A nonaudit client requests assistance of M. wilkenson,CPA , in the installation of a local area network. Wilkenson had no experience in this type of work and no knowledge of the client's computer system, so he obtained assistance from a computer consultant. The consultant is not in the practice of public accounting, but Wilkenson is confident of his professional skills. Because of the highly technical nature of the work, Wilkenson is not able to review the consultant's work.
