These case studies document what actually happens when organizations engage Sparx Services to build, govern, and connect their Sparx EA practice. They cover the full spectrum of our work: from greenfield EA deployments to AI integration programs, and provide specific, honest accounts of situation, approach, and outcomes.
They are the most direct evidence of what Sparx Services does and what it delivers.
All engagements are anonymised by industry and organizational size. We do not publish client names without explicit permission. Metrics and outcomes are shared as reported or measured during the engagement. Where clients have reviewed and approved specific figures, those figures are marked as confirmed.
If you are evaluating Sparx Services and would like to speak with a reference client in your industry or situation, contact us and we will make introductions where possible.
A financial services group with 20,000+ employees and operations across 15 countries had accumulated more than 800 applications following three acquisitions. No current-state application portfolio existed in their Sparx EA repository. The architecture team was spending 60% of its time producing status reports from stale spreadsheet data rather than doing architecture work.
Sparx Services ran a Discover engagement to baseline the current state, then a Connect engagement to deploy EA GraphLink, build Power BI dashboards over the governed repository, and roll out Kernaro AI Hub for executive access. The result: 847 applications documented in a governed repository, Power BI dashboards refreshing daily, and the architecture team’s time on reporting reduced from roughly 60% to 20%. In the first executive portfolio review, 230 rationalization candidates were identified: a review that previously required two weeks of preparation was completed in two hours.
A UK central government agency managing a major digital transformation program had no EA capability at engagement start: no repository, no modeling standards, no architect skills, and a Cabinet Office TOGAF compliance mandate outstanding.
Sparx Services delivered a Discover engagement, then a Deploy engagement to stand up a governed Sparx EA repository with Pro Cloud Server, TOGAF package structure, and ArchiMate MDG technology, followed by a 12-month Amplify program covering team coaching, MDG governance development, and Architecture Review Board setup. A governed repository was live within 12 weeks of engagement start. The Cabinet Office compliance review was passed. Four junior architects progressed to mid-level proficiency within 12 months.
A global telecoms operator with 400+ architects and analysts using a well-governed Sparx EA repository had a different problem: architecture intelligence was locked inside the EA client. More than 200 business stakeholders had no direct access to architecture data. Monthly PowerPoint reports were consuming significant architect time.
Sparx Services ran an 18-week Connect engagement to deploy EA GraphLink across multiple repository databases, design a GraphQL schema optimized for TM Forum ODA-structured data, build a Power BI semantic model, and roll out Kernaro AI Hub to the non-technical stakeholder population. Live dashboards are now available to 200+ stakeholders, Kernaro AI Hub handles 50+ architecture queries per week without architect involvement, and architecture report production time has dropped from 40 hours per month to near-zero.
A regional health network operating across 8 hospitals began an EPR wave deployment program with no EA capability, no clinical system inventory, and no documentation of the 1,200+ HL7 v2 interfaces the new EPR platform would need to navigate. The program had 18 months to first wave go-live and no architecture team. Sparx Services ran a 22-week Discover → Deploy → Connect engagement: inventorying 400+ clinical applications, mapping every interface against wave deployment boundaries, and building a Wave Readiness Dashboard in Power BI that the EPR Program Board used to govern every go-live. Site 1 was completed without clinical integration failures: the first time in the network’s program history that a go-live at that scale had been achieved without integration-related clinical workarounds.
Every engagement starts with an honest conversation about your current state, your constraints, and what outcome would actually make a difference. If any of these case studies resonate with a problem you are facing, that is a good place to start.
