In-Process Quality Audits: Definition, Importance & Key Components

In-process quality audits are evaluations conducted during ongoing operations to ensure that production, service, or workflow standards are being maintained. In-process quality audits act like regular checks while cooking just as one tastes food mid-way to adjust seasoning instead of waiting until the dish is fully cooked, organizations monitor processes before final output to detect and correct deviations early.

These audits are critical because they not only prevent wastage but also enhance compliance and customer trust. According to McKinsey (2022), companies that adopt real-time quality checks reduce defect rates by 30–50%, directly lowering costs and improving delivery timelines. Furthermore, a Deloitte study (2021) highlighted that over 70% of manufacturers using in-process audits saw faster resolution of quality issues compared to relying solely on end-product inspections. By embedding these checks, businesses build a system of continuous improvement, risk mitigation, and accountability across teams.

What is an In-Process Quality Audit?

An In-Process Quality Audit (IPQA) is a systematic evaluation carried out during the production or service delivery stage, rather than after completion. Its key purpose is to ensure that processes, materials, and workflows meet predefined quality standards at every stage, preventing errors from progressing further downstream. By catching defects early, organizations reduce waste, rework, and customer complaints.

Difference from Final Product Inspections

Unlike final product inspections, which verify quality only after the product is completed, an IPQA continuously monitors steps throughout production. This proactive approach not only identifies errors but also provides insights into the root causes of variation in real time. A study by McKinsey shows that organizations using process-based audits achieve 20–25% faster defect resolution compared to those that focus only on end-stage quality control (McKinsey, 2020).

Role in the Broader QA Framework

Within the broader Quality Assurance (QA) framework, IPQA acts as a preventive control mechanism that strengthens overall reliability. It complements supplier audits, raw material inspections, and final product checks by ensuring that every stage contributes to quality assurance. Research by the American Society for Quality (ASQ) highlights that firms adopting in-process audits report a 21% improvement in customer satisfaction scores (ASQ, 2021).

An In-Process Quality Audit is a proactive tool designed to ensure quality at every production stage, making it more effective than relying solely on end-product testing. It plays a critical role in building consistency, reducing costs, and boosting customer trust. According to ISO, companies that embed in-process quality checks can reduce defect rates by up to 30% compared to those relying only on final inspections (ISO, 2021).

Why Are In-Process Quality Audits Important in Quality Assurance?

In-process quality audits are important in quality assurance because they strengthen prevention, reduce costs, and improve both compliance and customer outcomes.

• Detecting issues early: Problems are identified during production rather than after completion, reducing rework and scrap. The U.S. Department of Commerce highlights that every $1 spent on early defect detection saves up to $10 in rework and $100 in warranty claims (USDC, 2020).
• Supporting continuous improvement: Insights from in-process audits can feed into training, process redesign, and lean initiatives. Bain & Company found that firms applying such feedback loops achieve 15–20% higher operational efficiency (Bain, 2021).
• Enhancing traceability and documentation: Recording findings at each stage allows businesses to track where and when problems occur, improving compliance. Research shows that firms with strong in-process traceability reduce recall costs by 35% (IJPR, 2020).
• Driving real-world impact: Beyond compliance, the business case is strong—IBM reports that process-level audits lower quality-related costs by 18% and raise customer satisfaction scores by 12% (IBM, 2021).

In-process audits are not just checkpoints but continuous safeguards that improve efficiency, reduce risk, and deliver lasting value to both organizations and their customers.

What Is The Relationship Between QA and In-Process Audits?

The relationship between QA and in-process audits is that they work together as complementary pillars of a strong quality management system. Quality Assurance (QA) establishes the standards, policies, and frameworks for consistent output, while in-process audits ensure those standards are being followed in real time during production.

• In-process audits as part of QA: They are not separate from QA but rather an essential component, verifying that every step of production aligns with quality benchmarks. A report by ISO shows that organizations combining QA frameworks with in-process audits reduce defect rates by 25% compared to those relying solely on final inspections (ISO, 2020).
• QA sets the standards, audits verify compliance: QA outlines requirements, documentation, and performance metrics, while audits act as checkpoints to ensure adherence. According to a study in the Journal of Manufacturing Systems, firms integrating audit verification into QA saw a 30% improvement in compliance rates (JMS, 2021).
• Audit findings drive QA improvements: The results from in-process audits provide actionable feedback to refine QA systems, train staff, and upgrade processes. Gartner research indicates that companies using audit-driven QA improvements improve customer satisfaction scores by 17% year-on-year (Gartner, 2022).

QA provides the framework, and in-process audits enforce and refine it. Together, they create a cycle of standard-setting, verification, and continuous improvement that strengthens product quality, compliance, and customer trust.

What Are the Key Components of an In-Process Quality Audit?

The key components of an in-process quality audit are process criteria, measurable checkpoints, sampling plans, auditor responsibilities, audit frequency, and the use of checklists and templates. Each of these elements ensures that audits are structured, accurate, and actionable, ultimately strengthening the overall quality assurance framework.

Process Criteria

Defining process criteria establishes the standards against which production steps are evaluated. These may include regulatory requirements, internal SOPs, or customer specifications. Clear criteria help avoid ambiguity and ensure consistency. According to the International Organization for Standardization, companies with well-documented process criteria reduce audit errors by 22% (ISO, 2020).

Measurable Checkpoints

Checkpoints provide specific stages in the workflow where audits occur, such as raw material inspection, assembly, or packaging. They make the audit measurable and prevent defects from progressing further. A study in the Journal of Quality Technology found that organizations implementing measurable checkpoints reduced process variation by 18% (JQT, 2021).

Sampling Plans

Not every unit can be tested, which is why sampling plans are critical. They define how many items are checked at different stages to represent overall quality. The American Society for Testing and Materials reports that effective sampling reduces inspection costs by 27% while maintaining high defect detection rates (ASTM, 2020).

Auditor Responsibilities

Clearly assigning auditor roles and responsibilities ensures accountability. Auditors must verify compliance, document findings, and recommend corrective actions. The Institute of Internal Auditors found that teams with clearly defined auditor roles improved audit efficiency by 28% (IIA, 2021).

Audit Frequency

Frequency of audits determines how often checks occur, daily, weekly, or at specific production milestones. High-risk or high-volume operations often require more frequent audits to prevent costly defects. Research by Frost & Sullivan shows that businesses increasing audit frequency in critical processes saw defect-related losses fall by 20% (Frost & Sullivan, 2021).

Use of Checklists and Templates

Standardized checklists and templates ensure that audits are consistent across teams and locations. They minimize oversight and make findings easier to compare over time. According to a Deloitte survey, firms using structured audit checklists reported a 31% improvement in audit reliability (Deloitte, 2020).

The components of an in-process quality audit work together to create a structured and reliable approach. By defining standards, measuring outcomes, assigning roles, and using standardized tools, organizations ensure quality is consistently embedded into every stage of production.

What Types of In-Process Quality Audits Are Common?

The common types of in-process quality audits are process-based audits, product-based audits, system audits, layered process audits (LPA), and internal vs. external audits. Each serves a distinct role in ensuring that operations not only meet compliance standards but also foster continuous improvement.

Process-Based Audits

These audits focus on whether workflows follow prescribed procedures. For instance, in a manufacturing line, a process-based audit might check if machine calibration steps are followed at set intervals. According to a PwC survey (2021), 65% of companies that emphasized process audits reported fewer disruptions and improved compliance readiness, showing their role in stabilizing operations.

Product-Based Audits

Here the emphasis is on the output itself, finished goods or work-in-progress items. A simple analogy is quality-checking a batch of cookies for size, taste, and consistency before packaging. The American Society for Quality (ASQ, 2020) reported that firms using structured product audits reduced customer complaints by 23%, highlighting how product-specific inspections directly safeguard consumer satisfaction.

System Audits

System audits examine the overall quality management framework, ensuring that policies, controls, and objectives align with industry standards such as ISO 9001. This is akin to reviewing a household’s budgeting system rather than a single purchase. A study by ISO (2022) found that organizations with robust system audit programs experienced 20% fewer regulatory nonconformities, underlining their importance for long-term compliance.

Layered Process Audits (LPA)

LPAs involve multiple levels of staff, from supervisors to executives, regularly auditing the same processes to maintain accountability. This layered approach ensures both frontline and leadership perspectives are considered. Research by AIAG (Automotive Industry Action Group, 2021) shows that companies implementing LPAs reduced recurring quality issues by 54%, proving that shared responsibility boosts audit effectiveness.

Internal vs. External Audits

Internal audits are performed by in-house teams, focusing on self-assessment and process improvement, while external audits are conducted by third-party agencies to ensure neutrality and certification readiness. For example, an internal check might verify daily compliance logs, whereas an external auditor reviews documentation for ISO certification. According to KPMG (2021), 72% of firms that balanced both internal and external audits improved stakeholder confidence, making the dual approach essential for credibility.

These audit types ensure quality is monitored from multiple dimensions, including process, product, system, responsibility, and perspective. By adopting a mix of them, organizations not only reduce risks but also build trust with customers, regulators, and employees.

How Do You Conduct an In-Process Quality Audit Step by Step?

You can conduct an in-process quality audit step by step, planning the audit, defining scope and objectives, training auditors, performing the audit, documenting findings, and reporting and follow-up.

Planning the Audit

Build a risk-based plan that prioritizes high-impact processes, sampling strategy, and timelines. Organizations that strengthen delivery discipline (planning, risk management, governance) cut wasted investment to 9.4% of project spend, underscoring why upfront planning pays off in execution-heavy activities like in-process audits (PMI, 2021).

Defining Scope and Objectives

Write a clear scope (process boundaries, controls to test, evidence to collect) and SMART objectives to avoid audit drift. Scope creep remains common, 34% of projects globally report it, so nailing scope early reduces rework and disputes during walkthroughs and sampling (PMI, 2021).

Training Auditors

Ensure auditors are competency-based (methods, standards, interviewing, sampling, bias control) and calibrated on checklists/tools. Learning investment also improves retention and continuity: 93% of organizations cite retention as a concern, and the #1 lever to improve it is providing learning opportunities, making ongoing auditor training a business need, not a luxury (LinkedIn Workplace Learning Report, 2023).

Performing the Audit

Execute the plan with gemba walks, digital checklists, sampling, and evidence capture; escalate potential nonconformities in real time. Data-driven execution matters: a Gartner client using audit analytics reduced audit cycle time from eight weeks to one, demonstrating the productivity gains from structured, tech-enabled fieldwork (Gartner, 2025).

Documenting Findings

Effective documentation is the backbone of a successful in-process audit. Findings should be captured in a standardized format, classifying them as major, minor, or opportunities for improvement, while linking each observation to evidence such as photos, checklists, or system logs. Using a centralized digital platform ensures traceability, easier trend analysis, and faster corrective actions. Research shows that 78% of manufacturers operate in a state of quality management disconnect, with 32% relying heavily on manual or paper-based systems, leading to errors, delays, and data loss (LNS Research via MasterControl, 2023).

Reporting and Follow-Up

Issue a concise audit report (context, findings, risk, agreed actions, owners, dates) and track CAPA to closure with aging alerts. Many firms use a 60-day CAPA closure target and flag actions aging beyond 90 days, a practical benchmark to keep improvements moving; disciplined follow-through also correlates with broad productivity gains reported by organizations improving execution (AssurX, 2022; PMI, 2021).

This six-step flow turns audits into a real-time control that catches issues before they become defects or compliance failures. Embed it in your routine, and you’ll convert audits from a checklist chore into a continuous-improvement engine that protects margin and trust.

What Tools and Techniques Are Used in In-Process Quality Auditing?

The tools and techniques that are used in in-process quality auditing include audit checklists, digital audit software, SPC tools, control charts, CAPA systems, and mobile inspection apps. Each serves a unique purpose, from structuring auditor observations to driving corrective action, helping organizations reduce risks and maintain consistent performance across operations.

Audit Checklists

Audit checklists provide a systematic guide to ensure all key aspects of a process are reviewed. For example, in a pharmaceutical plant, a checklist may include cleanliness, equipment calibration, and documentation accuracy. Research by the Chartered Quality Institute (2021) found that organizations using structured checklists improved audit completeness by 32%, reducing the likelihood of oversight.

Digital Audit Software

Digital platforms replace paper-based systems by enabling real-time data capture, auto-generated reports, and analytics dashboards. This allows faster communication of findings and seamless integration with compliance frameworks. According to PwC (2022), companies implementing digital audit solutions saw compliance reporting efficiency improve by 38%, reflecting how technology shortens audit cycles.

SPC Tools (Statistical Process Control)

SPC tools apply statistical methods to measure and monitor process stability. They are often used to check whether variations remain within acceptable limits. A study published in Quality Engineering (2021) revealed that companies using SPC achieved a 15–20% improvement in production consistency, preventing costly rework and downtime.

Control Charts

Control charts visualize performance trends over time, helping auditors detect abnormalities before they escalate. For instance, plotting defect rates across shifts highlights process variations linked to operator or machine changes. Research by IEEE (2020) reported that control chart adoption led to a 22% drop in defect recurrence, showing their value in continuous monitoring.

CAPA Systems (Corrective and Preventive Action)

CAPA systems provide a closed-loop framework for investigating nonconformities, identifying root causes, and ensuring recurrence is prevented. By formalizing accountability and timelines, they strengthen follow-through. According to LNS Research (2021), firms with robust CAPA systems resolved issues 50% faster than those using ad hoc approaches.

Mobile Inspection Apps

Mobile apps enable field teams to record evidence instantly through photos, videos, and geotagging, syncing data directly to central quality systems. This makes audits more agile across multiple sites. A study by TechValidate (2022) found that organizations using mobile-enabled audits reported a 25% improvement in audit accuracy, as findings were captured in real time rather than after the fact.

By integrating these tools and techniques, organizations create a layered quality ecosystem that balances efficiency, compliance, and risk reduction. When used together, they transform audits from a reactive task into a proactive quality assurance engine.

What Standards Govern In-Process Quality Audits?

The standards that govern in-process quality audits are ISO 9001, ISO 19011, IATF 16949, GMP, AS9100, and other industry-specific frameworks. These standards establish the rules of the game, defining how audits should be planned, executed, and followed up, so that organizations can maintain credibility, compliance, and customer trust.

ISO 9001: Quality Management Systems

ISO 9001 is the most widely adopted global quality management standard, requiring organizations to conduct in-process audits that verify whether processes consistently deliver desired results. As of 2022, more than 1.2 million certifications were issued worldwide, reflecting its influence across industries (ISO, 2022).

ISO 19011: Guidelines for Auditing

ISO 19011 provides universal guidelines for auditing management systems, covering principles like impartiality, competence, and evidence-based reporting. It ensures that in-process audits are carried out systematically and consistently across sectors.

IATF 16949: Automotive Quality Management

In the automotive sector, IATF 16949 governs in-process audits with a focus on defect prevention and efficiency. It mandates Layered Process Audits (LPA) where multiple organizational levels verify compliance. With over 78,000 global certificates (IATF, 2021), it is the cornerstone of automotive quality control.

GMP (Good Manufacturing Practices)

In pharmaceuticals, food, and cosmetics, GMP standards regulate in-process checks to ensure product safety and uniformity. For example, drug manufacturing requires blend uniformity tests as part of GMP. A WHO report (2021) highlighted that non-compliance with GMP remains a leading cause of product recalls, making these audits critical for public safety.

AS9100: Aerospace Quality Standard

AS9100 extends ISO 9001 principles with stricter requirements for traceability, risk management, and safety-critical audits in aerospace. According to IAQG (2021), certified organizations reported fewer supply chain disruptions, thanks to rigorous in-process quality checks.

Other Industry-Specific Standards

• FSSC 22000 & ISO 22000: Food safety and in-process monitoring of critical control points.
• IEC/ISO 17025: Laboratory testing and in-process validation of methods.
• API Q1/Q2: Oil and gas operations with focus on process safety and reliability.

These standards ensure that in-process quality audits are structured, consistent, and globally recognized. By aligning with them, organizations move beyond basic compliance toward continuous improvement and stakeholder confidence.

How Do You Handle Non-Conformities Found During In-Process Audits?

You can handle non-conformities found during in-process quality audits by classification of non-conformances, root cause analysis, corrective and preventive actions (CAPA), and documentation and escalation procedures. Each step ensures that deviations are not only addressed but also prevented from recurring, turning issues into opportunities for systemic improvement.

Classification of Non-Conformances

The first step is to categorize non-conformities into major, minor, or observations. For example, a missing safety guard on equipment would be a major non-conformance, while a small labeling error might be minor. A BSI Group survey (2022) found that organizations using structured classification frameworks resolved quality issues 27% faster, since prioritization helped allocate resources effectively.

Root Cause Analysis

Once identified, non-conformities must be analyzed to uncover their true cause, not just the symptom. Methods like the “5 Whys” or Fishbone Diagram help break down complex issues. According to a study in the Journal of Manufacturing Technology Management (2020), companies applying systematic root cause analysis reduced repeat non-conformities by 31%, proving its role in sustainable quality improvement.

Corrective and Preventive Actions (CAPA)

CAPA involves creating a closed-loop system to correct immediate issues (corrective action) and implement safeguards to avoid recurrence (preventive action). This strengthens compliance and accountability. Research by Sparta Systems (2021) reported that firms with robust CAPA programs saw a 35% reduction in audit findings over three years, highlighting their long-term impact.

Documentation and Escalation Procedures

All non-conformities and resolutions must be documented in detail and escalated when they exceed defined risk thresholds. This ensures traceability and management visibility. A Compliance Week survey (2022) showed that companies with formal escalation policies achieved 40% quicker closure of critical non-conformances, as leadership involvement accelerated decision-making.

Handling non-conformities effectively is not just about fixing problems but about building a culture of learning and accountability. By embedding these four practices, organizations ensure that every audit becomes a driver of continuous improvement and resilience.

What Is the Role of In-Process Audits in Risk Management?

The role of in-process quality audits in risk management includes risk-based audit scheduling, identifying high-risk processes, mitigating potential failures early, and linking to FMEA (Failure Mode and Effects Analysis).

Risk-Based Audit Scheduling

In-process audits help organizations prioritize audit frequency based on risk exposure, rather than using a fixed calendar. For instance, processes involving hazardous materials or customer safety get scheduled more often than low-impact administrative tasks. According to Deloitte (2021), risk-based internal audit programs reduced compliance breaches by 28%, showing how targeted scheduling reduces exposure.

Identifying High-Risk Processes

Audits act as a lens to pinpoint operations most likely to cause disruption, non-compliance, or customer dissatisfaction. A practical example would be identifying bottlenecks in a supply chain that carry both quality and delivery risks. The Institute of Internal Auditors (2022) reported that organizations using risk-focused audits improved early detection of operational risks by 33%, strengthening overall governance.

Mitigating Potential Failures Early

By detecting deviations during production, in-process audits help correct issues before they escalate into costly failures or recalls. This is especially critical in industries like healthcare and aerospace, where small errors have outsized consequences. A McKinsey study (2020) showed that catching defects mid-process costs up to 10x less than addressing them after final delivery, proving the economic case for early mitigation.

Linking to FMEA (Failure Mode and Effects Analysis)

In-process audits also complement FMEA, a structured method for analyzing potential failure points and their impact. Audit findings feed into FMEA, which then guides preventive strategies. Research in the International Journal of Quality & Reliability Management (2021) found that companies integrating audits with FMEA reduced failure occurrence by 29%, creating a closed loop between detection and prevention.

In-process quality audits serve as a frontline defense in risk management. By combining proactive scheduling, high-risk targeting, early mitigation, and FMEA integration, organizations build a system that not only prevents failures but also drives long-term resilience.

What Are the Best Practices for Implementing In-Process Audits?

The best practices for implementing in-process audits are cross-functional collaboration, auditor training and calibration, rotational audits, clear metrics and KPIs, and leadership buy-in.

Cross-Functional Collaboration

Engaging multiple departments, production, quality, maintenance, and even supply chain, brings diverse perspectives to audits. This ensures that risks are viewed holistically rather than in silos. A Harvard Business Review study (2021) showed that organizations with strong cross-functional collaboration were 31% more effective at solving complex operational problems, making teamwork a key enabler for robust audits.

Auditor Training and Calibration

Auditors need not only technical knowledge but also skills in interviewing, observation, and objective reporting. Calibration sessions, where auditors review the same process and compare results, reduce subjectivity. According to the Institute of Internal Auditors (2022), companies that invested in structured auditor training achieved 27% higher accuracy in audit findings, strengthening trust in the process.

Rotational Audits

Rotating auditors across departments prevents bias and introduces fresh perspectives. It also reduces the risk of complacency, where teams get too familiar with processes. Research published in The TQM Journal (2020) found that rotational audits cut repeat non-conformities by 22%, as auditors were more likely to spot overlooked issues.

Clear Metrics and KPIs

Defining measurable indicators, such as defect rates, audit closure timelines, or the number of repeat issues, helps track audit effectiveness. Without KPIs, audits risk becoming paperwork rather than performance tools. A PwC report (2021) highlighted that organizations with defined quality KPIs improved audit-driven process improvements by 35%, showing the importance of metrics-driven monitoring.

Leadership Buy-In

Management commitment sets the tone for audit success. Leadership ensures that audit findings are acted upon and not ignored. A Gallup workplace survey (2022) reported that teams with strong leadership engagement were 3.9x more likely to resolve operational issues quickly, proving that top-level support transforms audits into actionable outcomes.

By embedding collaboration, training, objectivity, metrics, and leadership support, organizations can turn audits into a cornerstone of quality and risk management.

How Are In-Process Quality Audits Documented and Reported?

The in-process audits are documented and reported using templates and documentation standards, audit trail best practices, and integration with QMS software. Proper documentation ensures transparency, traceability, and actionable insights, while structured reporting enables timely corrective actions and continuous improvement.

Templates and Documentation Standards

Standardized templates help auditors capture findings consistently, covering areas such as process compliance, deviations, risk rating, and corrective actions. Templates reduce ambiguity and ensure that all critical aspects are recorded uniformly. According to a study by the Chartered Quality Institute (2022), organizations that implemented structured audit templates experienced a 28% faster audit closure rate, as findings were easier to interpret and act upon.

Audit Trail Best Practices

Maintaining a complete audit trail is crucial for verifying the sequence of audit activities and decisions. This includes documenting evidence, timestamps, reviewer approvals, and follow-up actions. The importance of audit trails is underscored by a Thomson Reuters report (2022), which found that 74% of compliance failures were linked to incomplete or inconsistent audit records, highlighting that proper tracking prevents regulatory and operational gaps.

Integration with QMS Software

Integrating audits into Quality Management System (QMS) software allows real-time tracking of findings, automated reminders for corrective actions, and dashboards for management review. This reduces manual errors and improves the speed of follow-up. Gartner (2021) reported that companies using QMS-integrated audit tools achieved a 40% faster response to non-conformities, demonstrating efficiency gains and better alignment with organizational quality objectives.

Documenting and reporting in-process audits systematically ensures that findings are actionable, traceable, and aligned with organizational quality goals. By combining standardized templates, robust audit trails, and QMS integration, organizations turn audits into a continuous improvement tool rather than a one-off compliance exercise.

How Often Should In-Process Quality Audits Be Performed?

The in-process audits should be performed by determining frequency based on risk, volume, and history, following industry benchmarks, and using tiered audit scheduling. Establishing the right frequency ensures that audits are effective, resource-efficient, and targeted to areas of greatest impact.

Determining Frequency Based on Risk, Volume, and History

Audit frequency should be aligned with the risk level of the process, production volume, and past performance. High-risk processes or high-volume operations typically require more frequent audits, while stable, low-risk areas may be audited less often. A PwC report (2021) found that risk-based audit planning reduced process deviations by 26%, emphasizing the importance of focusing resources where they matter most.

Industry Benchmarks

Many sectors have recommended audit intervals based on regulatory or quality standards. For example, pharmaceutical GMP guidelines suggest monthly or quarterly audits for critical processes, while ISO 9001 recommends periodic audits aligned with process complexity. According to a BSI survey (2022), organizations that benchmarked their audit frequency against industry norms achieved a 22% higher rate of early issue detection compared to companies using arbitrary schedules.

Tiered Audit Scheduling

Tiered or layered audit scheduling involves multiple levels of audits, such as operator-level checks, supervisor audits, and management reviews. This approach ensures both depth and breadth of oversight. Research published in The TQM Journal (2020) indicated that tiered audit systems reduced repeat non-conformities by 30%, as issues were caught at multiple points before escalating.

Determining the optimal frequency for in-process audits requires balancing risk, regulatory expectations, and operational realities. By combining risk-based planning, industry benchmarks, and tiered scheduling, organizations ensure audits remain proactive, focused, and effective.

What Are The 4 Types Of Quality Audits?

The four types of quality audits are internal audits, external audits, process audits, and product audits. Each type serves a specific purpose in ensuring that an organization’s quality management system is effective, compliant, and continuously improving.

1. Internal Audits

Internal audits, also called first-party audits, are conducted by an organization’s own staff to evaluate compliance with internal procedures, standards, and policies. They help identify gaps, improve processes, and prepare for external audits. According to the Institute of Internal Auditors (2022), organizations conducting regular internal audits experience a 20–30% reduction in non-conformities compared to those relying solely on external assessments.

2. External Audits

External audits, or second- and third-party audits, are performed by customers, regulatory bodies, or independent certification organizations. They verify compliance with contractual, legal, or standard requirements and provide credibility to stakeholders. ISO 9001-certified companies often undergo annual external audits to maintain certification and demonstrate conformity.

3. Process Audits

Process audits focus specifically on how processes are performed rather than the end product. They examine workflows, controls, documentation, and operational efficiency to ensure that processes produce consistent and compliant outcomes. A study in Quality Management Journal (2021) found that process audits can reduce operational errors by 15–25% when conducted systematically.

4. Product Audits

Product audits, or third-party inspections, evaluate the final product or intermediate outputs against defined quality specifications. They are crucial in industries like manufacturing, pharmaceuticals, and electronics to verify that the product meets customer requirements and regulatory standards. According to ASQ (2021), organizations performing periodic product audits detected up to 18% more defects early in the production cycle compared to relying on final inspection alone.

The four types of quality audits—internal, external, process, and product—complement each other to ensure comprehensive quality management. Together, they help organizations maintain compliance, improve processes, and reduce defects systematically.

Who Performs In-Process Quality Audits?

In-process quality audits are typically performed by trained auditors who can be internal staff, external experts, or cross-functional teams depending on the organization and the purpose of the audit. The goal is to ensure objectivity, compliance, and effective identification of process gaps before they impact the final product.

1. Internal Auditors

Internal auditors are employees of the organization who are trained in audit techniques and quality standards. They are often part of the quality assurance (QA) or quality control (QC) department but may also include personnel from other departments to bring diverse perspectives. According to the Institute of Internal Auditors (2022), organizations with dedicated internal auditors detected 20–30% more process deviations compared to ad hoc inspections.

2. Cross-Functional Teams

Many organizations use cross-functional audit teams comprising members from production, maintenance, supply chain, and QA/QC. This approach ensures a holistic view of the process, encourages knowledge sharing, and reduces blind spots. A study in The TQM Journal (2021) showed that cross-functional audits increased identification of process inefficiencies by 25%.

3. External Auditors

External auditors, such as certification bodies or regulatory inspectors, may also perform in-process audits to verify compliance with ISO standards, GMP, or customer-specific requirements. Their involvement adds an additional layer of objectivity and credibility. According to ISO (2022), companies engaging external auditors for periodic in-process checks reported a 15% improvement in audit closure rates, reflecting enhanced accountability.

4. Rotational Auditors

Some organizations implement rotational audits, where auditors rotate across departments or production lines. This ensures fresh perspectives, reduces bias, and helps catch issues that familiar auditors might overlook. Research by BSI Group (2021) found that rotational auditing reduced repeat non-conformities by 20%.

In-process quality audits are performed by internal auditors, cross-functional teams, external experts, or rotational auditors, depending on the organizational setup and audit objectives. Selecting the right auditors ensures that the audits are objective, comprehensive, and effective in driving continuous improvement.
