"I worked with David [of Zener Engineering Services] on a project to deliver an ABB 800XA DCS system for a Blue Chip Pharmaceutical company. He was the QA lead for the supplier.

We jointly reviewed and approved a very large FAT document set in lieu of a reduced SAT and OQ. David's approach is very professional, critical, but crucially pragmatic.

I enjoyed working with him and would welcome any future opportunities to do so."

"I briefly worked with David of Zener Engineering Services, when he was engaged as a validation manager.

David is an accomplished validation engineer and works to a high standard expected within the regulated environment.
