About Value Analysis

Matrix of Design Elements (System Elements) to Functions. Documents contribution of Design Elements to Functions.

The Value Analysis component adds Target Costing, Bill of Materials and Function Costs to the DFSS cycle.

Worksheets

The Bill of Materials Worksheet

The Bill of Materials is a table showing different kinds of costs for each component or part. The parts in the list depend on the concept selected in the left upper corner of the worksheet. All calculations and results relate to the selected concept. For editing and analyzing the different types of costs, 3 sub-worksheets are provided:

  • Concept Costs: Zeigt die unterschiedlichen Kostenarten für jedes Konzept

  • DE Target Costs: A table of target costs related to the available or used components and parts

  • FR Target Costs: A table of target costs related to the product functions implemented by the design elements. The values in this table are calculated from the design elements target costs table using the QFD3 (Design Elements vs. Functional Requirements) matrix.

    Design Elements
    DE - Design Elements: Tree of components (parts, units, subsystems) at the system level and measurable component characteristics (design parameters) at the detailed design level. Measurable component characteristics can be marked as parameters.
