Reporting, rationalized.

From 15,000 reports to a single source of truth. A usage-driven rationalization that cut report sprawl by more than 90%, aligned the business on one set of KPIs, and rebuilt trust in the numbers so data actually got used again.

Decisions on evidence, not opinion. Every report scored on hard server-log usage and metric overlap, and validated for data parity before anything was retired.

The challenge

Report sprawl, and an atrophied muscle

A decade-old Cognos platform had turned into report sprawl: more than 15,000 weekly and monthly operations and finance reports, heavily customized, with little quality control or KPI management. Different teams owned near-duplicate reports and built downstream processes on their own datasets, so nothing tied out. Trust in the numbers eroded, retrieval got expensive, and the analytics muscle atrophied. When data is sprawling and hard to trust, people simply stop using it.

Market and corporate leadership measured outcomes differently and pulled in different directions. The organization did not need more reports. It needed a shared, trusted view of the business.

The approach

Inventory, classify, rebuild, govern

Count what is actually used

Pull real server logs, not opinions, to see execution frequency, unique views, and the true active-consumer list for every report.

Four dispositions, one rule set

Every report is scored on usage and overlap, then sorted to Retire, Consolidate, Modernize, or Retain, on evidence rather than politics.

One aligned KPI set

At a global workforce solutions firm, roughly 50 KPIs across sales, operations, delivery, and finance, cascaded from brand to market and delivered weekly in Tableau.

Governance that holds

Naming conventions, creation policy, and periodic access reviews so the sprawl does not simply grow back.

Beyond the build, I designed and facilitated training to guide leaders in using and interpreting the insights, and joined monthly performance meetings to support interpretation and continuous improvement.
How it works

The rationalization method

Optional deep-dive · six steps, collapsed. Expand any step for detail.
1Catalog every asset
MetadataData sourcesDependencies

Extract metadata, data sources, and dependencies across every BI platform, spreadsheet, and reporting tool, and map each report to a business owner, creator, and process group.

2Pull hard usage
Server logsExecution frequencyActive consumers

Pull server logs to capture actual execution frequency, unique views, and active consumer lists over the past 6 to 12 months. Evidence, not opinion.

3Assess relevance and overlap
Stakeholder interviewsDecisions vs habitMetric overlap

Interview stakeholders to separate reports that drive active decisions from legacy habit, and compare underlying metrics, filters, and dimensions to flag redundant or near-identical reports.

4Assign a disposition
RetireConsolidateModernizeRetain

Sort every report into one of four actions: Retire (no usage or duplicated), Consolidate (merge overlapping KPIs into one dashboard), Modernize (high value, needs an upgrade), or Retain (unique, high-frequency, business-critical).

5Build target state, validate parity
Semantic modelsOfficial dashboardsData parity

Rebuild consolidated semantic models and clean official dashboards on the primary platform, and validate new outputs against legacy for exact metric alignment before cutting access.

6Govern to stay clean
Creation policyNaming conventionsAccess reviews

Enforce strict creation policies, naming conventions, and periodic access reviews so the reporting clutter does not grow back.

Retire, consolidate, modernize, retain

Every report plotted by real usage against uniqueness and value, and auto-sorted into one of four dispositions. Filter by function and click any report for its usage, overlap, and recommended action. An interactive reconstruction.

The impact

Under 1,000 reports, and trust restored

Rationalization cut the Cognos footprint from more than 15,000 reports to under 1,000, anchored by roughly 50 aligned KPIs delivered weekly in Tableau to market and brand leadership. Business performance improved across several KPIs, including gross profit, and North America became the model for data-driven performance management. I ran a similar Workday-focused effort at a Fortune 25 health insurer, reducing about 1,400 reports to around 500.

The bigger win was cultural: a single, trusted source of truth rebuilt the analytics muscle, so leaders used the data to run the business instead of arguing about whose numbers were right.
