We're used to hearing of software being described as "free as in freedom" and "free as in beer." But there's another kind of "free" that doesn't get talked about as much: "free as in puppy." This concept is based around the idea thatwhensomeone gives you a free puppy, that puppy isn't really free. There's a lot of work and expenses that go into its daily care. The business term is "total cost of ownership," or TCO,and it applies to anything, not just open source software and puppies.

So if the free puppy problem applies to everything, how is it important to open source software specifically? There are a few ways. First, if you're already paying for software, then you've set the expectation that it has costs. Software that's free up front but costs money later seems like a major imposition. Secondly, if it happens on an organization's first open source adoption project, it can put the organization off of adopting open source software in the future. Lastly and counterintuitively, showing that open source software has a cost may make it an easier "sell." If it's truly no cost, it seems too good to be true.

The following sections represent common areas for software costs to sneak in. This is by no means a comprehensive list.

To begin using software, you must first have the software.

Getting the software installed is the easy part. Now you have to use it.

Even with a list like this, it takes a lot of imagination to come up with all of the costs. Getting the values right requires some experience and a lot of good guessing, but just going through the process helps make it more clear. Much like with a puppy, if you know what you're getting yourself into up front, it can be a rewarding experience.
