Sooner or later, you will need an Audit Plan when conducting internal audits. An Audit Plan is an important step not only for organizing the audit team but also for minimizing disruption to your organization’s operations. Markdown colado
As a document designed to organize audit activities, it establishes the audit schedule, identifies the processes and areas to be audited, defines start and end times, and assigns auditors, among other important details.
An effective Audit Plan should anticipate the processes, people, resources, and time needed for the audit so that the audit team can work efficiently without overlooking relevant processes.
It also helps align expectations. For this reason, the Audit Plan should be communicated sufficiently in advance so that the areas involved can prepare. Employees should know when their processes will be audited and what participation may be required.
In this article, we’ll explain what an effective Audit Plan should include, which factors can affect its development, and which common planning mistakes should be avoided.
ISO 19011 – Guidelines for Management System Auditing
When developing an Audit Plan, ISO 19011 is an important reference because it provides guidelines for auditing management systems.
The standard provides guidance on managing audit programs, conducting management system audits, and evaluating the competence of individuals involved in the audit process.
Its guidance can therefore support the development of an Audit Plan by helping determine what will be audited, which criteria will be applied, which processes need to be covered, and how audit activities will be conducted. Markdown colado
An Audit Plan should be understood as more than just a schedule.
It should serve as a roadmap for achieving adequate audit coverage while considering the processes and applicable requirements that need to be evaluated.
At the same time, effective planning should help minimize unnecessary disruption to the organization’s normal operations.
What Should an Audit Plan Include?
When developing an Audit Plan, several fundamental elements need to be considered. These elements provide the basic structure needed to organize audit activities effectively. Markdown colado
Audit Objectives
Clearly establish what the audit is intended to accomplish and what aspects of the management system or processes need to be evaluated.
Audit Scope and Criteria
Define the boundaries and extent of the audit and establish the requirements against which audit evidence will be evaluated.
Audit criteria may include management system standards, internal procedures, policies, statutory and regulatory requirements, contractual requirements, or other applicable references.
Schedule, Locations, Dates, and Times
Identify the sites, facilities, or locations that will be audited and establish when each audit activity will take place.
A detailed schedule helps both auditors and auditees prepare appropriately and ensures sufficient time is allocated to relevant activities.
Audit Team
Identify the auditors responsible for conducting the audit while considering the competence required to evaluate the processes and activities included within the audit scope.
When there is more than one auditor, responsibilities should be clearly assigned.
Processes and Responsible Personnel
Identify which processes will be audited—such as purchasing, receiving, warehousing, production, shipping, administration, or other applicable processes—and determine who is responsible for each one.
Opening and Closing Meetings
Allocate appropriate time in the audit schedule for opening and closing meetings, including when and where they will take place.
Language and Interpretation Requirements
For multinational or multilingual organizations, determine the language or languages in which the audit will be conducted.
When necessary, determine whether an interpreter or other language support will be required to ensure effective communication.
Audit Methods
Determine whether audit activities will be conducted on-site, remotely, or through a hybrid approach.
The selected methods should consider the nature of the organization, the processes being evaluated, available technology, associated risks, and the feasibility of conducting the audit effectively.
Audit Sampling
Audits are generally based on sampling rather than examination of every available record, transaction, or activity.
When applicable, the Audit Plan can provide information about the planned sampling approach and considerations used to determine appropriate samples.
What Should You Consider When Developing an Audit Plan?
Another common question is: How detailed should an Audit Plan be?
There is no single level of detail that works for every organization.
The appropriate level will depend on several factors related to both the organization and the specific audit being conducted. Markdown colado
Management System Complexity
The more complex the management system, the more detailed and structured the Audit Plan may need to be.
Consider the number of processes, how those processes interact, applicable management system requirements, and any justified non-applicability of requirements.
Number of Employees
The number of employees can affect the amount of audit time needed.
Organizations with larger workforces or processes involving many employees may require additional time for interviews, sampling, and observation.
Number of Shifts
If an organization operates multiple shifts, consider whether audit activities need to cover different shifts.
Operational conditions may vary considerably between shifts, making appropriate audit coverage important.
Multiple Sites
For multi-site organizations, determine which locations need to be audited and how site sampling will be addressed based on applicable requirements and the characteristics of the management system.
The Audit Plan should also consider the logistics associated with auditing multiple locations.
Previous Nonconformities
Results from previous audits are another important planning input.
When there is a significant history of nonconformities, sufficient time should be allocated to evaluate not only whether the issues were addressed but also whether the corrective actions taken were effective.
Recent Organizational Changes
Recent changes involving processes, organizational structure, facilities, personnel, technologies, or other significant areas should also be considered during audit planning.
These changes may introduce new risks or require additional audit attention.
Common Mistakes When Developing an Audit Plan
Understanding common planning mistakes can help prevent problems during the audit itself. Some of the most important issues to avoid include: Markdown colado
Allocating Audit Time Incorrectly
Poor time allocation can leave auditors without enough time to adequately evaluate important processes while unnecessarily allocating too much time to others.
Audit time should therefore be distributed carefully according to the scope, complexity, risks, and activities being evaluated.
Forgetting Processes or Departments
Make sure all relevant processes and departments are appropriately considered.
For example, if the organization recently created a Product Development department but the process is accidentally left out of the audit planning, an important part of the management system may not receive appropriate audit coverage.
Ignoring Audit Logistics
Consider all logistical aspects involved in conducting the audit.
For a multi-site organization, for example, the Audit Plan may need to account for travel time between different facilities.
Ignoring these practical considerations can compromise the audit schedule.
Poor Coordination Among Auditors
When an audit involves multiple auditors, clearly determine how responsibilities and audit time will be distributed.
For example, establish whether activities will be audited simultaneously, whether individual auditors will be assigned to specific processes or management system standards, or whether certain activities will be conducted jointly.
Failing to Consider the Audit Scope
The audit team must clearly understand and respect the defined audit scope.
If the scope is not properly considered, important processes may be overlooked, activities outside the scope may be unnecessarily audited, or requirements that are not applicable to the audit may receive inappropriate attention.
Audit Plans: More Than Just a Schedule
An Audit Plan is much more than a timetable showing what will be evaluated.
It should facilitate effective communication and provide the audit team with a clear roadmap for achieving appropriate coverage of the applicable criteria, requirements, processes, and organizational areas. Markdown colado
When properly developed and communicated, an Audit Plan helps prevent surprises and ensures that everyone involved understands what to expect.
It also supports appropriate audit coverage by helping auditors evaluate the relevant departments, areas, and processes against the applicable requirements.
Ultimately, developing an effective Audit Plan requires careful consideration of the organization’s context, processes, applicable requirements, previous audit results, changes, risks, and practical constraints.
A well-designed Audit Plan does more than organize an audit: it provides direction, supports appropriate coverage, improves communication, and contributes to a more efficient, objective, and reliable audit process.
