Samenvatting

Large government investments are regularly preceded by an ex-ante evaluation. This article examines the quality of two ex-ante studies and considers the use made by administrators and representatives of the people of these ex-ante studies. In both cases it concerned qualitatively sound ex-ante studies. In both cases, these studies also demonstrably affected the debate about these investment plans in the people’s representations. But there was no question of power-free decision making. In both cases, the representatives of the people were put under great pressure. Not only was there time pressure. The public debate came late. The use of sound ex-ante studies is not only an investment in rationality, but is also accompanied by political-strategic manoeuvring. The relevance of this article to practitioners is that it (a) contains four reasonable requirements that the representative may make of each ex-ante study offered by the executive board; (b) also shows that an ex-ante analysis on which important decisions are based should not be characterised by secret parts or by undefined assumptions and an ex-ante analysis must be transparent; and (c) demonstrates it is important as a representative to be tenacious, to keep a firm hand and not to decide before all questions have been answered and a full list of safeguards is on the table.
