| Objective /modeling focus |
To provide a neutral conceptual framework for
discussion and a platform for consensus |
Interactive construction of models to understand
the system dynamics, with the goal of obtaining a model derived
from consensus among participants |
Participatory generation of qualitative ecosystem
models to discuss ecosystem management, based on a postnormal-constructivist
approach in which consensus is not required

| Total
number of participants |
40
people (average workshop size) |
Small
(5–12) or big (50–100) groups |
12–15
people/modeling session, 1 session/group |
| Composition
of the modeling team |
One
facilitator, one modeler, three process coaches/recorders, one
gatekeeper |
One
mediated modeler |
One
brainstorming coordinator, two or three facilitators to guide
the modeling session
|
| Modeling
tools |
Qualitative
causal diagrams and quantitative dynamic models

STELLA-based

STELLA-based

| Session’s
design |
Large
group meetings and small group modeling meetings; the modeling
team develops the technical work before the sessions
|
It
is based on three sessions: qualitative model building, quantitative
model building, and simulations. |
One
session divided into two steps: brainstorming and qualitative
model building |
| Session
duration |
Seven
sessions with a total of nearly 50 h |
At
least 3 days |
3–4
h with a 30-min break between steps

| Advantages |
Large
number of participants; generation of a consensus model |
Large
number of participants: generation of a consensus model |
Generation
of conceptual models in one session per group; consensus not
required
|
| Disadvantages |
Workshop
duration; consensus is required |
The
overwhelming role of the mediated modeler; consensus is required
|
The
low number of participants in each session |
| Evaluation/validation |

interviews before and after the workshop |
