Sharing project files
For QDA software that is not cloud-based, you will need to develop a plan for sharing and merging project files.
Working on a cloud-based project
Some QDA programs have a cloud storage component that let you work with your team on the same online file. If you do use a cloud storage based program, keep in mind that this means putting your data online and you should ensure that this is done in way that meets the guidelines in your IRB protocol or other ethical expectations.
