On the 24th of July, PPI’s Managing Director, Robert Halligan presented a 60-minute webinar on PPI’s Wedge Model™, an evolved model of the well-known Vee Model. The Wedge Model™ shows the products of design on the left-hand side of the wedge, and the products of system integration on the right-hand side, with a second time axis showing multiple builds, such as for Agile development, coming out of the screen. Subjects of and references for verification and validation are superimposed.
Verification answers the question “is the work product correct with respect to the inputs used to create it – usually meets requirements?” Validation asks, “is the work product what is needed?”.
Colloquially, verification is – have we done the job right, and validation is – have we done the right job?
Thank you to everyone that tuned in, we hope to see you at the next one! Follow PPI’s LinkedIn page to make sure you don’t miss the next one.
