Competitive intelligence - technical or not

What is the main differences between Competitive Intelligence (CI) and Competitive Technical Intelligence (CTI) ?

Competitive Technical Intelligence (CTI) -
Analysis and understanding of the external environment in context of internal business environment, with science and technology as added factors.

Tools and techniques will be different - more technical and specialized, definitely. Data collections and source will be different too. Then comes, communication and organizational culture, customers, and time horizon (definitely longer than CI since the entire product development cycle needs to be followed through).
