Knowledge Management in the Ubiquitous Software Development

The continuous technical advances have lead to the proliferation of very small and very cheap microprocessors, equipped with sensors and capacity of wireless communication. The information processing is becoming ubiquitous and it is being impregnated in all type of objects. In this article the general delineations set out towards a methodology of securing of the quality of software ubiquitous based their main characteristics: centered in the user and highly interactive. Moreover, it considered to the usability as the quality characteristic of more relevant in the development of this type of highly interactive software systems.
