Fitness for Use Definitions

Developing any product or service requires trade-offs that must be made consciously.

Quality has been defined as Fitness for Use as expected by the user.  This definition is, indeed, very broad with different users having different expectations.  Developing a product or service requires the consideration of many factors that, at times, may be at odds with each other.  To address the design considerations and simultaneously attempt to address all of the issues that a user may encounter, all involved parties need to consider all of the product’s or service’s characteristics and prioritize them accordingly.
