About Client

  • A global leader in technology consulting services and digital transformation solutions.
  • Actively operating in 50+ countries and with a workforce of over 350,000 professionals, this esteemed collaboration was executed as part of our client’s engagement with a leading automotive client.

Problem STATEMENT

The client struggled to deliver consistent, timely, and actionable reporting across business units. Key challenges discussed:

Scattered Metrics

KPIs were maintained in separate Excel sheets, resulting in inconsistent formats and metrics across teams.

Slow Decision Cycles

Manual consolidation of data caused delays, making it hard to act on insights quickly.

Limited System Integration

Existing reports weren’t connected to enterprise data sources like ET2000 and DMS, restricting scalability and broader analysis.

Isolated Data Stack

Sales, inventory, and retail performance data remained isolated, preventing cross-functional visibility.

Static Reporting

Reports lacked interactivity, no drill-downs, filters, or real-time updates, reducing their usefulness for operational decision-making.

Solution

Upon further discussions, DataToBiz implemented a comprehensive two-phase BI transformation workflow: 

Phase 1: Rapid Excel-to-Power BI Development

  • Developed 20 Power BI dashboards covering ~80–90 KPIs, including accessory sales, dealer inventory, kit penetration, WIP, license payouts, and retail performance. 
  • Standardized Excel files and migrated KPIs into interactive dashboards with drill-downs, slicers, and DAX-based calculations for immediate visibility. 
  • Implemented role-based access to secure reporting and control visibility across teams. 
  • Created a centralized reporting framework with standardized KPI definitions to ensure consistency across all business units.

Phase 2: AWS Data Warehouse Integration

  • Migrated reporting from Excel to automated, AWS-powered data pipelines, connecting Power BI to ET2000 (~50K rows/day) and DMS (~20K rows/day) via S3, Glue, and Athena. 
  • Configured automated daily data refreshes and optimized query performance for near real-time reporting. 
  • Extended dashboards to include additional complex KPIs and implemented archival processes for historical trend analysis.
  • Delivered complete artefact handover, UAT support, and training to empower the internal team to manage and maintain the solution independently.

Phase 2:

Building a Scalable

 

Architecture & Data Integration

  • Phase 1: Power BI connected to standardized Excel datasets.
  • Phase 2: Direct Athena connection to AWS Data Warehouse; optimized Glue jobs for pipeline efficiency.

Dashboard Development

  • Wireframed 20 dashboards covering ~90 KPIs.
  • Built using Power BI with DAX measures, filters, and drill-throughs.
  • Role-based workspaces for secure access.

Data Automation

  • Daily refresh schedules aligned with continuous business cycles.
  • Archival in AWS for multi-year trend analysis.

Performance Optimization

  • Query tuning in Athena and DAX model optimization.
  • Implemented incremental refresh for large datasets.

Business Impact

Faster Report Preparation

Automating Excel-based processes with AWS-powered pipelines cut report preparation time by ~50%, reducing manual effort from 8-10 hours per day to just 4-5 hours.

Real-Time Decision Making

Daily refreshed dashboards provided leaders with near real-time insights, improving decision-making speed by approximately 40%.

Consistent KPI Tracking

Standardized metrics and centralized dashboards ensured 100% alignment of KPIs across 6+ business units, reducing discrepancies and reporting errors by around 35%.

Scalability

AWS integration allowed the platform to handle 2-3x data growth without performance degradation, supporting future expansion to additional regions and datasets.

Improved Data Governance

Role-based access, standardized definitions, and audit trails covering 100% of dashboards and datasets strengthened governance, cutting compliance risks by roughly 30%.

By connecting Power BI with AWS data pipelines, DataToBiz helped the client shift from static, disconnected reports to a centralized, automated, and interactive BI system. This improved efficiency, cut reporting delays, and created a scalable analytics foundation for smarter, long-term decisions.

Frequently Asked Questions(FAQs)

How do I know if a solution like this is right for my business?

A solution like this is a good fit if your teams spend more time collecting and reconciling data than acting on it, if reports from different departments do not match, or if decisions depend on delayed or manual reporting. It also fits when your data is growing in volume or sources, and your current setup struggles to keep up.

DataToBiz starts with a discovery call to review your goals, data sources, and reporting gaps. You get a clear view of the expected outcomes, effort, and timeline before any commitment.

Can DataToBiz customize the solution for my industry and current data setup?

Yes. Every solution DataToBiz delivers is configured around your industry, business processes, and existing data environment. The team assesses your current systems, data quality, and reporting needs first, then designs a solution that works with what you already have instead of replacing it. This applies across industries such as manufacturing, retail, healthcare, finance, and logistics, and across setups ranging from legacy databases to cloud data platforms.

Which tools, platforms, and data sources does DataToBiz work with?

DataToBiz works across the major analytics, cloud, and data engineering stacks. For BI and visualization, this includes Power BI, Tableau, and Looker. For cloud platforms, it includes Microsoft Azure, AWS, and Google Cloud. For data warehousing and processing, it includes Snowflake, Databricks, and SQL-based databases. Data sources include ERP and CRM systems, spreadsheets, APIs, IoT and sensor data, and third-party applications.

If your stack includes a tool not listed here, the team can assess compatibility during discovery.

How long does a project like this take with DataToBiz?

Most projects with DataToBiz take from a few weeks to a few months. The timeline depends on how ready your data infrastructure is for the initiative and how many systems need to connect. Smaller solutions go live quickly, while larger programs roll out in phases so you see value early. After an initial discovery call, you receive a timeline with clear milestones.

How does DataToBiz keep my data secure and compliant during the entire engagement?

Security and governance is part of the plan from the first conversation. DataToBiz works within your security policies and follows the regulations that apply to your industry. The project usually Access stays limited to the people who need it, and confidentiality terms cover the engagement from kickoff to handover.

What support and results can I expect after the solution goes live?

The work does not stop at go-live. Your team gets a proper handover and guidance on using the solution, and DataToBiz stays available for questions and improvements. The business impact of the project is measured against the goals set at the start, so you can see exactly what changed for your company.
