The other prime considerations in communications in support of reform are transparency (the messages and measures must be clearly related to the purpose of the reform) and consistency (the messages and measures must be seen to be complementary and mutually supportive). During the implementation phase, adequate ex post analysis will only be possible if the criteria and indicators against which the reform will be evaluated have been defined ex ante. This requires foresight and budgets projected into the future at the time of the reform, which are often not forthcoming.
