Six Sigma Part 3: DMADV Methodology

DMADV is the six sigma methodology focusses on the development of new method to reduce error as compared to the existing process. It stands for Define, measure, analyze, design and validate.


The DMADV methodology should be applied:

[1] When there is new product or process to be developed in the industry.

[2] When the existing process need to change to meet the customer need and principles of Six sigma.

Each terminology in acronym is a stage of process, defined as below:

[1] Define: Define the process and design goals.

[2] Measure: Measure and identify critical quality characteristics of the product. This may include the overall risk and production capabilities.

[3] Analyze: Analyze the collected date from the measurement to find the best design.

[4] Design: Design the new product, process or service to replace the existing one.

[5] Validate: Validate the final designed process, product or service for customer satisfaction and six sigma principles.

DMADVO is the extension of DMADV including the step for the optimization of new design created.

Static Assumption of Dynamic Conditions

Image
Mathematics is a beautiful subject; solving the differentiation, Integration, and differential equation is pretty fun. The same applied to the application of Mathematics (primarily calculus) to Physics. However, some mathematical equations can’t be solved and sometimes become a nightmare for the physicist. These equations can be solved through certain assumptions, sometimes excluding three dimensions and sometimes time. In Mechanical Engineering and other related domains, Dynamic conditions are encountered most of the time. It is a condition where the parameters vary with time, and we can’t ignore time in a particular situation. These conditions make mathematical equations quite complex and impossible to solve. Hence, the assumption of static for such dynamic conditions is required. Static condition is the condition where the parameter either does not vary with time or varies very slowly with time, such that the time parameters can be ignored. All the dynamic conditions can’t be assume...
