# Depthics > Depthics is an independent practice offering one service: a Business Architecture Review for a recurring business problem, transition or decision. Depthics examines the connected parts of a business that may affect the question, including decisions, responsibilities, information, workflows and systems. The public site explains the service, method, professional boundaries and legal limits. It does not accept confidential evidence or create an engagement by browsing. The primary public next step is to [Discuss the problem](https://depthics.com/contact) by email with a short, non-confidential description. The separate Client access system is protected and is not a public content source. ## Core public pages - [Depthics home](https://depthics.com/): The public overview of the practice and its Business Architecture Review. - [Business Architecture Review](https://depthics.com/business-architecture-review): The service, appropriate use, scope, method, deliverable and fit boundaries. - [About the Depthics Practice](https://depthics.com/about): The practice point of view, founder-approved proof and operating facts. - [Business Architecture Method](https://depthics.com/method): How the Review moves from a business question through evidence, findings and next steps. - [Professional Boundaries](https://depthics.com/professional-boundaries): What the practice may examine, what it does not provide and when work is referred, narrowed, paused or stopped. - [Discuss the problem](https://depthics.com/contact): The direct email path and the information to include without sending confidential material. ## Public legal and security pages - [Legal information](https://depthics.com/legal): The public legal page index and operating boundary. - [Privacy notice](https://depthics.com/legal/privacy): Information handled by the public site and direct email path. - [Website terms](https://depthics.com/legal/terms): Terms for using the public website. - [Cookies](https://depthics.com/legal/cookies): Current cookie and browser-storage statement. - [Accessibility statement](https://depthics.com/legal/accessibility): Accessibility support and known limits of the current site. - [Legal Notice](https://depthics.com/legal/imprint): Operator identity and public service boundary. - [Data processing agreement](https://depthics.com/legal/dpa): The public boundary for engagement-specific Data Processing Agreements. - [Security](https://depthics.com/security): The public security boundary and reporting contact. ## Machine-readable resources - [XML sitemap](https://depthics.com/sitemap.xml): Canonical public URLs for search crawlers. - [Robots policy](https://depthics.com/robots.txt): Crawler access policy and sitemap location.
