History
1940–1950
PA was founded in 1943 as Personnel Administration by Ernest E. Butten, Tom H. Kirkham and Dr David Seymour. Britain's war effort created great demand for munitions and goods, which had to be produced by a relatively unskilled workforce. Butten and his colleagues formed Personnel Administration Limited to provide advice to industry as to how to improve the productivity of their workers.

During the Iraq War, PA developed the "Panama System" to protect UK troops from improvised explosive devices, winning the Management Consultancies Association's top prize for innovation.

More recently, the Centre designed a prototype electric vehicle charging point that aims to be “as recognisable as the red post box or black cab” with the Royal College of Art for the UK Government; developed the manufacturing equipment needed to mass produce
edible water bottles for Notpla; and helped build the world’s biggest battery in California with Vistra Energy.
