Decision Making and Systems Engineering

Systems engineering is an interdisiplinary approach to enable the successful realization of systems. Learning the systems engineering process is not a complex task. The tough part of systems engineering is making decisions related to trade-off studies, and balancing among the different requirements, which could at many times be orthogonal and conflicting.

An effective systems engineer is one who can provide insights and advice related to technical decisions. This would occur as follows,

1. Ensuring requirements are clear, well understood, correctly prioritized, and motivation well understood
2. Modeling and simulation and developing what-if scenarios
3. Conducting trade studies and parametric analysis
4. Clearly defining interfaces and boundaries, their requirements and impacts
5. Comprehensive risk management and optimum risk handling
6. Justify changes to requirements, design, scope, resource demands and technology
7. System optimization to develop a best solution in situation where multiple aspects of a system can be optimized
8. clearly defining dependencies, integration constraints and alternatives

The value of the system engineer is not only implementing the systems engineering capability pattern, but also ensuring that true value is being realized through the implementation of the SE capability patten. This true value will be achieved through solid decision-making.
