The document discusses model-driven software development (MDSD) and whether it is considered "hot" or useful. It notes that MDSD can help with decreasing time-to-market, increasing flexibility, and managing increasing complexity in projects. The company Sioux has investigated using MDSD in their in-house projects and remote solutions to see how applicable the approach is. Sioux also provides workshops to give a quick overview of MDSD and how it can be learned. The document promotes future "Hot or Not" events to discuss additional software development technologies and their usefulness.
