54 Different methods can be used to assess initial cost and the choice among them depends on the detail of the available data and of the evaluation itself. These methods can be classified in three different approaches:
55 )))
56 * (((
57 1) Top-down synthetic approach: when few and generic information is available, the estimation can be carried out by analogy with existing projects or by experts opinions;
58
59 2) Bottom-up analytical approach: when more and detailed information is available, the estimation can be carried out using the work (cost) breakdown structure;
60
61 3) Parametric approach: the estimation is carried out by analogy with existing projects but high quality data are needed.
