      Determining sigma levels of processes (one sigma, six sigma, etc.) allows process performance to be compared throughout an entire organization, because it is independent of the process. It is merely a determination of opportunities and defects, however the terms are appropriately defined for that specific process.Sigma is a statistical term ...

      One of the Six Sigma concepts used to accomplish this shift in perspective is defining defects based on “opportunities” rather than units; hence, performance is specified in terms of million opportunities (defects per million opportunities, or DPMO, where a "defect opportunity is a process failure that is critical to the customer ...

      Sigma – the overlap is directly between the two nuclei. Every bond contains one (and only one) sigma bond. Pi – the overlap is above and below the sigma bond. These are formed by the overlap of unhybridized p orbitals. There is one sigma bond and one pi bond in a double bond. There is one sigma bond and two pi bonds in a triple bond.

(Figs. 1.20, 1.21 in text) Because rotating a pi bond by 90° destroys the orbital overlap, there is a large barrier to rotation and for all practical purposes double bonds cannot ...

      The element, carbon, is one of the most versatile elements on the periodic table in terms of the number of compounds it may form. It may form virtually an infinite number of compounds. This is largely due to the types of bonds it can form and the number of different elements it can join in bonding. Carbon may form single, double and triple bonds.
