28. End-to-End Project: Blinkit Quick-Commerce Dashboard
28.8 Step 7 – Check Performance and Quality
- Run Performance Analyzer; fix any visual that is much slower than the rest.
- Verify numbers: Total Orders in a card should match the count of distinct Order IDs in the raw files (check with Excel or SQL).
- Check blank rows in slicers (these indicate missing keys between fact and dimension).
- Confirm that Blinkit Orders + Amazon Now Orders = Total Orders.
- Spell-check titles; consistent formatting; hide helper tables and tooltip pages.
Ravindra Bagale's Tip
Friends, many students skip the quality check because the report "looks right". Run Performance Analyzer, test every slicer and drill path, verify three or four key numbers against the source, and ask one classmate to use the report without help. It's very simple – just make it a habit.

मित्रांनो, report "बरोबर दिसतो" म्हणून बरेच students quality check वगळतात. Performance Analyzer चालवा, प्रत्येक slicer आणि drill path test करा, तीन-चार मुख्य numbers source शी जुळवा, आणि एका classmate ला मदतीशिवाय report वापरायला सांगा. एकदम simple आहे, फक्त सवय लावून घ्या.

दोस्तों, report "सही दिखती है" इसलिए बहुत से students quality check छोड़ देते हैं. Performance Analyzer चलाओ, हर slicer और drill path test करो, तीन-चार मुख्य numbers को source से मिलाओ, और एक classmate से बिना मदद के report इस्तेमाल करने को कहो. बहुत आसान है, बस आदत बना लो.
