Validation Questions
Start: The Board Gave You a Deadline — Tell Us the Story
- What was the exact board mandate or trigger that started this modernization conversation?
- What is the deadline the board set (or the window they expect) for delivering digital account opening capability?
- Who at the executive level is most invested in meeting that deadline (title or names)?
- How would you describe the tone from the board—urgent, cautious, financially strict, politically sensitive, or other?
- What happens if the deadline is missed—what are the consequences the board or exec team has communicated?
- If you could summarize in one sentence what success looks like to the board, what would it be?
Are We Building the Future or Stacking Two Platforms for Years?
- Do you accept the risk of running a legacy and new platform concurrently for multiple years, or is single-platform transition non-negotiable?
- Please quantify your current mainframe footprint: number of cores/apps, years in production, and approximate % of transactions flowing through it.
- Which middleware, third-party layers, or bolt-on systems were added after serial M&A and are hardest to untangle?
- What percentage of your annual IT budget is currently spent on maintenance and run-rate support (best estimate)?
- How confident are you that your documented inventory reflects the true estate (apps, interfaces, batch jobs)?
- Who holds the deepest institutional knowledge of the legacy systems, and how likely are they to stay through migration?
Who Really Pulls the Levers Here?
- If the modernization introduces any regulator comment or examiner question, who must be briefed and who signs off before going forward?
- Beyond CIO and CFO, which roles must be engaged—Head of Regulatory, Chief Risk Officer, business-line heads, operations—and who has final say?
- How structured is the governance forum you expect for this program (steering committee cadence, escalation path, decision SLAs)?
- How does the Head of Regulatory typically evaluate an integrator—references, interviews, prior exam language, or something else?
- Describe a recent executive decision where competing priorities (speed vs. risk vs. cost) forced a compromise—what was chosen and why?
Show Me Measurable Wins—or We Can’t Sign
- What minimum cost-takeout or run-rate reduction per phase will satisfy the CFO and keep the program funded?
- How do you currently measure run-rate cost—by application, by FTE, by vendor spend, or a blended metric?
- What acceptance criteria must be met at each phase before commercial payments or next-phase funding is released?
- Who in finance will validate the cost-takeout numbers (controller, FP&A, external auditor)?
- Would you accept an external third-party cost validation (e.g., independent run-rate audit) as part of phase acceptance?
- How should savings be tracked and reported—quarterly dashboards, rolling 12-month view, or milestone-based snapshots?
What Would 'Safe' Look Like to Your Regulators?
- What specific evidence or artifacts would satisfy your regulator that risk remains controlled during migration?
- Has your institution had recent OCC/FDIC examiner findings related to technology, vendor oversight, or data quality that we need to consider?
- How closely do exam cycles constrain your production cutover windows (must avoid exams, can align, or no constraint)?
- Would the regulator require interviews with our proposed project director and lead architect before sign-off?
- What format of regulator-facing documentation do you prefer—executive brief + technical annex, or full risk assessment and test evidence?
If This Stalls, What Breaks First?
- Which single outcome would you consider mission-critical to protect if a phase stalls (customer onboarding, transaction integrity, liquidity reporting, regulatory compliance)?
- Rank the top three program risks you fear most: scope creep, data remediation delays, institutional knowledge loss, vendor delivery failure, cost overruns.
- How long can the organization tolerate running parallel operations before costs or operational risk becomes unacceptable?
- What contingency reserves (time or budget) have you set aside for unexpected remediation or extended parallel runs?
- Tell us about a past IT program that stalled—what were the root causes and what lessons should we apply to avoid repeating them?
How Do You Want to See the Work Sequenced Around Exams and Business Cycles?
- Do you prefer a phased approach that delivers measurable functionality and cost reductions each quarter, or larger waves that consolidate risk but deliver bigger chunks less often?
- Which business processes should be in the earliest phases because they unlock the most value or reduce the most risk?
- What are your hard no-go windows for cutovers and why (peak business periods, regulatory exams, seasonal processing)?
- What level of parallel-run validation do you require—full synthetic reconciliation, partial shadow mode, or business-line spot checks?
- What rollback triggers would force an immediate stop and rollback to the legacy platform?
People, Roles, and Who's Actually Doing the Work
- Do you have internal SMEs and dedicated FTEs who will be assigned to this program, or will resources be nominated on an as-needed basis?
- Which roles must remain in-house for compliance or continuity (data stewards, core ops leads, security owners)?
- How do your teams feel about change—energized, cautious, or resistant—and how has that manifested in prior large tech changes?
- What training, shadowing, or knowledge-transfer cadence do you want built into each phase to minimize knowledge loss?
- Who will own day-to-day decisions on technical trade-offs—your CTO office, a program director, or a joint governance team?
Data and Integrations: What Keeps You Up at Night?
- How would you describe current data quality and reconciliation maturity across accounts, customer records, and transaction history?
- Which datasets are most fragile or mission-critical during migration (e.g., balances, loans, KYC, transaction history)?
- What level of environment access will our teams need for profiling, testing, and reconciliation, and are there constraints (masking, PII rules)?
- Do you have existing reconciliation tools or automated data pipelines we should integrate with, or will reconciliation be manual initially?
- What acceptable error rates or reconciliation tolerances will the business accept during parallel runs?
Decision, References, and Regulatory Proof: What Will Make You Press 'Go'?
- What evidence from an integrator would make the Head of Regulatory comfortable—case studies, examiner testimonials, direct reference calls, or shadowed demos?
- How important is working with a team that’s bank-specialist rather than a generalist consultancy when it comes to passing exams?
- How will you validate the proposed project director and lead architect—live interviews, recorded sessions, or onsite meetings with your regulators present?
- Are there procurement or contractual checkpoints that must be cleared before technical work can begin (insurance, SOC reports, SLAs)?
- What reference profile matters most—banks of similar asset size, same core platform experience, or documented regulatory-friendly migrations?
Near-Term Next Steps: What Will Put This Program on a Safe Path?
- If we agreed on a pilot or discovery sprint next, how soon could you commit to start (and what would 'start' look like)?
- What are the top three milestones you need to see in the first 90 days to feel this is going in the right direction?
- How would you prefer progress and risk updates—weekly tactical, biweekly steering, monthly exec summaries, or a mix?
- Which single metric would convince your CFO and board this program is on-track (cost takeout %, time-to-live for digital account opening, regulator sign-off, or another)?
- Who should we put in the room for a 90-minute discovery working session to validate assumptions and co-design the first phase?
