7. Evaluation of control in critical systems
o Identify controls in the system or systems relating to
each audit issue.
o Determine if these controls are reasonably adequate
with reference to the organizational objectives.
o Identify any unusual activities or specific weaknesses,
or other risks, which need to be addressed.

8. Ascertain and record
Identify controls in critical systems
Identify management objectives
Define control objectives
Record control objectives

9. Compliance testing
The objective of compliance testing is to get assurance that
the internal controls on which the auditors have decided to
rely had been in place throughout the period of audit.
Sampling for compliance testing
Sample size for compliance testing depends on:
 Upper Error Limit (UEL)
 Expected number of deviations in the sample
 Confidence level to be obtained from audit procedures
Formula for calculating sample size
CF
SS =
UEL

10. Compliance test program
 Specify its overall objective.
 List the tests the auditors should perform along with
the test technique.
 Be drawn up for controls of each audit issue to be
evaluated.
 Have its tests cross-referenced to the specific controls
in the control framework evaluation.
 Be revised after any major change in controls.
 Tests only key controls.
 Specify what is meant by a control failure.
 Specify when tests are to be performed.
 Specify the sample size and the length of observation
period. DR MUHAMMAD TAUSEEF

11. Direct substantive testing
Substantive procedures involve the use of Analytical
Procedures and Substantive tests of details.
ANALYTICAL PROCEDURES
These are techniques by which the auditors:
o Study and use meaningful relationships among
elements of financial and non-financial information to
form expectations about what the recorded amounts
should be.
o Compare such expectations with the recorded amounts.
o Use the results of the comparisons to help determine
what, if any, other audit procedures are needed to obtain
reasonable assurance that the recorded amounts are not
materially misstated.

12. Types of analytical procedures
o Reviews for reasonableness
o Comparative analysis
o Predictive analysis
o Statistical analysis
o Overall verification procedures

13. Substantive tests of details
- 100% for very large transactions
- 100% for high risk transactions
- On sample basis for remainder
Objective of test

o Completeness o Completeness
o Existence o Occurrence
o Valuation o Measurement
o Ownership o Compliance with authority
o Disclosure o Disclosure

14. Methods of testing
- Physical verification
- Re-performance
- Independent third party confirmation
- Scrutiny
- Vouching
- Inspection

15. Sample size for substantive test of details
Monetary Unit Sampling
Formula:
PV x CF
SS = , where
BP
SS = Sample size
PV = Population value
CF = Confidence factor
BP = Basic precision (One half of materiality amount)
