Systems engineering techniques
1) Architecture modeling
2) Alternative analysis
Analysis of Alternatives (Alternate Analysis) (refer here)
a) How can we increase our benefits?
b) How can we realize the benefits sooner?
c) How can we lower our costs?
d) How can we push our costs to the future?
Magnitude effect & timing effect analysis (NPV, RPI & Payback)
Add the assumptions as well for sure.
3) Tradeoff analysis
Performance, Scalability, Extensibility, Agility, Maintainability, Feasibility
