Why consider reverse-engineering? Lack of accurate specs

If you’ve worked on an interfacing team or for HIE, one of the issues you’ll hear about is a lack of accurate interface specifications. For instance, the vendor spec might be missing. Or the source or destination spec on hand might no longer match the production version.

So what do you do?

Lack of specs: what’s the impact on your ability to deliver?

By | Published: November 1st, 2011

When it comes to interface documentation formats, we’re all about using whatever analysts, project managers, and developers find helpful: Word site surveys, Excel lists, wikis, whatever works. Those tools are perfect for handling the baseline information around inbound and outbound channel specifications and transport specifics.

In recent customer conversations and in discussions on LinkedIn, one practice stood out: the use of sample messages to understand real-world systems. Sample messages contain a wealth of information about the systems that need to connect. [...]

Will HL7 V3 Adoption Take Off in 2011? 5 Points and 1 Caveat

By | Published: January 4th, 2011

A few weeks ago, I was working on an HL7 v3 project with an outside partner and the discussion turned to market adoption. We came to the conclusion that it’s not exactly taking off — at least, not as quickly as you might expect. Apart from meaningful-use initiatives around CDA in the US and the big push by Canada Health Infoway, I don’t really see much traction in North America. I’m going to come right out and say this: from [...]
