How to develop a smartphone App to be FDA-cleared or CE Marked? - part 2 IEC 62304 and agile methods

In the last article we've seen the consequences of regulations on Apps, which run on smartphone or - more broadly - on mobile platforms.
Today, let's have a look at the main standard to apply when developing software for medical devices: IEC 62304, and the context in which most people want to apply it: agile methods.

What is software verification?

Many people make the confusion between verification and validation. There is no exception for software! I'd even say that the confusion is even worse for standalone software.

Let's see first the definition of verification and validation. I borrowed these definitions from the FDA website:

  • Verification is confirming that design output meets the design input requirements,
  • Validation is ensuring that the device conforms to defined user needs and intended uses.

OK, this remains theoretical. How to do that with software medical devices?
In this article I focus on verification and will focus on validation in the next article: What is software validation.

How to use templates with agile methods?

All templates I have written are listed in my templates repository page. I already explained in that page and some other articles how to use them with waterfall development process.
But their use is not obvious with agile methods. Here are a few explanations.

Class C software and agile methods

Are agile methods compatible with the constraints of development set by IEC 62304 standard of class C software?
After a series of three posts about agile methods and risks analysis. I focus in this post on IEC 62304 class C critical software.

How to combine risk management process with agile software development? - Part 3

We've seen in my last post that it's possible to have agile development methods combined with a risk management process. To be compliant with ISO 14971 standard, a risk management plan that describes this process along iterations, has to be written. And a risk assessment report has to be created in iteration 0 and updated in every iteration, by following the risk management process like the one found in figure 1 or figure B.1 of ISO 14971 standard.

How to combine risk management process with agile software development? - Part 2

This post is the continuation of the post of last week.
We've seen in that post that fixing bugs during software maintenance is like a small chunk of design, excepted that software specifications do not change. Therefore risk management process when fixing bugs is very close to risk management process during design, without the initial assessment of risks at the beginning of the software development cycle.

How to combine risk management process with agile software development? - Part 1

This post comes after a series of three posts where I exposed my thoughts about development of software medical devices with agile methods.
These posts were focussed on software development. Risk management deserves its own series of posts. Here is the first of three.

How to develop medical device software with agile methods? - Part 2

In my previous post, I explained how I tweaked the waterfall model to obtain something close to agile methods. But still not agile, actually...

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!
