How to develop medical device software with agile methods? - Part 1

IEC 62304 is the standard to apply for software in medical devices. It is not bound to any software development method or model. Though not explicit, using the waterfall development model is the most straighforward way to apply this standard.
The waterfall model has become old fashioned to the eyes of most of software developers, with the emergence of agile methods. Agile methods are so popular now that everydody wonders how to apply IEC 62304 with agile methods.

An AAMI/CDV-1 TIR(SW1) - Guidance on the use of agile practices in the development of medical device software exists about this subject. But it is still a draft and only members of AAMI have access to it.

So, how to use agile methods and still be compliant with IEC 62304?
Here are my thoughts about these questionings!

How to externalize software development for a medical device?

Case example

Your competitors are doing it and you customers want them. “Smart” means something like an tiny computer (its amazing how small they are), with an operating system and big software. For electronic stuff, you have your own engineers or you have your subcontractors, which you have been working for 20 years with. They knew how to design embedded software on microchips. But they don’t know how to design software of higher level, with intelligent behaviour and complex algorithms.
