All markup is planned only and is added when approved pages are published. [PENDING — client approval; no live changes] ## 1. Entity and topical authority EVOCEAN is described consistently as one entity: an engineering and IT consultancy (CH/DE) that puts tools to work — IBM ELM / DOORS Next, Rhapsody, Perforce P4 / P4 Plan — plus systems engineering and AI for engineering. Topic clusters, each with one hub and supporting pages linked both ways: | Cluster | Hub | Supporting topics | |---|---|---| | Requirements & ELM | /services/ibm-elm | DOORS Next evaluation, DOORS Classic migration, ReqIF, requirements engineering | | Modelling & MBSE | /training/rhapsody | Systems engineering, model-driven development, Rhapsody Model Manager | | Versioning & planning | /products/perforce-p4 | P4 Plan (Jira alternative), configuration management | | AI for engineering | /services/strategic-ai | EVOLVIA AI test engineer, sovereign AI, computer vision | | Topic sites | corporate entries | Life Sciences (quality leaders), Worktransformation (HR), Digital Adoption, ReqIF — each its own site, no cross-domain hreflang | Rules: the same company facts on every page (name, locations, founding 2006); answer-first paragraphs under each H2; product and trademark names kept untranslated; no invented customer names, numbers or certifications — proof stays [PLACEHOLDER] until approved. ## 2.

Product schema carries name, brand (IBM, Perforce, CodeSecure, Newired) and description only — no prices or ratings. Course schema on Rhapsody pages: 3-day baseline, on-site max 10 / online max 8, English, German, French; enquiry-led, no fixed dates. ## 3.
