Cracking the performance code: executive summary is based on the second phase of our research into organisational performance. It explores the drivers that lead to improved performance, and what organisations can do to improve their performance. Nearly 3,000 firms of all sizes and from all sectors were surveyed and ranked in a Company Performance Index (CPI). The results show that in terms of added value, the top third of firms out-perform the bottom two-thirds by £1,600 per worker per year. It is relevant for chief executives, HR professionals, managers, chief finance and operating officers, other employees, and policy-makers.
