There is no shortcut on quality control process: the Zen Plus rewards preparation and punishes improvisation.

Where two suppliers look identical on price, quality control process is usually the variable that separates them over a full year.

Why quality control process matters on the Zen Plus

Incoming inspection sampling catches most issues before they reach shops.

Cash flow is the quiet constraint behind quality control process: the cheapest option is rarely the one that frees the most working capital.

Functional testing of a sample from each batch is standard practice.
