Come to think of it, in reality, it is not a hush hush secret if a consultancy is offering services to a firm. Most times it is in the public space.I bet it would not require the CIA to know which firms have engaged Mckinsey, BCG, Accenture, Capgemini, AT Kearney etc. Some of this firms even announce it without the press needing to dig, so I really cannot comprehend this need for secrecy about client name.Details and methods of engagement at the client I can understand the need for secrecy but not (most times) the name of client.
