AstraZeneca is a global biopharmaceutical firm that develops, researches, and sells medicines in different countries. The company's headquarters are in Cambridge, and regional offices are located in different nations. AstraZeneca has partnered with Code1 to onboard IT experts for assistance in their Power BI development project.
The foremost challenge was the scattered data as the client was using multiple sources like CRM platforms, ERP systems, and third-party databases to store their information. So, it was a tedious task to unify the diverse data sources in a centralized system without compromising accuracy and consistency
The client had different user roles in their internal hierarchy which had different data access levels. So, it was a challenging task to implement object-level security, and row-level security (RLS) to ensure that the access of confidential data is limited to core stakeholders and management board.
Our client was focused on building a solution that can perform advanced calculations like custom KPI calculation and forecasting, year-over-year growth forecasting, etc. So, complex data analysis expressions (DAX) formulae have to be used to achieve the expected outcomes.
To mitigate the first challenge, our experts deployed the ETL (extract, transform, load) technique using Azure Data Factory and Power Query. It helped significantly the team in cleaning, unifying, and transforming the data into a single Power BI model.
It was important to control the data access within the enterprise and thus we fostered Object-Level Security and Row-Level Security to restrict the user access based on their managerial position. It helped us to ensure that only authorized stakeholders could access confidential information.
To impart the advanced calculation capabilities in the Power BI solution, we optimized the DAX formula by using different practices like calculated columns, leveraging variables, and using measure units. Our expert helped to pre-aggregate data to reduce overall calculation complexities.
The development team conducted the post-deployment workshops in which all the internal and external stakeholders of the company were offered adequate training. The workshops ensured that employees could leverage the full potential of the Power BI solution from the first day.
The seamless implementation of the Power BI solution encourages enhanced decision-making.
