IBM Software Group | Rational software A Systems Perspective § The systems approach focuses on systems taken as a whole, not on the parts taken separately. § It assumes that some properties of systems can only be treated adequately by taking into account all facets of the system. 4 These system properties derive from the relationships between the parts of systems: how the parts interact and fit together. § A basic assumption of systems engineering is that optimization of individual components or subsystems will not in general lead to a optimum system. § Similarly, individual component behavior cannot be understood without considering the components’ role and interaction within the system as a whole. 4

IBM Software Group | Rational software Challenges of Systems Engineering (1) § Increased system complexity 4 Due to languages, technology, and global information flow capabilities. § Greater pace of change 4 Time required to deliver solutions is reduced. § Systems development has not kept pace with the demands to deliver more capability in less time 4 Using traditional methods, development teams often deliver late, or fail to deliver at all. 5

IBM Software Group | Rational software Challenges of Systems Engineering (2) § Increasingly system failures arises from the interactions among components. 4 High levels of interactive complexity is unmanageable using traditional techniques. 4 The drive toward tightly coupled systems is fueled by a desire for higher levels of efficiency and functionality. 4 Software allows us now to achieve these higher levels of coupling and interaction that were previously impossible with pure electromechanical devices. 6

IBM Software Group | Rational software How Model Based Systems Engineering Helps § Modeling helps to: 4 Manage complexity. 4 Simplify and abstract essential aspects of a system. § Increase understanding. 4 Enhance team communication. § Usable by engineers across multiple disciplines. § Common language promotes common understanding. 4 Reduce risk. § Model execution increases knowledge and reduces uncertainty and risk. 4 Provide traceability. § Models document what you have done. 4 Assess impact of change. 7

IBM Software Group | Rational software Benefits of Modeling § ‘Better’ Systems – identify ‘defects’ earlier. 4 Models may be verified and validated: § Statically – checking for consistency. § Dynamically – execution of models allows identification of missing, conflicting or overlapping requirements. § Increased productivity. 4 Automation of workflows. 4 Re-use of intellectual property. § Model Based Systems Engineering leads to a more robust design. 4 Reduced development time. 4 Fewer recalls. 8

IBM Software Group | Rational software Harmony – A Model Based Systems Engineering Workflow § Model-driven hybrid iterative workflow, supporting: 4 Top-down systems engineering ( Rational HARMONY SE ) 4 Incremental software engineering ( Rational HARMONY ESW) § Seamless transition from systems engineering to software engineering by using the Sys. ML as paradigm independent modeling language. 4(“Same language, different dialects”) 9
