What is the PDCA Model?

The PDCA Model is a Problem-Solving tool that suggests 4 simple Steps to achieve Goals efficiently.

  • Its Name is an acronym for the Steps suggested: Plan, Do, Check, Act.


These steps can (or should) be repeated cyclically in order to improve the results obtained.


As in many other Continuous-Improvement tools, the more you repeat the cycle, the closer you will be to finding the solution or reaching the end goal.

Four Steps of the PDCA Model

1. Plan: In this first Step, you should:

  • Define the Problem or the Goal you want to achieve.
  • Design a Strategy or a Method to do it.


2. DoIn this Step, you should:

  • Implement the necessary actions to comply with the Plan.


3: Check: In this Step, you should:

  • Check the results obtained.
  • Choose and Use the right metrics.
  • Find out what worked and what didn’t.


4: Act: In this Step, you should:

  • Adopt the modifications that have proven to work.
  • Come up with a new Plan to fix what isn’t working yet.


This cycle is meant to be repeated frequently:

  • If you have not been able to reach your initial Goal, you must repeat it until you have achieved it.
  • If you have reached your initial Goal, you should look for the Next one.


Let’s see the first example so that you understand it better:

PDCA Model example


Imagine that you own a Restaurant specialized in ribs.

  • You are doing relatively well but recently, your ribs are not as appreciated as in the past.
    • You think people are a little “tired” of your recipe.


You want to discover a new recipe that will drive your customers crazy.


Since you are not a very methodical person, you decide to use the PDCA Model:




Your Goal is to find a new successful Recipe for your Ribs.

To do so:

  • You’ll start offering 5 alternatives to your Clients.
  • Every week, you will keep the top 3 and introduce 2 new ones.

You’ll use an iterative process to find which ingredients and cooking processes your customers like best.




The first week, you prepare the 5 best recipes you know, listing all the ingredients that each one has and what cooking processes you followed.

  • Once you have feedback, you’ll make different modifications.




At the end of every week, you check the most successful recipes.

  • The ingredients they have (spices, amount of salt, rib supplier, etc).
  • The cooking process used (which charcoal yo used, how much time you employed, etc).

Your goal in this step is to see if your recipes are going in the right direction.




Once you have checked the best recipes, you analyze and decide what new recipes you will use next week.
