A configuration tool adapted to configure a quality control system to monitor and/or guide an operator in a working environment through recognition of objects, events or an operational process, said configuration tool comprising: A. a volumetric sensor adapted to capture volumetric image frames of said working environment while an object, event or operational process is demonstrated; B. a display, coupled to said volumetric sensor and configured to live display said volumetric image frames; and C. a processor configured to: C1. generate a user interface in overlay of said volumetric image frames to enable a user to define a layout zone; C2. automatically generate a virtual box (133, 134) in said layout zone when an object, event or operational process is detected during demonstration of said object, event or operational process; and C3. select a precision parameter for said virtual box (133, 134) to be used to detect presence/absence of an object or event in said virtual box, said precision parameter being one of: - a fill level; - an occlusion level; - a standard deviation; or - another parameter describing a change in a virtual box, wherein the parameter with highest difference between subsequent volumetric image frames during demonstration of said operational process is selected as precision parameter.
