Please help me to understand what my PM means when she says the back translation for my translation into Swedish of the word “usability” was “usefulness”, which is a different thing.

What is the difference between “usability” and “usefulness”?

See the context below.


“You are asked to take part in this research study intended to investigate the safety, ***usability*** and performance of a surgical sealant developed to reduce the risk of leakage from the colon connection (“anastomosis”). Before you make a decision about participating in the trial, it is important that you are informed why the trial is being performed, what participating means for you, any possible risks or discomfort which may arise, and that you receive answers to any questions that you might have.”
