From order to invoice
How many days sit between completed work and the invoice sent, and why.

PROCESS IMPROVEMENT · LEAN · SIX SIGMA
In every SME there is time between the work and the money. A job sheet sitting on a desk. Data typed in twice. An invoice that goes out when someone remembers. Nobody is doing anything wrong, the process simply grew that way. ETTAI measures where the days disappear and takes them out, together with the people who do the work.
