The services paradigm: Who can you trust?

New technologies such as software as a service and service oriented architectures have emerged and are growing at a phenomenal rate. A new kind of physics using new approaches, both mathematical and nonmathematical is needed to help understand and communicate about complex systems and create trust. Engineers and scientists generally depend on comprehensive and universal mathematical equations that describe the physical properties and interactions of electromechanical, optical, hydro and thermodynamic, and other systems. Jeff Voas and Keith Miller have attempted to build models to manage trust expectations for processes and software. Their approaches incorporate one or more of the three system views of software including, processes, people, and products. A system must be reliable, fault tolerant, safe, secure, available, good in testability and maintainability in order to achieve trust within the software programmers.
