The Evolution Index (EI) Simulator Tool was built to help the client plan strategically by simulating various market growth scenarios across countries. Built in Power BI, the tool helps users to input key variables and dynamically evaluate their impact on year-end performance. This simulation-driven approach enhances forecasting accuracy and helps organizations allocate resources effectively, driving smarter business decisions and maximizing market opportunities.
The client faced challenges transitioning from free-form Excel models to a structured Power BI environment, encountering friction with inputs, scalability, and speed. Large parameter lists, precision requirements, and extensive country-level granularity highlighted tool limitations and slowed overall adoption.
Transitioning from Excel’s flexible inputs to Power BI’s more static interface created a barrier, especially for entering dynamic parameters like country-specific growth and allocations.
Power BI slicers sample values if more than 1000 rows exist. This led to rounding errors, making it difficult to capture precise input values necessary for accurate forecasting.
With many countries and multiple input parameters per country, the dashboard’s page load speed significantly slowed, impacting user experience during simulations.
To address Excel-to-Power BI migration issues, slicer limitations, and performance bottlenecks, NeenOpal implemented tailored design strategies. Parameter tables replaced Excel inputs, custom slicer logic ensured accurate selections, and performance trade-offs were accepted given the tool’s strategic use. These optimizations enabled a smooth, functional simulation experience within Power BI's framework.
Replacing Excel’s free-entry fields, parameter tables (ranging -100 to 400 with increment of 0.1) allowed users to input company/market growth and allocations through slicers. These tables fed into DAX measures using the minimum selected value.
Power BI’s 1000-value slicer limit was mitigated by using “greater than or equal to” logic to select precise user inputs despite data sampling limitations.
The dashboard’s slower load times due to multiple country-parameter combinations were acknowledged by the client as acceptable, given the tool’s limited usage throughout the year.
NeenOpal specializes in bridging data science with business strategy through innovative Power BI solutions. With a deep understanding of technical limitations and business expectations, we create customized tools that deliver insights, optimize decision-making, and scale with evolving client needs.
The project created a win-win outcome for both the client and NeenOpal, driving technical innovation while ensuring measurable business value. These benefits strengthened trust, efficiency, and strategic decision-making.
The EI Simulator empowered strategic planning with data-driven foresight, replacing static Excel sheets with a dynamic Power BI experience. Despite inherent limitations, NeenOpal’s tailored approach delivered lasting value, streamlining decisions, optimizing resources, and fostering smarter goal-setting across global markets.
