Over the last 15 years,
structurational approaches have become an important theoretical
perspective within the IS research community (Jones, 1999; Poole and
Desanctis, 2000; de Vaujany, 2001), and exert an increasing influence
on management studies as a whole (Whittington, 1992; Rojot, 1998;
Giordano, 1998), whether in French or English-speaking literature.
What does this
theoretical perspective consists in and how can one account for its
breakthrough? As regards Information System research, it seems that
the structurational framework is particularly relevant to
understanding the potential “social innovation in use”
IT implementation can result in. Basically, structurationists
illuminate on a fundamental socio-technical dynamic. IT implementation
can be either neutral, regenerative, or disruptive for a given
organisation. This paper uses both a pure structurational perspective
(Giddens framework) as well as a rival model (the morphogenetic
approach), in order to deepen these basic states and to develop a
qualitative evaluation of IT use.
In the first
part of this article, structurational approaches along with three
“socio-technical archetypes” are introduced. They enable the reader to
capture the gist of structurational approaches. A dynamic way of
combining them is also proposed, by means of two appropriative
trajectories. Then, in a second part, the preceding reading grid is
illustrated and accommodated through four case studies.
1. Structurational approaches : an
overview.
1.1
The sources of structurational
approaches
The IS research
community, like many other communities in social sciences, can adopt
several theoretical stances to study its object of research. On the
whole, they vary in accordance with the importance they give to action
or structures, to human agents or the system they belong to, to
functionalism or emergentism (see table 1). Thus, from Archer’s (1982,
p 455) point of view, “successive developments have tilted either
towards structure or towards action, a slippage which has gathered in
momentum over time”. It is nonetheless very rare that social theory
really makes it possible to combine action and structure in a dynamic
way.
Taking this
starting point, structurational approaches, whether Giddens’
Structuration Theory (Giddens, 1979, 1984), Bhaskar’s TMSA
(Bhaskar, 1979), Archer’s morphogenetic approach (Archer, 1982, 1995)
or some institutionalists,
have tried to develop some kind of an integrative perspective.
Structurationists have worked out general frameworks aiming at
grasping the way people produce or reproduce social structures in
societies. The gist of the matter for them is thus to understand the
various conditions in which the role system a society is based on can
evolve, putting together action and structures. Up to a certain
extent, structurationists’ problematic is a very general question
regarding every social scientist.
In accordance
with Jones (1999) and de Vaujany (2001c), it is important to notice
that structurational approaches, in spite of being consistent, do not
form a homogeneous stream of research. Some researchers give a certain
exteriority to structures, a “causal efficacy”, in order to study the
interplay between action and structures. They adopt a very analytic
way of analysing IT use. Other researchers try to “conflate” action
and structures. Considering structures only as “mnesic traces” in the
mind of actors, they view their conditioning power as depending on
users’ willingness. The resulting theoretical framework then draws
on a psychosocial perspective. In a nutshell, these are the main
differences between the morphogenetic approach
(cf. Archer, 1995) and Structuration Theory (Giddens, 1979, 1984).
Archer puts forward two basic propositions that underlie her model :
(i)
“That structure necessarily
pre-dates the action(s) leading to its reproduction or transformation”
(ii)
“That structural elaboration
necessarily post-dates the action sequences which gave rise to it » (p
15)”
In line with
these propositions, Archer takes three social steps into account :
structural (or cultural) conditioning, social (or cultural)
interaction, structural or (cultural) elaboration. Past actions thus
have effects “in their own right” later on. They constrain and
facilitate actors' actions by means of a conditioning process, i.e.
they “simply set a price on acting against one’s self-declared
interest and a premium on following them (consequently detectable
regularities do not even approximate to constant conjunctures” (p 90).
This principle does not result in a new form of determinism. The
middle part of the morphogenetic/morphostatic cycle includes a
potential “promotive creativity”, innovative actions. Besides (and
this is a key difference), Archer’s model integrates various kinds of
actions, linked to two sorts of agents : “corporate” and “primary”
agents. The first category has a lot of resources, clear-cut projects,
and a strong group awareness. The second category has only marginal
resources at its disposal, no group consciousness and no projects
motivated by a common interest. The first group plays a much more
active role in structures evolution”.
But in both cases, the final form of the social system is not produced
by a specific groupal action. “Unexpected consequences”, emergent
properties define the final outcome. The latter can be described
through four “second order emergent properties” (Archer, 1995 ; p
218) : necessary compatibility or incompatibility ; contingent
compatibility or incompatibility. They each correspond to four
situational logics : protection, compromise, elimination, opportunism.
To conclude
this brief presentation of the Morphogenetic model, it is important to
stress an important point. Even specific, Archer’s model shares a
common matrix with Structuration Theory which makes it possible to
present it as a global stream of research. Starting with the same
project (recombining structures and action), they both agree on the
following propositions (Hodgson, 1999):
a)
Dependance of social structures upon individuals;
b)
Rejection of methodological
individualism
c)
Dependence of individuals upon
social structures
d)
Rejection of methodological
collectivism
Nevertheless,
structurational approaches are not a “ready to use” research
framework. Washam introduces Structuration Theory by speaking about a
“meta-theoretical” approach (Walsham and Han, 1991; Walsham, 1993)
which needs to be associated with intermediate theories, that is to
say a web of concepts more linkable to the study of a concrete
setting. Structurational approaches are then a sort of theoretical
galaxy which will “sensitise” the researcher to some important aspect
of the social phenomena under study, and which will help her/him to
give a minimal coherence and relevance to her/his construct.

1.2
Three socio-technical archetypes to
condense the structurational framework.
How can the
structurational approach be applied to the case of network technology
implementation ?
As suggested before, an intermediate theory is required. It is
proposed here to use an archetypal model consistent with a
structurational stance. This archetypal model consists of different
stylised elements (three socio-technical archetypes and two
appropriative trajectories) which will be helpful in shedding light on
socio-technical dynamics.
A
socio-technical archetype is a “structurational state, a long-lasting
socio-technical configuration described by means of structurationist
dimensions”. In other words, it is suggested that the social dynamic
linked to the use of IT can be described using three basic
ideal-types: Neutral (N), Disrupted (D) and Regenerated (R).
In the regenerated situation, the use of IT results in
new ways of interacting. New social structures are produced. Roles
within the organisation are redefined, which may also translate a
deeper change in organisational norms, interpretive schemes, or
facilities. Barley (1990) explains why the role system is studied to
examine the evolution of social structures: “If one conceives
structure as a global pattern that emerges from the relationships that
exist among all members of a collectivity, then it is possible to link
shifts in role relations directly and empirically to structural change
by examining properties of social networks” (p 69). Barley (1986 ; p
83) also suggests to find out organisational scripts, i.e. “Outlines
of recurrent patterns of interaction that define, in observable and
behavioural terms, the essence of actors' roles” (quoting Schanck and
Abelson, 1977). This is the precise technique implemented by Barley
(1986 ; 1990) to study the opportunity for structuring implied by the
use of scanners in hospitals and the changes in the
radiologist-technician interactional scripts.
In the neutral case, either the use
of IT dissolves into pre-existing social structures or it is not used
at all. The role system is kept and technology is implemented in a
routinely. Organisational scripts are not modified. The “government
co-ordination agency” case as presented by Walsham (1993; p X)
illustrates this situation. Studying one of the systems implemented,
Walsham explained that: “(…) the routinisation of the activities
outside the GCA was not disrupted by the Intis system; they carried on
largely as before with little change to their structure of
signification with respect to their role and work on development
activities, and the need to be coordinated between agencies”.
In the disrupted situation,
structures are destroyed by IT use or create tension with specific
social structures. This last configuration can thus can be an
archetype “per se”
or can be superimposed on the two preceding archetypes. For instance,
regenerated and neutral situations can coexist. Developing his case
study, Barley (1986) explained that : “As role reversals, clandestine
teaching, and incidents of blaming the technologist gradually defined
a new interaction order, the radiologists’ moral authority tarnished
and the technologists began to regard the inexperienced radiologists
with disdain (…) Unaccustomed to having their knowledge perceived as
inadequate, anxious that they might make a serious mistake and baffled
by the computer technology, they began to express hostility toward the
technologists.” (Barley, 1986 : pp. 93-94).
An interesting point can be raised
at this stage : these three socio-technical archetypes can be
interpreted either from Archer’s (1995) or from Giddens’ (1979, 1984)
perspective. On the one hand, from the latter, socio-technical
archetypes are specific psycho-sociological situations where
structural properties are instanciated in a particular way. Technology
does not exist away from its use and agents willingness is central in
every social move. Ontological security
is either maintained or broken by actors’ actions. On the other hand,
from the former’s perspective, socio-technical archetypes have a more
concrete and objective dimension. Socio-political struggles, material
conditions, agents’ various creative capacities weigh on the potential
evolution of the social system.
The chart on the newt page describes
the archetypes by means of Structuration Theory and the Morphogenetic
Approach :

|
There
is a transformation of social structures. Action is stronger
than structures, more powerful or innovative than some
conditioning element (S<A). In Archer’s perspective, this can
have a social cost for actors. |
Table 2: Structurational
sub-streams and their interpretation of each archetype.
1.3
Two general sequences of archetypes :
the balancing-point and the improvisational dynamics.
1.3.1.1
Using the three
socio-technical archetypes previously worked out, it is now possible
to describe some general trajectories linked to IT implementation. An
appropriative trajectory can be defined as “a general and regular
sequence of socio-technical archetypes, a structurational dynamic”.
From our point of view, the theoretical and empirical literature
suggests two trajectories : the balancing point dynamic and the
improvisational dynamic.
1.3.2
The balancing-point dynamic.
From this first
perspective, routine is the most common state of a social system. IT
uses can thus have two sub-trajectories, each leading to the same
final state. One the one hand, the new technology can first involve
analogical uses, then local or global disruptions concomitant with
local changes, before a global move to the regenerated socio-technical
archetype and later, to a new routine (sequence N-D-R-N. We go through
two symbolic gates: G1 (the move from routine to change) and G2 (the
move from disruption to a new social order). This first sequence
corresponds to the situation described by Barley (1986, 1990). The
general idea is summed up this way by the author : “(…) to occasion
the structuring of organizations, technologies first disturb or
confirm ingrained patterns of action to reformulate or ratify scripts,
which, in turn, delimit the organization’s institutional structure”
(Barley, 1986 : p 84). On the other hand, the new technology can also
directly induce a regeneration of the social system (sequence N-R-N).
The case study developed by Orlikowski (2000) epitomises this second
situation. A new software results in new social configurations,
without major tensions for the role system. Anyway, whatever
sub-trajectory is taken into account, the gist of the matter lies in
going through the first symbolic gate (G1), which embodies the move
from the neutral archetype to another different archetype. The cases
developed by Walsham (1993), Grote and Baitch or Muhlman (2001)
illuminate these two points : the existence of a (strong) gate G1, and
the inertia of socio-technical systems. Activities then always come
back to a routinised state (“With time, recurrent behaviour leads to
the formation of an interaction order and a set of shared
typifications that generally acquire the moral status of
taken-for-granted facts” Barley, 1990 ; p 67).
As in the case of archetypes
themselves, the balancing point dynamic can be understood from
Structuration Theory or the morphogenetic approach points of view. As
regards Giddens, the overall process is in the mind of actors. The
gate G1
is the point where the “ontological security” feeling is broken (for
the first sub-trajectory). Anxiety resurfaces. And all social
activities sooner or later become routine. That is why, if the dynamic
ends with the regenerated archetype, the system always comes back to a
long-lasting neutral archetype. How can one (a researcher, a project
manager, a user…) judge if the organization comes back to the neutral
archetype ? From Giddens perspective (rather interpretative) it
all depends on the actor's point of
view. When what was a” social innovation in use” becomes routine from
the agents’ point of view, the system is back to the neutral
archetype. From Archer’s point of view, things are more concrete. The
tension is in the “conditioning context”, through logical or practical
incompatibilities. Agents have various interests, capabilities and
comprehension of the social contexts. Structures have, up to a certain
extent, heterogeneous “causal efficacy”. And the regenerated, neutral
or disrupted nature of the social system can be determined
“objectively”.
1.3.3
The improvisational dynamic.
A second appropriative dynamic is
put forward more and more in the structurationnist literature. It is
what is called the improvisational dynamic. Orlikowski (2000) recently
promoted this idea, which had been already presented in a non-structurationnist
article (cf. Orlikowski and Hoffman, 1997). From this point of view,
structurational processes linked to IT use are much more ongoing and
intertwined than the work of Desanctis and Poole (1994) or even than a
part of Orlikowski and Robey’s (1992) work may suggest. Archetypes
arise continuously in organisations. For the same part of the social
system, uses can be at the same time regenerating, disrupting, and
neutral. Technology is constantly “re-enacted” globally (its general
sense) or locally (the sense of a given functionality). The
consistence and stability of the first dynamic is questioned. It is
also likely that the sensemaking process is a bit different from an
improvisational point of view, with more retrospective creation of
forms.
1.3.4
Comparison of the two trajectories
It is possible to sum up differences between the
balancing point dynamic and the improvisational trajectory by means of
the following table:

Table 3: Comparison between the
balancing-point and the improvisational dynamic.
Is balancing-point trajectory
totally inconsistent with the improvisational dynamic?
We do not agree on this point. Everything depends on the level of
observation, the time scope studied, and the conditioning power of the
socio-technical context. In practice, it is also clear that most
organisational members behave simultaneously in improvisational and
balancing terms. IT users are thus different from jazz musician
and from the forces of law and order…But the forthcoming case studies
will now be helpful in precising this interesting point.
2. Illustration and adaptations of the
structurational approach : four case-studies.
In this second part, the theoretical
framework previously developed will be applied to four case studies :
A, B, C and D. For each case, the “premodel” will enter into an
assimilation-accommodation process. On some occasions, the data
collected was able to be assimilated by the premodel. Other times, it
was not possible, and it was necessary to accommodate it. This is what
happened with the appropriative trajectories.
The methodology
followed conforms to the case study methodology as proposed by Yin
(1994). Semi-structured interviews
were carried out with end-users and IS managers met several times. A
questionnaire was submitted as regards to their instrumental uses of
the technology. We also did direct observations of steering committee
meetings and read various internal and external documents.
The tool under
study (Intranets) has been divided into three sub-technologies :
(1)
Electronic mail
(2)
Newsgroups
(3)
Data bases and tools in an HTML
format
The interview
structure scrupulously respected these categories, with a part for
each tool.

The four sites
were not studied in the same way. A and B were analysed
longitudinally, i.e. by means of repeated interviews, and continuous
observations (one and a half years for A, one year for B). C and D
have been studied transversally. People were asked to retrospectively
reconstitute their appropriative dynamic. A single set of interviews
was used. Besides, study of sites A and B was more global than C and
D. For A and B, we tried to study the appropriative dynamic from a
corporate point of view, taking into account the company as a whole
(B) or looking at some regional areas (A). As regards C and D, the
research has been focused on very local dynamics : the security
service of a big R&D centre for C and headquarters for D.
2.1 Case A
For the first
site, the socio-technical context was classic. A was a big company
with a divisional structure, partly state-owned, and had been engaged
in telecommunication activities for more than 50 years. The group
changed significantly during the study: (end of 98-beginning of
1999) : more decentralisation, redeployment of administrative agents,
new product orientation (towards new technologies)… The Intranet was
rather a meta-Intranet, i.e. a technical structure destined to support
functional, divisional, regional or operational web sites.
The socio-technical configuration
clearly corresponded to the neutral archetype and illustrated the
difficulties to go through gate 1.
The overall
Intranet (launched two years before our research) was studied, along
with a regional sub-Intranet put at the users’ disposal one week
before the first interview. At all levels, the technology was used in
a way that strongly reproduced (and reinforced) organisational
compartments and the role system. Users from a given branch only
visited the part of the network dedicated to them. Newsgroups were
used in a rather conservative manner, in spite of their openness. As
soon as some deviant behaviours arose (for instance, criticism of
management) auto-regulatory mechanisms emerged. Contrary to the goal
assigned by IS managers to technology, Intranet was not at all a way
to develop more transversality within the organisation. Moreover, the
various control systems deployed by IS managers in order to channel,
limit or facilitate the use of IT were also strongly reproductive of
pre-existing social structures. For the regional Intranet, IS managers
were all located in the headquarters’ office, and no real transversal
webs were set up. Nonetheless, for a small part of our sample,
technology supported a decompartmentalisation of the organisation
through a catalysis phenomenon,i.e., "the willing transformation, by
means of a factor, in the context of this transformation, the
catalyst" (Avenier, 1999). Technologies were used in order to develop
transversal communications and cooperation. Users got in touch with
new people through the mail directory or Intranet bases. New social
structures come into being through other media such as telephone or
direct meetings. Intranet had only had a leverage effect on this
phenomenon.
However, a very
interesting pattern was also noticed. It was specific to the mail
system, and to the people of our panel located within the regional
head office :
the active traceability pattern, and the passive traceability pattern.
The active
traceability pattern had the following characteristics : every time an
employee took an initiative, he informed his superior by means of a
direct mail or copies (cc :) sometimes coupled with acknowledgement of
reception. The mail was then stocked by the user. We actually met
someone who kept three copies of their mails : on the person's
hard-disk, on the mail server, and on printed paper ! This type of
appropriation was rather specific to the regional headquarters, where
the atmosphere at work was deteriorating during the period of the
research. The reason for this was that several people were redeployed
from administrative functions to operational units. Therefore, people
did not want to give reasons to their hierarchy to redeploy them. All
this resulted in “unexpected consequences”: a break in confidence, and
paradoxically, a worse social climate.
The
interactional script can be described in the following
manner:

C1: Correspondent 1
C2: Correspondent 2
Figure 1 : The active traceability pattern.
C1 represents a
correspondent looking for active traceability. He or she communicates
with another actor, C2, in a hierarchical position (T1), using the
mail as some kind of informational shield. The actor then loses a part
of his or her autonomy, and at the same time gains more “ontological
security”. In the case of a conflict, he or she can defend him or
herself (T2) by means of the stored mail.
  
Figure 2: The passive
traceability pattern
A user (C1), in a
hierarchical position, communicates with another agent (C2) using
technologies without memory (T1). The agent C2 then tries to initiate a
written communication by means of e-mails (T2), and to commit C1.
2.2
Case B
In this second case study, the global
conditioning context was very different from the previous one. B was
also a large company, but with a relatively new identity. This was a
form of a financial structure, whose corporate agents had decided three
years ago to give a more industrial objective. What was important was
the development of an integrated supply towards customers as regards to
the optimisation of industrial processes. The group thus consisted of
many more heterogeneous entities with different categories of corporate
agents, and big “necessary incompatibilities”. Contrary to A, no real
cultural structures existed. The Intranet structure was also specific.
It consisted mainly of different Intranets (subsidiaries technologies),
and federative projects launched by central corporate agents. From a
purely technical point of view, things were also very contrasted, as
some companies used Lotus Notes, others a classic Intranet (with
browser), and others simply an e-mail system. The research concentrated
on the federative project.
As in the case of A, IT implementation
conformed to the neutral archetypes or more rarely, to the disruptive
archetype. IT uses strongly reproduced organisational boundaries. The
central databases structure and content reproduced and reinforced social
structures, and more precisely, the role system. A few local
morphogeneses were all the same noticed. This was the case of the
“alternative users” category. The starting point is the following : a
user who is both in administrative functions and an intense e-mail user,
suffers from the disruptive nature of his e-mail system : “The mail’s
problem is the interruption it can entail in work. Every time one
receives a message… between the phone and the average 30 e-mails
received in a 10 hours’ working day, it makes 2-4 mails an hour, and I
am interrupted every 20 minutes at least !”. This situation is
illustrated by the example of an auditor communicating with a set of
correspondents (C1),
themselves corresponding with another set of correspondents. In view of
the disruptions resulting from its reporting activities, the auditor
decided to develop a new appropriation pattern : “Every morning, I
switch on the mail system, and then switch it off until 2 pm, time at
which I consult it again. I also read my mails for the third time just
before going home. I realise that by opening the mail system every
morning, I could be kept abreast of an emergency, and could treat it
more effectively than if I left my mail switched on all day long with
new messages coming every five minutes.” But this new appropriative
pattern was not always accepted by the communication network. People
from the first circle of correspondents (C1)
gave phone calls, asking why the no one had answered the mail sent 20
minutes before. This could then lead to two kinds of “structural
elaboration”: morphostasy or morphogenesis. In the first situation, the
socio-technical system comes back to the original state. In the second
situation, a new local structure emerged, more alternative than
reactive.
Finally, it was also surprising to
notice a progressive local morphogenesis linked to the central IS
service. At the beginning of the Intranet project, IS subsidiaries were
rather reluctant to cooperate with central managers. But the group
developed a new tool : “Teamrooms”. This was a sort of private news
group targeting very specific communities, with discretionary access,
and a documentary database. The success of this technology was much more
important than the one of classic newsgroups. Many IS agents in
subsidiaries decided to ask central agents for the "model" in order to
develop their own "teamrooms". The competence of IS headquarters was
thus more recognised, along with its legitimacy.
2.3
Case C
This third
organisation was in the chemical industry. It was on the verge of a huge
merger with a former competitor, which raised a lot of fears about the
future. The study focused on the security department of a European
Research Centre of the company. Some members were rather reluctant to
actual or potential effects of Intranets. More precisely, with the
implementation of a security newsgroup, experts dreaded the emergence of
a disrupted situation, an endangered “cohesion of the service”.
Normally, engineers had a very informal way of counselling technicians
and researchers by walking around on the site or exchanging ideas on the
phone. Researchers used to ask the same question to the different
engineers.
They then chose the less constraining answer which was often formalised
by an e-mail (cf. figure on next page).
