PC-based industrial automation human-machine interfaces (HMI) and supervisory control and data acquisition (SCADA) software packages have been around since the 1980s, with significant growth occurring when Microsoft introduced Windows in the mid-80s.

Dashboard screens typically show an overview summary of plant or facility operations and include business intelligent information such as key performance indicators (KPIs).
