This book explains how SaaS works and lists and describes many common misconceptions and pitfalls that laboratories have about implementing Quality Management Systems (QMS). By walking the reader through all ISO 15189 Standards and describing each in detail, we can show how to implement them in common sense and meaningful ways. This book demonstrates to clinical laboratories how to combine the rigor of international standards with the inherent benefits of contemporary cloud-based software systems so that they can involve the entire laboratory in making quality a shared habit.
