Definition
The Systemic Problem Taxonomy categorizes all system-related investigations into three fundamental types based on which variables are given and which must be observed: Analysis, Design, and Control.
Why It Matters
Correctly classifying a problem is 90% of the solution. Using a taxonomy prevents ‘tool-to-problem’ mismatch, ensuring that you don’t apply a simple linear fix to a wicked, systemic issue that requires a multi-pronged, structural intervention.
Core Concepts
The taxonomy is defined by the relationship between Inputs, States (Internal mechanics/Transition functions), and Outputs:
| Problem Type | Given (Knowns) | To Observe (Unknowns) |
|---|---|---|
| Analysis | Inputs, States | Outputs |
| Design | Inputs, Outputs | States (The system itself) |
| Control | States, Outputs | Inputs |
- Analysis: Understanding how an existing system responds to various stimuli.
- Design: Creating/engineering a new system that transforms specific inputs into desired outputs.
- Control: Determining the necessary interventions (inputs) to ensure an existing system produces a specific result.
