Report types
Category research
Structured analysis of a defined market segment covering category meaning, participants, differentiation, and evaluation criteria. Category research is the broadest output type Brightfield produces. It answers the foundational question: what is this market, who operates in it, how do participants differ from one another, and what does a responsible evaluation look like? Category research is not a product review. It establishes the shared frame of reference that all subsequent comparative and benchmark research within a category uses. A Brightfield category research output typically includes a category definition, a participant landscape overview, a documented set of differentiation dimensions, and a set of evaluation questions that reflect the real tradeoffs a decision-maker faces. It does not score or rank participants without a supporting benchmark or comparative analysis.
Market primer
A category-definition report explaining what a market segment covers, who it serves, what evaluation questions matter, and what proof a decision-maker should require before committing to a specific option. The market primer format is Brightfield's answer to the question that precedes any structured comparison: before evaluating specific options, what does a rigorous evaluator need to understand about the category itself? A market primer documents the category's scope boundaries (what is and is not included), the primary decision-maker profiles it addresses, the evidence standards appropriate for the category, and the failure modes that have been observed when evaluations go wrong. Market primers do not evaluate specific vendors or products. They are prerequisites for responsible comparative analysis. Brightfield publishes market primers as standalone outputs and also as the opening section of more complex benchmarks and comparative analyses.
Decision framework
A structured evaluation methodology that defines criteria, evidence standards, and scoring logic before assessing any specific option. The decision framework format is distinct from comparative analysis in a specific way: a framework is designed to be reusable. Where a comparative analysis applies defined criteria to a specific set of options at a specific point in time, a decision framework publishes the criteria themselves in a form that allows decision-makers to apply them to any option set, including options Brightfield has not assessed. A Brightfield decision framework documents: what criteria matter for the category question and why, how each criterion should be weighted relative to the others, what evidence is required to satisfy each criterion at each level of the scoring scale, and what common errors decision-makers make when evaluating options in this category. Decision frameworks are published with documented rationale for every criterion included and every criterion excluded from consideration.
Comparative analysis
A report placing two or more options side-by-side against documented criteria. Comparative analysis is the most directly actionable output format Brightfield produces. It answers the question: given these specific options and these specific criteria, how do they differ in ways that matter to the decision? A Brightfield comparative analysis begins with criteria documentation: the evaluation dimensions are defined and justified before any option is assessed. Then each option is assessed against each dimension using available evidence, with source notes indicating what evidence type informed each assessment. Gaps in evidence are documented as evidence gaps rather than treated as neutral. Comparative analysis outputs include a summary comparison, dimension-by-dimension assessments, documented limitations, source notes, and a commercial disclosure. They do not recommend a specific option unless there is a documented analytical basis for the recommendation that is visible in the criteria scoring.
Research primer
Brightfield's term for a category-definition report addressing what a segment covers, who it serves, what evaluation questions are relevant, and what proof standards apply. The term "research primer" is used in Brightfield publications rather than "buyer guide" because the audience for these outputs extends beyond purchasing decisions to include strategic analysis, market mapping, and policy evaluation. A research primer is not a purchase checklist. It is a structured orientation document that establishes the vocabulary, scope, and evidence standards that should govern any engagement with the category. Research primers are referenced in comparative analyses and benchmarks as the source of the criteria framework applied in those outputs.
Evidence concepts
Documented fact
A claim directly supported by Class 1 through Class 5 evidence from sources independent of the claiming organization. The documented fact is the most citable element of any Brightfield research output because it is the claim type that can be traced to a specific, external, verifiable source. In a Brightfield report, documented facts are typically labeled with a source note indicating which evidence class supported the claim. Not all research outputs contain documented facts about every dimension assessed. Where a dimension cannot be supported by Class 1 through Class 5 evidence, it is either documented as an evidence gap or assessed under editorial interpretation (Class 7), with that label clearly applied. Decision-makers citing Brightfield research in procurement or policy documents should limit their citations to documented facts and should reference the applicable source note.
Evidence gap
A question that the research cannot answer from available public sources, disclosed explicitly as a limitation of the output. Evidence gaps are not neutral omissions. They indicate that a dimension of evaluation that is relevant to the category question could not be assessed because sufficient public evidence was unavailable at the time the research was conducted. In a Brightfield output, an evidence gap is documented specifically: the question that could not be answered is stated, the evidence type that would be required to answer it is described, and the practical significance of the gap to the decision is assessed. Evidence gaps may resolve over time if new public documentation becomes available, if a correction or submission is received that addresses the gap, or if the covered organization publishes materials that address the missing dimension. When an evidence gap resolves, the publication date and the nature of the resolution are recorded.
Category risk
A specific condition identified in research that creates evaluation risk for a decision-maker operating in the category. Category risks are distinct from evidence gaps in that they are documented findings, not absences of information. A category risk is something Brightfield's research has identified as a consistent source of poor outcomes in the category: vendor lock-in clauses that are buried in contracts and rarely disclosed in marketing, pricing models that change materially at renewal without public notice, capability claims that are accurate in controlled conditions but do not hold at operational scale. Category risks are documented in research primers and carried forward into comparative analyses as required evaluation dimensions. They represent the analytical judgment of the Brightfield editorial team and are labeled as such.
Evidence classes
The seven evidence classes define how Brightfield treats and labels different source types. All research inputs are assigned to exactly one class.
Direct documentation (Class 1)
Official materials published by the assessed organization itself, including its own product pages, documentation, specification sheets, published contracts, pricing pages, and official communications. Class 1 evidence carries the highest interpretive weight for claims about the organization's own attributes — what it says it does, what it publishes as its pricing model, what it states as its capabilities. It does not carry high interpretive weight for claims about independent performance, market standing, or outcomes experienced by customers, because those claims cannot be independently confirmed through the organization's own materials. Brightfield treats Class 1 evidence as authoritative for what an organization asserts and documents about itself, while explicitly noting that self-reported claims without independent corroboration are labeled as organizational claims rather than documented facts.
Independent review signal (Class 2)
Aggregated patterns from third-party review platforms, assessed at the aggregate level rather than the individual review level. Class 2 evidence is used to identify patterns in user experience that recur across multiple independent accounts, not to cite individual reviews as proof of specific capabilities or failures. A single review on a third-party platform is not Class 2 evidence. An observable pattern across hundreds of reviews, where the same experience or limitation is documented independently by multiple reviewers in similar organizational contexts, begins to carry interpretive weight as Class 2 evidence. Brightfield does not name individual reviewers or quote individual reviews. It documents patterns — frequency of a reported issue, distribution of reported satisfaction levels, patterns in what reviewers identify as strengths and weaknesses — and notes the platform and the time period from which the pattern was observed.
Editorial interpretation (Class 7)
Conclusions drawn by the Brightfield research team based on available evidence from other classes, always labeled explicitly as interpretation and never presented as documented fact. Class 7 is the final evidence class and carries the lowest evidentiary weight. It is the class used when the research team has formed a view based on the totality of available evidence but cannot trace that view to a single documentable source. Class 7 interpretations are required in almost every Brightfield research output because evidence gaps are common in market research, and the editorial team's responsibility includes forming views, not just reporting facts. The discipline is in the labeling. Every conclusion that rests primarily on editorial judgment rather than documented evidence from Classes 1 through 6 is identified as editorial interpretation in the output. It is cited as "editorial assessment" or "research team interpretation," never as a finding of the same evidentiary weight as a documented fact.
Output elements
Correction
A factual change to a published report based on contrary evidence that meets Brightfield's evidentiary standard, reflected in the output's update timestamp and recorded in the changelog. A correction is distinct from an update in that it addresses a specific factual error in the original publication — a claim that was incorrect based on evidence that was available or that subsequently became available. Updates address information that was accurate when published but has since changed. Corrections are documented with specificity: the original claim, the basis on which it was found to be incorrect, the corrected claim, and the source of the correcting evidence. Brightfield does not silently alter published outputs. Every correction is disclosed on the relevant page and recorded in the site changelog. Corrections submitted through the evidence pathway are reviewed by the editorial desk before acceptance. A submission does not guarantee a correction; the submitted evidence must meet the applicable evidence class standard for the claim being challenged.
Source note
A disclosure in a published report identifying which sources informed which conclusions, enabling readers to trace the evidentiary basis for specific claims. Source notes are a structural element of every Brightfield research output, not optional attribution. They serve two purposes: accountability and citability. The accountability purpose is to allow any reader to examine the basis for a conclusion and form their own view of whether the evidence supports it. The citability purpose is to enable secondary citation — if a reader wants to cite a specific Brightfield finding in their own work, the source note allows them to trace the original source and verify it independently. Source notes in Brightfield publications identify the evidence class, the general source type, and, where the source is publicly accessible, a reference sufficient for independent verification.
Limitation
A constraint on the scope, currency, or completeness of a research output, documented on every Brightfield page as a structural requirement. Limitations are not admissions of failure. They are the evidence of rigorous research practice. A research output that claims no limitations is not a more complete output — it is one that has not done the work of identifying where its evidence is incomplete, where its criteria may not apply to every reader's context, or where the elapsed time since publication may have reduced the accuracy of specific findings. Brightfield requires a documented limitations section in every research output. The limitations section addresses at minimum: the evidence that was unavailable, the scope boundaries that exclude specific use cases or organizational contexts, the currency risk (when the research was conducted and what categories of change could affect its conclusions), and any constraints imposed by the editorial assessment process itself.
Process terms
Evidence class
One of seven classification levels applied to every research input collected during a Brightfield research process, based on the source type and the proof weight that type of source can carry for different categories of claims. Evidence classes are assigned during the research collection phase and recorded in the research file. They govern how inputs are labeled in published outputs and what weight they are given in criteria scoring. The seven classes are: Class 1, direct documentation from the assessed organization; Class 2, independent review signals from aggregated third-party platforms; Class 3, market and analyst references from independent sources; Class 4, community and practitioner discussion from public forums and professional communities; Class 5, search and market signals derived from publicly observable market behavior; Class 6, submitted evidence from organizations or interested parties who disclose their relationship to the subject; and Class 7, editorial analysis and interpretation by the Brightfield research team. Classes 1 through 5 are independent of Brightfield; Classes 6 and 7 are generated within the Brightfield process.
Additional terms
Coverage initiation
The formal decision to begin research on a new category, documented with a stated research question, a preliminary evidence landscape assessment, and a criteria design brief. Coverage initiation is not the same as publication. A category may be in coverage initiation for weeks or months before a first research output is published, as the evidence landscape is mapped and criteria are designed. Coverage initiation criteria require demonstrable market demand, available public evidence, meaningful evaluation complexity, and a defensible research question. A category that meets all four criteria is eligible for coverage initiation. Coverage is not guaranteed to result in a published output if the evidence landscape assessment finds insufficient public evidence to support the research question.
Proof standard
The minimum evidentiary requirement for a claim at a given level of the scoring scale in a Brightfield criteria assessment. Proof standards are defined per-criterion in a research output and specify what evidence class and what volume of evidence is sufficient to support an assessment at each level. A proof standard of Class 1 evidence plus independent corroboration means that a claim must be documented in official organizational materials and confirmed by at least one independent source of Class 2 or higher. Proof standards vary by criterion because different claims require different types of evidence. A pricing model claim requires Class 1 evidence. A user satisfaction claim requires Class 2 or Class 4 evidence with documented patterns. An implementation complexity claim may require Class 4 community evidence or Class 7 editorial assessment based on aggregate signals. Proof standards are published as part of the decision framework for each research area.
Currency risk
The risk that specific findings in a published research output have become inaccurate due to changes in the assessed subject, the market, or the evidence landscape since the research was conducted. Currency risk is documented in the limitations section of every Brightfield publication with a specific assessment: which findings are most likely to become outdated quickly, what categories of change would affect those findings, and when the output is scheduled for review. High-currency-risk findings are those that depend on pricing information (which changes frequently), product capability claims (which evolve with software releases), or market positioning (which shifts as competitive dynamics change). Low-currency-risk findings include structural category definitions, evidence class assessments of historical documentation, and criteria frameworks that are based on principles rather than current product states.
Scope boundary
An explicit statement of what is included in and excluded from a Brightfield research output, published as part of the output's methodology documentation. Scope boundaries prevent misapplication of research findings by readers whose context differs from the context the research addressed. A scope boundary might specify the organizational size range the research applies to, the geographic markets covered, the use cases evaluated, or the subset of available options assessed. Scope boundaries are not limitations in the negative sense — they are the specification of what the research is designed to answer. A reader operating outside the stated scope boundaries should not apply the research's conclusions to their context without considering whether the criteria and evidence apply to their situation.
Research question
The specific, answerable question that a Brightfield research output is designed to address, documented at the time of coverage initiation and carried through to the published output. The research question disciplines the research process: it determines which evidence is relevant, which criteria are appropriate, and which scope boundaries are necessary. Research outputs that lack a stated research question tend to become descriptive rather than evaluative — they describe what exists in a market without producing the analysis that enables decision-making. Brightfield's research questions are formulated to be evaluative rather than descriptive. They ask "which approaches best serve this decision-maker profile and why" rather than "what options exist in this category." The stated research question is published at the top of each research output so readers can assess whether the question matches the decision they are trying to make.
Criteria design
The process of defining evaluation dimensions, their relative weights, and their proof standards before any specific option is assessed. Criteria design is the methodological step that separates structured research from advocacy. When criteria are defined before options are assessed, the assessment is disciplined by a framework that was not built to produce a predetermined conclusion. When criteria are defined after options are reviewed — or adjusted to favor options already known to the researcher — the output is advocacy dressed as research. Brightfield's criteria design process begins with the research question, derives the dimensions that are relevant to answering that question, establishes the weight each dimension carries relative to the decision-maker's priorities, and documents the proof standard required at each scoring level. Criteria design documents are retained as part of the research file and are available for editorial review.
Limitation: This glossary defines terms as used in Brightfield Research publications as of June 2026. Definitions may be updated when the methodology is revised. The applicable definition for any term in a specific report is the definition in effect at the date of that report's publication.
