Just used #Claude to help me clean up some of the #mapping syntax for scraping and analyzing #GoogleTrends data that I wrote a few years ago.
Now… let’s see if we can predict the results before today’s election in Tennessee!
Are you also a #map lover? Hope you enjoy this! 🗺️🚀

Deploying tools or KPIs is easy. We often rely on them to simplify the decision-making process. Are managers making good decisions? That is a business question. A tool, #dashboard, or #KPI should not be a substitute for aligning #data and people to work together effectively.
