Master Data Management in Derry
Establishing master data for Derry organisations, where the difficult decisions are organisational rather than technical. When two systems hold a different address for one customer, something has to decide which wins — and that survivorship rule is a negotiation between the departments that own each system, not a configuration setting.
Why this comes up
The problem
Four systems hold the customer, they disagree, and every attempt to decide which is authoritative stalls in a meeting.
What you get
What we deliver
- Ownership agreed per attribute rather than per system, since it rarely divides cleanly
- Survivorship rules defined explicitly, including how conflicts are settled
- A golden record assembled and made available back to the contributing systems
- Match and merge logic tested against real records before it is trusted
- Stewardship assigned, because exceptions need a person rather than a rule
- Measurement in place, so improvement is demonstrable rather than asserted

Master Data Management in Derry — common questions
- Why is ownership per attribute rather than per system?
- Because different systems are authoritative for different things. Finance may own the billing address while the service system owns the delivery contact, and declaring one system the master for everything overrides departments who are genuinely better informed.
- What makes survivorship difficult?
- It is a policy decision disguised as a technical one. Choosing most recent, most complete or most trusted source produces different results, and the right answer varies by attribute — which is why it needs agreeing rather than defaulting.
- Do we need a dedicated platform?
- Not always. Smaller organisations achieve a great deal with a well-designed warehouse and disciplined process, and a platform pays off where the volume of records, sources and stewardship activity genuinely justifies it.
- Why assign stewards?
- Because rules cannot settle every case. Ambiguous matches and conflicting updates need a person with the authority to decide, and programmes that automate everything accumulate an unreviewed exception queue that quietly undermines the whole exercise.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
