Decision-making Model
One of Watertime’s objectives was to elaborate a decision-making model that would
enable a comparative evaluation of various options on a multi-criteria basis
have participation and flexibility at its core
The model uses
Multi Criteria Decision Analysis (MCDA) approach
Good Practice Recommendations and related
Discussion tools

MCDA
Specifying criteria
Specifying options
Evaluating options in terms of criteria
Weighting criteria
(a) Results (a score for each option) (b) Conclusions

4. Participation and MCDA

Participation and MCDA
The Watertime model aims to combine MCDA and participation in a novel way: participative MCDA, publically available online.
MCDA is usually
aimed at a single person making a decision
requires costly software
requires expert support
Online participation usually
is less focussed on the details of how a decision is to be reached
does not provide any kind of decision analysis tool

5. Robin de la Motte Watertime model and website 25 November 2005
The Watertime model aims to combine MCDA and participation, in a system publically available on the internet.
This involves
Structured analysis of decisions
Transparency on possible options, criteria for decision-making, etc
Public deliberation on relative importance of criteria, options excluded, risks overlooked, etc
And thereby
Clarifies the nature of decisions for decision-makers
Strengthens public sphere and transparency
Enables structured and problem-focussed stakeholder dialogue
Complements citizen juries and other public participation methods
