27% Leaner Reporting After 8-Week Tableau to Sigma Migration
Aimpoint Digital helped a life sciences technology company migrate from Tableau to Sigma in just 8 weeks, consolidating 81 dashboard views into 59 across five business divisions while equipping internal champions to build and expand reporting independently.
The Challenge
A life sciences technology company that builds CRM and cloud software for the pharmaceutical industry needed to migrate from Tableau to Sigma after a strategic decision to move away from Salesforce-ecosystem products. Leadership set a firm deadline: critical reporting had to be live on Sigma before the broader platform cutover in the fall.
Although the company had selected Sigma as its future BI platform and had already begun migrating underlying data models to Databricks, it lacked the internal Sigma expertise and bandwidth required to execute the Tableau migration alongside ongoing operations.
The effort was further complicated by undocumented Tableau workbooks. Many original builders had left the organization, and the remaining team couldn't fully explain the logic behind key reports.
The company needed a partner who could reverse-engineer undocumented workbooks, execute the migration quickly, and do it across five distinct business divisions: FP&A, Sales, Marketing, Facilities, and Product Support.
Our Approach
Aimpoint Digital deployed a team of Sigma and Tableau experts, organizing the migration by business division to ensure each area received focused attention.
Division-Aligned Delivery
A team of dedicated Aimpoint consultants supported the five divisions in scope (FP&A, Sales, Marketing, Facilities, and Product Support). Our team partnered directly with a designated subject matter expert on the client side, creating tight feedback loops that accelerated understanding of report logic and business context.
Reverse Engineering Without Documentation
With no formal documentation available for many Tableau workbooks, the Aimpoint team systematically deconstructed existing reports to understand their underlying logic, data sources, and business purpose before rebuilding them in Sigma. This required deep expertise in both platforms and close collaboration with division SMEs who understood how reports were used, even when they couldn't explain how they were built.
Consolidation and Optimization
Rather than performing a one-to-one lift-and-shift, Aimpoint Digital identified opportunities to consolidate redundant reporting. In several cases, five separate Tableau dashboards were reduced to a single Sigma workbook tab using native filtering and interactivity features. This reduced maintenance overhead and gave end users a cleaner, more flexible reporting experience.
Navigating Data Dependencies
Development timelines were managed around dependencies on the client team responsible for the Databricks migration. Aimpoint structured work to maximize productivity during periods of data availability and shifted focus to workbook design and stakeholder alignment when data access was limited.
Results
The Aimpoint team migrated 59 Tableau dashboard views to Sigma across five business divisions within an 8-week timeline, meeting the leadership-mandated deadline for the broader platform cutover. Critical reporting was live and validated in Sigma before the fall transition, ensuring zero disruption to business operations.
By identifying overlapping and underused reports during the migration process, the team reduced the total reporting footprint rather than inflating it. Aimpoint consolidated 81 Tableau dashboard views into 59 Sigma workbook views, a 27% reduction in report volume. Multiple Tableau dashboards were consolidated into single Sigma workbooks using native interactivity features, cutting maintenance overhead, and giving users a streamlined experience. The legacy Tableau platform was fully retired after migration.
The engagement extended beyond the initial migration into co-development and training phases. Aimpoint worked alongside a client Sigma champion through shadowing sessions and paired building, transferring skills that allowed the champion to independently build an entire suite of workbooks for the Services division. Follow-on phases included training workshops, office hours, and Sigma best practices sessions that expanded the company's internal capabilities.
Key Takeaways
Dashboard migrations that stick aren't about moving files from one platform to another. They require deep understanding of the business logic behind existing reports, especially when documentation doesn't exist and original builders have moved on.
Aimpoint Digital's division-aligned delivery model and reverse-engineering approach allowed the team to migrate 59 dashboards in 8 weeks while reducing report redundancy. The phased engagement structure, which moved from migration to co-development to training, ensured the client's team could maintain and expand their Sigma environment independently after Aimpoint's involvement ended.
The three-phase arc of this engagement (migrate, co-build, train) has since become a model for how Aimpoint Digital approaches dashboard migration programs where long-term client independence is the goal.
