1. How is Six Sigma approach to process improvement different than other process improvement approaches? What is the primary business driver for using Six Sigma in a business? Why? Answer: The aspects that differentiate Six Sigma from other process improvement approaches is that it depends on data and statistics to make decisions, focuses on continuous improvement, uses many problem-solving tools. The primary business driver differs for the type of business. Businesses noticed that improving quality in their processes would save them money and attain better results by reducing errors and defects, which is the primary driver. Other drivers could be customer satisfaction by reducing defective services and products, gaining market competency, etc. Therefore, Six Sigma is one of the common methods that is utilized to find ways and opportunities for quality improvement. 2. What are the main applications of DMADV and IDOV versus traditional DMAIC? How do they differ? Answer: DMADV applications and differences: A variant of Design for Six Sigma (DFSS) that is used for developing new processes, products, business. It defines customer needs basing on services and products. It is to develop the business model such that it fulfills customer requirements and needs. IDOV applications and differences: A variant of Design for Six Sigma (DFSS) that is also used for designing new processes, products, business. Also, to focus on the financial aspects of the organization and customer satisfaction. DMAIC applications and differences: A traditional method that is an integral part of Six Sigma and can be used as a standalone quality improvement process on its own. It is used for improving existing processes. It is to improve the business process to decrease or get rid of the defects. ------------------------------- 1. How is Six Sigma approach to process improvement different than other process improvement approaches? What is the primary business driver for using Six Sigma in a business? Why? Six Sigma is a measurement-based strategy that focuses on data and statistics in comparison to other process improvement approaches. It’s a methodology which aims at improving process and increasing customer satisfaction. The primary business diver for using Six Sigma in a business is to ensure better results by minimized errors and detect them in an early stage. This reduction leads to consistent and desired outcomes from processes. 2. What the main applications of DMADV and IDOV versus traditional DMAIC? How do they differ? DMADV: This model mainly focuses on the development of a new service, product which is useful when implementing new strategies and initiatives because of its basis in data, early identification of success, and thorough analysis. Within DMADV, the Design and Verify steps deal with redesigning a process to match customer needs. IDOV: This methodology is used for designing products and services to meet six sigma standards that consist of Identify, Design, Optimize, and Verify. These four phases parallel the four phases of DMAIC, MAIC – Measure, Analyze, Improve, and Control. Compared to the other two methods, It is more focused on meeting the financial goals of the organization. DMAIC: It is an integral part of the Six Sigma Quality Initiative that refers to a data-driven quality strategy for improving processes. It is used on an existing product or process that is no longer meeting customer needs or specifications.
