What is a Layered Process Audit? Defining LPAs

Auditing processes in the manufacturing, distribution, and healthcare sectors is not merely a luxury; it’s the cornerstone of any organization striving for excellence in its products and services. Maintaining high-quality, safe, and efficient procedures cannot be overstated since the repercussions of subpar standards can be damaging, leading to lost customers, rework, product recalls, and reputational damage.

What Are Layered Process Audits (LPAs)? Defining LPAs

Layered Process Audits (LPA) are structured audits conducted across multiple organizational layers or levels to ensure process compliance. LPAs involve frontline employees, middle management, and upper management. Auditors follow an audit checklist and verify different workplace areas, processes, or assessment criteria depending on their level of authority.

LPAs are a robust quality, safety, and efficiency technique that shifts the focus from inspecting finished products and services to validating the processes that produce them. At their core, LPAs are a proactive approach to management. The primary objective is consistently following operational procedures, maintaining quality standards, rectifying deviations at the earliest possible stage, and driving continuous improvement.

Audit Layers – Involving Multiple Levels of Auditors

At the heart of Layered Process Audits are multiple layers within an organization. These layers involve individuals from various management tiers, each with a distinct focus and scope of assessment:

Layer 1 – Frontline Employees and Operators:

Frontline employees conduct audits within their workstations or areas. Their audits concentrate on adhering to safety standards and standard operating procedures (SOPs). These employees are well-positioned to identify issues as they are directly engaged in day-to-day operations.

Layer 2 – Team Leaders and Supervisors:

Team leaders or supervisors play a pivotal role in conducting audits. These audits mainly verify that team members follow established procedures and safety protocols.

Layer 3 – Managers and Directors:

Middle managers (production managers or department heads) participate in LPAs to assess overall performance. They review processes, resource allocation, and efficiency, often identifying training needs, resource requirements, or improvement opportunities.

Layer 4 – C-Level Executives:

Senior management (top executives) engage in LPAs to gain a high-level view of the organization’s processes. Their audits focus on strategic aspects, such as alignment with organizational goals and regulatory compliance. Senior management’s involvement underscores its commitment to quality and continuous improvement.

Cross-functional Teams:

LPAs may also involve cross-functional teams collaborating to address non-conformity identified during audits. These teams guarantee a comprehensive strategy for overseeing quality, safety, and efficiency control.

Quality Assurance and Continuous Improvement Teams:

Quality assurance and continuous improvement teams are the driving force behind LPA programs. They coordinate the audit schedule, provide training, and promptly take corrective actions. These groups play a crucial role in fostering a culture of accountability.

The overarching principle in conducting LPAs is collaboration among all management levels, relentlessly focusing on transparency, accountability, and continuous improvement.

LPAs involve multiple layers of auditors across the organization, each with a different scope.

LPA Frequencies – Scheduling Layered Process Audits

The frequency of Layered Process Audits varies depending on the level conducting the audit: the closer an auditor is to the audited area, the more frequently they will complete the audit. For instance, a line supervisor may perform daily audits, while a plant manager might conduct monthly audits.

Moreover, LPA schedules are an essential tool when implementing Leader Standard Work. Set the LPA schedule for regular assessments and choose from daily, weekly, monthly, or custom recurrence to ensure auditors stay on top of their deadlines.

Schedule Layered Process Audits in your auditors' calendars to ensure timely assessments.

How to Conduct Layered Process Audits (LPAs)

Layered Process Audits are structured processes involving several vital steps. Here’s a roadmap for conducting effective LPAs:

  1. Define Critical Processes:

    Begin by clearly outlining the processes that require auditing. These could include safety protocols, quality control procedures, and more.

  2. Create Audit Checklists:

    Develop detailed checklists or assessment criteria to comprehensively cover each step of the audited processes. These checklists serve as a guide for auditors to evaluate compliance.

  3. Assign Auditors:

    Assign individuals from each management level to conduct audits. For example, team leaders could audit frontline operators. Managers could audit team leaders, et cetera.

  4. Schedule Auditing Frequency:

    Set daily, weekly, monthly, or custom audit frequencies in auditors’ calendars to increase ownership and adherence to best practices.

  5. Conduct Audits:

    Regularly conduct audits using checklists. Auditors verify the processes and identify any non-compliance.

  6. Document Findings:

    Audit findings, both positive observations and areas requiring improvement, must always be documented and delegated to the appropriate team.

  7. Analyze Data:

    Collect and analyze audit data to discern trends, recurring issues, and potential areas for process enhancement.

  8. Manage Corrective and Preventive Actions:

    When auditors identify discrepancies or issues, they must define actions, escalate or assign them to the right management layers, and involve cross-functional teams.

  9. Feedback Loop:

    Share audit results and improvement actions with relevant stakeholders. Transparency is critical to building awareness and accountability.

In brief, establishing clear roles and responsibilities for each layer is necessary to ensure that findings from LPAs are not just isolated observations but catalysts for meaningful progress.

Why Conduct Layered Process Audits? Importance and Benefits

Layered Process Audits hold significance in process improvement, quality, and safety control. Here’s why they are indispensable:

Above all, the benefits of LPAs extend beyond tangible improvements to include intangible gains, such as increased floor time for management, reinforced process steps, and the demonstration of the importance of critical processes to the entire organization.

The Advantages of Digitized Layered Process Audits

The transition from traditional paper-based audits to digital Layered Process Audits offers countless advantages:

Digital LPAs also improve visibility into document modifications, prevent manual errors, and facilitate continuous improvement initiatives. With digital platforms, users can assign audits efficiently, ensuring that the right individuals receive the correct requests at the right time.
