It can connect information across systems—including documents and other unstructured material—but it is only one part of AI-ready data. Governance, permissions, quality, traceability, and workflow design still matter.
What role does a knowledge graph play in enterprise AI?
A knowledge graph represents entities—such as customers, contracts, products, assets, policies, and transactions—and the relationships among them. In McKinsey’s April 2026 discussion of agentic AI, it is one common way to implement a semantic layer between raw data and AI applications. The layer expresses business meaning in a machine-readable form that people can also understand.

Ontologies define the concepts and relationships used to describe business reality; a knowledge graph links data about real-world entities across systems into a connected network. Together, these can give AI applications shared definitions to work from. Without that common semantic foundation, agents may interpret the same data differently, a risk McKinsey says can grow as deployments scale. McKinsey’s agentic AI architecture guidance presents the graph as part of a larger system, not a substitute for it.

Enterprise information is more than rows in databases. It also includes source files and derived artifacts, such as extracted text, tables, images, metadata, sensitivity labels, and quality scores. McKinsey’s June 2026 data-readiness article argues that these representations should remain connected to their original sources and to one another.
#1 Best Overall
An enterprise graph can anchor documents and other unstructured artifacts to structured business entities. For example, a contract document might be linked to the customer, product, and transaction it concerns. Those links provide context that a searchable file repository alone may not: AI systems need to know what content refers to, how it relates to other information, and which version or source supports it. McKinsey also stresses making ownership, sensitivity, and permitted use explicit. Its data-readiness guidance treats connection, context, and traceability as parts of preparing enterprise data for AI.
What else must an AI-ready data foundation include?
A graph can help encode meaning and relationships, but it does not automatically make underlying information accurate, authorized, or fit for a workflow. McKinsey’s guidance describes complementary architecture and operating practices:
Rank #2
- Data quality and observability: establish how information is checked and monitored, including the quality of source data and derived artifacts.
- Governance and access control: define ownership, sensitivity, and permitted use; apply security controls by default and support fine-grained access where needed.
- Lineage and traceability: preserve links from derived content back to its source, so users and systems can understand where information came from.
- Shared definitions and ingestion: use consistent ways to bring data in and describe business concepts across applications.
- Reusable interfaces and execution controls: provide stable interfaces, monitoring, and a controlled layer for applications and agents.
- Workflow and operating-model change: redesign how work is done where AI is introduced; adding a graph alone does not accomplish that.
McKinsey also advocates a shared data foundation for analytics and AI rather than treating each application as a separate data island. These measures are interdependent: semantics help an AI system interpret information, while permissions, quality, lineage, and operational controls shape whether it can use that information appropriately. McKinsey’s architecture discussion describes these practices alongside the semantic layer.
How does this relate to agent architectures?
McKinsey describes two patterns for agentic systems. In one, a single agent uses multiple tools and data sources in sequence. In another, specialized agents collaborate, drawing on shared knowledge graphs and fine-grained data access. The second pattern makes the importance of consistent meaning and access controls particularly visible: collaboration depends on agents interpreting shared information coherently and being allowed to see only what they should.
Rank #3
Neither pattern makes the graph the whole architecture. The surrounding system still needs consistent ingestion, shared definitions, security, stable interfaces, monitoring, and controlled execution. The choice of agent pattern should follow the workflow and its requirements, rather than the assumption that a graph by itself determines the right design.
What does McKinsey’s bank example establish?
In a 2026 article on Central Europe’s AI opportunity, McKinsey describes a global universal bank using an enterprise agent factory to reengineer its software development life cycle. The effort centered on business rules, agent-ready artifacts, and a shared knowledge graph. The article’s example shows how a graph can sit within a broader effort to reshape a business workflow around agents.
Rank #4
The account does not name the bank or its graph technology, identify an implementation partner, or quantify results for the graph. It therefore supports the architectural point that a shared graph was part of this initiative—not a claim about a particular vendor, measured benefit, or independently verified outcome.
How should an enterprise assess this approach?
McKinsey’s material does not compare graph platforms. For an implementation, the practical questions are whether the proposed foundation supports the target workflow and the surrounding disciplines—not simply whether it can store relationships.
Best Value
- Are business concepts and relationships defined consistently enough for people and AI applications to use?
- Can the design connect structured records with relevant unstructured artifacts across systems while retaining source links and version context?
- Are ownership, sensitivity, permissions, and permitted uses represented and enforced?
- Can teams observe data quality and trace information from an AI output back to its source?
- Do interfaces allow governed reuse across the intended workflow?
- Can the organization support the required operating-model and workflow changes?
Older McKinsey architecture guidance offers useful context, but it is not evidence about the unnamed bank’s implementation. A 2021 article recommends designing around use cases and building a minimum viable data capability for each, then iterating. It describes graph databases as one kind of NoSQL technology that can represent relationships flexibly as information models change. That general advice does not identify the database used in the bank example. McKinsey’s 2021 architecture article and its older data-architecture guidance should be read as broad design context, not as a product recommendation.
