The second step is an analysis of this problem. The third step is the development of an experiment to test it. Some of the things to consider during this process includes: Problem Identification.
Ideally, this should be carried out on small-scale studies. Small-scale experiments allow us to learn quickly, adjust as needed, and are typically less expensive to undertake. Make sure that you measure the performance and collect the data necessary to make an evaluation later on.
Consider the following questions:. In this stage, take action based on what you learned in the study. If the change did not work, go through the cycle again with a different plan. If you were successful, incorporate what you have learned from the test into wider changes. Use what you have learned to plan new improvements and start the cycle again.
If your plan worked, you will need to standardize the process and implement it across the business. During this phase of the PDCA cycle, you should ask the following questions:.
Kaizen focuses on applying small, daily changes that result in major improvements over time. The PDCA Cycle provides a framework and structure for identifying improvement opportunities and evaluating them objectively. Using PDCA, an organization undergoing continuous improvement can create a culture of problem solvers and critical thinkers. A Lean Approach To Promoting Employee Suggestions Quality Progress This simple, low-tech approach maintains the visual process and easily communicates where each suggestion is in the PDCA process without the need for email, databases or other technological means.

This involves not only the goal setting and finding possible solutions, but also hypothesizing methods that can be used to reach the ultimate goal.
Another thing that needs special attention is defining the success metrics. This simply means a clear evaluation matrix is ideally to be set beforehand. Then, the solution s will be tested in the Do process. To detach the Do, there could be two steps: making the Do multiple To-Dos by splitting the task and defining them with a specific time, personnel, and steps, and collecting real-time data and feedback. Check includes analyzing the results and comparing them to the hypothesis in the Plan stage: how well the solution worked, how much the goal has been achieved, and whether the methods were proven feasible.
If there are any unexpected issues, you may also need to find the causes and possible solutions. It is applied successively to the processes that seek to improve continuously. In this context, planning, standardization, and documentation are essential practices and accurate measurements. Other factors addressed by the PDCA concept are the talents and skills of the professionals involved. But how can we define in a summarized and didactic way what is the PDCA cycle?
Here it goes:. PDCA is an acronym that gives name to a tool used in process quality management. Its focus is to solve problems by following the four phases indicated by its letters: Plan, Do, Check and Act. See also: 3 Tools for Quality Management and Processes.
It is the stage where we analyze the problems that we want to be solved, according to the following order:. Here, the PDCA concept is beginning to show: a structured and organized repetition to find solutions. There is no way to plan a solution to a problem without identifying its root cause, the root problem, the one that really is the initial reason for everything. For example, imagine that you discover a problem in your home: the light is not turning on in a certain room.
The answer is obvious, the bulb must have blown. You check the bulb and find out that it really has blown, but;. When checking the fuse box, you discover that the circuit breaker for that room is off. You conclude that when this happened, the light blew before the circuit breaker switched off. Usually this happens because of a power surge over the capacity of the circuit breaker. You go back to the room and notice that there are several devices connected to one outlet, through an adapter, which generated an overload in that circuit.
Finally, you discover that another outlet in that room, formerly used to connect items to the power grid, is blocked by a change in the layout of the furniture. At the beginning of this conversation, if someone had said that the light in the room was off because someone had changed the location of the furniture, would you consider that an appropriate response?
Possibly not, and so, this is why the 5 Whys method is so widely used.
