Integration is largely dismissed by those interested in purchasing software these days. Quotes like “don’t worry, we’ll make it happen” or “oh, it’ll all come together in the end” are heard in meetings as everyone rushes to sign the vendor’s contracts before the end of the fiscal year. Unfortunately, six months later the same people are saying “the vendors weren’t upfront in their demos with us!” and “I don’t understand what’s so difficult about all this, why can’t they just make it work!”.
If you’ve ever integrated different systems together, you know that integration is where the rubber meets the road so to speak. From a technical perspective, I’m not a fan of bolting two (or more) different systems onto each other and forcing them to talk to one another. However, many times it has to be done and if that’s the case, it needs to be planned accordingly. The best way I can explain an integration effort is this:
System 1, a.k.a. “Worf”: A Klingon who hails from the planet Kronos. Worf has been characterized as a “swarthy humanoid”, doesn’t like cold weather and enjoys a bloody battle. Speaks Klingon.
System 2 a.k.a. “Enel”: An Elf who hails from Valinor in Middle-earth. Wise and immortal, Enel is a skilled hunter and has pledged to preserve the world. Speaks Elvish.
Worf and Enel couldn’t be more different. In fact, they’re completely different in every way imaginable. So, how the heck do you make them talk to one another? Hire an interpreter (i.e. 3rd party software tool) to assist in the language barrier? What similarities does Worf have that Enel can understand (i.e. temporary tables)? What symbol of understanding can be passed between them (i.e. Web Services or APIs)?
To ensure that the Klingons don’t invade the Elven continent of Middle-earth and destroy an ancient civilization, it’s important that you get your Supreme Council in a room (i.e. project stakeholders) along with your Trusted Advisors (i.e. IT architects, etc.) and determine the best way (or ways) for Worf and Enel to communicate with one another before you join their people together as a nation. Otherwise, prepare for Worf’s battle cruiser to enter Middle-earth airspace and it won’t be pretty.
