Reality-MUX - Iterative Planning When Everything Changes
A planning loop for software where nothing stays still. Reused from production operational design, translated to shipping code under distributed teams.
Every plan has a horizon. After that horizon, you are guessing.
Why linear roadmaps fail
Linear roadmaps assume stability. They say "Phase 1 in January, Phase 2 in March." Reality does not care. A dependency moves. A market changes. A teammate gets pulled onto an incident.
When the horizon is short, that is fine. When you are designing systems across months, it is not.
The Reality-MUX loop
Reality-MUX is a planning loop:
- Define the current state clearly.
- Define the ideal state with testable outcomes.
- List the smallest set of changes that reduce the distance.
- Execute one slice.
- Recompute the current state.
It is iterative by default. There is no failure state, only a missing cycle.
Operational behavior
- Small slices reduce risk.
- Explicit current-state definitions prevent drift.
- Completed milestones are durable evidence.
- Definitions of done are public.
Why this matters for shipping
Self-evaluating goal loops prevent the comment section pattern: lots of discussion, missing artifacts. If you are not adding files, you are not executing.
The branch between planning and execution is small. The branch between a shipped plan and an academic plan is huge.
The answer
Iterate. Ship. Evaluate. Repeat.
