Developing software costs money. Barry Boehm, in his classic work on software engineering economics, based upon 20 years of empirical evidence, concludes that the performance of a project can be predicted according to the following equationPerformance@ ComplexityProcess * Team * ToolsWhere•PerformanceEffort or time•ComplexityVolume of human-generated code•ProcessMaturity of process and notation•TeamSkill set, experience, and motivation•ToolsSoftware process […]

A further complication is the fact that, for industrial-strength software, there are typically a large number of stakeholders who shape the development process, most of whom are completely unimpressed by the underlying technology for technologies sake. These stakeholders will bring to the table a multitude of hidden and not-so-hidden economic, strategic, and political agendas that […]

Consider the requirements for the avionics of a multi-engine aircraft, a cellular phone switching system, or an autonomous robot. The raw functionality of such systems is difficult enough to comprehend, but now add all of the (often implicit) nonfunctional requirements such as usability, survivability, and adaptability, indeed, all of the forces that shape a system. […]

The difficulty of design, therefore, lies in choosing which design and architectural patterns we should use to best balance the technical, economical, business, political, and emotional forces that swirl around every software-intensive system. To put it in terms of the laws of software, this general problem of design is probably NP-complete: there likely exists some […]

the OMG Systems Modeling Language (OMG SysML) is a general-purpose modeling language for systems engineering applications.SysML supports the specification, analysis, design, verification and validation of a broad range of complex systems. These systems may include hardware, software, information, processes, personnel, and facilities.The origins of the SysML initiative can be traced to a strategic decision by […]
