Can you explain the PDCA cycle and where testing fits in?

PDCA is a four step problem solving process. It is also known as the Deming cycle, Shewhart cycle or Deming wheel.The following are the explanation of each step:

1. P - Plan (Devise your Plan). Recognize an opportunity and plan a change.

2. D – Do (or Execute) the Plan. Implement change and Test the change. Carry out a small-scale study.  Testing fit in this stage.

3. C – Check (Check the Results). Review the test, analyze the results and identify what you’ve learned.

4. A - Act (Take the necessary action) Take action based on what results are found: If the change did not work, go through the cycle again with a different plan. If you were successful, incorporate what you learned from the test into wider changes. Use what you learned to plan new improvements, beginning the cycle again.

Software testing is an important part of the software development process. In normal software development there are four important steps, also referred to, in short, as the PDCA (Plan, Do, Check, Act) cycle.Let's review the four steps in detail.

1. Plan: Define the goal and the plan for achieving that goal.
2. Do/Execute: Depending on the plan strategy decided during the plan stage we do execution accordingly in this phase.
3. Check: Check/Test to ensure that we are moving according to plan and are getting the desired results.
4. Act: During the check cycle, if any issues are there, then we take appropriate action accordingly and revise our plan again.

So developers and other stakeholders of the project do the "planning and building," while testers do the check part of the cycle. Therefore, software testing is done in check part of the PDCA cyle.

PDCA cycle stands for Plan Do Check Act; commonly used for quality control.Plan: Identify aim and procedure necessary to deliver the output.Do: Implement the plan.Check: Confirm if the result is as per plan.Action: Take appropriate action to deceiver expected outcome. Which may also involve repeat the cycle.

PDCA (plan-do-check-act) is a repetitive 4-stage model for continuous improvement (CI) in business process management. This cycle is repeated again & again and has no end. 

The steps (as taken from internet which describes best) are as below:

1. Plan. Recognize an opportunity and plan a change.
2. Do. Test the change. Carry out a small-scale study.
3. Check. Review the test, analyze the results and identify what you’ve learned.
4. Act. Take action based on what you learned in the study step: If the change did not work, go through the cycle again with a different plan. If you were successful, incorporate what you learned from the test into wider changes. Use what you learned to plan new improvements, beginning the cycle again.

Software testing is an important part of software development process. In normal software development below are the four important steps and also referred in short as the PDCA cycle.Let’s try to understand the above four steps in detail fashion.Plan: - Define your goal and the plan of how you will achieve that goal.Do / Execute: - Depending on the plan strategy decided during the plan stage we doexecution accordingly in this phase.Check: - Check / Test to make sure that we are moving according to plan and we aregetting the desired results.Act: - During the check cycle if any issues are there then take appropriate actionaccordingly and revise your plan again.

Dear Sir, I would like to inform you that -explain-the-pdca-cycle-and-where-testing-fits-in A four-step problem-solving iterative technique used to improve business processes. The four steps are plan-do-check-act. The PDCA Cycle can be used to effect both major performance breakthroughs as well as small incremental improvements in projects and processes. Also known as the Deming wheel or Shewhart cycle

Software testing is an important part of the software development process. In normal software development there are four important steps, also referred to, in short, as the PDCA (Plan, Do, Check, Act) cycle.Let's review the four steps in detail.

(i)Plan: Define the goal and the plan for achieving that goal.

(ii)Do/Execute: Depending on the plan strategy decided during the plan stage we do execution accordingly in this phase.

(iii)Check: Check/Test to ensure that we are moving according to plan and are getting the desired results.

(iv)Act: During the check cycle, if any issues are there, then we take appropriate action accordingly and revise our plan again.

So developers and other stakeholders of the project do the "planning and building," while testers do the check part of the cycle. Therefore, software testing is done in check part of the PDCA cyle.

P – Plan: a test that is aimed at improvement. D – Do : Carrying the test. C – Check: Leads to the results of issues, fixes A – Act: Adopting the change. PDCA cycle is designed for using as a dynamic model for testing. After completing the turn of one cycle leads to begin the next cycle. Followed by the continuous quality improvement, the process can be reanalyzed and a new test change begins. The continual cycle of change is represented for the ramp of improvement

This Process in used for Quality improvement and normally used in Manufacturing industries and also used for Projects.
