Is your business ready for future-forward data leadership?


Discover how forerunners are accelerating governance and unlocking data leadership with CDO-as-a-Service.


In brief

  • Building an internal CDO function is slow, expensive and constrained by talent scarcity and rising regulatory pressure, pushing companies toward faster external solutions.
  • CDO-as-a-Service provides immediate access to data leadership, governance frameworks and compliance expertise, accelerating decision-making, trust and AI readiness.
  • Modular CDOaaS models scale with business needs, improving data quality, reporting speed and operational resilience while turning data maturity into a competitive advantage.

Data is becoming the defining currency of competitive advantage. Every strategic decision – from market cultivation to AI innovation – depends on how effectively an organization governs, structures and activates its data. As companies accelerate their digital and AI transformation, the chief data officer (CDO) has become a cornerstone of enterprise strategy. The role sits at the intersection of regulation, innovation and operational excellence.

Yet establishing an in-house CDO function is a long and complex journey. Recruiting qualified data leaders, building multidisciplinary teams and developing and operating a robust data governance office typically takes several years in large organizations before its value can be fully realized, often requiring multi-million-franc investments.

As a result, we are seeing a major shift, especially in industries where compliance and trust define market credibility, culminating in the rise of CDO-as-a-Service (CDOaaS). Leading organizations are increasingly integrating external data and governance experts directly into their operating models. Instead of spending years building an internal chief data office, they gain immediate access to mature data management services, proven frameworks and regulatory expertise.

Chapter 1

The challenge: regulatory complexity, talent scarcity and rising cost

Structural complexity has outpaced traditional data management

Most organizations did not design their data landscapes for today’s regulatory and analytical demands. Core transactional systems, risk platforms, data warehouses, cloud analytics stacks, ESG tooling and third-party data sources have been layered over decades. The result is not only technical complexity, but fragmented accountability: multiple versions of critical data, unclear ownership, inconsistent controls and limited end-to-end traceability.

In regulated industries, this fragmentation translates directly into operational and supervisory risk. Data issues rarely manifest as isolated technical defects; they appear as delayed reporting, reconciliation breaks, manual workarounds and reduced confidence in management information.

Talent scarcity and rising structural cost

Previously often neglected as a byproduct of operations, data has become a core business asset. However, building a high-performing internal CDO organization today is both slow and expensive. Global competition for data scientists, modelers, governance specialists and data architects has driven talent scarcity to unprecedented levels. Even when companies manage to hire, maintaining these skills in-house is difficult and costly.

The consequences of inadequate data governance are real and immediate: regulatory findings, delayed reporting, reconciliation errors and capital inefficiencies.

Regulation is shifting from reporting outcomes to data capabilities

At the same time, regulatory complexity is escalating. Financial institutions face strict oversight under FINMA, BCBS 239 and GDPR, alongside emerging ESG and AI governance frameworks. In banking, insufficient client and exposure data lineage can block regulatory reporting and delay capital planning. In insurance, fragmented exposure data impairs risk modeling and solvency reporting.

Importantly, supervisory expectations are no longer limited to the correctness of reported figures. Regulators increasingly assess the capabilities used to produce them, including:

  • defined data ownership and stewardship models
  • controlled data definitions and critical data elements
  • automated reconciliation and quality monitoring
  • auditable lineage from source to report
  • formal governance bodies and decision rights

Organizations that treat data governance as a side activity of IT or compliance find themselves reacting to findings instead of preventing them.

The hidden cost of “building it yourself”

Beyond hiring a senior CDO, a functioning data office typically requires governance leads, domain stewards, data quality specialists, metadata and lineage engineers, regulatory reporting experts and change management capacity. In practice, this translates into multi-year transformation programs with high fixed costs and uncertain outcomes.

For mid-sized institutions in particular, this model is difficult to justify economically: the investment profile resembles that of large global banks, while the available budgets and talent pools do not.

Opportunity cost: when data maturity delays business strategy

Against this backdrop, the option to “do nothing” and continue operating without a formal data governance framework is no longer viable. Organizations need mature, compliant data functions – but few can afford the time or cost to build them from scratch.

The most overlooked consequence is strategic inertia. AI initiatives stall because training data is unreliable. Mergers and system integrations take longer because data models are incompatible. New regulatory requirements trigger expensive remediation instead of structured adaptation.

It is this tension – between rising expectations and limited internal capacity – that is driving the rapid adoption of externalized data leadership models.

CDOaaS: the fast-track solution

To bridge the capability gap, many organizations are adopting CDO-as-a-Service solutions – an externalized, modular and scalable approach that delivers the leadership, governance and operational capacity of a full data office without the long and capex-intensive build-up period.

Organizations with strong data leadership see demonstrable business benefits: 43% higher innovation performance, 7% greater revenue growth and 9% more value generated from data according to a recent IBM CDO Study1. In addition, an Amazon Web Services study2 found that 63% of CDOs dedicate at least 20% of their time on data governance, underscoring the importance of a sustained governance function to drive impact. These advantages translate into reduced costs, faster decision-making and increased trust in data, enabling innovation across analytics, AI and digital transformation, all while establishing a solid foundation for future growth.

An external data leadership service doesn’t replace strategic intent; it accelerates it. The service provides structure, consistency and access to best practices grounded in established frameworks, such as DAMA and DCAM. Whether the need is strategic guidance, targeted capability enhancement or complete operational takeover, CDOaaS adapts to fit the organization’s size, regulatory exposure and data maturity level.

From role to capability: rethinking the CDO function

CDO-as-a-Service is not simply an outsourced executive role. It represents a shift from viewing the CDO as an individual to treating data leadership as an enterprise capability that can be modularized, industrialized and scaled.

Instead of building every component internally, organizations gain access to:

  • experienced data leadership (fractional or interim CDO roles)
  • proven governance and operating models
  • standardized tooling and control frameworks
  • regulatory expertise across multiple institutions
  • execution capacity across architecture, quality, metadata and reporting

This turns data management from a bespoke transformation effort into a managed capability with predictable outcomes.

Speed to control and credibility

Establishing baseline governance structures, ownership models, quality controls and reporting processes internally often takes 18–36 months. With CDOaaS, many of these foundations can be operational within a single planning cycle.

For regulated organizations, this speed directly affects audit readiness, remediation timelines, supervisory confidence and management’s ability to rely on data for strategic decisions.

An external data leadership service does not replace strategic intent; it accelerates it.

Strategic control remains internal

A frequent concern is the potential loss of ownership. In practice, a well-designed CDOaaS model preserves strategic control within the organization:

  • business priorities remain with executive management
  • data ownership stays with business domains
  • governance bodies include internal decision-makers
  • service scope remains modular and contractually adjustable

CDOaaS replaces execution bottlenecks; not accountability.

A bridge to long-term maturity

For some organizations, CDOaaS becomes a permanent operating model. For others, it functions as a transition mechanism: accelerating early maturity, stabilizing governance and enabling structured knowledge transfer until internal teams are ready to assume responsibility.

This flexibility differentiates CDOaaS from traditional consulting engagements or pure outsourcing arrangements and sets the stage for the integration models described in the next chapter.

CDOaaS integration models – a look inside the machine room

Every organization is at a different stage of its data journey. Our CDOaaS offering is designed to adapt accordingly from providing strategic guidance to fully operating your Data Office on your behalf. The models below show how we flex our role to match your maturity, capacity, and ambitions, ensuring you get the right level of leadership, execution, and impact at every stage.

figure 1

In our experience, the most effective CDOaaS solutions are modular and scalable, allowing organizations to choose the model that best aligns with their maturity and ambitions. Broadly speaking, our teams typically support four relatively distinct integration scenarios.

figure-2

Scale - Full Outsourcing: When speed, simplicity, and certainty are critical, the Scale model provides a fully managed Data Office operated end-to-end by EY. This includes appointing a fractional or interim CDO, running governance bodies, defining and enforcing data standards, managing data quality controls, maintaining metadata and lineage, and producing management and regulatory data reports. Clients benefit from immediate operational stability, predictable costs, and full accountability for outcomes without the need to hire or manage large specialist teams. This model is particularly effective in regulatory remediation programs, post-merger integrations, or large-scale data transformations where rapid industrialization is required.

The provider acts as an on-demand advisor to the existing CDO and leadership team, benchmarking practices, challenging assumptions and co-designing initiatives. This lightweight engagement delivers independent validation and access to data governance best practices – ideal for organizations seeking to refine strategy or accelerate specific initiatives.

Balance - CDO Function Enhancement: When strategic ambition outpaces internal capacity, the Balance model combines leadership support with hands-on execution. EY augments the client’s existing CDO function with experienced specialists who help deliver governance, data quality, architecture, and reporting initiatives faster and more reliably. For example, our team may help set up data ownership structures, implement a data catalogue, define critical data elements and quality rules, or build regulatory reporting controls while the client’s teams remain embedded in day-to-day operations. This approach removes resource bottlenecks, closes skill gaps, and accelerates progress, while ensuring knowledge is transferred and internal capabilities are strengthened over time.

External specialists are embedded into the internal data office to close critical skill gaps in data architecture, compliance or quality. They operate within existing cycles, offering precision support that delivers faster execution and knowledge transfer without causing disruptions. We find that this approach works well for organizations constrained by limited bandwidth or needing extra execution capacity for critical data initiatives.

 Reliability - Hybrid Model: For organizations without a mature Data Office, the Reliability model establishes a stable foundation for sustainable data management. EY takes responsibility for running core data management processes, such as operating governance forums, maintaining the data catalogue and lineage, monitoring data quality dashboards, and coordinating issue remediation with IT and business domains. At the same time, we work closely with client stakeholders to embed roles, processes, and accountability. This model creates consistency and transparency, reduces recurring data issues, and ensures that reporting and regulatory obligations are met reliably, even as internal capabilities are gradually built up.

Governance, quality management and regulatory alignment are co-managed between the external provider and internal teams. This ensures consistency, cost optimization and sustainable governance embedded in day-to-day operations. We typically find this model especially effective in regulated industries such as insurance and banking or for companies still in the process of developing a data office and accelerating their governance maturity.

Scale - Full Outsourcing: When speed, simplicity, and certainty are critical, the Scale model provides a fully managed Data Office operated end-to-end by EY. This includes appointing a fractional or interim CDO, running governance bodies, defining and enforcing data standards, managing data quality controls, maintaining metadata and lineage, and producing management and regulatory data reports. Clients benefit from immediate operational stability, predictable costs, and full accountability for outcomes without the need to hire or manage large specialist teams. This model is particularly effective in regulatory remediation programs, post-merger integrations, or large-scale data transformations where rapid industrialization is required.

For organizations still building their in-house data management structures – or start-ups that need to scale fast – full outsourcing delivers immediate uplift. The external provider assumes responsibility for data strategy, governance and compliance, embedding experts into existing decision-making processes. This model offers predictable costing, rapid compliance readiness and faster time to value. Fintechs frequently adopt this model to leapfrog capability gaps, and it can also be a highly cost-effective option for smaller, regional or fast-growing banks and insurance companies.

A modular approach to CDO-as-a-Service

The strength of CDOaaS lies in the options it provides for structured, modular design. Organizations may start with targeted initiatives such as improving reference data, automating quality monitoring, or implementing data lineage, and later expand toward a holistic enterprise data leadership model.

In our recommended approach, a data management lifecycle ensures that every data point – across creation, storage, use and deletion – is secure, compliant and high-quality. Surrounding this core are interoperable modules covering data governance, architecture, security, compliance and analytics operating models. Each module can function independently or combine to form a fully integrated chief data office.

figure 6

This modularity ensures scalability, consistency and cost efficiency – enabling organizations to evolve capabilities at their own pace – scaling services up or down in line with changing business priorities.

Our engagements typically begin with a discovery phase to assess data maturity, identify regulatory exposures and define the desired target operating model. From there, a multi-phased approach ensures sustained impact.

Through systematic assessment and gap analysis, a tailored roadmap and target operating model are created, defining roles, governance mechanisms and integration points. Execution then embeds solutions, controls and dashboards into daily operations, leading to measurable improvements in data quality, compliance and decision-making. Continuous delivery and scaling sustain this momentum, with regular reviews guiding optimization, risk reduction and the expansion of data-driven value across the organization.

Chapter 5

An approach that delivers value in multiple domains

A well-structured CDO-as-a-Service engagement delivers both immediate and long-term results. Quantitatively, our clients typically report 20-35% reductions in reconciliation errors, faster reporting cycles (accelerated by up to 40%) and improved audit readiness within the first 6-9 months.

CDO-as-a-Service assists compliance with FINMA, BCBS 239, GDPR and other global standards through built-in controls and documented governance mechanisms. The ability to demonstrate data lineage, traceability and quality control directly strengthens trust with regulators, investors and customers alike.

Carefully crafted CDOaaS helps organizations transition from AI experimentation to enterprise-wide adoption

Equally important, robust data foundations are the precondition for AI enablement. Without structured, well-governed data, machine-learning models fail to scale or deliver consistent results. By integrating governance and quality management from the outset, carefully crafted CDOaaS helps organizations transition from AI experimentation to enterprise-wide adoption – turning data risk into data advantage.

 

The operational gains are also tangible. We routinely see how streamlined processes, reduced duplication and clear accountability translate into faster reporting, more accurate analytics and better decision-making. Over time, this strengthens organizational resilience and builds a foundation for continuous innovation.

CDO-as-a-Service offers a pragmatic, scalable path to achieve this maturity without the time, cost and complexity of building an internal function from scratch. It empowers organizations to access top-tier expertise, proven frameworks and measurable results – all while retaining strategic control.

As regulatory expectations rise and data ecosystems grow more complex, data needs to be treated as a strategic opportunity. For organizations ready to accelerate data maturity, enhance AI readiness and secure long-term trust, CDO-as-a-Service is not just an operational shortcut – it’s a strategic lever for unlocking next-level innovation and gaining a sustained competitive advantage.

Summary

Data has become a core strategic asset, but building an internal CDO function is slow, costly and hampered by talent scarcity and rising regulatory demands. CDO-as-a-Service offers a fast, scalable alternative, giving organizations instant access to data leadership, governance frameworks and regulatory expertise. By accelerating compliance, improving data quality and enabling AI readiness, it turns data from a risk into a competitive advantage.
