PDCA Cycle

Plan, Do, Check, Act (PDCA)  is a well-known and respected approach to helping teams plan and implement a solution to a problem, often testing it on a micro scale and reviewing the results before agreeing how to proceed.

PDCA encourages an engaged, problem-solving workforce – the method is not limited to managers, but can be used across the organizational structure, using combined knowledge and experience. This helps business to innovate through creative problem solving.

Although it stimulates organizational problem solving, PDCA is not a problem solving approach as such. It is more of a planning and implementation method. It can be used as part of other problem solving techniques like Six-Step Problem Solving or Simplex.

The easiest way to think of it is a prototyping model. But it can be used for larger projects, where testing is not feasible – for example, if a business has already bought new, expensive equipment to solve a problem, then the implementation has to be on a large scale.

Usually the Problem Solving Group (PS) has already identified what they want to solve and the changes they would like to make. This may include how outcomes will be measured, or a specification. PDCA would then drop into any planning and implementation phases.

The method comprises four steps:

Plan This first stage clarifies the objectives of the chosen solution, and will identify which processes need to change (the problem will have already been defined, and a solution proposed using other problem solving techniques).  

The PS group will plan how the solution is tested, and forecast what is expected to happen during the PDCA the cycle. This will result in a set of outputs, and usually set a baseline for improvement.

 Focused work at this stage includes agreeing what data is to be collected, what Resources are needed, and the actions that will take place and when. The PS group will then decide where the trial run will be held. At this stage ‘before’ data is collected for later comparison in the ‘Check’ step.

Do

This involves physically implementing the solution, and collecting data for analysis in the next step, observation and project management.

This step should also include oversight to ensure that the solution is implemented as per the specification.

Check

This step is about analyzing ‘before’, ‘during’, and ‘after’ data to see what can be learned. (Another name for this step is ‘Study’). ‘During’ data is easy to overlook, but any plan is implemented in phases, and if issues are to be found and identified quickly, these actions need to be measured.

Not only will the process be observed qualitatively as well as quantitatively, feedback can be gathered from the end users of the solution.

Act

If the ‘Check’ demonstrates that the ‘Plan’ phase was implemented effectively and improvements can be seen on the baseline, then a new baseline is created and the cycle returns to ‘Plan’, using the new baseline.  If ‘Check’ results infer that there has been no improvement from the ‘Do’ phase, then the existing baseline continues in place. In either scenario, if ‘Check’ reveals something different from expected (whether it has out-performed or underperformed), then it identifies that more Learning is needed.

Personnel policies

Personnel policies are guidelines that an organization or company creates to manage its workers. Personnel policies describe the type of job performance and workplace behavior an organization expects from its employees, and what type of compensation and opportunities for advancement it is offering in return. The rules, requirements, benefits and opportunities outlined in personnel policies are often viewed as a reflection of an organization’s values and goals.

The Basics

Although personnel policies vary from company to company, most written policies are general rules that apply to all employees rather than specific job requirements for individual workers. Some of the most basic information includes the number of hours employees are expected to work each day, starting times, the amount of time allowed for breaks and lunch, and the number of sick days, personal days and vacation days each worker is entitled to take with pay each year.

Compensation

Personnel policies also describe the pay employees can expect for their work, although often salary or pay levels or tiers are used rather than specific dollar amounts. Payroll schedules and whether employees are paid weekly or bi-weekly, opportunities to work overtime, pay raises, and what a manager may consider during an employee evaluation are also usually included. Companies also explain what type of Health care benefits are offered for workers, and how much each individual is expected to contribute for that insurance. Reimbursement for mileage traveled in an employee’s personal vehicle, on-the-job expenses such as special clothing, and Education that enhances an individual’s job performance are usually discussed as part of a company’s compensation package.

Supervisors and Grievances

The chain of command or who supervises an employee on the job should also be part of a personnel policy. Many employers clearly state specific actions or behaviors that are unacceptable in a workplace and the types of discipline workers can expect from supervisors if those rules are broken. However, most personnel policies also include a grievance process that explains how employees can appeal a supervisor’s disciplinary decision if they feels it is unfair.

EMPLOYMENT Law

Although employers can fill personnel policies with other requirements and benefits, in some cases, policy is determined by federal employment laws. For example, an employer can choose to pay its workers $100 an hour. However, an employer must, in most cases, pay a worker at least the federal minimum wage or the state minimum wage if it is higher. According to the Family and Medical Leave Act, a company with 50 or more employees must allow any worker who has been on the job for 12 months to take a 12-week leave of absence for the birth or adoption of a child, for a serious illness or an emergency involving the military service of a family member. The Equal Opportunity Commission enforces federal laws that prohibit an employer from discriminating against a worker based or her race, sex, religion or national origin.

Goals

Personnel policies are, in part, the result of a post-World War II movement that looked at the emerging field of organizational psychology and tried to apply certain rules to workers to make Industry more productive and efficient. During the 1960s and ’70s, the field of human resources began paving a more humane and socially aware approach to personnel policies that emphasized a worker’s sense of safety, well-being and opportunity as a means to achieve greater productivity. Beyond productivity, writers like Jette Louise Flensburg, organizations such as the Human Rights Campaign and scholars like Matt Huffman at the University of Santa Barbara believe personnel policies have the ability to create and foster Equality among workers.

The PDCA cycle is a four-step process that can be used to improve any process. The steps are:

  1. Plan: Identify the problem or opportunity, and develop a plan to address it.
  2. Do: Implement the plan and collect data on the results.
  3. Check: Analyze the data to see if the plan is working.
  4. Act: Make changes to the plan as needed, and repeat the cycle.

The PDCA cycle is a continuous improvement process that can be used to improve any process. It is a simple and effective way to make sure that your processes are always getting better.

Here are the sub topics of PDCA Cycle:

  • Plan:
    • Identify the problem or opportunity.
    • Develop a plan to address it.
    • Set goals and objectives.
    • Identify resources needed.
    • Develop a timeline and budget.
  • Do:
    • Implement the plan.
    • Collect data on the results.
    • Communicate with stakeholders.
  • Check:
    • Analyze the data to see if the plan is working.
    • Identify areas for improvement.
    • Make changes to the plan as needed.
  • Act:
    • Implement the changes to the plan.
    • Collect data on the results.
    • Communicate with stakeholders.
    • Repeat the cycle.

Plan

The first step in the PDCA cycle is to plan. This involves identifying the problem or opportunity that you want to address, and developing a plan to address it. The plan should include goals and objectives, resources needed, a timeline, and a budget.

Do

The second step in the PDCA cycle is to do. This involves implementing the plan that you developed in the first step. As you implement the plan, you should collect data on the results. This data will help you to determine if the plan is working.

Check

The third step in the PDCA cycle is to check. This involves analyzing the data that you collected in the second step. The data will help you to determine if the plan is working. If the plan is not working, you will need to make changes to it.

Act

The fourth and final step in the PDCA cycle is to act. This involves making changes to the plan as needed. The changes should be based on the data that you collected in the third step. Once you have made the changes, you will need to go back to the first step and start the cycle again.

The PDCA cycle is a continuous improvement process. This means that you should always be looking for ways to improve your processes. You can do this by collecting data, analyzing the data, and making changes to the plan as needed.

The PDCA cycle is a simple and effective way to improve any process. It is a process that can be used by anyone, regardless of their experience or expertise. If you are looking for a way to improve your processes, the PDCA cycle is a great place to start.

Here are some examples of how the PDCA cycle can be used:

  • A company can use the PDCA cycle to improve its manufacturing process.
  • A school can use the PDCA cycle to improve its teaching methods.
  • A government agency can use the PDCA cycle to improve its customer service.

The PDCA cycle can be used to improve any process, regardless of the size or complexity of the process. It is a simple and effective way to make sure that your processes are always getting better.

What is a hypothesis?

A hypothesis is a statement about the relationship between two or more variables. It is a tentative explanation for something that is observed.

What is a theory?

A theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.

What is a law?

A law is a statement that describes an observed regularity in the world. It is a description of what happens, not an explanation of why it happens.

What is the difference between a hypothesis and a theory?

A hypothesis is a tentative explanation for something that is observed, while a theory is a well-substantiated explanation of some aspect of the natural world. A hypothesis is tested by experiment, and if it is supported by the evidence, it may become a theory.

What is the difference between a law and a theory?

A law is a description of what happens, not an explanation of why it happens. A theory is an explanation of why something happens.

What is the scientific method?

The scientific method is a process for experimentation that is used to explore observations and answer questions. Scientists use the scientific method to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to vary in a predictable way. Just like with any experiment, the scientific method starts with a question.

What are the steps of the scientific method?

The scientific method is a series of steps followed to answer a question or solve a problem. The steps include:

  1. Ask a question.
  2. Do background research.
  3. Construct a hypothesis.
  4. test the hypothesis by conducting an experiment.
  5. Analyze the data and draw a conclusion.
  6. Communicate the results.

What is the difference between qualitative and quantitative data?

Qualitative data is descriptive and cannot be easily quantified. Quantitative data is numerical and can be easily measured.

What is the difference between independent and dependent variables?

The independent variable is the variable that is changed by the experimenter. The dependent variable is the variable that is observed to see how it changes in response to the changes in the independent variable.

What is a control group?

A control group is a group of subjects in an experiment who do not receive the treatment being tested. The control group is used to compare the results of the treatment group to see if there is a difference.

What is a confounding variable?

A confounding variable is a variable that is not being studied but that could affect the results of the experiment. Confounding variables can be controlled for by using randomization or by using a control group.

What is a statistical significance?

Statistical significance is a measure of how likely it is that the results of an experiment are due to chance. A statistically significant result is one that is unlikely to have occurred by chance.

What is a p-value?

A p-value is a measure of the Probability of obtaining the results of an experiment if the null hypothesis is true. The null hypothesis is the hypothesis that there is no difference between the groups being compared. A p-value of less than 0.05 is considered statistically significant.

What is a confidence interval?

A confidence interval is a range of values that is likely to contain the true value of a Population parameter. The confidence level is the probability that the confidence interval contains the true value of the population parameter. A confidence interval of 95% means that there is a 95% chance that the confidence interval contains the true value of the population parameter.

What is a hypothesis test?

A hypothesis test is a statistical procedure that is used to test a hypothesis about a population parameter. The null hypothesis is the hypothesis that there is no difference between the groups being compared. The alternative hypothesis is the hypothesis that there is a difference between the groups being compared. The p-value is a measure of the probability of obtaining the results of the experiment if the null hypothesis is true. A p-value of less than 0.05 is considered statistically significant.

What is a type I error?

A type I error is the error of rejecting the null hypothesis when it is true. The probability of a type I error is denoted by $\alpha$.

What is a type II error?

A type II error is the error of failing to reject the null hypothesis when it is false. The probability of a type II error is denoted by $\beta$.

What is power?

Power is the probability of rejecting the null hypothesis when it is false. The power of
