In the case of the cost management itself, you can also indicate the existence of a similar dependency system. Their exact determination is connected with the establishment of similarity parameters, which will allow estimating the costs of new production orders based on previous experience. It must also refer to the existing machinery park. For example, if mediumsized elements have been implemented so far, the new order includes elements with large dimensions, then you need to have indicators

... estimate the possible increase in costs related to the change in dimensions. Accurate estimation of this type is possible only on the basis of indicators obtained experimentally and determining the appropriate way to extrapolate them. The present study presents only the technological part of this process related to the determination of technological parameters, as a comparison for a narrow, but very specialized technological group, which are gears. The comparison of basic technological processes was taken into account. The purpose of these preliminary, basic studies was to obtain information on the estimation of gear machining costs, for new types of tools and new machining positions, which in some situations can be treated as an alternative. In order to avoid errors in the planning phase are being sought techniques that are appropriate to manage the project. Application of the proper project management methodology leads to increasing the likelihood of success and achieving significantly better results at a lower cost, less effort and in shorter time.
