Mainframe Managed Service Providers (MSPs) have built impressive capabilities over the last several decades. They excel at infrastructure management, code conversion, and supporting complex hosting environments. Many have invested millions in advanced tools for code parsing, refactoring, and other technical aspects of mainframe management and modernization. Yet despite these strengths, MSPs consistently encounter the same bottlenecks that threaten mainframe modernization project timelines, profit margins, and client satisfaction.
In this article, we’ll explore the most common gaps MSPs face, how Zengines platform helps fill those gaps, and why Mainframe MSPs are partnering with Zengines.
The Critical Gaps in Current MSP Toolkits
Gap 1: Business Rules Discovery
While MSPs have sophisticated tools for parsing and reverse engineering COBOL code—they can extract syntax, identify data structures, and map technical dependencies—they lack capabilities for intelligent business logic interpretation. These parsing tools tell you what the code does technically, but not why it does it from a business perspective.
Current approaches to understanding the embedded business rules within parsed code require:
- Manual analysis by teams of expensive mainframe experts and business teams to interpret the business meaning behind technical code structures
- Line-by-line COBOL review to understand calculation logic and translate technical operations into business requirements
- Manual correlation between parsed code elements and actual business processes
- Expert interpretation of conditional logic to understand business rules and decision trees
- Guesswork about the original business intent behind complex branching statements and embedded calculations
Even with advanced parsing capabilities, MSPs still need human experts to bridge the gap between technical code structure and business logic understanding. This discovery phase often represents 30-40% of total project time, yet MSPs have limited tools to accelerate the critical transition from "code parsing" to "business intelligence."
The result: MSPs can quickly identify what exists in the codebase, but still struggle to efficiently understand what it means for the business—creating a bottleneck that no amount of technical parsing can solve.
Gap 2: Data Migration Tools
A critical step in any mainframe modernization project involves migrating data from legacy mainframe systems to new modern platforms. This data migration activity often determines project success or failure, yet it's where many MSPs face their biggest challenges.
While MSPs excel at physical data ETL and have tools for moving data between systems, they struggle with the intelligence layer that makes migrations fast, accurate, and low-risk:
- Manual data mapping between legacy mainframe schemas and modern system structures—a time-intensive process due to guesswork of trial-and-error
- Insufficient data quality analysis relevant to the business context, leading to "garbage in, garbage out" scenarios in the new system
- Manual transformation rule creation that requires expensive technical resources and extends project timelines
- Limited validation capabilities to ensure data integrity during and after migration
- Rules-based tools that constantly need to be adjusted when the data doesn’t fit the expected pattern - more often then not, this is the case.
These gaps expose organizations to costly risks: project delays, budget overruns, compromised data integrity, and client dissatisfaction from failed transfers. Delays and cost overruns erode margins and strain client relationships. Yet the most significant threat remains post-go-live discovery of migration mistakes. Today’s approach of manual processes are inherently time-constrained—teams simply cannot identify and resolve all issues before deployment deadlines. Unfortunately, some problems surface only after go-live, forcing expensive emergency remediation that damages client trust and project profitability.
The result: MSPs can move data technically, but lack intelligence tools to do it efficiently, accurately, and with confidence—making data migration the highest-risk component of mainframe modernization projects.
Gap 3: Testing and Validation Blind Spots
Once data is migrated from mainframe systems to modern platforms, comprehensive testing and validation becomes critical to ensure business continuity and data integrity. This phase determines whether the migration truly preserves decades of embedded business logic and data relationships.
Without comprehensive understanding of embedded business logic and data interdependencies, MSPs face significant validation challenges:
- Incomplete test scenarios based on limited business rules knowledge—testing what they assume exists rather than what actually exists in the legacy system
- Inefficient testing based on what the code presents versus what actually exists within the data
- Manual reconciliation between old and new systems that's time-intensive, error-prone, and often misses subtle data discrepancies
- Inadequate validation coverage of complex business calculations and conditional logic that may only surface under specific data conditions
- Reactive testing methodology that discovers problems during user acceptance testing rather than proactively during migration validation
- Post-go-live surprises when undocumented logic fails to transfer, causing business process failures that weren't caught during testing
The consequences: validation phases that stretch for months, expensive post-implementation fixes, user confidence issues, and potential business disruption when critical calculations or data relationships don't function as expected in the new system.
The result: MSPs have inadequate and non-optimized testing where teams test what they think is important rather than what the business actually depends on.

Three Keys to Successful Mainframe Refactoring: A Practical Guide
With 96% of companies moving mainframe workloads to the cloud, yet 74% of modernization projects failing, organizations need a systematic approach to refactoring legacy systems. The difference between success and failure lies in addressing three critical challenges: dependency visibility, testing optimization, and knowledge democratization.
The Hidden Challenge
Mainframe systems built over decades contain intricate webs of dependencies that resist modernization, but the complexity runs deeper than most organizations realize. Unlike modern applications designed with clear interfaces, documentation standards and plentiful knowledge resources, legacy systems embed business logic within data relationships, file structures, and program interactions that create three critical failure points during mainframe refactoring:
Hidden Dependencies: Runtime data flows and dynamic relationships that static analysis cannot reveal, buried in millions of lines of code across interconnected systems.
Invisible Testing Gaps: Traditional validation approaches fail to catch the complex data transformations and business logic embedded in mainframe applications, leaving critical edge cases undiscovered until production.
Institutional Knowledge Scarcity: The deep understanding needed to navigate these invisible complexities exists only in the minds of departing veterans.
Any one of these challenges can derail a refactoring project. Combined, they create a perfect storm that explains why 74% of modernization efforts fail. Success requires ensuring this critical information is available throughout the refactoring effort, not left to chance or discovery during code transformation.
Key 1: Master Data Dependencies Before Code Conversion
The Problem: Runtime data flows and dynamic dependencies create invisible relationships that static analysis cannot reveal.
The Problem: Complex data flows and dynamic dependencies create invisible relationships that span program execution flows, database navigation patterns, and runtime behaviors.

What It Looks Like in Real Life
Manual Approach: Testing teams manually create hundreds of test cases, then spend weeks comparing data outputs from old and new systems. The sheer volume of data transformation points makes comprehensive coverage impractical—when data discrepancies appear across thousands of calculation steps, teams have no way to trace where in the complex multi-program data flow the difference occurred. Manual comparison of data transformations across interconnected legacy systems becomes impossible at scale.
With Zengines: Enable test generation automation to create thousands of data scenarios based on actual processing patterns. Self-service validation at every data transformation checkpoint to pinpoint exactly where refactored logic produces different data results—down to the specific calculation or business rule application.

What It Looks Like in Real Life
Manual Approach: Junior developers submit tickets asking "What happens if I change this customer validation routine?" and wait 2 weeks for Frank to review the code and explain the downstream impacts. The interconnected nature of decades-old systems makes it impractical to document all relationships—Frank might remember 47 downstream systems, but miss the obscure batch job that runs monthly. The breadth of institutional knowledge across millions of lines of code is impossible to capture manually, creating constant bottlenecks as project velocity crawls.
With Zengines: Any team member clicks on the validation routine and instantly sees its complete impact map—every consuming program, all data flows, and business rules. Questions get answered in seconds instead of weeks, keeping modernization projects on track.
Success Metrics

Take Action
Successful mainframe refactoring demands more than code conversion expertise. Organizations that master data dependencies, implement lineage-driven testing, and democratize institutional knowledge create sustainable competitive advantages in their modernization efforts. The key is addressing these challenges systematically before beginning code transformation, not discovering them during production deployment.
Next Steps: Assess your current capabilities in each area and prioritize investments based on your specific modernization timeline and business requirements.
Executive Leadership Guide: Mainframe Data Lineage as Strategic Risk Management
Your mainframe processes billions in transactions daily, but three critical risks could blindside your business tomorrow. Whether you're steering operations as CEO or providing oversight as a board member, mainframe data lineage isn't just technical infrastructure—it's your shield against reputational and financial catastrophe.
For the CEO: Reputation, Revenue and Risk
As a CEO running a business on mainframe core, your competitive advantage may be sitting on a ticking time bomb. Here are the three critical questions every CEO must ask their CTO:
1. Skills Crisis Reality Check
"How many of our mainframe experts are within 5 years of retirement?" If that number is above 40%, you're in the danger zone. The knowledge walking out your door isn't replaceable with a job posting. Comprehensive mainframe data lineage documentation is not optional – it must capture not just what the code does, but how data flows through your critical business processes.
2. Regulatory Exposure Assessment
"Can we trace every customer data point from source to report within 24 hours?" If the answer is anything but "yes," your reputation is at risk. Regulators don't care about mainframe complexity, they care about data accuracy and auditability. Mainframe data lineage isn't optional, it's your insurance policy against million-dollar compliance failures.
3. Revenue Impact Visibility
"When mainframe data feeds our analytics wrong, how quickly do we know?" If your team can't answer this, you're making business decisions on potentially corrupted data. Mainframe data lineage answers questions about data sources, data flows and run-time considerations – which inform system changes before they impact customer experience or financial reporting.
For the Board Member: Governance and Fiduciary Responsibility
Board members face unique oversight challenges when it comes to mainframe risk. Your fiduciary duty extends to technology risks that could devastate shareholder value overnight. Here are the three governance priorities for your executive team:
1. Data Lineage Audit Readiness
Quarterly "Data Integrity Dashboard" reporting is non-negotiable, showing complete mainframe data lineage coverage. Your executive team must demonstrate: Can we trace every regulatory report back to its mainframe source data? How quickly can we identify data issues before they become compliance violations? Red flag: If they can't show data lineage maps for your core, your audit risk is unacceptable.
2. Knowledge Preservation Strategy
Documented mainframe data lineage that captures retiring experts' institutional knowledge is essential. Key question: "When our senior mainframe developer retires, will the next person understand how customer data flows through our systems?" If management can't show comprehensive data lineage documentation, you're gambling with operational continuity.
3. Real-Time Risk Monitoring
Establish automated mainframe data lineage monitoring with board-level dashboards. Essential metrics: Data quality scores, lineage completeness percentage, time to detect data anomalies. The question that should drive executive action: "If our mainframe data feeds incorrect information to regulators or customers, how fast do we know and respond?"
Executive Action Framework
For CEOs: 90-Day Implementation Plan
Challenge your IT leadership to implement foundational, automated mainframe data lineage tracking within 90 days. Don't accept "it's too complex" as an answer. The businesses that can prove their data integrity while competitors guess at theirs will dominate regulatory discussions and customer trust.
Your mainframe data lineage isn't just compliance – it's competitive intelligence about your own operations.
For Board Members: Governance Oversight Framework
Establish clear data lineage requirements as part of your risk management framework. Set measurable targets: 95% mainframe data lineage coverage with automated data quality monitoring across all critical flows within 12 months.
Most importantly: Make mainframe data lineage a standing agenda item, not buried in IT reports. Your ability to defend data accuracy in regulatory hearings depends on it.
The Strategic Imperative
Whether you're making operational decisions as a CEO or providing oversight as a board member, mainframe data lineage represents the convergence of risk management and competitive advantage. Organizations that master this capability while competitors remain in the dark will define the next decade of business leadership.
The question isn't whether you can afford to implement comprehensive mainframe data lineage—it's whether you can afford not to.
How confident is your leadership team in the data flowing from your mainframe to your most critical business decisions?
The Billion-Dollar Cost of Operational Blindness
The financial services industry is learning expensive lessons about the true cost of treating mainframe systems as "black boxes." Over the past few years, three major banking institutions have paid nearly $1 billion in combined penalties—not for exotic trading losses or cyber breaches, but for fundamental failures in data visibility and risk management that proper mainframe data lineage could have prevented.
With mainframes processing 70% of global financial transactions daily, 95% of credit card transactions, and 87% of ATM transactions, these aren't isolated incidents—they're wake-up calls for an industry that can no longer afford operational blindness in its most critical infrastructure.
JPMorgan's $348M Wake-Up Call: When Trading Data Goes Dark
In March 2024, JPMorgan Chase paid $348 million in penalties for a decade-long failure that left billions of transactions unmonitored across 30+ global trading venues. The US Federal Reserve and Office of the Comptroller of the Currency found that "certain trading and order data through the CIB was not feeding into its trade surveillance platforms" between 2014 and 2023.
This wasn't oversight—it was systematic breakdown of market conduct risk controls required under US banking regulations.
The Mainframe Connection
JPMorgan, like 92 of the world's top 100 banks, relies heavily on mainframe systems for core trading operations. These IBM Z systems process the vast majority of transaction volume, but the critical problem emerges when trading data originates on mainframes and feeds downstream surveillance platforms. Without comprehensive data lineage, gaps create dangerous blind spots where billions in transactions can slip through unmonitored.
The $348 million penalty signals that regulators expect complete transparency in data flows. For banks running critical operations on mainframe systems without proper data lineage, JPMorgan's experience serves as an expensive reminder: you can't manage what you can't see.
Citi's $536M Data Governance Breakdown: A Decade of Blindness
The pain continued with Citibank's even costlier lesson. In October 2020, Citi received a $400M penalty from the Office of the Comptroller of the Currency, followed by an additional $136M in combined fines in 2024 from both the OCC and Federal Reserve—totaling $536M for systematic failures in data governance and risk data aggregation that regulators called "longstanding" and "widespread."
The Core Problem
The OCC found that Citi failed to establish effective risk data aggregation processes, develop comprehensive data governance plans, produce timely regulatory reporting, and adequately report data quality status. Some issues dated back to 2013—nearly a decade of compromised data visibility.
The Mainframe Reality
Like virtually all major banks, Citi runs core banking operations on mainframes where critical risk data originates. Every loan, trade, and customer transaction flows through these platforms before being aggregated into enterprise risk reports that regulators require. The problem? Most banks treat mainframes as "black boxes" where data transformations remain opaque to downstream risk management systems.
Citi's penalty represents the cost of operational blindness in critical infrastructure. The regulatory failures around data governance and risk aggregation highlight exactly the kind of visibility gaps that comprehensive mainframe data lineage addresses.
Danske Bank's $2B+ Problem: BCBS 239's Persistent Challenge
The pattern culminates with Danske Bank's ongoing struggle, which has resulted in $2B+ in penalties since 2020. While these stemmed from various violations, many could likely have been exposed earlier through proper BCBS 239 compliance. The bank's transaction monitoring failures and AML deficiencies represent clear gaps in the comprehensive risk data aggregation that BCBS 239 requires.
BCBS 239: Banking's Most Persistent Challenge
Nearly 11 years after publication and 9 years past its deadline, BCBS 239 remains banking's most persistent regulatory challenge. The November 2023 progress report reveals a sobering reality: only 2 out of 31 global systemically important banks achieved full compliance. Not a single principle has been fully implemented across all assessed banks.
The Escalating Consequences
The ECB has made BCBS 239 deficiencies a top supervisory priority for 2025-2027, explicitly warning that non-compliance could trigger "enforcement actions, capital add-ons, and removal of responsible executives." With regulatory patience exhausted, the consequences are no longer just financial—they're existential.
The Mainframe Blind Spot: Why Traditional Approaches Fail
Most BCBS 239 discussions miss a critical point: the majority of banks' risk data originates on mainframe systems that handle core banking operations and risk calculations. The Basel Committee's assessment highlights the core issue: "Several banks still lack complete data lineage, which complicates their ability to harmonize systems and detect data defects."
With mainframes handling 83% of all global banking transactions, understanding these systems is no longer optional. Yet banks continue to struggle because:
- Legacy Complexity: Decades-old COBOL programs lack documentation and follow code patterns that traditional lineage tools can't interpret
- Operational Opacity: Data transformations through complex JCL jobs, VSAM files, and DB2 operations remain invisible to downstream risk management systems
- Technical Barriers: Business analysts can't access or understand mainframe data flows without deep technical expertise
How Mainframe Data Lineage Solves the Crisis
The solution lies in comprehensive mainframe data lineage that addresses these fundamental blind spots:
Complete Visibility: Modern tools can trace data flows from mainframe CICS transactions through DB2 operations to downstream systems, mapping exactly how critical risk data moves through complex transformations that conventional tools miss.
Business Accessibility: The right platforms enable business analysts to discover and act on mainframe information without requiring technical expertise—transforming data lineage from technical obscurity into actionable business intelligence.
Automated Monitoring: Real-time tracking of mainframe batch processes detects when critical risk calculations fail or produce inconsistent results, preventing the systematic failures that cost JPMorgan, Citi, and Danske Bank billions.
Regulatory Preparedness: Banks can trace exactly where specific data resides within mainframe environments and extract it rapidly when regulators demand it—the core capability that BCBS 239 requires.
The Regulatory Survival Imperative
After a decade of BCBS 239 implementation struggles and nearly $1 billion in recent penalties, it's clear traditional approaches aren't working. Banks still wrestling with data aggregation challenges haven't invested in understanding their mainframe data flows.
The evidence is overwhelming:
- JPMorgan's trading surveillance gaps cost $348M
- Citi's data governance failures cost $536M
- Danske Bank's ongoing compliance failures exceed $2B
- Only 2 of 31 major banks achieve full BCBS 239 compliance
With the ECB intensifying enforcement and supervisory patience exhausted, mainframe data lineage isn't just modernization—it's regulatory survival infrastructure.
The Path Forward: From Black Box to Transparency
The financial services industry stands at a crossroads. Banks can continue treating mainframe systems as mysterious legacy platforms while paying escalating regulatory penalties, or they can invest in the comprehensive data lineage capabilities that modern compliance demands.
The choice is clear: illuminate your mainframe data flows or continue paying the billion-dollar cost of operational blindness. With regulators expecting rapid and recurring risk data aggregation, banks can no longer afford to manage what they cannot see.
Ready to illuminate your mainframe data flows and achieve regulatory compliance? The path forward starts with understanding what you can't currently see—before regulators demand answers you can't provide.
