 Graphical interfaces in Supplier Performance Management Portal
AL SPM graphical enhancement project was executed for Ashok Leyland which implemented
graphical interfaces to analyze captured supplier metrics data and enable the AL Sourcing team
to take right business decisions. The graphical interface included Pareto charts to analyze the
top 20% supplier spends on the overall supplier business spends, spend performance analysis to
analyze spend vs. supplier performance and linear trend analysis to understand the future trend
of supplier metrics based on past data.
To be able to perform the same, database was designed to hold business data in de-normalized
form for better performance and the business logic to render the graphs were written in SQL
stored procedures. The supplier data which was available from AL ERP database was parsed,
analyzed and performance data were calculated. It involved writing a few SQL functions to
calculate the cumulative spend value and cumulative spend percentage for generation of Pareto
charts.
• Performed database design related to changes in the existing Portal.
