There is a wide belief that creativity is like rolling a dice, or a strike of lightning — that ‘Eureka!’ moment. While it is quite true that many of the ideas and solutions we come up with, generally comes from intuition and inspiration, but it is also true that this ‘intuition’ is based on a intricately structured system inside our heads. So, instead of telling why it is important to keep exposing ourselves to new inspirations and wait for that ‘Aha!’ to dawn on us, let’s take a contrarian route and deluge ourselves into something about systematic creativity.
Around late 1940s, a Soviet engineer and researcher named Genrich Altshulle, and his colleagues developed a methodology called TRIZ (Teoriya Resheniya Izobretatelskikh Zadatch; Russian) which means “The Theory of Inventor’s Problem Solving.” It systematically drives problem solving through processes and framework, along with its 40 principles of invention.
It is widely adopted by Fortune 500 companies, mostly in manufacturing business like BAE Systems, CSC, Procter & Gamble, Ford Motor Company, Boeing, Philips Semiconductors, Samsung, LG Electronics, but let’s not get into too much detail about TRIZ itself. Instead, I want to focus on the 40 principles of invention, and perhaps run a few articles on these principles.

First of them is Segmentation: Asking the question of ‘What if we segment this?’
We can segment something by dividing it into independent subsystems and making it more modular. As a programmer, we do this everyday. I’m sure there are still arguments about efficiency and effectiveness besieging this, but the whole concept of ‘object-oriented’ programming, decoupling, plugins, and alike are basically process of segmentation. When something becomes too complex and monolithic, it becomes unmanageable, the progress becomes sluggish, project renders itself inert.
Take a look at the excavator below:

As you know, excavators basically dig, and when they keep digging hard surfaces, teeth worn out pretty easily. Older generation of models had teeth molded together into one single tooth, which brought out a lot of waste during replacement. Engineers thought through this problem and came up with segmented teeth as you can see in the picture above.
Conceptually, marketers do this as well. The STP method in marketing starts by segmenting the market, targeting it, then positioning in the market. Although we can simply just yell to everyone about the product, which is basically what the first generation of web advertisement banners were doing, we can segment the market (by demographics, user behavior, etc.) and increase efficiency and effectiveness all together.
People often apply segmentation without thinking about it, but it often comes in handy to explicitly search for solutions by systematically sorting through possible approaches.
