A proper Six Sigma deployment includes the use of the Lean tools and strategies. Six Sigma is the umbrella deployment technique for implementing value-added enhancement tasks aligned with the enterprise wants of the organization. These targeted tasks goal Crucial to Quality (CTQ), Crucial to Schedule (CTS) and Vital to Value (CTC) alternatives inside a company. Six Sigma makes use of quite a lot of instruments and strategies, together with statistical (enumerative stats, the statistical course of management, designed experiments), drawback fixing, consensus constructing, and lean instruments. A given venture could not use the entire instruments, but most organizations discover they want many of the instruments at any given time.
Lean gives important strategies to eliminate waste from the process for the enhancement of buying needs and wants of the customers. As such, the Lean strategies present a vital technique of engaging in the Six Sigma targets. Equally, the Lean strategies require using knowledge, and statistics present the required strategies for knowledge evaluation. It's unfortunate that some Lean experts, and a few Lean Six Sigma applications, don't stress the essential significance of the statistical instruments of their evaluation since this lack of rigor will forestall tasks from realizing their full potential.
Comparison between Lean and Six Sigma tells that Lean is a philosophy of identifying and eliminating non-essential and non-value including actions to streamline manufacturing and thereby enhance high quality, whereas Six Sigma is a change administration methodology to handle, enhance, and or reinvent enterprise processes to restrict course of variations to 3.4 defects per million alternatives and thereby improve quality.
The basic difference between Lean and Six Sigma is that “Lean" is a philosophy and Six Sigma is a program. Lean makes an attempt to inculcate an organizational tradition change and everlasting habits change amongst staff, to eliminate waste, whereas Six Sigma is a methodological course of intervention that doesn't try to alter the organizational tradition or try an everlasting behavioral change amongst staff.
"Lean" identifies the necessity for a course of or exercise first and if the exercise provides worth tries to enhance on such exercise via improved process of the stream and enhancing productiveness. Six Sigma focuses particularly on eliminating the process of variations to improve the process capability.
Lean, as the title suggests breaks down processes to reveal bone essentials under its guiding principle that any activity or function that doesn't add worth constitutes waste that wants elimination.
Six Sigma, however, doesn't question whether or not the activity adds value and works under the guiding principle that any variation in existing process the output is a waste.
