STEP 1
The engineering approach to cost estimation is based on the least cost available technology needed to achieve a given level of abatement.

In practice the engineering approach estimates cost by doing a detailed analysis on an industrial engineer's evaluation of the inputs that are required to carry out a particular activity and of the prices of those inputs. From the practical point of view this approach is modified to have a broader user base with greater differences between the user and designer in terms of skill & experience. Moreover the components related to usability are estimated independently by specialized team. They focus on the persons who use ...
