What would your event cost? How would you pay for it?
You must produce a spreadsheet model so that you can work out costs, decide how much to charge, how many tickets you would need to sell, etc.
Your model will be used by the team to help decide which event to hold.
Produce your spreadsheet model using this design to help you. Make sure that it is easy for other team members to use
Test your model to make sure that the formulae are correct and it is easy to use.
Pass the spreadsheet to your team and ask them for comments. Make changes where necessary. Help the others by giving them feedback on their models.
Save evidence of your spreadsheet model in both value and formulae views for your eportfolio.
Update your project diary. Include comments you received about your model and feedback you gave to other team members.
