About Half of the speakers so far have mentioned feed-back of user experience. Unquestionably, if we are to make real advances in reliability, Industry must be fed with comprehensive and timely data on the behaviour of its products in Service, and most of us would agree that the systems for data retrieval which exist today fall short of this requirement. It is inevitable, I suppose, that by the time we disperse from this meeting a number of problems within the whole field of reliability—whether to do with rig testing, responsibilities of sub-contractors, statistical prediction, contractual procedures, etc.—will have been thoroughly aired but not always with general agreement on them and in most cases without any feasible solution or break-through having been proposed. I suggest that the particular field of data feed-back is one where the requirement is almost unanimously agreed and where profitable and constructive steps forward are both identifiable and feasible.
