This paper highlights the practical benefits to the industry, of adopting the concept of the Spectrum of Importance (SOFI) an alternate approach to understanding and prioritizing process parameters. This approach represents a move away from the current binary critical/non-critical one that is widely used by many companies today; instead, it...
