Tableau Migration in Wrexham

Tableau migrations for Wrexham 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 Wrexham — 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 Wrexham?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Wrexham and the surrounding Wrexham area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Wrexham businesses do you usually work with?
Manufacturing and food production systems for businesses on the border serving North West England customers. Beyond that we work across Manufacturing, Food Production, Logistics, Higher Education and Retail.
Do you cover the areas around Wrexham?
Yes — we work throughout Wales, including Chester, Liverpool, Bangor. Wrexham is an urban area of roughly 65,000+, and we take on work across the wider Wrexham region rather than the city boundary alone.
