The two most commonly used Six Sigma methodologies are DMAIC and DMADV. Both methods are designed to make the business process more efficient and effective. Although both methodologies share some important features, they are not interchangeable and are designed for use in different business processes. Unless your teammates understand the purpose of using Six Sigma strategies, Six Sigma Principles implementing those into their team’s efforts would not be possible. Before comparing these two approaches in more detail, let’s review the meaning of the acronyms.

Six Sigma Green Belts, Black Belts, and Master Black Belts and are used to reduce defects to less than 3.4 per million available opportunities, or Six Sigma. Difference between dmaic and dmadvDespite the first three shared letters of their names, there are some notable differences between them. DMAIC typically defines a business process and how it applies; DMADV defines customer needs as they relate to a service or product. With regard to measurement, DMAIC measures the current performance of a process, while DMADV measures customer specifications and needs. DMAIC focuses on making improvements to a business process to reduce or eliminate defects. DMADV develop an appropriate business model to meet customer requirements. When should DMAIC and DMADV be used? In general, DMADV is associated with new product services and projects; may not always work with existing products and processes. Another way to see this would be to use DMADV when a process improvement does not meet expectations or simply fails. DMAIC is used in an existing product or process but no longer meets customer needs and/or specifications. Companies with no prior experience in Six Sigma may want help from professionals like Six Sigma Black Belts and Master Black Belts, Green belt professionals who can help you make the best choice between DMAIC and DMADV. What are the benefits of DMAIC?DMAIC is a common technique in Six Sigma, a process improvement methodology that focuses on improving quality and reducing defects in any process. Dmaic model is a systematic five-step approach that enables you to effectively manage process improvement projects. The acronym DMAIC stands for defining, measuring, analyzing, improving and controlling the steps of this Six Sigma technique. Phases Explained In the “define” phase, you try to understand the problem by determining existing performance against expectations. In the “measure” step, you build a detailed process map, collect specific data, and determine the method to execute the process. The goal of the “analyze” phase is to find out the real causes of the process performance problem. In the “improve” step, you test and implement solutions that address the root causes. Through the “control” phase, you ensure that the gains made in the “improve” phase continue. Six Sigma Benefits Six Sigma is not so different from most other process improvement methodologies. According to “Process Improvement Using Six Sigma: A DMAIC Guide”, while Six Sigma has a broad set of tools associated with it, the Six Sigma process has a proven framework that delivers results. Six Sigma also comes with a very effective process improvement technique, the DMAIC methodology.

This means that he carefully analyzes a process before attempting or implementing improvements. One of the most common reasons why companies do not implement improvements is that the company does not perform analysis prior to implementing the improvement. This can result in a failure to properly deliver improvements and, in many cases, aggravate the existing system. Other DMAIC Benefits As a structured approach, DMAIC provides a business with a roadmap for solutions. This helps the company solve problems from start to finish while producing end results. In addition, DMAIC supports an analytical approach, allowing the company to use the collected data. This helps the company ensure accurate baselines. In addition, DMAIC enables a company to quantify improvements and find answers to complex problems. What does DMADV mean? We have seen that DMAIC means Define, Measure, Analyze, Improve and Control. Another improvement framework is DMADV and the first three letters of this framework are the same as in DMAIC and represent Define, Measure and Analyze respectively. However, the last two letters mean Design and Verify. The DMADV Framework * Measure and match performance with customer requirements; * Analyze and evaluate the design for the process, product or service; * Design and implement the matrix of new processes required for the new process, product or service; * Check results and maintain performance. The basic difference between the DMAIC and DMADV frameworks is that DMAIC will be used when you are trying to improve or develop an existing process. However, the DMADV (Define-Measure-Analyze-Design-Verify) method aims to redraw a problematic process or product. The approach initially follows the first three steps of DMAIC and then deviates into the last two steps, introducing the Design / Re-design and Verify or Validate steps for the necessary improvements. This approach prevents problems from happening through quality concepts and robust design. DMAIC and DMADV: What are the similarities and differences? To get a better idea of the differentiations between them, it is worth looking at a quick comparison according to some criteria: Usage situations DMAIC is best applied in situations where the product or process is present but not delivering the desired performance. DMADV, in turn, is recommended in contexts where elements are not present and have already been optimized, but still lack performance improvement. Practical relationship with strategiesWhile dmaic six sigma is designed to enhance a service, product, or process that the corporation intends to continue selling, DMADV works best for launching new projects or enhancements. Thus, it is necessary to align with business planning and use the data consciously, so that they can actually assist in achieving more satisfactory results. Imagine the following situation: The customer base is already large and the company – a food brand, for example – has to meet consumer demand for new solutions. In this case, it is valid to resort to DMADV, because it has the proposal to optimize this process. It is conceptually associated with the vision of the future.

Keeping aside the initial three letters of the two methodologies which have common meanings, the primary difference between them lies in the manner in which the last two steps take place.This means that if the firm is using DMAIC, the improvement and control steps emphasizes determining the means to readjust and control the process. In DMADV, the design and verify steps involve redesigning the process, so as to suit the needs of the customer. What is Six Sigma?A quality measure that works toward near perfection. It attempts to reduce variations in the process that causes defects. The underlying philosophy behind six sigma is to reduce process output variation. For this, we use a common metric to compare the performance of the process in terms of variability with different processes, which is Defects Per Million Opportunities (DPMO). The objective of this methodology is to substantially improve the process as well as the product design through a systematic process improvement strategy. The focus is on quality management, improvement and measurement. Further, DMAIC and DMADV are the two methodologies of six sigma Also Read: Difference Between Lean and Six Sigma This post elaborates on the differences between DMAIC and DMADV. Let’s have a look.

What is DMAIC?DMAIC is a six sigma model which the companies use to make improvements in the existing processes that are underperforming. That is their performance is not enough to meet the standard or level, as measured against critical to ‘x’ requirements. Here ‘x‘ denotes critical customer or stakeholder requirements in terms of:
Further, DMAIC is a fact-based, systematic and scientific methodology. It removes those steps which are not productive. Also, it concentrates on measurements and applies technology to make improvements. In this, improvements are made in quality on a project-by-project basis. DefineThis step involves:
Further, the improvement project is devised and planned. To work on this project a team is constituted and management support along with the required inputs are provided. MeasureAt this stage, the team will map out the existing process. Thereafter, determination of the critical to x characteristics of the process in which there is a need for improvement takes place. And for this, metrics for measuring the CTx characteristics are chosen, designed and confirmed. Besides, a data collection plan is made and data is collected from the existing process to ascertain the baselines and levels of variation for each metric that is chosen. Further, the information is helpful in the determination of the capability of the current process. As well as it defines the benchmark performance levels of the current process. AnalyseTo analyse the data, the team uses statistical tools right from the previous step. This is to completely understand the impact that each input variable has on the process and the consequent outputs. Further, the team will perform a gap analysis to assess the variance between current performance and desired performance. On the basis of these evaluations, identification and validation of the fundamental cause of the problem and/or variation in the process occurs. This step aims at understanding the process in such a manner that it is easy to explore multiple improvement actions, during the improvement stage. ImproveThis step involves consideration of various approaches to solve the problem and reduce the variations in the process. After that, the team:
Then the team agrees upon a particular approach which is the best one and makes plans to implement improvements. Further, prior to the implementation of the plan, the team must take the approval of the relevant authority. Also, a pilot study is undertaken to test the solution. And if the pilot study becomes successful, then the solution is implemented to the whole organization. But if the pilot study comes out as unsuccessful, repetition of suitable DMAIC steps as per the requirement takes place. ControlIn this step, standardization and regulation of the process that has been improved occur. Then, it implements controls to ensure that improvement gains are sustained in future also. It covers:
This will help in observing the process or the product to look for any future conditions that are not under the control of the management.

It tends to define new processes and products at Six Sigma quality levels. This model is also applied at the time of the optimizing current process or product that does not reach specified quality levels. DefineAt this step, the establishment of goals relating to the design activity takes place. While determining goals, one must keep in mind the needs of the shareholder and alignment with the organizational strategy. This step is the same as the define step in the DMAIC model. MeasureIt involves the ascertainment of the critical to x characteristics of the novel product or process. After that, metrics for measuring the critical to x characteristics are selected, designed and confirmed. And then the determination of the data collection plan for each selected metric takes place. AnalyseIn this step, the team will consider multiple approaches to designing the novel product or process. And then assessment with regard to cost, benefits, impacts, and risk of each alternative is performed by the team along with the study of trade-offs. After that, the team comes up with the best approach. DesignThe creation of advanced and detailed designs occurs at this stage. Along with that, the implementation and optimization of these designs take place. Also, the team develops a number of plans for the verification of the designs. VerifyVerification of a new process or product takes place to ensure that it fulfils the needs of the stakeholders. It covers simulations, pilot studies or tests. After that, the new process or product design is implemented the team will develop a strategy for project handoff to the owners of the process.
