PCAOB Adherence

Problem
In April 2010, the PCAOB issued a disciplinary order instituting disciplinary proceedings, making findings, and imposing sanctions in the case of Robert T. Taylor, CPA (both the firm and the individual auditor). The order can be found in PCAOB Release No. 105–2010–006 at www.pcaobus.org. (Review the PCAOB Web site, access this release, and answer the following questions.)
A) The order in the case of Robert T. Taylor recognizes that PCAOB standards require that an auditor exercise due professional care, exercise professional skepticism, and obtain sufficient evidence on which to base an opinion on the financial statements. Describe instances in which the respondents in the order did not adhere to these requirements.
B) Why is adhering to these professional requirements important for audit quality?
