Steps of the policy analysis process

Recently I have become quite fond of review articles, frameworks, procedures and so forth. Metascience and synthesis of information seem very relevant and important.

Today I came across this 8 step procedure for "Rational-style model-based policy analysis" by Walker (2002)*. Decided that it is worth sharing. Problem formulation, objectives and criteria, scenarios, models... This procedure got them all in nice order!

1. Formulating (and reformulating) the problem.
2.Specifying objectives and deciding upon criteria.
3.Identifying alternatives.
4.Designing scenarios to deal with uncertainty about the future.
5.Building models.
6.Collecting data.
7.Analyzing alternatives and drawing conclusions.
8.Documenting work and communicating results.

(The author notes that this process typically does not proceed in a linear fashion but a significant amount of iteration occurs between the steps.)
