Plan, Do, Check Act (PDCA)


What is Plan, Do, Check Act (PDCA)?

If you are a part of an Environmental, Health, and Safety (EHS) team or a manager in your organization responsible for implementing EHS management systems, you may have come across the term “PDCA.” 

The Plan, Do, Check, Act (PDCA) cycle is a fundamental framework widely used in the realm of EHS management. It is a systematic approach that focuses on continuous improvement, ensuring the efficiency and effectiveness of your organization’s processes.

Understanding the Plan, Do, Check Act (PDCA)

The PDCA cycle, also known as the Deming Cycle or Shewhart Cycle, is a four-step process that provides organizations with a systematic method for managing and continually improving processes. The cycle consists of the following steps: 


The first step in the PDCA cycle is “Plan.” In this stage, organizations identify their EHS objectives and develop strategies and plans to achieve them. 

This involves conducting a comprehensive review of existing processes, analyzing potential risks, and setting appropriate key performance indicators (KPIs). 

The goals and objectives must be specific, measurable, achievable, relevant, and time-bound (SMART) to ensure clear expectations and effective tracking of progress.


The second step in the PDCA cycle is “Do.” In this phase, organizations execute their plans and carry out the proposed activities. 

This can include implementing new procedures, controls, or equipment to improve EHS performance, as well as training staff on any changes or updates. 

During the "Do" phase, it is crucial to maintain thorough documentation and collect data on the effectiveness of the executed plans. 

This data will play a pivotal role when it comes to evaluating the fruits of your labor in the following "Check" stage.


The third step is the “Check” phase, in which organizations assess their EHS performance by comparing the collected data against the pre-defined KPIs and objectives. 

The results obtained from this analysis will highlight whether the implemented actions were successful or not. 

Organizations should also identify any deviations from the anticipated results and any areas requiring improvement. 

If the objectives have not been met, organizations need to determine the root cause of the problem and consider potential solutions moving forward.


During the final “Act” phase, appropriate corrective actions are taken based on the outcomes of the “Check” phase. 

This involves making necessary adjustments to ensure the initial objectives and KPIs are met. Once the optimal results have been obtained and solutions are proven to be effective, organizations should standardize the improvements to prevent regression and potential future problems. 

After the solutions are implemented and standardized, the PDCA cycle can be reinitiated to continuously improve other areas of EHS management.

One of the main benefits of the PDCA cycle is that it fosters an environment of continuous improvement. 

By regularly reviewing processes and making adjustments, the organization can ensure they are always moving forward and making strides to enhance performance. 

Moreover, PDCA allows for flexibility in tackling issues, engaging all members of the organization in the improvement effort.

How Can PDCA be Applied to EHS Processes?

Some specific ways PDCA can be applied to EHS processes include:

Hazard identification and risk assessment

The PDCA cycle can be used to perform a thorough hazard analysis and create effective control measures, continuously updating the evaluation, and improvement process.

Incident management 

PDCA can guide the investigation process to identify the root cause of incidents, develop corrective actions, and evaluate the effectiveness of those actions, ultimately preventing recurrence.

Training and competence 

The cycle can be used to plan, develop, and evaluate training programs to ensure employees are effectively equipped with the knowledge and skills to perform their tasks safely.

Emergency preparedness and response 

Organizations can apply PDCA to develop, implement, test, and improve emergency response plans to keep their workforce and the environment safe in critical situations.

Compliance management 

PDCA can be employed to manage legal and other requirements related to EHS, ensuring that the organization's policies, procedures, and practices align with the latest regulations and industry standards.
