Tactic: Parameter Space Construction

Orchestration Pattern

1. Spawn driver identification → scenario-driver-identification

   • Pass: research context, planning horizon, domain constraints
   • Receive: ranked list of 5-8 uncertainty drivers with descriptions

2. Validate driver set

   • Check: Are drivers independent? (no redundancy)
   • Check: Do drivers span PESTEL categories? (no blind spots)
   • Check: Are drivers at the right abstraction level? (not too broad, not too narrow)
   • If validation fails: re-spawn with refined instructions

3. Spawn parameter enumeration → parameter-enumeration

   • Pass: validated driver list, MECE requirement, value count guidance (2-4 per driver)
   • Receive: complete Zwicky Box (driver × value matrix)

4. Validate parameter space

   • Check: Are values mutually exclusive within each driver?
   • Check: Are values collectively exhaustive within each driver?
   • Check: Is the total configuration space manageable? (< 500 combinations)
   • If validation fails: re-spawn enumeration with tighter constraints

5. Compute space metrics

   • Total configurations: product of all value counts
   • Expected surviving configs after CCA: ~10-20% of total
   • Estimated downstream budget: configs × per-scenario cost

Quality Checks

• All drivers are genuinely uncertain (not predetermined)
• No driver is a subset or consequence of another
• Values within each driver are truly MECE
• Total space is computationally tractable for CCA
• Parameter space covers the planning horizon adequately

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP	When to use
parameter-enumeration	Enumerate possible values for each uncertainty driver using MECE principles
scenario-driver-identification	Identify key uncertainty drivers using PESTEL framework scanning
