The Improvement of Processes’ Quality in Organisations Using The Six Sigma Concept

Six Sigma is a problem-solving methodology. In fact, it’s the most effective problem-solving methodology available for improving business and organizational performance. Bill Smith from Motorola first developed in 1986 the specific elements of Six Sigma. At the beginning, it was a set of practices which have been used in the manufacturing processes in order to eliminate the defects but, as time passed, the concept has been extended so as to be used in other types of businesses, too. The 6th Sigma level corresponds to a 99,9997% performance, respectively 3,4 defects per a million of occasions. A Six Sigma process is a re-designed business process and has three basic elements: Process Improvement; Designing/re-designing the process; The Process Management.
