Dashboard and presentation


hello Community,

i have been using smartsheet for a month now and I have a presentation tomorrow with the top management and the client.

The schedule has many items, and I was wondering how to make a successful presentation or a dashboard tomorrow and visualize the data, the main items are regarding hiring, training, contracts, percentage as well as assigned persons, schedule status. I have made some equations but still can't calculate the accurate percentage for hiring and training as they are not listed in order but divided by departments.

and I see the dashboard I have made is poor.

any help?

thanks in advance.
