Application Estate Complexity Assessment

Evaluating whether your organization requires an Operational State Control Plane—or whether existing configuration mechanisms and feature flags remain sufficient—is an architectural decision that should be grounded in empirical observation rather than platform dogma.

Participating Surfaces & Capabilities

Click any card to select or deselect client applications and user-facing capabilities that must coordinate during degraded service or maintenance.

1. Client Surfaces Inventory (S)

3 Selected

Which client applications interact directly with users and need coordinated runtime state?

2. Critical Capabilities Inventory (C)

5 Selected

Discrete capabilities whose impairment requires coordinated graceful degradation or status updates.

Selected: 3 surfaces, 5 capabilities

Architectural Evaluation Context

Methodology and decision boundaries adapted from Appendix D (Engineering Economics) and Appendix F (Evaluation Worksheet).

How is the Estate Complexity Score (𝒦) calculated?

The formula 𝒦 = S × C × T_teams × (1 / Ā_sync) models the physical coordination surface of your estate. It scales with unique client surfaces (S), critical capabilities (C), participating engineering teams (T), and inversely with deployment synchronization (Ā_sync).

Why does RuntimeHQ advise Zone 1 teams NOT to adopt an OSCP?

We believe in architectural honesty. For a monolithic application or tightly coupled single-surface system with unified deployments and low operational friction, introducing a dedicated control plane layer adds unnecessary architectural footprint. Local environment variables and established release toggles remain sufficient.

What is the difference between Feature Flags and an OSCP?

Feature flag platforms excel at progressive software delivery, A/B experimentation, and percentage rollouts. An Operational State Control Plane governs runtime operational conditions (outages, degraded modes, maintenance) with deterministic severity hierarchies, multi-surface distribution, and durable audit logs.

Is my assessment data stored or sent to remote servers?

No. This audit runs 100% client-side in your browser. All parameters are calculated locally in memory and optionally persisted in your URL query string so you can share your results directly with your team.
