The
RAM as a tool is very comprehensive. One key inherent characteristic it
possesses is its ability to generate paper trails at virtually every stage of
the auditing process. The implementation of the RAM involves four audit
regulatory processes. These are: (1) Planning; (2) Strategic Audit Planning;
(3) Audit Execution/Fieldwork; and, (4) Reporting. Since the execution of the
RAM follows a process, it can thus be inferred that the regulatory process, Audit Execution/ Fieldwork, cannot and would not occur before the Planning regulatory process. Each of
these regulatory processes shall be dealt with in more detail.
1. Audit Planning
It must be noted that
this particular regulatory process first and foremost covers assessment of
competency of audit team members as well as to ascertain whether the audit team
has the time to perform the audit. Any identified training needs are addressed,
where practicable, before the commencement of the audit. Specific competency
facets that are reviewed in relation to knowledge are: Understanding of the
audit approach and documentation; Involvement in prior year’s audit and
management letter issues; Legislation and regulations relevant to the audited
entity; Understanding of the systems and processes of the auditee; Financial
Reporting framework: Basis for the preparation of the financial statements
(e.g. Modified Cash accounting); IT systems and computerized environment.
Competency in the aforementioned is necessary if the audit process is to begin
on a sound footing.

The second
consideration under this regulatory process is to assess and
ensure that any threats to the audit team member’s independence have been
eliminated or reduced to an acceptable level. In a bid to ascertain their
ethical stance, prospective audit team members are subjected to a series of
questions bordering on ethical issues such as conflicts of interest,
independence, political neutrality, integrity, objectivity & impartiality,
professionalism and professional development.
Furthermore,
under this process, the hours required for the audit is budgeted for and then
compared against the actual. Hours for activities such as administrative
planning (e.g. code of ethics declaration, competency matrix etc.), planning
(e.g. internal control checklist, regulatory framework, planning materiality,
risk of material misstatement etc.), fieldwork (e.g. system description,
reliance on key controls, performing substantive tests, audit observations etc.) and reporting (e.g. audit differences,
management letters, audit report etc.) are budgeted for. Additionally, to
enhance division of labour, responsibilities for the execution of different
audit-related activities are assigned among team members and agreed to in
writing. Finally, as a way of assessing the quality of the panning process,
audit team members are subjected to some quality control questionnaires so as
to ensure that none of the regulations guiding the audit planning process has
been flouted.
2. Strategic Audit Planning
The
second process in the RAM is the Strategic
Audit Planning and it entails understanding the business and operations as
well as the legal framework backing the auditee entity, thus allowing for a
thorough assessment of material risks. The control framework of the auditee
entity is also reviewed with the aid of an internal control checklist, thereby
enabling the determination of the audit approach to be used. Furthermore, it is
during this process that the overall audit strategy is devised. Approval of the
audit plan is also sought during this particular process.
3. Audit Execution
This is the regulatory
process that ushers in auditing proper. It all commences with an Entrance
Conference to explain
the audit purpose, approach and strategy in a bid to establish communication
channels between the audit team and management. The audit execution is then
conducted following a number of component levels. These component levels are
lead schedule; system description; release on key controls; test of controls to
determine if there are any irregularities; and performance of substantive
testing. Finally, test controls are evaluated.
4. Reporting
Here, audit completion
procedures are performed and the appropriate audit opinion formed. Audit report
is then put together and submitted to the Auditor-General who then reviews it
and forward it to Parliament.
