Hi Dan - You are absolutely correct that describing new products as creating a chasm is a major overstatement in many cases where evolutionary technology is being offered. The one thing smaller and bigger chasms have in common for the startups offering the new technology is the need to find an early adopter, a risk taker. This type of person can be hard to find and is required tfor the adoption of new technology.
A common misconception is that all new prodcts follow the chasm model, however only distruptive products fit the chasm model. Most new EDA tools are not disruptive, rather they are "me too" or incremental products in predfined segements, so they don't really follow the chasm model. Trying to apply the chasm model to a Schematic Capture or Logic Synthesis tool in a mature market segment will not make sense.
