Perceptions of Quality

Quite some ago Intergen's Development Steering Group (DSG, a small group of senior developers/architects) went on a 'retreat' to discuss issues affected the development team as a whole and plan some strategy. Among the items up for discussion was the issue of quality - how to achieve it, and, in order to decide that, what on earth quality actually is. You might be thinking: "That's easy. Quality is making something good" which is all very well until you are asked to define what makes a piece of software 'good'. Is it that the code is well written, well documented, that the design is clean, tidy and understandable, that the GUI looks pretty, that the GUI is easy to use, that the system meets user requirements? All of the above?
