What Can You Expect From Implementing Our Solution?

Before After
Quality is tested during the final control and release of a product.  Quality is built into the lifecycle of the product. 
Flexibility is limited (when a change is needed, the regulatory process is restarted).  Supports a flexible approach that allows for continuous improvement.  
There are challenges submitting a post-approval change management project due to undefined risk management. Quality and risk are embedded in the process, streamlining post-approval change.
