What Works Better for Project Improvement

Statistics suggest that about 70% of the projects failed, despite the high technical quality and the high level of dedication from the team members. There are many factors that come into play but if you look at the root cause, it’s usually an issue with project management or the methodology which was used to tackle the project in the first place. This article will show you different project management methods and their uses. Let’s discuss some of them.

Organizational improvement is largely driven by either DMAIC vs PDCA models. In this article, our 3D rendering company explores how each strategy works, differs from the other and makes them effective at improving project results.

Let’s dive into it!

#1. PDCA vs DMAIC – Brief Intro & Overview

The PDCA cycle is a process for managing projects created by Fred Brooks in the early 1970s. Brooks knew that improvement was difficult and time-consuming. He developed a model to help project teams improve their processes. 

DMAIC is an approach to improving projects used by Toyota in the 1980s. Toyota realized that effective management of projects required clarity about objectives. Execution of measures to achieve objectives and monitoring of results.

Both PDCA and DMAIC are important tools for improving the quality of projects. They work throughout the improvement cycle and share common goals. 

#2. What is PDCA?

What is PDCA

PDCA is a tool used in business improvement and quality management. The Plan-Do-Check-Act (PDCA) is a continuous improvement cycle. It’s also known as the Deming Cycle after its inventor W. Edwards Deming. 

This process emphasizes continuous improvement over time. Each phase builds on previous ones to ensure that they are making progress toward goals. This final step involves taking action based on what has been learned during the check stage. This can include changing anything that was done, or implementing new measures if required. 

PDCA comprises 4 distinct steps:


This step involves creating a plan to solve the problem by setting goals and objectives. It is important to determine who will solve the problem, as well as what resources will be required for this.


This step includes implementing the plan and doing whatever is necessary to make it work.


This step is all about monitoring the progress made and making any necessary adjustments. It helps to ensure that the goals of the plan are being met and all problems have been fixed. 


In this final step, action is taken based on what has been learned during the check stage. This can mean changing anything that was done, or implementing new measures if required.

The benefits of using PDCA include: 

  • Identifying problems within an organization so that they can be fixed.
  • Creating a culture of continuous improvement within the company. 
  • Improving quality, efficiency, and productivity.
  • Boosting customer satisfaction by providing better products and services.
  • Reducing project costs.

#3. What is DMAIC?

Quality improvement is a continuous process. During the course of a project, there will be many instances when quality improvement can occur. The most common method of quality improvement is Six Sigma. Six Sigma is a quality management system that uses statistical methods to reduce variation in products and services. This helps companies meet customer requirements regarding product quality, service levels, cost, and time.

One of the most important aspects of Six Sigma is DMAIC (Define, Measure, Analyze, Improve and Control). This method is used to improve processes by identifying the root cause of problems and then implementing changes to eliminate them.

DMAIC is a more holistic approach to problem-solving, which emphasizes the need for collaboration and communication throughout the process. DMAIC incorporates steps from PDCA into its overall framework but also includes other methods such as brainstorming and team building.

The DMAIC framework is a method for enhancing project effectiveness, identifying opportunities for improvement, analyzing root causes, developing and implementing solutions, and measuring the overall performance. 

DMAIC is focused on creating something new or fixing existing problems using a structured approach with 5 phases:


The first step is to determine what needs to be achieved or improved. This may include setting goals or targets, as well as identifying indicators to measure progress towards those.


The second step in DMAIC is to measure current performance against set goals or targets. This step usually involves collecting data from multiple sources to have a complete picture of the current situation before moving on to any changes or improvements.


The third step is to analyze the data collected in the second step to determine the root causes of any problems.


After analyzing the data, it’s time to come up with ideas for improving the project and bringing it to life. This stage also incorporates brainstorming and testing even the most creative ideas.


Once new ideas have been tested and implemented, you need to track their effectiveness over time. For that, one can use metrics such as Pareto charts and control charts so that any issues can be caught early before they become major problems.

The benefits of using DMAIC include: 

  • Improved project effectiveness: DMAIC helps ensure that projects are implemented, reducing the time and cost associated with fixing problems after a project is completed.
  • Better decision making: The ability to identify and correct problems early in a process allows for better decisions regarding what actions need to be taken, leading to more efficient use of resources and faster completion of projects.
  • Reduced cycle time: By eliminating the need for retrospective analysis, DMAIC can reduce cycle times by up to 50%. This means that products or services can reach the market sooner, resulting in increased profits for the company.
  • Increased customer satisfaction: By properly addressing issues early on in the process, customers are more likely to be satisfied with the final product or service.
  • Reduced waste: DMAIC helps to identify and correct problems before they cause any significant damage or loss, leading to reduced waste and improved efficiency of resources. 

#4. PDCA vs DMAIC: Common and Different 

To make the best choice for your project improvement, you need to know how PDCA and DMAIC differ from each other and how to implement them in the best way. 

PDCA and DMAIC aim to improve processes within organizations but each has its own unique way of doing this. The main difference between PDCA vs DMAIC lies in their focus on different aspects of process improvement.

PDCA is focused on measuring performance to identify problems and take corrective action. DMAIC’s main goal is measuring performance as well as analyzing data from various sources to find the root causes of problems to prevent them or fix them effectively.

The focus of PDCA is on the overall process while DMAIC is aimed at each step of improvement separately. PDCA is more comprehensive in its approach, providing a better framework for project success. DMAIC helps improve performance by focusing on specific areas, such as making sure actions are being taken and monitoring results.

There is no one right answer when it comes to choosing between PDCA vs DMAIC. The best approach depends on a specific project, its goals, and its features. If you are unsure which strategy would work best, talk to an expert or consult a resource like PMP Training Reviews.

While both PDCA and DMAIC are used to improve processes, products, and services they are not interchangeable. They can be used in Six Sigma, Lean, and other improvement processes and quality management. Both tools provide a simple way of managing project improvements over time while using data collection methods to track the success of each action plan item or objective.

As a continuous improvement process, PDCA is a good fit for companies that are already doing well and want to keep their processes running. It’s also useful when trying to improve a product or service because it focuses on identifying problems as well as creating solutions for them.

    Very good analysis of Project management improvements, tools n processes developed to carry out. Correction within on going processes, to eliminate the waste and improve the Quality and get customers satisfaction, both PDCA n DMAIC forms a basis of improvement as per the project types undertaken.
