Tableau Migration in Lisburn
Tableau migrations for Lisburn organisations, where the calculations are the part that hides wrong answers. Expressions that operate at a different granularity from the view have no direct equivalent in most other tools, so a translated calculation frequently returns the right figure on the summary and a different one the moment somebody filters.
Why this comes up
The problem
Every dashboard was reproduced, the totals match, and a figure changes incorrectly as soon as a user applies a filter.
What you get
What we deliver
- Calculations rebuilt from intent rather than translated expression by expression
- Granularity-sensitive logic identified specifically, since it fails subtly
- Results verified with filters applied, not only on the default view
- Workbooks triaged by usage before effort is spent reproducing them
- Data source strategy redesigned for the destination platform's model
- Users involved in sign-off, because they recognise a wrong number faster than a test does

Tableau Migration in Lisburn — common questions
- Why are calculations the risky part?
- Because some of them operate at a granularity independent of the visual. Those have no straightforward equivalent elsewhere, and a translation that looks correct on a summary produces different results once anyone filters or changes the level of detail.
- How should results be verified?
- With filters and drill-downs applied, across several combinations. Comparing default views confirms very little, because the difference between a correct and an incorrect rebuild frequently appears only when the user does something other than look at the opening screen.
- Do all the workbooks need migrating?
- Rarely. Server usage data shows what is actually opened, and a meaningful proportion of any mature estate turns out to be abandoned — reproducing those spends real effort on content nobody will look at once it arrives.
- Who should sign off the migration?
- The people who read the reports weekly. Technical reconciliation catches totals that do not match; it does not catch a dimension that has been mapped plausibly and wrongly, and the person who knows the business is the only reliable detector of that.
- Do you work with businesses across County Antrim?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Lisburn and the surrounding County Antrim area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Lisburn businesses do you usually work with?
- Retail and light manufacturing systems for businesses serving the greater Belfast catchment. Beyond that we work across Manufacturing, Retail, Logistics, Food Production and Professional Services.
- Do you cover the areas around Lisburn?
- Yes — we work throughout Northern Ireland, including Belfast, Newry, Bangor. Lisburn is an urban area of roughly 120,000+, and we take on work across the wider County Antrim region rather than the city boundary alone.
