I thought I had finished my Excel Data Analysis project
Dashboard done ✅ Pivot Tables done
✅ DAX measures done ✅
Then during my final review, I noticed a duplicate table in my data model and decided to delete it Big mistake What looked like a 30 sec cleanup turned into hrs
What was supposed to take 10 minutes ends up taking hours.
Today reminded me that Data Analytics isn't just about creating charts and dashboards. Sometimes the real work is finding those unusual values that can completely change your analysis if ignored.
Have you ever started working on a project and thought,
"Just one more step and I'm done." 😌
Then suddenly, one outlier shows up... 👀
You investigate it.
Then another one appears.
You check the formula
You review the data.
You question your life choices for a moment
