Study Notes

System Analysis process includes MBSE with functional, structural, and behavioral modeling, mathematical analysis, probabilistic and statistical modeling, simulation, and other modeling techniques.
Inputs and outputs for System Analysis process listed in Figure 2.46, described in Appendix E.
System Analysis process activities:
- Prepare for system analysis: establish strategy/approach, identify situation, stakeholders, scope, objectives, and level of fidelity. Choose analysis methods based on relevant drivers.
- Plan for necessary enabling systems or services.
- Ensure enabling system or service access and validity of assumptions.
- Ensure timely and trustworthy data and inputs.
- Establish criteria for trustworthiness of data.
- Review data and inputs for quality and validity.
Perform system analysis: execute analysis using selected methods, perform uncertainty and sensitivity analysis, perform quality and validity check, interpret results, and capture results in a report.
Manage system analysis: establish and sustain traceability, give CM needed information items, work products, or other artifacts.
Model limitations: models can't simulate all system behavior, parameters and data inputs must be part of the operation field, models evolve during the project, results are given in modeling context.
Recommended to use several types of models to compare results and consider different system characteristics or properties.
SE processes leverage different dimensions of system analysis: Business or Mission Analysis for effectiveness, feasibility, costs, risk preferences, and value preferences; Stakeholder Needs and Requirements Definition and System Requirements Definition for conflicts among requirements and technical risks.
