Document Summary

The systems engineering v model helps in communicating key concepts associated with the product development process. The path of the v provides a macroscopic view of the design, development, and verification processes. The v model illustrates that: total system requirements drive sub-system design and requirements; sub- system requirements drive component design and requirements, each element is broken down into finer sub-elements until the system is considered to be fully designed. The right-hand side is mostly serial and confirms that the design meets all requirements. Six sigma is a rigorous and disciplined methodology that uses data and statistical analysis to measure and improve a company"s operational performance by identifying and eliminating defects in manufacturing and service-related processes. Commonly, a six sigma process is defined as having 3. 4 defects per million. The main themes of the six sigma process are depicted in the figure below: The strength of six sigma is that decision-making is based on data and factual information.
