At a Glance

A 2026 target operating model aligning AI, data, architecture, and controls helps banks integrate innovation with governance. Clear ownership, modern platforms, and embedded risk management enable scalable AI adoption while maintaining regulatory compliance and operational resilience.

Why the target operating model has become the execution contract

In 2026, banking transformation has shifted from experimental modernization to governed intelligence. The difference is scale and accountability: banks are moving beyond isolated pilots toward enterprise blueprints that can industrialize agentic AI, support real-time data foundations, and deliver measurable ROI without eroding operational resilience. In this environment, a Target Operating Model (TOM) is no longer a future-state diagram. It is the action blueprint that defines what will change, who owns outcomes, what guardrails apply, and how progress will be evidenced.

For executives validating strategy realism, the TOM functions as an execution contract. It makes constraints explicit—data readiness, platform dependencies, control requirements, and change capacity—so leaders can test whether strategic ambitions are feasible within current capabilities and risk tolerances. When those constraints are unclear, the portfolio tends to overcommit, delivery fragments across functions, and control evidence becomes inconsistent across lines of defense.

The six layers of a 2026 banking TOM that must move together

Business strategy alignment

Transformation becomes executable when the TOM expresses how the bank intends to compete—platform, ecosystem orchestrator, specialized utility, or hybrid—and translates that stance into explicit product and segment priorities. This layer defines the outcomes the bank is willing to fund, and the non-negotiables (risk appetite, resilience objectives, regulatory constraints) that govern delivery decisions.

Organizational structure and people

Operating models are evolving toward cross-functional domain teams where humans increasingly manage AI-enabled workflows and automation capacity. The practical shift is away from siloed handoffs toward accountable product and process ownership. A credible TOM specifies decision rights, role boundaries, and the talent model required to operate in an AI era—especially AI fluency, data stewardship, and control-aware engineering.

Process optimization

In a modern TOM, processes are redesigned around customer and business intents rather than job roles. For example, loan origination is treated as an end-to-end value stream with embedded controls and exception handling, not a series of departmental tasks. AI-driven automation can accelerate throughput, but only if the TOM defines how exceptions are routed, how evidence is generated, and where human-in-the-loop checkpoints are mandatory.

Technology and digital infrastructure

Technology design is shifting from monolith-centric modernization to modular assembly: thin, feature-rich cores; cloud-native services; and composable architectures that enable rapid API integration. In TOM terms, this layer must define the enterprise platforms and reference patterns domains are expected to reuse (identity, logging, API gateways, security baselines), as well as the boundaries for autonomy so local delivery does not become uncontrolled divergence.

Data and analytics

Agentic AI depends on data that is timely, consistent, and governed. The TOM must specify the real-time data foundation the bank is building, including ownership of data products, lineage expectations, quality thresholds, and access entitlements. Treating data as “fuel” becomes operational only when the operating model makes stewardship and control enforcement part of everyday delivery routines.

Risk, compliance, and governance

Governed intelligence requires controls by design. The TOM must embed accountability, explainability expectations, and escalation paths for AI-enabled decisions. This includes defining where human review is required, how model and agent behavior is monitored, and what constitutes a material failure state. The goal is to move from reactive recovery to proactive anticipation, with defensible evidence that can withstand audit and supervisory scrutiny.

Transformation priorities in 2026 and what the TOM must make explicit

AI integration: from pilot to productivity

Scaling specialized, production-grade agents for onboarding, servicing, fraud detection, and operations requires more than model selection. The TOM must define AgentOps-style ownership, monitoring, and change controls: who approves scope expansion, how drift is detected, how exceptions are handled, and what evidence is required to prove controlled performance.

Payments: enabling the invisible economy

Instant, programmable payments require modernization across rails, risk sensing, and customer experience layers. The TOM must align product, technology, and control design so new payment capabilities do not outpace fraud interdiction, dispute handling, and resilience requirements. Where stablecoin or tokenized settlement capabilities are explored, the TOM should clarify governance, risk ownership, and integration boundaries rather than treating these as purely technical pilots.

Open finance: growth via ecosystems

Moving beyond compliance-driven API programs requires operating model clarity: API product ownership, partner onboarding controls, consent and data sharing governance, and monetization accountability. The TOM should define what is standardized enterprise-wide (security, identity, consent, observability) and where domains can innovate to accelerate ecosystem partnerships.

Infrastructure: sovereignty by design

Regional data residency, model governance expectations, and concentration risk concerns are pushing banks toward sovereignty-by-design cloud patterns. The TOM must specify approved deployment architectures, data handling rules, and resilience objectives, along with how third-party and cloud risk management integrates into the delivery pipeline.

Trust and security: deepfake resilience

AI-enabled fraud raises the bar for identity assurance and continuous verification. A credible TOM embeds behind-the-scenes controls such as behavioral signals, device intelligence, and step-up verification rules, while ensuring privacy, consent, and auditability are enforced consistently across channels.

Practical design choices leaders must resolve early

Build vs buy as an assembly decision

Many banks are adopting an “assembly approach”: buying foundational capabilities (models, platforms, tooling) while building proprietary connectors, domain data products, and guardrails that reflect the bank’s risk posture and competitive differentiation. The TOM should specify which components are strategic assets, which are commodities, and what integration standards prevent a return to fragmented architectures.

Operational readiness through AgentOps

As agents become part of core operations, the bank needs an operating capability that treats them like production services: monitored, controlled, versioned, and governed. Whether labeled AgentOps, an AI CoE, or a federated governance layer, the TOM must define how responsibilities are split across first line delivery teams, second line oversight, and control functions, including evidence expectations and incident response.

Culture shift: technology as a defining capability

Execution speed and control strength increasingly depend on workforce fluency in AI, data stewardship, and disciplined engineering practices. The TOM should include explicit mechanisms for capability building—role-based upskilling, stewardship accountability, and incentives aligned to outcomes and control quality—so the organization can sustain change without degrading resilience.

How COOs translate the TOM into an actionable execution rhythm

A TOM becomes real when it dictates how the bank plans, funds, delivers, and governs change. COOs can operationalize this by establishing an execution cadence that links strategy to delivery evidence: quarterly outcome reviews, dependency and constraint management, risk-based release gating, and continuous performance telemetry across customer outcomes, operational KPIs, and control indicators.

Critically, the TOM should define sequencing logic. Enterprise foundations—identity, logging, data governance, resilience patterns, and policy-as-code controls—often determine how quickly domains can safely innovate. When those foundations lag, ambitious domain roadmaps become fragile and cost discipline erodes through rework and duplicated tooling. When foundations are in place, modular architectures and agentic workflows can scale without compromising governance.

Validating TOM ambition and sequencing with digital maturity evidence

Strategy validation and prioritization improves when leaders test whether the target operating model matches the bank’s actual capability baseline. The most common points of failure are predictable: data quality and lineage are insufficient for scaled agentic decisioning; identity and access controls do not extend cleanly to machine identities; observability is too weak to detect drift and operational failures early; and governance cadences cannot keep pace with the speed of modular delivery. A maturity-based view makes these constraints explicit, so executives can decide where to standardize foundations, where to permit domain autonomy, and what sequencing reduces operational risk.

Using a digital maturity assessment as an executive decision discipline strengthens confidence in the TOM as an action blueprint: it clarifies readiness across the TOM layers, quantifies the execution risk of key priorities, and ties funding to evidence-based gates. Within that framing, the DUNNIXER Digital Maturity Assessment can be used to evaluate whether the bank’s intended TOM—across strategy alignment, people and operating model, process and automation controls, modular technology foundations, real-time data readiness, and governance—can realistically deliver the stated transformation objectives without exceeding control and resilience tolerances.
