Here is a simple one page overview on segmentation that I find useful when trying to share this concept with others.
Here is an overview from New Product Blueprinting, tailored to B2B market research/new product development. An excellent how-to manual on developing breakthrough products for B2B markets, that gives step-by-step guidance.
And finally, here is a pretty useful and easy-to-understand overview of 3 main types of B2B segmentation:
- industry/firmographic (akin to demogrphaic segmentation for B2C markets)
- customer tiering (focusing in size of prize and fit of your value proposition)
- needs based (grouping by needs, however these companies will be across industries and appear very heterogeneous)
