When using the parametric module 4cost-aces to estimate the costs for components, assemblies (mechanical and electrical), software, design, and overall integration, the results are very dependable and traceable. The calculated results are split into cost categories for development, prototyping, tooling & test, and production. In addition to component costing, various economic scenarios can also be compared. Target costing can be tracked using the module 4cost-structure. Transparency and traceability are always our focus. Cost drivers are identified and countermeasures can be initiated. These actions assure successful target costing and minimize the potential for cost overruns. Changes in design, done in early phases of a development project, are not as costly as those done when entering production. Now is the time to use the 4cost-value-revolution package to optimize product and system costs efficiently and in a timely manner, before entering the market.
