Context
What needed to be decided?
The model begins with the real situation, the constraints and the question that required a direction.
Decision Models
Decisions should remain explainable after implementation.
Decision models connect context, alternatives, trade-offs and consequences. They preserve the reasoning behind important research, architecture and system choices.
A documented decision is easier to review, challenge and improve.
Model structure
Reasoning becomes useful when its parts remain visible.
Alternatives
Which paths were available?
Relevant alternatives remain visible so the final direction can be understood in relation to what was not chosen.
Decision
What was chosen and why?
The selected direction is connected to evidence, constraints, system boundaries and long-term maintainability.
Impact
What changes as a result?
The model records consequences for architecture, implementation, responsibility and future evolution.
Public value
Selected models can make complex system choices easier to understand.
Public decision models focus on choices that reveal a reusable principle, an architectural boundary or an important change in understanding.
Sensitive operational details remain outside the public layer, while the reasoning that benefits wider understanding can be shared.
