HomeLean Six SigmaWhat is DMAIC methodology? Learn the 5 phases of it Show Thiago Coutinho 17/12/2017 - 10 mins de leitura In this guide, I want to introduce you to what is DMAIC methodology, a key aspect to the success of the Lean Six Sigma application. Well, to implement Lean Six Sigma we need to keep in mind its great goal: to optimize the way that processes happen. We have a script to bring conviction- the DMAIC methodology that points us in the right direction. Clearly, it is much easier to understand how we should conduct our projects, isn't it? What is DMAIC methodology?DMAIC is a methodology with well-defined steps for the structured resolution of problems with a focus on continuous improvement. It indicates what to achieve at each stage of the project and how to do it using a typical sequence of graphical, practical and analytical tools. Then, the sequence is divided into five phases: Define, Measure, Analyze, Improve and Control - hence the DMAIC method. The line of reasoning allows a technical and precise analysis of the whole problem, this avoids hasty conclusions and allows direct action in the root cause. In addition to the improvement in finances, the great secret of the DMAIC methodology is to unfold the planning phase. Greater the dedication in this phase, shorter the implementation time and the probability of errors. This mentality is essential. The importance of this planning moment can be seen in the fact that this method is divided into 5 steps, 3 of which are focused on the planning phases. To be very clear, I will explain how each phase happens. I also separated some questions that can guide you, as well as examples and concepts of the main tools used, phase by phase. DMAIC Define PhaseThe initial phase could not be another: here, you define what you expect from the project. When we evaluate the history of the problem it is necessary to establish its processes clearly. An important tip is to not let anxiety cause bad performance in this step. By going over this cycle, many frustrations may appear in the course of its development. Running the DMAIC methodology may take a few months, as it is necessary to go through all the steps. So, to ensure the commitment of the team throughout the process, and also to formalize all the information defined in this step, it is very important to prepare the project charter, which is a tool that we will talk about below. The project charter will contain where the problem happens, which indicator you will use, who your project team will be, what schedule, which will be the database used. So your entire project team and your sponsors will be within the scope. In order for you to find your goals more easily, some questions may guide you:
It's time to act! The stages count on already established processes, this collaborates for an efficient work. There are some tools that can help your tasks. To make it easier, I have separated some of these techniques - and their definitions - so that you already get used to these features. Check out:
Lean Six Sigma is a methodology that seeks to increase the profitability of companies through the improvement of their processes. Thinking about you and your career, we, at Think Lean Six Sigma, created a FREE Yellow Belt training in Lean Six Sigma.In this training, we will introduce you to the DMAIC method and all its 5 steps, namely: "Define, Measure, Analyze, Improve and Control. With this course, you will be able to develop small improvement projects within your area of expertise and work with Green Belts and Black Belts in support of the Lean Six Sigma program.

DMAIC Measure PhaseIn this phase of DMAIC methodology, we know and observe how things are going at the moment. In this step, you need to raise the potential causes of the problem and analyze the database. This will be done in two ways: a more quantitative and a more qualitative one. On the quantitative path, we will pick up the database, select an indicator and study its behavior through some statistical tools that will be quoted later. In the qualitative way, we will study the process more deeply, seeking to discover where the problem defined in the previous step occurs. Let's map the information that is important and that will help us identify the potential causes of the project. Your main objective in this stage should be to identify the potential causes, filtering the most important ones, that is, those that are priority, that generate more impact on the final results. But attention: choose the proper numbers for analysis because the goals are already defined. The idea is to establish the size of the problem - there is no reason to analyze too much data if they do not lead you to your goal. These questions can help you:
The main tools of the MEASUREMENT phase are:
DMAIC Analyse PhaseIn this step we analyze the measured data to allow us to know the current behavior. We must identify the root causes - also called vital X's - that affect the process significantly and generate variability in the result of interest - also called the Y variable. So you can prove them with facts and data, using graphs, analysis statistics and also qualitative tools. This phase is extremely important to the DMAIC methodology because it ensures that the cause chosen in the previous step that you prioritized, actually disturbs your process, compromising the outcome of your indicator. Answer these questions:
The main tools of the ANALYSE phase are:
DMAIC Improve PhaseIn this phase, we are going to test and execute the solutions to the problem. For each root cause studied and proven in the Analysis Phase, we identified an appropriate solution that will be implemented through an Action Plan. In addition, we verify the impact and results obtained with the implemented improvements. As you can imagine, an action plan does not run from day to night. So this is probably the most time consuming step of the DMAIC methodology, taking 30-40 days from a Green Belt project, or 40-60 days on a Black Belt project. During this phase of improvement, the Six Sigma team should present the new version of the process map, trying to eliminate everything that does not add value. To reach conclusions in an easier way, answer the questions:
The main tools of the IMPROVE phase are:
DMAIC Control PhaseControl is the last step of the DMAIC. At this point, it is important to monitor the results achieved after implementing the improvements and to establish controls that ensure the sustainability of the results. For this, it can be found from the simplest techniques, like the elaboration of procedures and Checklists, to more complex techniques, like the use of devices to the proof of errors and statistical control of processes. It is very important to stress at this stage the question of the sustainability of what has been achieved. Many people think only of demonstrating and valuing the results obtained, and forget to establish means to maintain them. Furthermore it is important to establish a Control Plan, so you will think of ways to ensure that these results are not lost. Some effective choices are: conduct standardization training, review procedures, and define how results will be measured from that point on. To see these results more clearly, the analysis of the returns and economic benefits achieved must also be carried out. To understand your results, answer the questions: Has the
The main tools of the CONTROL phase are:
