The are steps involved in building and analyzing the model.
Typically
for a large and complex decision this is done in a workshop
setting
and the ChoiceResults Brainstorm whiteboard is used to
organize the
goal and criteria, rate the model and analyze the results.
Identify the goal
Brainstorm the criteria
Organize the criteria into like objectives
Identify the alternatives
Rate the criteria and alternatives
Analyze the results
1. Identify the Goal
The first step in building a model is to identify the
decision that is
being made such as "Select Information System", "Select
Data
Migration Vendor", etc. The goal is then added to the model
using
the brainstorm whiteboard.
2. Brainstorm the Criteria
Add the criteria that is used to affect the decision is
identified and
placed on the brainstorm whiteboard.
3. Organize the Criteria into Like Objectives
Organize the criteria into similar objectives by graphically
connecting
a criterion to a parent criteria (objective) or the goal. As
the
hierarchy is established by organizing the criteria the
hierarchy tab
view changes to reflect the relationships.
You can also establish the hierarchy or modify the hierarchy
using the
promote and demote buttons on the hierarchy tree view.
You can edit the existing objects, change their location,
size, collapse
branches for clarity and so forth. See Brainstorm for details
on how
to edit the hierarchy and whiteboard graphics.
4. Identify the Alternatives
Identify the different solutions or alternatives that are
being decided.
This can be done at anytime while you are building the
model.
You can mange the alternative (make them active or inactive)
by
right-clicking in the alternative list and displaying the
alternative
manager. Using the alternative manager alternatives can be
made
active in the decision or inactive (excluded from the
decision).
5. Rate the Criteria and Alternatives
The criteria and alternatives are rated. When all of the
ratings have
been completed the results are automatically calculated. See
Rate the
Criteria and Alternatives for details.
6. Analyze the Results
The results are calculated once all of the ratings have
been
completed. The results can be analyzed and the weights of
the
criteria can be changed in order to understand the sensitivity
of each
criterion to the results. See Analyze the Results for
details.
