Q is for....

Quality The totality of features and characteristics of a product or service which bear on its ability to satisfy stated and implied needs.
Quality Assurance Confirming the degree of excellence of a product or service, measured against its defined purpose. This might involve a number of techniques.  For documentation it might involve inviting informed comment; for software, a process of formal testing, trialling or inviting public feedback on a beta version; for hardware, performance against specified test; for management process, comparison with a standard such as BSI5000.
Quality Management System The complete set of quality standards, procedures and responsibilities for an organisation or location.
Quarter-Inch Cartridge A storage technology based on tape backup drives and cartridges, for backing up data on computer systems. There are a set of standards devised to enable tapes to be used with drives from different manufacturers. These QIC standards specify the length of tape, the number of recording tracks, and the magnetic strength of the tape coating, all of which determine the amount of information that can be written to the tape.
Query By Example A simple-to-use query language implemented on several relational database management systems. Using query by example, the user specifies fields to be displayed, inter table linkages, and retrieval criteria directly onto forms displayed on the screen. These forms are a direct pictorial representation of the table and row structures that make up the database. Thus, the construction of a query becomes a simple "check off" procedure from the viewpoint of the user.
Queued Access Method A programming technique that will minimise input/output delays by synchronising the transfer of information between the program and the computer's input and output devices.
Queuing Theory A modelling technique based upon the allocation of requirement to resources.  It will indicate whether the resources will meet with the anticipated level and distribution of demand.  Invariably delivered as a computer simulation it provides a prediction of resource requirements, generally mapped against time and business cycles.
Quick Win Possibly identified by applying the Pareto Principal during the initial stages of a Service Improvement Programme, a Quick Win describes an improvement in actual or perceived service quality, achieved within a short space of time with relatively little effort.  The most significant contribution to a Quick Win is likely to be common desire to understand the root cause of the lack of service quality and to initiate a corrective change.
