The Complexity Debt
Why Modern IT Keeps Getting Harder to Operate
A working manuscript about the work every apparently reasonable layer adds: a tool, control, integration, exception or automation. It follows systems whose individual parts can each be defended while their relationships cannot be explained during a change window or incident. Rather than reducing complexity to a complaint about too many components, the book asks what future attention, recovery knowledge and judgment a decision requires before it enters production.
THE BOOK’S QUESTION
A system can improve in every visible part and become harder to operate as a whole.

BEFORE YOU OPEN THE BOOK
Three ways into the volume.
These are neither promises nor chapter summaries. They name the operational questions the book stays with.
Inventory is not an operating model
Why a list of services and owners is insufficient if an on-call operator cannot see the transaction, the condition and the smallest safe move.
Automation must preserve the question
How a useful action or runbook becomes dangerous when its conditions, stop point and route back have disappeared from view.
SELECTED PAGES
A reading sample, at your pace.
These seven pages are selected across the volume. They follow a question, a situation, a distinction and the trace of a decision — without compressing the book into a summary.
THRESHOLD
The system that no one can explain
The opening proposition: systems become impossible one reasonable decision at a time.
CONTINUE THE CORPUS
Map the service that users actually experience.
The Observability dossier makes the gap between component health and the working transaction visible.
Seven pages selected from the current reading proof, which explicitly contains the introduction and the drafted sequence through Chapter 18.
