of the architecture is in correspondence with the
various levels of abstraction. Agility can give us an
added value for this system and thus we can consider
agility to be a level of maturity for the alignment, a
model which will thus make the system aligned and
agile any by measuring the agility, we can establish
that.
What would be the impact of agility on an aligned
system? Perhaps an evolution? In this section we
quote essential points concerning the possibility of
transforming an agile business, knowing that its
system is still aligned and dynamic. The alignment is
the connection between the entities. When there is a
change it is the whole system that is affected. We
argue that change is rarely considered as a concept in
itself. It is therefore seldom represented.
In effect, it is difficult to reason on a concept if it is
not clearly formalized.
When there is a change environmental factors
which affect the aligned system, the first thing that
must be done to change it is the strategy of the
company which has its turn determine the key
objectives which must be consistent with the
objectives regarding the IT.
