DEFINITIONS AND CAUTIONARY NOTE The compa nies in which Roya l Dutch Shell plc directly a nd indirectly owns investments a re sepa ra te entities. In this presenta tion “Shell”, “Shell group” a nd “Roya l Dutch Shell” a re sometimes used for convenience where references a re ma de to Roya l Dutch Shell plc a nd its subsidia ries in genera l. Likewise, the words “we”, “us” a nd “our” a re a lso used to refer to subsidia ries in genera l or to those who work for them. These expressions a re a lso used where no useful purpose is served by identifying the pa rticula r compa ny or compa nies. ‘‘Subsidia ries’’, “Shell subsidia ries” a nd “Shell compa nies” a s used in this presenta tion refer to compa nies over which Roya l Dutch Shell plc either directly or indirectly ha s control. Compa nies over which Shell ha s joint control a re genera lly referred to “joint ventures” a nd compa nies over which Shell ha s significa nt influence but neither control nor joint control a re referred to a s “a ssocia tes”.

critical issues the University has established a Quality Assurance Directorate, which is mandated to develop a Quality Assurance Framework and a Quality Assurance Policy. The Quality Assurance Framework would clearly spell out the Principles, Guidelines and Procedures for implementing institutional quality assurance processes.
Quality assurance or software quality assurance is an integral part of the development process and is used in the IT industry by quality assurance professionals as well as testers. Quality assurance is associated with the concept of dependability. Dependability is, first, a guarantee of increased cybersecurity, reliability and

AAMI HE75, Human factors engineering – Design of medical devices, Clause 9, Usability Testing, provides an excellent guide to the types of formative evaluations that are useful in early device UI development such as cognitive walkthroughs, heuristic evaluations, and walk-through-talk-through usability tests. Annex D of IEC 62366 also provides descriptions of these formative techniques .
