Dimensional Management
Contechs provides a managed DM/DVA (Dimensional Management/Dimensional Variation Analysis) service to improve the quality of design and reduce the cost of manufacture by managing and controlling variation.
Phase	DM/DVA deliverable

Pre-concept	Advise on styling guidelines D.M. Planning Competitor benchmarking Competitor benchmarking Identification of constraints Document dimensional objectives

Concept	Develop design alternatives Develop assembly alternatives Define initial locating schemes/sequences for assembly process Define initial datum schemes, GD & T. Indicative results on optimum strategy

Design	Refinement/Optimisation Supplier tolerance liaison Product documentation Change control Gateway status reporting (inc. problem resolution) DVA model updated to include surrogate capability Define measurement plan Develop list of critical characteristics VA prediction input to all Level 3 & 4 measurement points

Validation	Verify tooling and gauge design Conduct gauge repeatability and reproducibility studies Validate assembly tools Perform capability studies Measure 1st off tools Functional evaluation Variation reduction Validate manufacturing capability meets design intent

Launch	Data gathering -SPC (Statistical Process Control) Root cause analysis Comparison of actual values to predicted feedback of measurement of manufacturing noise Capturing lessons learned
