I run a company which develops medical devices, many of which combine mechanical, electronic and software engineering. It's well known (and a running joke) that software engineers from non-medical fields think it is acceptable to ship their product with serious defects. It takes a long time and a lot of training to get them up to the level that we need, more so than for mechies and sparkies.

Do you have any solid books etc for the kind of processes you use?

For software in medical devices, the process that's accepted by the regulatory authorities is ISO 62304 http://www.iso.org/iso/catalogue_detail.htm?csnumber=38421

That's a good start
