Six Sigma Concrete: A new standard for high quality

Systems and ideologies, such as the three sigma rule or lean six sigma, are used by companies to improve the quality and efficiency of their product manufacturing while minimizing defects and waste. Usage of the word “sigma” traces back to the mathematical concept of standard deviation (σ), and it is a way to define outliers or, in manufacturing categories, defects. The implementation of these “sigma methodologies” evokes a sense of quality and excellence, and therefore combining the word “sigma” and concrete is a creative way to represent high quality concrete. Furthermore, there are six specific attributes of concrete, all starting with the letter “S”, that directly contribute to high quality.
