It would be great if we had puzzles based on data that children and also adults could solve.
For example, I came up with one of the data puzzles on my birthday and sent it out to relevant employees. To solve the puzzle they had to carry out data analysis across multiple business areas. My idea was to increase awareness about various domain data available in the data warehouse and in the BI reporting and analytics platform. The final result would equal my age (this was birthday special, but I didn't give any additional hint except for sending the puzzle and sweets at my desk email together). If you are a data analyst / BI professional, give this a try.
