A rapid expansion ensued followed by a move to Sunley House in Croydon and offices being opened in the Netherlands in 1969 and later in Germany.

This acquisition brought several new locations to its UK business and, when merged with the existing Croydon based bureau operation, formed the basis of CMG's growth in Outsourcing and Managed Services throughout the 1990s.

This created a policy of management that depended on CMG Group growth, whereby aspiring directors from the consultancy ranks could be nominated by their MD to take an internal course that was also an assessment.

Groups of companies were divided into Sectors; these were Finance, Insurance, Telecoms, Transport&Industry, Utilities, Commercial (Oil&Gas), Public and Managed Services.

[6] It has been agreed that the unusually high price for Goodwill (accounting) spent by CMG on Admiral was the indirect cause of the Logica merger[citation needed], as the cash position of CMG became compromised the next year when an economic downturn in the Netherlands caused an internal upheaval and later layoffs.

[7] CMG supplied services and products in the finance, trade and industry, transport, telecommunications, energy and public sectors.

The Company also provided managed information processing services, including networks, payroll and personnel.

CMG created its own quality system that it successfully used to gain ISO 9000 accreditation, called 'Commander', which included a Waterfall model of software project management.

One of the most popular applications which it developed and sold for decades, was PAYFACT, a payroll and HR reporting system that gained widespread use in the Netherlands in the 1990s.

Commander's added value as a quality system over the years was thus improved and adjusted through proprietary use, as well as from projects for customers or industry standards.
