Andrew Hill has been a director/consultant in Ventana Systems UK since 2000. Prior to co-founding Ventana System UK, Andy spent 10 years as a defence analyst, working across a broad spectrum of projects, from manpower recruitment & retention to a complete tri-service analysis of the UK defence equipment requirements.

Whilst with Ventana, Andrew’s focus has been within the health & pharmaceutical sector, evaluating demographics of drug utilization trends from national prescription databases, patient flow analysis and international drug pricing strategies.

Andrew delivers Vensim/SD workshops to both commercial and academic organizations to teach others the System Dynamics methodology and advanced application of the Vensim software suite

His systems approach to tackling problems allows him to concentrate on the important & practical issues, and not be side tracked by issues not central to the problem solving requirements.
