Process Capability and Control is a structured and robust methodology that enables a broad range of companies to achieve manufacturing excellence in today's highly challenging market environment. PC&C is also a key element in Tunnell's broader Process Analytical Technology (PAT) approach for pharmaceutical firms, which fully responds to FDA's request for "systems for continuous analysis of manufacturing processes based on real-time measurements." Tunnell Consulting has already applied PC&C with exceptional results in six pharmaceutical firms, helping these clients achieve superior operational and quality results while reducing compliance exposure. PC&C drives down process variation and improves such quality measures as Cpk (the degree of performance to specification), to yield fewer lost batches, fewer deviations, increased throughput, and lower compliance risk. PC&C is the result of Tunnell's 40 years of experience in implementing practical solutions in manufacturing, using strategies such as Statistical Process Control (SPC), Design of Experiments (DOE) and Six Sigma. This experience, along with our technical knowledge, notably in the pharmaceutical field, has enabled us to develop the proven and innovative PC&C approach.
