Lesson 4: The Economics of Drift

The seven mismatches map directly to DORA metrics and measurable operational costs: this lesson provides the formula structure to quantify the architectural tax.

Each topic below covers a building block of this lesson. We recommend following them in sequence as each builds on the last.

Where the Money Leaks

Five cost categories with DORA metric mappings: failed deployments, rollback hours, release delays, audit risk, and developer burnout.

The Human Translator Tax

Why the Release Manager role exists, what it costs, and the formula including variable tables and sourced ranges.

The Trust Tax

How pipeline failures erode team confidence, generating slower cadence, more manual gates, and routing around the pipeline.

The Break-Even Calculation

The comparison structure and worked example for calculating when a purpose-built platform pays for itself.

The Formal Cost Model

The three formulas (Human Translator Tax, Deployment Loss, Compliance Overhead) with full variable tables, sourcing tiers, and documented assumptions.

DORA Metric Mapping

Maps all four DORA metrics to structural causes in the Git-Salesforce architecture, with tier benchmarks for each.

Sensitivity-Range Spreadsheet

Identifies which inputs drive the most cost model variance: where to measure precisely and where defaults are acceptable.
