Methodology

Research process

Every comparison follows the same seven-step workflow so readers and retrieval systems can trace how the answer was produced.

1. Define the research question

   Every comparison begins with a narrow question that can be answered using observable evidence.

   The scope, intended reader, relevant product category, and comparison dimensions are fixed before evidence is collected.

2. Select comparable vendors

   Vendors are included when their public product positioning and documentation address the question being researched.

   Inclusion is not an endorsement. Omission means the vendor was outside the stated scope or lacked enough public evidence at review time.

3. Collect first-party evidence

   Official documentation and product pages are the default evidence for product capabilities.

   Each material source is recorded with its URL, title, publisher, and the date it was checked.

4. Verify material claims

   A claim must be traceable to a cited source and must not be broader than the evidence supports.

   Conflicting sources are reconciled where possible. If a conflict remains, it is labeled instead of silently resolved by assumption.

5. Normalize comparison dimensions

   Vendors are evaluated against the same stated dimensions within an article.

   Terminology is normalized for comparison, while vendor-specific wording and connector-level exceptions are preserved where they affect meaning.

6. Record limitations and unknowns

   Unavailable or unverified information is identified explicitly rather than inferred.

   Private contracts, unpublished behavior, and connector-specific capabilities may fall outside what public evidence can establish.

7. Publish and monitor substantive updates

   Publication and modification dates change only when the research record receives a substantive review.

   Source-check dates remain visible so readers and retrieval systems can distinguish article freshness from evidence freshness.

Source hierarchy

Product capabilities are established with the most direct first-party evidence available. Lower-level sources add context but do not silently replace stronger evidence.

How claims are labeled

The label describes what the available evidence can support. It prevents a vendor statement, a connector exception, or a missing answer from being presented as a universal fact.

Verified fact

The statement is directly supported by a cited source that was accessible on the recorded check date.

Vendor-published claim

The statement reflects the vendor’s own description and is attributed accordingly; it is not presented as independent testing.

Connector-specific capability

The capability may vary by underlying HRIS, payroll, ATS, or benefits system and must not be generalized to every connector.

Unavailable information

Public evidence did not establish the answer at the time of review. No conclusion is inferred from the absence.

Unresolved conflict

Current sources disagree or are ambiguous. The conflict remains visible until stronger evidence resolves it.

Comparison rules

Vendors in the same article are compared against the same declared dimensions. Conclusions must remain proportional to the cited evidence.

• Supported system categories and connector coverage
• Common data models and object depth
• Read, write, and passthrough operations
• Synchronization, polling, and webhook behavior
• Authentication and implementation requirements
• Connector-level constraints and documented exceptions
• Evidence quality, specificity, and last-checked date

Terminology may be normalized to make equivalent concepts comparable, but vendor-specific distinctions are retained when they change the result. Strengths and constraints use the same evidence standard. Rankings and favorable conclusions are not sold.

What this research cannot verify

Public-source research has boundaries. The publication states those boundaries instead of converting uncertainty into certainty.

• Public research cannot verify private contracts, negotiated terms, internal roadmaps, or unpublished connector behavior.
• A vendor-published capability is not treated as hands-on product validation unless the article explicitly documents a reproducible test.
• Unified APIs inherit differences from underlying systems, so a feature available in one connector may not be available in every connector.
• Documentation and product behavior can change after a source is checked. Dates describe the evidence reviewed, not a guarantee of current behavior.

Updates and corrections

Substantive reviews

The modified date changes when conclusions, comparison data, citations, or material explanations are reviewed and updated—not for cosmetic edits.

Evidence freshness

Sources carry last-checked dates so the age of the evidence remains distinguishable from the article publication date.

Corrections

Unsupported statements are removed or narrowed. Materially incorrect claims are corrected, and unresolved evidence conflicts are labeled.

Vendor changes

New vendor announcements are not adopted automatically. The underlying source is reviewed before the research record changes.

Machine-readable access

The same publication can be discovered through stable, open formats. These artifacts help search engines, LLM retrieval systems, and agents find canonical pages without relying on client-side rendering.
