Implementation Pitfalls and Practitioner Complaints: Teamcenter Requirements Management

What's genuinely documented vs. what's generic

Public, specific-to-Requirements-Management pitfall documentation is thin — most of what surfaces in search is generic Teamcenter PLM complaint content (G2 reviews) rather than RM-specific troubleshooting threads. This mirrors the Program Planning/Schedule Manager research pass's finding that Siemens' own community forums (community.sw.siemens.com, community.plm.automation.siemens.com) return blocked/error pages to automated fetch, so admin-forum-level RM troubleshooting content (the kind found for Schedule Manager notification issues in this KB) could not be located or verified for Requirements Management specifically.

G2 review-derived complaints (general Teamcenter, not RM-specific, but recurring themes)

• Steep learning curve, repeatedly cited as the top complaint category — reviewers note that everyday tasks require multiple steps, and infrequent users in particular struggle to retain the workflow.
• Feature sprawl: Teamcenter "has many features, but not all useful or easy to understand for every situation" — i.e., breadth of capability comes at the cost of discoverability, a complaint that would plausibly extend to RM given how many adjacent capabilities (Systems Architect, Product Requirements, Requirements Integrator, Copilot AI checks) are bundled under "Requirements Management/Systems Engineering."
• Clunky menus/workflows for first-time users, and slow performance, especially cited around assembly loads (a PLM-wide performance complaint, not confirmed as RM-specific, but relevant if requirements are heavily cross-linked to large product structures).
• A separate migration-context comment (not attributed to a specific named source with full confidence) notes that a "key challenge was convincing end users because they were still thinking about files" when migrating legacy, file-based requirements/document processes into a centralized Teamcenter backbone — this is a soft, paraphrased finding rather than a directly quotable one, and is included here as a plausible/commonly-cited change-management pitfall rather than a hard data point.

Documented pitfall pattern: check-out/lock contention

Teamcenter's standard object locking model (explicit check-out via menu command, or implicit check-out when a dataset is opened by double-click) applies to requirements documents the same as any other managed object. This is standard PLM check-out/check-in behavior, not a bug, but it is a real practical friction point specifically for Word/Excel round-trip authoring (see rm-word-excel-roundtrip-and-reqif.md): if two authors need to work on the same requirements document concurrently, standard Teamcenter locking will block the second author until the first checks in — no public source found describes a merge-and-reconcile capability for concurrent Word/Excel requirement edits, meaning organizations doing distributed, multi-author requirements authoring likely need to plan around serialized check-out rather than assume real-time concurrent editing (unlike, e.g., a cloud document co-editing model).

Migration from legacy tools (DOORS, spreadsheets) as an implicit pitfall

Multiple sources (Siemens' own Requirements Integrator material, PROLIM/PLM Nordic partner content) frame the "requirements currently live in isolated spreadsheets or legacy DOORS installations" state as the default starting point most Teamcenter RM adoptions are migrating away from — implying that migration effort (mapping legacy attributes/templates into Teamcenter's data model, retraining authors off familiar standalone tools) is a real, if under-published, part of most real deployments. No specific migration-cost or migration-duration case study was found to substantiate this quantitatively.

Honest gap

No independently-verified, RM-specific "lessons learned" postmortem or implementation retrospective (the kind of specific admin-forum thread found for Schedule Manager notification troubleshooting in this KB's sibling files) was located for Teamcenter Requirements Management in this research pass. The pitfalls documented above are either (a) general Teamcenter PLM complaints reasonably inferable to extend to the RM module, or (b) structural/architectural implications (locking model, migration burden) inferred from how the product is described to work, not observed practitioner incident reports.
