In conjunction with Nottingham Business School, MT asked Britain's 10 largest public companies in 24 sectors to evaluate their peers. Using nine criteria, participants rated their nine sector rivals on a scale of 0 to 10 (0 = poor, 5 = average, 10 = excellent). Analysts at leading City investment firms were also polled.
On the basis of these scores, three rankings were arrived at: all 240 companies (above); top five overall on each criterion (p37); and league tables in each sector (pp41, 43, 45). In sectors where there are fewer than 10 qualifying 'pure' UK companies, selected international businesses with significant operational presence and revenues in the UK have been included.
Respondents were also asked to name the leader they most admired.
Research was conducted by Prof Michael Brown of Nottingham Business School and Stuart Laverick.
