How Consulting Firms Are Using AI to Transform Client Project Delivery

At industry conferences this year, I’ve spent dozens of hours inside conversations with CEOs, CDOs, CIOs and operating executives across financial services. When I ask what’s keeping them up at night when it comes to their data, the answer is remarkably consistent: data access. They want data more accessible, faster, in more usable form, in more places, with fewer gatekeepers.

What's notable is what they don't ask for. Not trustworthiness. Not audit-ability. Not the ability to defend a number to a regulator without calling three people first. Access is the ceiling of the conversation, and honestly, that makes sense. In large financial enterprises built on decades of legacy applications, murky integrations, and pipelines that nobody fully documented, just getting the data somewhere useful is still a meaningful achievement.

The problem is that "getting the data" is already more complicated than most leaders realize. The moment data leaves its source system, decisions are being made about it. Decisions that quietly change what it means. And if you don't know those decisions were made, you don't know what you're actually looking at.

That's where lineage comes in, and why it matters even before you get to the outcomes leaders should be asking for.

Below, I’ll walk through (1) what “access” really delivers, (2) the abstraction layer hidden inside every extraction, (3) the compounding problem of “data derivatives”, (4) a concrete example – encoding and precision – where this gets expensive, and (5) what business leaders should be asking for instead.

What “Data Access” Really Delivers

When a business team asks for access to data, they almost always receive something that has already been processed for their consumption. Someone – usually a data engineer or database administrator – sat down with the source system and made a series of decisions:

• Which tables matter for this use case

• Which fields to expose

• How to filter, aggregate, or join the records

• Which technical artifacts to strip out (temp tables, system metrics, audit fields that don’t translate to business meaning)

These decisions are reasonable. Business consumers don’t want raw operational data; they want something readable without extraneous noise. But every one of those decisions encodes logic and judgment that doesn’t travel with the data. The output looks complete – and to the business user, it looks like the source of truth – but it is already an abstraction.

The Extraction Event Is a Translation Event

I find it useful to think of an extraction as a translation. Someone translated the operational reality of a data storage system into a business-readable view. Like any translation, choices were made: what to keep, what to drop, how to render concepts that don’t map cleanly across contexts. And like any translation, those choices can quietly change the meaning.

When a business leader looks at the extracted view, the assumption is usually that the data was “moved and shifted” – that is, copied with fidelity. That assumption is possible. In my experience, it is also highly doubtful. Logic gets applied at the moment of extraction, and unless someone deliberately captured and shared that logic, it is invisible by the time the data reaches a dashboard.

Abstractions of Abstractions: How Data Derivatives Compound the Problem

Here is where it gets harder.

Once an extracted data set exists, other people start using it. And why wouldn't they? There is already a data access path. The alternative - forging a new data access path - is the full corporate yellow tape headache: hunting for a charge code, filling out a technical work request that Business can’t quite decipher, watching that ticket age in a queue, and depending on legacy data SMEs who left the company in 2019. The extracted data set skips all of that. Already shaped for consumption, already lightly documented, already trusted by some peer team who vouched for it in a meeting six months ago. So the next team builds a report off it. Or creates a derivative data set for their own use case. Or both. What they don't realize is that the easy path and the right path may not be the same one.

They use it because it’s available and easier than starting from scratch – it’s already shaped for consumption, already lightly documented, already trusted by some peer team. So they build a new report off it. Or they create a derivative data set for their own use case. Or both.

That derivative is now an abstraction of an abstraction. The further you move from the originating system, the more layers of unrecorded judgment sit between the business decision and the operational event the data was supposed to describe. By the third or fourth hop, the question “where did this number come from?” can be genuinely difficult to answer – even for the team that produced the report.

A Concrete Example: How Encoding and Precision Quietly Rewrite Your Data

Let me make this concrete with an example I keep encountering.

When data is moved between systems, engineers make practical choices about how to package it. One of those choices is how to handle numeric precision. A value originally stored at six decimal places in the source might be packaged at four, or two, depending on what the receiving system supports – or simply what the engineer is most familiar with.

In some industries, that’s fine. In financial services, insurance, and healthcare, it is often not fine. A decimal place in an interest rate, a reserve calculation, or a pricing model can represent material variance. Once precision has been silently reduced, the data is no longer the real data – it is an approximation that looks identical to a casual reviewer. The business consumer assumes they’re working with the underlying record; in reality, they’re working with a rounded version of it that was reshaped during packaging.

This is exactly the kind of change that lineage is built to surface. Without lineage, you can’t tell that anything happened. With lineage, the precision change is documented, traceable, and reviewable.

Why Regulated Industries Can’t Afford to Skip Data Lineage

Regulatory frameworks have been ahead of business intuition on this point. BCBS-239 requires banks to demonstrate the accuracy, completeness, and timeliness of their risk data – which is impossible to defend without lineage. ORSA and Solvency II require insurers to substantiate the data flowing into solvency and capital calculations. None of these frameworks ask whether you have access to the data. They ask whether you can prove what the data is and how it got there.

For institutions operating under these regimes, lineage isn’t a nice-to-have analytics enhancement. It is the substrate that makes the rest of the data conversation defensible.

What Business Leaders Should Be Asking For Instead

If “give me access to the data” is the wrong ask on its own, what’s the right one? In my view, business leaders should be asking three questions every time a new data set lands on their desk:

1. Where did this data originate, and what happened to it between then and now? Not a verbal summary – a documented path that is understandable in Business terms.

2. What decisions were made during extraction or packaging that could have changed the meaning of the values I’m looking at? Especially around encoding, precision, filtering, and aggregation.

3. If a regulator or auditor asked me to defend this number tomorrow, do I have the evidence trail to do it? If the answer is “we’d have to go find the engineer who built this,” the answer is no.

These questions don’t replace the access conversation – they extend it. Access is the entry point. Lineage is what makes access trustworthy.

A Final Thought

The reason business teams don’t ask for lineage isn’t that lineage doesn’t matter. It’s that the absence of lineage rarely announces itself. The data looks fine. The dashboard renders. The report mostly ties out. The risk lives in the assumptions you didn’t know you were making about what the data went through to get to you.

If your business teams are only asking for access, you have a gap – and in legacy environments where decades of undocumented logic sit between the source and the report, that gap is widest. The fix is to start asking for lineage too.

See Contextual Data Lineage in Action

Zengines Contextual Data Lineage is built for the environments where the lineage gap is widest – large financial enterprises with critical business logic locked inside COBOL, RPG, PL/1, and AS/400 code. We extract that embedded logic, make the data path visible, and give your teams the evidence trail they need to defend their numbers to auditors, regulators, and themselves.

If you’re working through a BCBS-239, ORSA, or Solvency II mandate, a planned mainframe migration, or a growing trust gap between your business teams and the data they consume, we’d like to hear about it.

In 2006, British mathematician Clive Humby coined a phrase that would define the next two decades of enterprise thinking: "data is the new oil." A decade later, in May 2017, The Economist made it a cover story – declaring data the world's most valuable resource and arguing that the data economy demanded a new approach to competition itself.

Twenty years after Humby first said it, the metaphor has only become more apt. What's changed is the catalyst. AI – and specifically the broad accessibility of large language models – has turned the abstract value of data into something organizations can now act on, at scale, in their actual operations. Every enterprise executive and Board member conversation I'm in today centers on the same question: are we positioned to scale value from AI?

The honest answer for most financial services enterprises is: not yet. And the gap isn't model selection, infrastructure, or use case prioritization. The gap is data readiness.

This post lays out what "AI-ready data" actually means in an enterprise context and the two capabilities that determine whether you have it.

What "AI-Ready Data" Actually Means

Strip away the hype, and AI-ready data comes down to two things:

1. The data has to be available – meaning it can be moved, accessed, and used by modern systems regardless of where it originally lived.
2. The data has to be trustworthy – meaning you know and can explain what it is, where it came from, and what business logic shaped it.

Both sound obvious. Neither is easy. And in older institutions with legacy applications – like in financial services – where institutions are sitting on decades of data stored across generations of systems, both require deliberate enterprise capability.

Pillar 1: Data Usability

Decades of preserved data only retains its value if the organization can keep it working. That means the ability to move it, transform it, and deliver it in a form whatever comes next can ingest; a new platform, a new analytics layer, an AI tool. Without that organizational capability, preserved data becomes stranded data.

Making data persistently usable across system changes is a data migration problem.

For institutions that have spent decades preserving customer records, transaction histories, account positions, and policy data, that preservation only translates into value if the data remains usable today. Not in the form it was stored in 30 years ago. In the form your current systems, your current analysts, and your current AI tools can ingest.

That's where data migration comes in – and where I'd encourage every executive to reframe how they think about it.

For most of the last 20 years, data migration has been treated as a one-time, project-bound activity tied to a specific systems initiative. A core conversion. A CRM rollout. An acquisition. A means to an end – the job had a start date and an end date, and once the data was "moved," the team and tools were disbanded.

That framing made sense in a world where systems changed every 10 to 15 years. It doesn't make sense anymore. The pace of modernization – driven by cloud adoption, AI tooling, vendor consolidation, and M&A – means data is constantly in motion. Treating each move as a bespoke, manually-staffed project is what makes modernization slow, expensive, and risky.

We built Zengines' data migration platform on a different premise: that data migration is a change capability, not a one-time activity. It's how you ensure your data remains an asset across every system change you'll make in the next 20 years – regardless of source format, target schema, or technology stack. That's what makes the underlying asset AI-ready: portable, repeatable, accessible.

For ISVs, BPOs, and MSPs onboarding clients onto modern platforms, the same logic applies and the economics are even more direct. Data conversion is, as I've argued before, a CEO-level concern – every client conversion that takes six months instead of six weeks is revenue deferred. Our platform compresses onboarding timelines by up to 80% by automating the manual work of mapping, profiling, transforming, and moving.

Pillar 2: Data Trustworthiness

Trustworthiness has many dimensions; data quality, governance, compliance controls. But none of those can be properly established without first answering a more fundamental question: what does this data actually represent, what logic produced it, where did it come from, and why does it look the way it does? That's a lineage problem, and it has to be solved before the rest can follow. In legacy-heavy environments, it's even harder to answer.

Trustworthiness matters on two distinct fronts:

First, the consumers of AI outputs; analysts, risk managers, portfolio teams; will act on what they trust. AI outputs will certainly attract interest; but that confidence erodes the moment someone is in a hot seat and can't explain a result, defend a decision, or reconcile an inconsistency. Without traceable source logic, that moment is a matter of when, not if.

Second, regulators are already examining AI model inputs. Under regulatory frameworks like BCBS 239, ORSA, Solvency II, "we trained on legacy system output" is not an explanation. The explanation lives in the code.

This is where data lineage matters, and where financial services has a particular challenge.

A significant portion of the data that drives banking, insurance, and asset management still flows through legacy systems – mainframes and the codebases that sit on them: COBOL, RPG, PL/1, Assembler. These systems weren't built to expose their logic to outside observers. The data they produce reflects calculations, conditional branches, and business rules that were written decades ago, often by people who have long since retired. When a CDO asks today, why does our risk exposure calculation produce this number?, the answer is buried in code that no current analyst can quickly read end-to-end.

At one Fortune 100 financial institution we work with, the environment includes nearly 100,000 COBOL modules. That's not unusual for an enterprise of that scale. It's the norm.

Without a way to expose the logic embedded in those systems, AI initiatives that touch this data are flying blind. You can train a model on the outputs, but you can't explain the outputs. You can move the data, but you can't verify what it represents. For regulated institutions, that's a non-starter.

This is the problem Zengines' Contextual Data Lineage solves. It parses legacy code – COBOL, RPG, PL/1 – and surfaces the business logic embedded inside: calculations, branching conditions, data origins, downstream dependencies. Instead of waiting nine months for a subject matter expert to reverse-engineer a single business rule, an analyst can answer the question in minutes. That's what makes legacy data not just movable, but explainable. And explainability is what makes data AI-ready in a regulated environment.

Why This Matters Now

The institutions making the most progress on AI right now aren't the ones with the most ambitious model strategies. They're the ones who've done the unglamorous work on the foundation – ensuring their data is preserved across system changes, and that the logic embedded in their legacy systems is documented, understandable, and ready to be replicated or retired with confidence.

That foundation is what allows AI initiatives to move from pilot to production to scaled value. It's what allows risk teams to validate AI-driven outputs against regulatory expectations  with confidence. It's what allows finance and operations teams to actually trust what AI is telling them.

The window to build this foundation is now. Every quarter spent treating data migration as a project – or treating legacy code as an unsolvable black box – is a quarter of AI value deferred.

Two Capabilities, One Outcome

AI-ready data isn't a destination. It's the natural outcome of two capabilities working together: the ability to move data through any transformation or modernization without losing it, and the ability to understand the logic that defines what the data means over time and pathways.

Zengines was built to deliver both. Our data migration platform makes data preservation and utility a repeatable, AI-accelerated capability. Our Contextual Data Lineage exposes the logic locked inside legacy systems so analysts, auditors, and AI tools can use it with confidence.

If your organization is wrestling with how to position your data for AI – whether that's preserving decades of records through modernization, or making your legacy systems explainable to your CDO, CRO, or your regulators – we should talk.

BOSTON, MA - May 8, 2026 - Zengines, Inc. today announced it has won Best of Show at FinovateSpring 2026, selected by audience and judges vote at the premier fintech demo event. The conference brought together more than 1,200 senior-level fintech and financial services executives - including 600+ from banks, credit unions, and financial institutions - to evaluate 50+ live product demonstrations.

Finovate recognized Zengines for its Contextual Data Lineage solution, citing the platform for "modernizing off mainframes without losing critical logic, satisfying auditors faster, and making legacy systems searchable so transformation and compliance don't stall."

Why it matters

Every financial institution running COBOL, RPG, or PL/1 has the same problem: the people who built those systems are retiring, regulators are asking questions the systems can't answer, and no one knows what a modernization program will actually touch until it's too late.

Zengines changes what's possible. Ask a plain-English question about your data. Get a complete, sourced answer - grounded in the actual logic embedded in the code, not a guess. Regulatory questions that took months get resolved in days. Migration risk gets quantified before work begins, not after.

Zengines is already working with a Fortune 100 financial institutions to navigate applications written in COBOL and RPG, each with more than tens of thousands of COBOL modules, cutting analysis time to minutes rather than months of manual research methods.

"Legacy system modernization has traditionally required a leap of faith - guessing what's in the code before you start rewriting it. We don't accept that. Contextual data lineage replaces guesswork with answers: regulatory questions resolved in days, business logic preserved through migration, and compliance that doesn't hinge on institutional memory. We're proving there is a better way to manage today and modernize tomorrow." - Caitlyn Truong, CEO and Co-Founder, Zengines
