Use Case

Layered Process Auditing (LPA)

What is a Layered Process Auditing (LPA) Audit process?

LPA (Layered process audit) are processes that aim to increase the quality of finished products, by auditing the production process and inspecting how products are made, instead of just observing the finished version.

This process aims at conducting regular internal audits, in every hierarquical level. The in-depth analysis is part of a Quality Management System that helps the organization to detect gaps and areas of improvement in the company.

How is a Layered Process Auditing (LPA) Audit process implemented?

With LPAs, every layer of management participates in daily checks of high-risk processes, which requires a solid plan and a prepared team. Every layer uses PDCA processes to audit their attributed area.

With a continuous improvement focus, the LPA Audit will make it possible to correct existing mistakes quickly and then, use the information to optimize all processes that were audited.

The process is divided into 4 major steps:

  1. Walkthrough the factory to observe activities, processes, and products.

  2. Secondly, all processes associated documents are reviewed to ensure if the followed processes are in conformity.

  3. Finally, a GMP audit checklist is prepared for specific verifications of both of the above activities.

  4. Results are analyzed.

The process requires steps that take into consideration 5 fundamentals: Risk Management, Quality Management Systems, Facilities Management, Product Contol, and, finally, Continuous Improvement of all actions.

How Industry 4.0 can influence the process?

STEP 1: Process Digitalization

Digital platforms allow to centralize data and create digital checklists to support the process. They are available for different management layers, providing field workers with information to execute their process and give feedback. It provides management teams with analytics about execution facilitating the detection of potential improvements.

STEP 2: Output analytics

Automatic reports and dashboards are generated according to execution. Data is displayed in a visual way that facilitate both comprehension and analysis. It becomes easier to understand where and why problems happen and take corrective measures.


Increased visibility
Increased control
Guaranteed execution
Process digitalization efficiently combined with IoT increases visibility and control over any process. It allows to easily visualize through a see-through screen, information and guides about process, and, data from equioment behaviour, superimposed in the real industrial environment. Additionally, by collecting visual evidence of the executed tasks, it is possible to confirm the correct execution, reducing the possibility of unexpected errors.

How can we help?

A unique platform that combines process digitalization with IoT data extracted from the factory floor. The platform organizes workflows according to different needs and users. Not only the platform deploys valuable inputs but also generates automatic reports that gather the different hierarchical levels observations and notes. This facilitates decision-making but also allows it to be more concise
