The dashboard nobody opens always loses to a spreadsheet somebody trusts
Sigma closes that gap: a spreadsheet interface sitting directly on top of your data warehouse, so anyone comfortable with a pivot table can filter, drill and build their own view without raising a ticket and waiting a week.
Input tables let them write assumptions back — budgets, quotas, forecast scenarios — into governed warehouse tables.
That’s how planning stops living in a file called final_v7_USE_THIS.xlsx.
Metric definition and modelling
Agree the definitions once (what counts as an active customer, when revenue is recognised) and build them into the model, not into twelve dashboards that quietly disagree
Workbook and dashboard build
Operational reporting, what-if scenario models, and write-back workflows built on live warehouse data rather than yesterday’s extract
Rollout, governance and enablement
Row-level security and access design, plus hands-on training so your team builds the next report without us
