All my past experience shows that quality is not about rigorous procedures, extensive trainings or punishments for poor results. Quality is a mindset. Quality is orientation of mental energy.

You can not simply declare quality like "From now on we will built only high-quality products". Quality needs to be cultivated. Day in and day out. Quality should be your way of living. In everything you do set high quality bar and reach it. If even if nobody will see and appreciate it. You will appreciate your well done job.

Paul Stovell puts it just right about writing program code. But generally it is true for everything we do.
