Techniques n° 40
At each phase of his work, the acoustical consultant has to
face these 3 variables.
The four phases of acoustical consulting work
The 4 phases of any acoustical consulting project are :
- Initial contact with the client, identifying the acoustic need
- Formulating an offer and contracting
- Real izing the work (measurements, simulations,
recommendations, solutions, follow-up and receipt of the
solutions, …)
- Conclusion and synthesis of the work
Phase 1 : Initial contact and entry, identifying the
acoustic need
In the beginning of the work, the human factor is the key factor
to focus on. First of all, the acoustical consultant has to identify
the actors and has to evaluate their position related to his
work. Sometimes the actor can be unique (but it is very rare),
sometimes many actors can influence his work. The consultant
has interest in making a list of all the actors and ranging them
in a two dimensional diagram (from [7]).
The synergy : the cooperation to promote his project.
The antagonism : the opposition against his project.
The position of the actors along these two axes help to identify :
The actors who have no special position related to the project :
they can be passive, hesitating (they are waiting for benefits
but they doubt) or “ecartelé” (favorable to the project but not
for the consultant for instance)
The adversaries : the irreducibles (revolutionary against the
project), opposants (against the project but ready to listen) or
unsatisfied (passive resistance)
The allies : the militants (favorable to your project) or critical
supports (positive but critical allies)
The sociodynamic advise to avoid the fight against the
adversaries and to invest in the “strategy of allies” that is
to adapt the project to transform the hesitating and neutral
actors into allies.
For each actor, the consultant has to identify their risks and
objectives and their resources (see [5] and [6]).
In each situation the behavior of an actor is strategic : he try
to solve the problem that he has himself in his own interest.
He try to maximize his advantages or profits and to minimize
his disadvantages or losses.
Each decision or situation is source of profit or loss for each
actor.
The actor uses his own resources increase them.
Each actor uses a coherent strategy in his own logic.
The knowledge of the different logics and strategies of
the actors helps the acoustical consultant in reducing
uncertainties in the human aspects of his work.
The personality of an actor can also influence his
behavior and strategy and the consultant has interest
in identifying the personality of each actor and take into
account it in his work. According to [2], we can classify
the actors as follows in their relations to other people.
The narcissic actor : all his behaviour is related to
himself. It is very difficult to influence him. The acoustical
consultant has interest in proposing him work that will improve
his image.
The possessive actor : his relations with others are oriented
to dominate the others. If you want to have him as ally, you
must accept to be dominated. They are very often oriented to
immediate results which will improve their power.
