PA Consulting Group

London innovation and transformation consultancy founded in 1943 as Personnel Administration, and once the world's largest management consultancy. It was the Ministry of Defence's programme partner on Panama, the 2010–11 urgent operational requirement that turned surplus Snatch Land Rovers into remotely operated IED-detection vehicles for Afghanistan.

History

PA was founded in 1943 by Ernest E. Butten, Tom H. Kirkham and Dr David Seymour as Personnel Administration, applying new methods of people management to raise output in wartime munitions factories. It grew into a broad management and technology consultancy — by 1970 the world's largest by headcount — and has an unusually long history of employee ownership: Butten gave his entire holding to the Butten Trust in 1958, and after a spell as a listed company in the late 1980s the firm returned to staff ownership in 1992. The Carlyle Group took a majority stake in 2015 at a valuation of about US$1 billion; Jacobs bought 65 per cent for £1.825 billion in a deal completed on 2 March 2021, Carlyle exiting, and Wikipedia records Jacobs subsequently acquiring the remaining employee shares. The firm is headquartered in London with offices in some nineteen locations, and reported revenue of £752.9 million and 3,895 employees for 2024.

PA is not a vehicle builder. Its place in this registry is as programme partner to Defence Equipment and Support on Panama, the urgent operational requirement of 2010–11 that converted redundant CAV-100 'Snatch' armoured Defender 110s into remotely operated route-proving vehicles for Helmand province. Each carried a ground-penetrating radar on an articulated boom ahead of the vehicle and worked at the head of Royal Engineers Talisman route-clearance groups, driven by remote control from inside a Mastiff. The conversion contract itself went to MIRA, which fitted its MACE remote-control system, with Thales UK and Exponent supporting integration; PA ran the programme, which moved from investment decision to operational use in eleven months and came in around £9 million under a roughly £50 million budget. The work won PA the Management Consultancies Association's top award in 2012, and the company's own account describes the Panama System as protecting UK troops from improvised explosive devices.
