John Bloor, the entrepreneur who revived Triumph, recently commissioned management consultants McKinsey to perform a strategic review of the company. The review was triggered in part by a fire that destroyed most of Triumph's Hinckley factory in March last year, although the factory and its 650 employees were back in production by September.

"I will be disappointed if Triumph does not increase its sales and production by 25% a year over each of the next five years," Tue Mantoni, a member of the McKinsey team who recently became Triumph's commercial director, told The Financial Times newspaper.

It is suspected that Bloor has invested more than $140 million in the Triumph venture, most recently to re-equip with the latest generation of computer-aided design and engineering equipment, and flexible manufacturing processes. He acquired Triumph’s intellectual property rights from liquidators 20 years ago.
