Data, BI and dashboards

Organizing databases, modeling KPIs and building dashboards in Power BI and Excel. So reports stop being assembled by hand and every number has a known source.

What usually improves

  • Reports that refresh with no manual assembly
  • One number for each metric
  • Deviations visible while there is still time to act
  • Time spent on analysis instead of spreadsheets

How much each point improves depends on the environment: volume, structure and data maturity. That is why no percentage is promised here. The assessment measures the current situation and defines, before any work starts, how the gain will be measured.

Diagnosis

Signs this solves your problem

  • The monthly report is put together by copying and pasting spreadsheets.
  • Each team has a different number for the same metric.
  • The dashboard exists, but nobody trusts it.
  • Problems only show up at month-end, when it is too late to act.

Delivery

What gets done

  • Source consolidation

    Power Query, SQL and Python to standardize and combine databases that live apart today.

  • KPI model

    KPIs with a written definition and a single place for each calculation, kept separate from presentation.

  • Executive dashboards and reports

    Power BI and Excel with a leadership view and operational detail, refreshed from the source.

  • Total validation

    Checks that flag when a total does not add up, before the number reaches the meeting.

Most-used tools

  • Power BI
  • DAX
  • Power Query
  • Advanced Excel
  • SQL
  • Python

Analysis of overtime and payroll components

Context
The origin of a consolidated overtime total had to be explained, and the amounts then broken down by person.
Approach
The total rebuilt from the individual entries, each component validated and the amounts distributed by employee in order of impact.
Outcome
An aggregate number turned into an auditable analysis, traceable from the grand total to pay items and individuals.

Demo model

Executive reporting model

Context
A leadership report assembled by hand every month, with numbers of untraceable origin and deviations noticed only after the month had closed.
Approach
An Excel model with 9 source tables, an isolated calculation engine, 16 automatic alert rules and 11 reconciliation checks, feeding 12 report pages from a single control cell.
Outcome
No number typed in by hand: changing the reference month updates the entire report, and any leadership metric can be traced back to its source table.
