Open Source's Position in the Spectrum of Software

To determine which parts of your product line or components of a given product to open-source, it may be helpful to conduct a simple exercise. First, draw a line representing a spectrum. On the left hand side, put ``Infrastructural,'' representing software that implements frameworks and platforms, all the way down to TCP/IP and the kernel and even hardware. On the right hand side, put ``End-user applications,'' representing the tools and applications that the average, non-technical user will use. Along this line, place dots representing, in relative terms, where you think each of the components of your product offering lie. From the above example, the GUI front-ends and administrative tools lie on the far right-hand side, while code that manages backups is off to the far left. Development libraries are somewhat to the right of center, while the core SQL facilities are somewhat to the left. Then, you may want to throw in your competitors' products as well, also separating them out by component, and if you're really creative, using a different color pen to distinguish the free offerings from the commercial offerings. What you are likely to find is that the free offerings tend to clump towards the left-hand side, and the commercial offerings towards the right.

Open-source software has tended to be slanted towards the infrastructural/back-end side of the software spectrum represented here. There are several reasons for this:

This is why we see solid open-source offerings in the operating system and network services space, but very few offerings in the desktop application space.

There are certainly counterexamples to this. A great example is the GIMP, or GNU Image Manipulation Program, an X11 program comparable in feature set to Adobe Photoshop. Yet in some ways, this product is also an ``infrastructure'' tool, a platform, since it owes its success to its wonderful plug-in architecture, and the dozens and dozens of plug-ins that have been developed that allow it to import and export many different file formats and which implement hundreds of filter effects.

Look again at the spectrum you've drawn out. At some point, you can look at your offering in the context of these competitors, and draw a vertical line. This line denotes the separation between what you open-source and what you may choose to keep proprietary. That line itself represents your true platform, your interface between the public code you're trying to establish as a standard on the left, and your private code you want to drive demand for on the right.
