Outputs Value = Product or Service Heat Waste materials Systems View Inputs: Raw matrls Consummables People Energy Building Enterprise
Background • 3 companies, component manufacture, engineering and medical device industries • Carten Controls • Frentech Engineering • Lake Region • Range from 50 to 700 employees • Multi-national & indigenous • All had commenced implementation of Lean Principles Grant aided under EPA’s Cleaner Greener Production Programme
Approach • Further lean training • Use modified VSM • Overlay energy & material inputs and outputs & effluents onto Value Stream Map • Energy & Effluent pro-rata with what?
Examples of improvements • Right-sizing process to throughput: • Reduced EP rinsing, rightsize to qty of valves, 60% reduction in water usage • Reduce cleanroom energy inputs, 50% red’n in electricity • Design modifications • Minor change to valve design to make heat mark removable by hand-buffing, 50% red’n in EP usage • Challenge design of chamfers, 34% red’n in swarf • Change design from welding to riveting, eliminates airborne dust, extraction and some safety issues
Examples contd… • Other • Grinding Coolant, separate supply when dressing wheel • Administrative & engineering processes: • Lean lines require less routers, 80% red’n in paper • Eliminated steps in quotation & purchasing process • (Logic=change information or simply copy it?)
Advantages of the VSM Tool • More useful in the bigger companies because the process is harder to see in its totality • Supports “whole-system thinking” rather than sub-optimisation • What gets measured, gets done • Promotes “why-why-why” analysis
Conclusions So Far… • Yes; Lean = Clean & Green • Must look at entire system, rather than suboptimise • Use process maps, inputs & outputs & drivers to expose waste
