Tableau Development in Derry
Tableau dashboards and data sources for Derry organisations. Tableau's strength is exploratory analysis — letting an analyst follow a question wherever it leads — and its cost profile reflects that, so it earns its place where people genuinely investigate rather than read a fixed monthly report.
Why this comes up
The problem
Tableau was bought and is being used to produce static monthly reports. Licences are expensive, workbooks are slow, and the exploration it was chosen for is not happening.
What you get
What we deliver
- Published data sources, so definitions live once rather than per workbook
- Extracts and live connections chosen deliberately against freshness and load
- Dashboards designed for a question, not a wall of every available chart
- Performance work — most slow workbooks are fixable without new hardware
- Governance on Server or Cloud, so certified content is distinguishable
- Training for the analysts who will actually build, since that is the point of Tableau

Tableau Development in Derry — common questions
- Is Tableau worth it over Power BI?
- Where genuine exploratory analysis happens, often yes — the interaction model suits following a question. Where the need is fixed reporting inside a Microsoft estate, Power BI is usually the more economical answer, and we would say so rather than defend the incumbent.
- Why are our workbooks slow?
- Typically too many marks on a view, live connections to a slow source, or complex calculations evaluated per row. Most performance problems are design problems, and the performance recorder identifies them faster than guessing does.
- Extract or live connection?
- Extracts for speed and to protect source systems from dashboard load; live where the data genuinely must be current to the minute. Live connections are chosen far more often than they are needed, and the cost lands on the source database.
- How do we stop workbook sprawl?
- Published, certified data sources and a clear distinction between sanctioned content and personal exploration. Without that, definitions fork across workbooks and the exploratory freedom that justified Tableau becomes the reason nobody trusts the numbers.
- 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.
