The Mega-Merger
“Three hospitals acquired. Four EHR systems. One patient nearly got the wrong blood type.”
Inspired by: Northeast Alabama RMC + EMPI industry stats
DPR Arena · Data Project Roleplay
Nine real MDM, data-quality and governance scenarios. Pick a role, work the board, defend your decisions against teammates armed with numbers.
Hold on. Before we pick architecture, I need the real constraints, not the pretty PowerPoint version. REGISTRY keeps source records where they are: minimal disruption, but fraud can't see linked patterns in real time. HUB gives the fraud team one view across all 5 CRMs. You don't get both in 9 months.
And cost check: the hub route is ~$800K in software licence alone. Which matters more for the board: real-time fraud visibility, or not breaking CRM workflows mid-project? Pick one.
Every scenario drops you into a working project with an AI team that holds its ground. Here is what that buys you:
Nine scenarios · real enterprise stakes
“Three hospitals acquired. Four EHR systems. One patient nearly got the wrong blood type.”
Inspired by: Northeast Alabama RMC + EMPI industry stats
“Same customer, five different records, three different credit limits. Marketing just sent them three copies of the same catalogue.”
Inspired by: RS Group (Informatica) + Schneider Electric (Reltio)
“GDPR fine: up to 4% of global turnover. KYC backlog: 45,000 cases. The regulator's letter arrived on Monday.”
Inspired by: Citizens Bank (Informatica) + KYC/AML industry challenges
“Same TV. Eight countries. Eight different descriptions. The customer in France got specs in German.”
Inspired by: MediaMarktSaturn (Stibo) + Office Depot
“They paid the same supplier twice — through two different ERPs. $2.3M in duplicate payments last year alone.”
Inspired by: Ivalua + Gartner procurement stats
“One customer. Five ordering channels. Five different loyalty accounts. None of them connected.”
Inspired by: Domino's (Profisee) + QSR industry challenges
“Sixty-seven separate MDM systems. Sales reps wait 8 days for customer setup. The compliance team just found patient data in 14 unsanctioned spreadsheets.”
Inspired by: AstraZeneca (Reltio) — 67 on-prem MDM instances consolidated to 3 cloud hubs; HP (Reltio) — 1.4B profiles; Pfizer — 30M customers across 140 countries
“The acquiring bank wants all 5.2 million customers on the new platform by April. Your predecessor was fired for saying it couldn't be done.”
Inspired by: TSB Bank (2018) — $330M loss, 1.9M customers locked out; Knight Capital ($440M in 45 min); NHS NPfIT ($12.7B failure)
“The breach cost $47M. The board asked 'Who owns this data?' Nobody could answer.”
Inspired by: HEINEKEN (Collibra) — 85,000 employees; Equifax breach ($700M); Ataccama/Raiffeisenbank — GDPR compliance; T-Mobile (Ataccama) — $425M savings
Architect, MDM developer, steward, integration lead, delivery manager. Your perspective shapes the project and what the team expects from you.
Real project tasks organised by phase (Discovery → Build → Validate → Deploy) with a full RACI matrix. Check off what you own.
Teammates challenge your thinking, bring cost and risk numbers, and force trade-offs, then leave the decision to you.
Every scenario carries success criteria drawn from actual vendor case studies: duplicate rates, false-positive targets, go-live clocks.
A free 90-second diagnostic reads your data team's structure: staffing gaps, role collisions, and the person quietly holding four jobs.
Two free judgment agents. Paste a data sample and the DQ Profiler gives you a verdict — including refusing to profile it. Describe a challenge and the Solution Architect designs it end to end, and tells you when you don't need the hub you asked for.
