About Contract Manufacturing Index
The Contract Manufacturing Index (CMI) has been developed to reflect the total purchasing budget of companies that are looking to outsource subcontract manufacturing of custom made parts in any given month.
This reflects a sample of over 4,000 companies, who have a purchasing budget of more than £5bn and a supplier base sample of over 7,000 vendors, with a verified turnover in excess of £25bn.
We measure this by extracting data from the projects we receive from manufacturing purchasers who have an active need for the services of subcontract engineering suppliers.
Since 2016, we have published the index quarterly and this report is a summary of our findings for the this current quarter. In order to shed more light on the emerging trends, we have also broken this down by process and industry.
