FDE
Forward Deployed Engineer
A field-facing role spanning diagnosis, engineering, adoption and outcome validation; scope varies across organizations.
Learn in context / W01 ↗CONCEPT ATLAS / 30
Clear concepts.
A shared working language.
Concise definitions, real boundaries and module links. Knowing when not to use a technology matters as much as naming it.
Agent
Agent
A system where a model selects steps and tools from goals and feedback; autonomy is bounded by evidence and authority.
Learn in context / W05 ↗Workflow
Workflow
A predefined execution path that may include model calls; it is not necessarily an autonomous agent.
Learn in context / W05 ↗Skill
Reusable skill
A reusable task specification with inputs, method, tools, acceptance and failure handling. Preserve provenance and licensing.
Learn in context / W11 ↗Ontology
业务本体 / Business ontology
Explicit objects, relationships and actions that align business meaning with operations.
Learn in context / W05 ↗Entity resolution
实体消歧
Deciding whether records refer to the same entity while controlling false and missed merges.
Learn in context / W05 ↗Semantic layer
语义层
A governed definition of metrics, dimensions and calculations, distinct from document retrieval.
Learn in context / W03 ↗RAG
Retrieval-augmented generation
Generate with retrieved material; retrieval does not ensure applicability or answer correctness.
Learn in context / W05 ↗MCP
Model Context Protocol
A protocol connecting AI applications to tools and context, not automatic authorization or semantics.
Learn in context / W05 ↗Tool contract
工具契约
A testable definition of inputs, outputs, authority, bounds, errors, idempotency and outcome states.
Learn in context / W08 ↗Fit / Gap
适配与缺口
Separate standard support, configuration, adaptation, product gaps and unsupported needs.
Learn in context / W01 ↗SOW
Statement of Work
A scope and deliverables statement with responsibilities, timing and acceptance; contracts need professional review.
Learn in context / W03 ↗POC / Pilot
概念验证 / 试点
A POC tests feasibility; a pilot tests bounded real use, adoption and value. Neither automatically proves production readiness.
Learn in context / W04 ↗MVA
Minimum viable architecture
A teaching term for the minimal data, tool, model and logging architecture needed for one working slice.
Learn in context / W04 ↗Evals
评估
Measure capability and failure modes through tasks, grading and outcome evidence, not chat impressions.
Learn in context / W07 ↗Golden set
黄金样本
Domain-reviewed representative tasks and expected behavior, maintained with version control.
Learn in context / W07 ↗Holdout
保留测试集
A test set excluded from tuning to check generalization; repeated tuning against it defeats the purpose.
Learn in context / W07 ↗Regression
回归测试
Check preservation of important capabilities, separating safety gates from general quality.
Learn in context / W07 ↗Guardrail
护栏
A combination of input, tool and output safeguards; a prompt alone is not a security boundary.
Learn in context / W09 ↗Prompt injection
提示注入
Untrusted content attempts to redirect instructions or exceed authority, including through retrieved documents.
Learn in context / W09 ↗Idempotency
幂等
Repeating the same valid request does not duplicate effects; key/payload conflicts require explicit handling.
Learn in context / W08 ↗Compensation
业务补偿
A corrective action for effects that cannot simply be rolled back; distinct from transaction rollback.
Learn in context / W08 ↗Trace
执行追踪
Correlated model, tool and outcome events for a task; does not require storing private internal reasoning.
Learn in context / W09 ↗SLO / SLA
服务目标 / 服务约定
SLOs define measurable objectives; SLAs formalize service commitments with scope, windows and responsibilities.
Learn in context / W09 ↗OLA
Operational Level Agreement
Commonly an internal Operational Level Agreement in IT service management, not a universal Outcome-Level Agreement.
Learn in context / W10 ↗DiD
Difference-in-differences
Treatment change minus comparison change, with identification assumptions required for causal interpretation.
Learn in context / W10 ↗Percentage point
百分点
The absolute difference between rates: 20% to 24% is four points and a 20% relative increase.
Learn in context / W10 ↗RaaS
Result-as-a-Service
An outcome-linked commercial model requiring attribution, risk and responsibility definitions.
Learn in context / W10 ↗Adoption
采用
Actual workflow use, distinguishing trial, sustained use, edited acceptance and execution.
Learn in context / W08 ↗NRR
Net revenue retention
Revenue retained in an existing customer cohort after expansion, contraction and churn, excluding new customers.
Learn in context / W11 ↗No matching concepts.
Technical definitions link to official documentation in their modules. Commercial and operating definitions are teaching explanations; actual organizational and contractual definitions prevail.
