It's best to create this assumptions map as a shared spreadsheet, such as
Google Sheets, which is constantly updated and monitored regularly.
Status
Set the statuses as follows:
◾ When a new assumption is created, the status will be New.
◾ Members can change the status to In Progress when they are working on an assumption.
◾ When the assumption is proven true, they would change the status to Validated.
◾ When the assumption is proven false, they would change the status to Disproved.
