Layer 5
Compounding memory
A durable record of decisions and lessons. Each engagement starts further along than the last.
What this layer is
The fifth layer is what makes the methodology improve over time rather than reset every session. Decisions are written down. Lessons are captured. The next piece of work begins where the last one ended.
Consultants do not accumulate knowledge this way; their engagements end and the next client starts from zero. The Filix methodology is designed so that every engagement makes the next one cheaper, faster, and safer.
Failure mode it prevents
Session amnesia. Lessons that vanish when the engineer rotates off or the consultant rolls off.
What happens next
A focused walk through the methodology.
A working session covering all five layers and how they would map to the systems you actually have to modernise.
