IBM Software Group | Rational software 2 Agenda  A Systems Perspective  Challenges in Systems Engineering  How Model Based Systems Engineering Helps  Harmony – A Model-Based Systems Engineering Approach

IBM Software Group | Rational software 3 Systems Engineering  Systems engineering  Entire lifecycle  Defines / refines requirements  The holistic view  Overall architecture  Interplay between components

IBM Software Group | Rational software 4 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.  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.

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

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

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

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

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