A self-proclaimed expert that extorts inflated fees from a host company in return for vague and predominently incorrect business advice.
The successful consultant detaches from its host at the exact moment its parasitic qualities are discovered by upper management. Thus, the successful consultant's term of engagement will last from months to years, until a mildly attentive decision-maker realizes that their burning ray of hope is all talk. Note that some middle managers and all other employees of the host will immediately recognize the consultant as a pathogen.
In order to gain access to a viable host, the consultant preys upon upper managements' lack of job expertise and unrealisistic dreams of grandure.
