This paper approaches the issue of performance in the context generated by complex computer applications development. The concept of complex computer application is formalized. Categories of complex applications are listed and individualized. Mobile applications and the devices they were intended for are defined in correlation with complex applications standards. Citizen oriented applications are introduced and presented as problem solving and solution providing entities. The concept of innovation is described as part of complex computer application. Circumstances that trigger innovation are exemplified by offering particular demonstrations. The technologies used to develop innovative applications are outlined. Security is depicted as a fundamental requirement for performance. The process of securing computer systems is formalized into the concept of security management. Methods of managing network security by imposing security policies are enunciated. Access full paper here.
