# Observability, quality, cost and operations

Technical success rates, product quality and customer value are measured separately and then linked through stable identifiers; only by seeing cost, quality, risk and real acceptance can a platform be run for the long term.

## What this page covers

This is MYRILUM's target architecture. It does not mean everything on the map is live; whether a capability can be used today is stated in “Current availability”.

What cannot be seen cannot be managed. This page states principles only; implementation details are not published.

<a id="three-measures"></a>

## Three kinds of “good”, measured apart

A successful call does not mean the research is right, and more deliveries do not mean users got value or the business works. Technical operation, product quality and customer value are measured separately and then linked through stable identifiers such as tenant, project, task, run and product version.

<a id="effective-delivery"></a>

## Effective delivery is the core measure

The core measure is effective delivery: a delivery made within authorization and budget that passes acceptance as agreed. Around it sit quality and experience (revisions, refunds, complaints, first-time acceptance, retention), the cost of each effective delivery, and constraint measures such as permission incidents, data leaks, duplicate charges and supplier concentration.

<a id="targets-need-samples"></a>

## Targets are promised only with samples

Availability, quality, recovery and cost targets are promised only after their samples, measurement windows and constraints are stated; no number is given without a basis.

<a id="respond"></a>

## When something goes wrong: contain, recover, review

Alerts are graded by impact, scope and urgency and given an owner. First contain the impact — pause new tasks, switch off the failing capability or move to an approved alternative — then repair, roll back, compensate and reconcile, and finally review the cause and verify the improvement.

<a id="scoped-visibility"></a>

## Observability data is need-to-know too

Customers see progress, operations sees quality, engineering sees failures. Staff dashboards show only what is needed, and customer data, logs and debugging records are not open to everyone. Every improvement is a hypothesis: evaluated before release, observed after it, and rolled back or redesigned if it has side effects.
