Q

What are advantages and disadvantages of flowcharts? Meaning of specific symbols?

A

A systematic approach that prevents overlook important considerations, fairly easy to review/understand/update. Tailored to client specific.

Tedious/time consuming. Might miss deficiencies by too much details.

Square: computer operation/process. Square w/wave bottom: document. Square with narrowed bottom: manual operation (off-line). Diamond: decision point. Triangle point down: Off-line storage (filing).

Q

What are advantages and disadvantages of ICQs?

A

Can be prepared in advance - prevent missing important questions. No answer indicates deficiency - easy.

Generic questionnaires not tailored to client - irrelevant questions can be included. Client could inaccurately answer intentionally/unintentionally.

Q

What are advantages and disadvantages of narrative write-ups?

Q

What is walkthrough?

A

Q

What should the auditor do if internal control is perceived to be ineffective?

A

Assess the control risk at the maximum level (no reliance) and perform a wholly substantive audit approach by;

  • considering the possible types of errors/problems that could occur.
  • considering the kinds of procedures that would prevent/detect those.
  • determine whether such control is in place.
  • evaluate implications of any identified weaknesses.
