What I Learned
Technical and practical lessons from the project
Think from the user’s perspective
Dashboard users need clarity first
A dashboard should make information easier to understand, not just more colorful.
Structure matters
Clean organization improves reporting
A well-organized workbook makes dashboard building and future updates easier.
Visuals should answer questions
Every chart needs a purpose
Charts are useful when they help users compare, detect trends, or understand performance quickly.
Publishing improves credibility
Projects should be easy to access
Sharing the PDF, Excel file, and repository makes the project easier for recruiters and clients to review.
