Development of new forming processes aims for overcoming the current process limitations so that function extended components with a wider range of application and lower manufacturing costs are producible. But the comprehensive and complex investigations of cause-effect relationships and interdependencies in the development lead to an intransparent development status, whose assessment is often based on undefined and not reproducible criteria. This can result in wrong decisions with vain modifications that require subsequent changes associated with an increased effort. A valid characterization of the development status is needed to identify improvement potentials in early development phases and thus to apply the effective measures with reduced efforts. Maturity models provide essential indicators and assign their values to maturity levels, whereby a uniform assessment base is created to identify the development status reproducibly. Currently there is neither a maturity model for the assessment of new forming processes in development available nor a method-based procedure for the design of specifically needed maturity models. Therefore, a systematic approach has been designed to be able to determine maturity-related indicators on the basis of a combined reference model. The indicators are to be subsumed, weigthed and provided in a maturity-levelmatrix. This approach has been applied within the development of the novel Sheet-Bulk Metal Forming which aims for uniting the advantages of sheet and bulk metal forming processes. The designed maturity model for new forming processes facilitates the assessment of the development status with referencebased indicators and provides more transparent results in comparison to subjective evaluations.
