Tableau Consulting in Derry
Tableau advice for Derry organisations, where the characteristic problem is duplication rather than capability. Every analyst who needed data slightly differently published their own connection, and the server now holds a dozen versions of the same source — each defensible, each maintained by one person, and none of them agreed.
Why this comes up
The problem
Six data sources describe the same sales data, they disagree at the margins, and each has a workbook depending on it.
What you get
What we deliver
- Duplicate data sources identified and consolidated into certified ones
- Certification used so users can tell which source is endorsed
- Ownership assigned per data source, since unowned ones drift
- Unused workbooks and sources retired based on actual usage data
- Extract refresh load reviewed where schedules are contending
- Publishing governance established, so consolidation is not undone within a year

Tableau Consulting in Derry — common questions
- How does the duplication happen?
- Reasonably, one workbook at a time. An analyst needs a field the existing source lacks, publishing a new one is quicker than getting the shared one changed, and after two years there are a dozen — each created by someone solving an immediate problem sensibly.
- What does certification achieve?
- It tells users which source is endorsed. Consolidation only holds if people can identify the right thing to use, and a certified badge on the source everyone should be using is a small mechanism that prevents a great deal of recurrence.
- How do we decide what to retire?
- From usage data rather than opinion. The server records what is opened and how often, and content untouched for a year is a strong candidate — with a notice period, since the exception is usually something used annually at a critical moment.
- Will the sprawl come back?
- Without governance, yes, within about a year. The fix is not restricting publishing entirely but making the shared sources good enough and responsive enough that creating a new one is genuinely the less convenient option for an analyst in a hurry.
- 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.
