Quality management in an audit firm: ISQM 1 and ISA 220 (Revised)

Audit quality does not depend only on the skill of one auditor: at firm level there is an eight-component system (ISQM 1), and at the level of each engagement the engagement partner's responsibility (ISA 220). Tables and practical situations using a hypothetical small audit firm.

"Pishtoq Audit" LLC is a small audit firm: two partners and eleven staff. Three things happened in one week. A new client offered a fee twice the usual and asked for the report "quickly". An experienced manager resigned, and two of his engagements passed to a new staff member. And an internal inspection found that one audit file from last year did not record the reason for a significant change to the plan. All three situations come down to one question: how does the audit firm manage audit quality?

Conditions: the audit firm, names and situations are hypothetical, compiled by the author.

In Uzbekistan the international standards on auditing are the standards of auditing activity (Law "On Auditing Activity", Article 9). The International Auditing and Assurance Standards Board (IAASB) regulates quality at two levels: at firm level ISQM 1, at the level of an individual audit engagement ISA 220 (Revised). Engagement quality reviews are governed by a separate standard, ISQM 2.

How do firm level and engagement level differ?

Application datethe system had to be designed and implemented by 15 December 2022audits of periods beginning on or after 15 December 2022

Which eight components make up ISQM 1?

ISQM 1 applies a risk-based approach: the firm sets quality objectives, identifies the risks that threaten them and designs responses. The components operate in an integrated way, not in sequence. For six components the standard sets mandatory quality objectives; risk assessment and monitoring are structured as processes.

ComponentContentExample at "Pishtoq Audit"

2. Governance and leadershipleadership's commitment to quality, allocation of responsibilities and resourcesa partner responsible for quality has been appointed; bonuses depend not only on revenue but also on quality
3. Relevant ethical requirementscompliance with independence and other ethical requirementsat the start of every engagement staff complete an independence declaration
4. Acceptance and continuancethe decision to take on an engagement or nota double fee and a demand for "a quick report" are assessed as a risk indicator
5. Engagement performancedirection, supervision, review, consultation, resolving differences of opinioninternal consultation on a complex matter is mandatory, its outcome is recorded in the file
6. Resourcespeople, technology, intellectual resourcesthe departed manager's engagements were moved under the supervision of an experienced partner
7. Information and communicationobtaining and communicating the information the system needsa monthly internal bulletin on changes in standards
8. Monitoring and remediation processchecking that the system works, finding the cause of a deficiency and fixing itcompleted files are inspected on a sample basis; training was held on the deficiency found

The individual(s) assigned ultimate responsibility for the system evaluate it at least annually and conclude whether the system provides reasonable assurance that the quality objectives are being achieved. The first evaluation had to be performed within one year after 15 December 2022.

What does ISA 220 require at engagement level?

The revised ISA 220 defined the engagement partner's role more precisely. The engagement partner takes overall responsibility for managing and achieving quality on the audit engagement and is sufficiently and appropriately involved throughout the audit. The standard also contains a final "stand-back" requirement: at the end of the audit the engagement partner determines that this overall responsibility has actually been taken.

This applies directly to the second event at "Pishtoq Audit": the manager leaving does not release the engagement partner from responsibility. On the contrary, the partner must review the new staff member's work more.

What is an engagement quality review?

For some engagements the firm adds an extra layer of protection: a specialist who did not take part in the engagement objectively reviews the significant judgments and conclusions. The appointment, eligibility and responsibilities of the reviewer are set out in ISQM 2. Which engagements need such a review is determined by ISQM 1 and the firm's policy.

How the three situations were resolved

SituationWhich component or requirementWhat the firm did
Double fee and "a quick report"acceptance and continuance; ethical requirementsthe partners renegotiated the terms with the client, the deadline was matched to the scope of the audit; otherwise the engagement would not have been accepted
An experienced manager resignedresources; engagement partner involvement under ISA 220the engagement partner started reviewing the new staff member's work every week
The file did not record the reason for a change to the planmonitoring and remediationthe cause was investigated (the template had no dedicated section), the template was supplemented, short training was held for the team

How does this help the client company?

When choosing an auditor, you can look not only at the price but also at the firm's way of working: who the engagement partner is, how involved they are in the audit, whether there are internal consultations on complex matters. A firm that answers these questions clearly usually works in an orderly way.
