||What's the right sample size for a software beta test?

I've been asked to helm the user research portion of a very large SaaS product's two month beta test this summer. The end users are higher ed instructors from a variety of different schools in the US. How many participants should I plan on recruiting to test with and collect qual/quant data from? Would 40-50 be okay? Numbers are up to me and budget isn't an issue, just my bandwidth.posted by The Adventure BeginstoTechnologyat 5:18 PM -7 answers
