LI { margin-top: 6px; margin-bottom: 6px; } OK, let's just get this over with once and for all. Why haven't we joined Continua? And why did we move forward with a device strategy for HealthVault if we (raise one eyebrow here) aren't out to corner the world market on peak flow meters? Pardon the sarcasm, but jeez, give me a break.
HealthVault is about delivering and enabling solutions that improve real people's health. A big part of that vision is about care outside of traditional care settings --- at home, at the gym, at school, and so on. By now we all know the statistics about costs of chronic disease, and the incredible opportunity to save lives and money by keeping people out of acute care situations in the first place. Monitoring devices do and will play a huge part in a shift to preventative medicine - they are super-important. Getting started with solutions now is even more important.
Back when we started this project in 2006, some key leaders from the Windows for Portable Devices team (hey Oren, hey Bert) came to Health Solutions and said --- we built the WPD standard to support device classes beyond media players and cameras. We think it can apply to healthcare, and we want to make it happen. Seemed like a good idea, so off we went.
Now - a few months later, along comes Continua with a plan to create a bunch of new committees and new standards. No timeframe for delivering anything concrete, but a few rather unsettling terms in the invitation that they sent our way. I'm no lawyer, but here's what we saw when we read the bylaws:
Hmm. So the next step was to go back to our device team, who at this point already had code working and were engaged with a number of device manufacturers - many of them part of Continua - who felt that what we were doing with HealthVault made sense too. We got an education in the way that the WPD infrastructure really works. Because it is uses a "meta driver" model that can sit on top of any underlying transport, the team was confident that when the Continua standards did emerge, we would be able to layer in something called a "class driver" that would enable them to work with our existing system. And we also were reminded that WPD isn't bound to HealthVault at all - anybody can work with our devices on Windows without any HealthVault software at all - even Google and Dossia.
So, the choice before us was pretty simple. On the one hand, we could join Continua at great resource cost and limited influence, with an unspecified time horizon for getting solutions into the market. On the other, we could make devices available as quickly as possible, leveraging existing open standards, with the knowledge that when Continua devices became meaningful in the market we had a simple path to include them in our infrastructure as well.
A year later, with more than fifty devices in the market, and watching real people building real solutions on top of our infrastructure - I think we made the right choice. I'm
