Keperlsky and Bennuchi, and audit firm was auditing EDJ consulting. EDJ is a large consulting firm that has consistently had very strong internal controls over IT functions at the company. The company uses SAP, a sophisticated, Tier 1 ERP system that has not been customized. Keperlsky and Bennuchis audit team has reviewed and tested the internal controls and concluded that the controls are very effective (strong) and they can be relied upon. Mr. Keperlsky, a partner, has said that it is not necessary to complete substantive testing in this case, given the strength of the internal controls and a strong ERP system. Is Mr. Keperlskys conclusion correct? Provide justification for the answer.
