Benedict Evans has a phenomenal post up on his blog where he discusses the future of LinkedIn. Go read it, it’s excellent. In it he talks about the law of bundling and subsequent unbundling of web services. He uses Andrew Parker's brilliant image below to illustrate the point.

Craigslist came along and bundled everything into one place and, as a result, completely dominated. They destroyed multiple businesses in the process (including the rental and roommate web service I worked with just after college). They were immensely successful.

But now we're seeing the unbundling of Craigslist. Small players are coming in and biting off small pieces of their business and providing superior value. AirBnB does room rentals better than Craigslist, StubHub is a better ticket reselling service, LegalZoom is a better place to find legal services, etc.

Craigslist detractors believe that this will be death by 1,000 cuts.

Craigslist isn't alone. This is exactly what Facebook has been going through over the last several years: Twitter is attacking the status update, Foursquare is attacking the location feature, Instagram is attacking photo sharing (so much so that Facebook was forced to buy them), Vimeo is attacking video sharing, etc.

Of course, while unbundling is bad for the bundler, it’s great for the consumer. Consumers get more value, more features and easier to use web services.

When I saw the Craigslist image I couldn't help but think of the large EMR (Electronic Medical Record) companies -- Epic Systems, Cerner, Athena, Allscripts, etc. These companies have provided immense value by bundling and integrating a massive amount of clinical data with a nearly endless variety of healthcare related software services. They manage ambulatory clinical data, inpatient clinical data, practice management, patient communication, prescription filling, patient scheduling, billing, meaningful use compliance, population health, specialist referrals, patient engagement, risk management and many other things under the same platform. And just like Craigslist and Facebook, they've benefited hugely as a result.

But you can begin to see some cracks in their armor. As clinical data moves to the cloud, more and more startups are coming along and biting off small pieces of the EMR business and providing better value. This is the beginning of the unbundling of the big EMRs.

That said, what's easy to do in b2c software isn't so easy in b2b software. There are significant switching costs associated with switching health IT vendors and most hospitals and health systems are very risk averse and will take their time adopting new technologies (it's much easier for an individual to buy a ticket on StubHub than it is for a hospital to buy a new patient portal).

But with the dollars that are flowing into healthcare focused venture capital and the excitement around those investments, it’s only a matter of time before we see this unbundling accelerate and see more value flowing to providers and patients. And that's a good thing for our healthcare system.
