INFORMATION SHEET 2.1
The PDCA cycle
USE
The PDCA cycle is designed to be used as a dynamic model. The
completion of one turn of the cycle flows from the beginning of the next.
Following in the spirit of continuous quality improvement, the process can
be realized and a new test of change can begin. This continual cycle of
change is represented by the ramp of improvement. Using what you learn in
one PDCA, you can begin another more complex trial.
Plan. It is a change or a test, aimed at improvement.
In this phase, analyze what you intend to improve, looking for
areas that hold opportunities for change. The first step is to choose
areas that offer the most return for the effort you put in-the biggest bang
for your buck.
Do. It is to carry out the change or test (preferably on a small scale).
Implement the change you decided on in the plan phase.
Check or Study the results. The basic questions are: What was
learned? What went wrong?
This is a crucial step in the PDCA cycle. After you have
implemented the change for a short time, you must determine how
well it is working. Is it really leading to improvement in the way you
had hoped? You must decide on several measures with which you
can monitor the level of improvement. Run Charts can be helpful
with this measuring instruments.
15
Act. It is to adopt the change, abandon it, or run through the cycle again.
After planning a change, implementing and then monitoring it, you
must decide whether it is worth continuing that particular change.
If it consumed too much of your time, was difficult to adhere to, or
even led to no improvement, you may consider aborting the change
and planning a new one. However, if the change ads to a desirable
improvement or outcome, you may consider expanding the trial to
a different area, or slightly increasing your complexity. This sends
you back into the Plan phase and can be the beginning of the ramp
of improvement.
Example 1: The Student with Poor Grades in NCII Examination
Robert is a graduate student in a vocational high school who has just taken
his first set of examinations and is very unhappy with the results.
 What is he trying to accomplish? Robert knows that he needs to
improve his studying skills in order to gain a better understanding of
the material.
 How will he know that a change is an improvement? Robert considers
the most important measure of his study skills to be his NCII holder.
However, he does not want to risk another examination period just to
find out that his skills are still not good. He decides that a better way
to measure improvement is by taking old exams for the NCII.
 What changes can he make that will result to improvement? Robert
thinks that he has spent too little time studying. He feels that the best
way to improve his study skills is by having an ample time.
Cycle 1
Plan: Robert decides to add an additional thirty hours per week to his
already busy schedule. He resolves that he must socialize less, get up
earlier, and stay up later. At the end of the week he will take an old exam to
see how he is progressing.
Do. By the end of the week, Robert finds that he was able to add only fifteen
hours of studying. When he takes the exam he is dismayed to find that he
does no better.
Check: The fifteen extra hours of studying has made Robert feel fatigued. In
addition, he finds that his ability to concentrate during those hours is rather
limited. He has not exercised all week and has not seen any of his friends.
This forced isolation is discouraging him.
Act: Robert knows that there must be another way. He needs to design a
better, more efficient way to study that will allow his time to exercise and
socialize.
16
Cycle 2
Plan: Robert contacts all his technical/technology school friends whom he
knows are doing well yet still have time for outside lives. Many of these
friends have similar advice that Robert thinks he can use. Based on his
findings, he decides to always attend lectures and go to some repair shop to
rewrite his class notes in a format he can understand and based on what
the professor/instructor has emphasized, and to use the assigned text only
as a reference.
Do: Robert returns to his original schedule of studying. However, instead of
spending a majority of her time poring over the text, he rewrites and studies
his notes. He goes to the text only when he does not understand his notes.
When Robert takes one of the old exams, he finds that he has done better,
but he still sees room for improvement.
Check: Robert now realizes that he has been spending too much time
reading unimportant information in the required text. He knows that his
new approach works much better, yet he still feels that he needs more
studying time. He is unsure what to do, because he doesn't want to take
away from his social and physically active life.
Act: Robert decides to continue with his new studying approach while
attempting to find time in his busy day to study more.
Cycle 3
Plan.: In his search for more time to study, Robert realizes that there are
many places that he can combine exercising and socializing with studying.
First, he decides to study his rewritten notes while he is exercising on the
repair shop. Next, he intends to spend part of his socializing time studying
with his friends.
Do: Robert's friends are excited about studying together, and their sessions
turn into a fun and helpful use of everyone's time. Robert has found that he
enjoys studying while he exercises. In fact, he discovers that he remains on
the repair shop longer when he's reading over his notes. When Robert takes
his exams this week, he is happy to find that his grades are significantly
higher.
Check: Robert now knows that studying does not mean being locked up in
his room reading hundreds of pages of text. He realizes that he can gain a
lot by studying in different environments while focusing on the most
important points.
17
Act: Robert chooses to continue with the changes he has made in his
studying habits. What Robert initially thought would be an improvement
turned out to only discourage his further. Many people who are in Robert's
place do not take the time to study their changes and continue them even
though they lead down a disheartening path. By using the PDCA cycle,
Robert was able to see that his initial change did not work and that he had
to find one that would better suit him. With perseverance and the
willingness to learn, Robert was able to turn a negative outcome into a
positive improvement experience.

Try to answer all the Self Check materials without looking at the information sheet.
  • 19. 14 INFORMATION SHEET 2.1 The PDCA cycle USE The PDCA cycle is designed to be used as a dynamic model. The completion of one turn of the cycle flows from the beginning of the next. Following in the spirit of continuous quality improvement, the process can be realized and a new test of change can begin. This continual cycle of change is represented by the ramp of improvement. Using what you learn in one PDCA, you can begin another more complex trial. Plan. It is a change or a test, aimed at improvement. In this phase, analyze what you intend to improve, looking for areas that hold opportunities for change. The first step is to choose areas that offer the most return for the effort you put in-the biggest bang for your buck. Do. It is to carry out the change or test (preferably on a small scale). Implement the change you decided on in the plan phase. Check or Study the results. The basic questions are: What was learned? What went wrong? This is a crucial step in the PDCA cycle. After you have implemented the change for a short time, you must determine how well it is working. Is it really leading to improvement in the way you had hoped? You must decide on several measures with which you can monitor the level of improvement. Run Charts can be helpful with this measuring instruments.
  • 20. 15 Act. It is to adopt the change, abandon it, or run through the cycle again. After planning a change, implementing and then monitoring it, you must decide whether it is worth continuing that particular change. If it consumed too much of your time, was difficult to adhere to, or even led to no improvement, you may consider aborting the change and planning a new one. However, if the change ads to a desirable improvement or outcome, you may consider expanding the trial to a different area, or slightly increasing your complexity. This sends you back into the Plan phase and can be the beginning of the ramp of improvement. Example 1: The Student with Poor Grades in NCII Examination Robert is a graduate student in a vocational high school who has just taken his first set of examinations and is very unhappy with the results.  What is he trying to accomplish? Robert knows that he needs to improve his studying skills in order to gain a better understanding of the material.  How will he know that a change is an improvement? Robert considers the most important measure of his study skills to be his NCII holder. However, he does not want to risk another examination period just to find out that his skills are still not good. He decides that a better way to measure improvement is by taking old exams for the NCII.  What changes can he make that will result to improvement? Robert thinks that he has spent too little time studying. He feels that the best way to improve his study skills is by having an ample time. Cycle 1 Plan: Robert decides to add an additional thirty hours per week to his already busy schedule. He resolves that he must socialize less, get up earlier, and stay up later. At the end of the week he will take an old exam to see how he is progressing. Do. By the end of the week, Robert finds that he was able to add only fifteen hours of studying. When he takes the exam he is dismayed to find that he does no better. Check: The fifteen extra hours of studying has made Robert feel fatigued. In addition, he finds that his ability to concentrate during those hours is rather limited. He has not exercised all week and has not seen any of his friends. This forced isolation is discouraging him. Act: Robert knows that there must be another way. He needs to design a better, more efficient way to study that will allow his time to exercise and socialize.
  • 21. 16 Cycle 2 Plan: Robert contacts all his technical/technology school friends whom he knows are doing well yet still have time for outside lives. Many of these friends have similar advice that Robert thinks he can use. Based on his findings, he decides to always attend lectures and go to some repair shop to rewrite his class notes in a format he can understand and based on what the professor/instructor has emphasized, and to use the assigned text only as a reference. Do: Robert returns to his original schedule of studying. However, instead of spending a majority of her time poring over the text, he rewrites and studies his notes. He goes to the text only when he does not understand his notes. When Robert takes one of the old exams, he finds that he has done better, but he still sees room for improvement. Check: Robert now realizes that he has been spending too much time reading unimportant information in the required text. He knows that his new approach works much better, yet he still feels that he needs more studying time. He is unsure what to do, because he doesn't want to take away from his social and physically active life. Act: Robert decides to continue with his new studying approach while attempting to find time in his busy day to study more. Cycle 3 Plan.: In his search for more time to study, Robert realizes that there are many places that he can combine exercising and socializing with studying. First, he decides to study his rewritten notes while he is exercising on the repair shop. Next, he intends to spend part of his socializing time studying with his friends. Do: Robert's friends are excited about studying together, and their sessions turn into a fun and helpful use of everyone's time. Robert has found that he enjoys studying while he exercises. In fact, he discovers that he remains on the repair shop longer when he's reading over his notes. When Robert takes his exams this week, he is happy to find that his grades are significantly higher. Check: Robert now knows that studying does not mean being locked up in his room reading hundreds of pages of text. He realizes that he can gain a lot by studying in different environments while focusing on the most important points.
  • 22. 17 Act: Robert chooses to continue with the changes he has made in his studying habits. What Robert initially thought would be an improvement turned out to only discourage his further. Many people who are in Robert's place do not take the time to study their changes and continue them even though they lead down a disheartening path. By using the PDCA cycle, Robert was able to see that his initial change did not work and that he had to find one that would better suit him. With perseverance and the willingness to learn, Robert was able to turn a negative outcome into a positive improvement experience.
