Particularly in the current economic climate, your company may ask you to find opportunities for lean improvement in your department or area, so that you can deliver the same value to the customer at lower cost to your organization.

One option is to put more resources into physical inspections. But will that solve the problem, or will it just add cost to a process that's flawed somewhere else?
Process improvement is successful only when you address the underlying problem. A useful way of improving processes successfully is to use a lean manufacturing technique called Value Stream Mapping (VSM). It originated at car manufacturer Toyota, where they called it "material and information flow mapping." Mike Rother and John Shook then developed Toyota's ideas in their 1999 book, Learning to See, creating Value Stream Mapping. VSM is now widely used in a variety of industries as a way of identifying improvement projects.
The basic idea behind Value Stream Mapping is this: ...
