AP2633: No enough to solve a collaborative problem

3. LITERATURE REVIEW
Ways to solve the Problem
Industrial Practice Problem
The Organisation evolves faster
than the standards. [3]
2. Not enough monitoring
and control are
considered as a major
cause of failure in
project management. [5]
4. Negotiation process is
considered as an iterative
process in complex
system design. [6]
5. AP2633 use task
precedence models
Monitoring and control of the
process are difficult
NPD process are difficult to model
compared to others as a
manufacturing [6]
Process we are interested on:
Collaborative process >>
negotiation process
1. Monitoring and
use of REX
3. A right process
implementation is
considered as a feature
for a successful project.
[4]
Literature suggests[8] :
Task dependency models
Actor based model

3. Towards the Actor Based Design
Task dependency models



Such as IDEF0
Iteration problem
Use iteration to resolve
information
interdependencies
between tasks.
Actor Based model



Process of social coordination
Actors negotiate tradeoffs
Conflicting perspectives
and goals.

4. Towards the Actor Based Design

We started by using a task dependency modelling
approach (IDEF0). : resolve information interdependencies
between tasks.

IDEF0 model was defined taking into account:
Stages proposed on AP2633 process
Internal interview at Airbus Group Innovations

We will pass to a multi-agent modelling:

Regarding AP2633
Clues to explore
•
Process is not monitored
•
The adherence to the process is
not measured
•
The organization evolves faster
than the standards
How to create a dynamic process?
(A process that can tolerate the
organizational change)
•
Global and local constraints are
not the same
How to take into account the global
(architect level) and the local constraints
(expert level)?
How to think the monitoring and
the REX for a collaborative
system?

6. CONCLUSIONS
1.
2.
3.
4.
The work done gave us some clues for the
collaborative design process.
Identification of the three main phases of
collaboration process and we compared to AP2633:
There is no monitoring or REX process
Dependency model help us to identify negotiation
points. (tasks, information flow and actors)
Dependency model allows us to define more activities
because of the flow controls and two related
scenarios. (Models research and capitalization).

7. Future work

More interviews: more focus on process of social coordination and on actors negotiation.

Model the iteration and the relationships between the
actors and their trade-off.

Use Cases: AP2633, dependency model, Actor based
model.
