Where revenue grows. Where margin slips.

Project overview

This is a demonstration case study for the website layout. It is not a completed project or a claim about Adekunle’s results.

A fictional retailer wants to understand why increased sales may not produce stronger margins.

Compare sales and margin by product group, examine discount patterns and propose questions for further investigation.

Synthetic figures created for illustration. No client data or real commercial results are represented.

Power BI for the proposed dashboard; SQL for the proposed preparation and aggregation workflow.

The example workflow checks missing values, inconsistent product labels, duplicated transactions and valid dates before aggregation.

Compare revenue, gross profit and discount rates across products and periods. Separate observed associations from causal claims.

The illustration shows the type of overview a dashboard could provide. Its figures are synthetic.

An increase in sales alone does not establish an improvement in business performance. Margin and returns provide additional context.

Review discounts by category, agree consistent definitions of gross margin and investigate changes using transaction-level evidence.

No measured business impact is claimed. Replace this section with supported outcomes from a real project.

Comparable periods and consistent metric definitions are needed before drawing conclusions.

This sample demonstrates where project-specific reflection will appear. Adekunle’s own reflection is still required.
