The governing factor on where a consultant works tends to be the amount of interaction required with other employees of the client. If a management consultant is providing advice to a software firm that is struggling with employee morale, absenteeism and issues with managers and senior engineers leaving the firm, the consultant will probably spend a good deal of time at the client's office, interviewing staff, engineers, managers and executives, and observing work processes. Accredited Associates are bound by a Code of Ethics that require the consultant to only provide “practical advice that works”—“Analysing as a Generalist and Solving as a Specialist”—by using the skills and experience of a sub-contracted fellow Associate, thus at all times providing the client with the best available advice and support. Internationally the accreditation of Management Consultants is overseen by higher education training and accreditation organizations. Consultant Peter Block defines a consultant as "someone who has influence over an individual, group, or organization, but who has no direct authority to implement changes." He contrasts this with a surrogate manager who is a person who "acts on behalf of, or in place of, a manager." The key difference is that a consultant never makes decisions for the individual or group, whereas a surrogate manager does make decisions.
