When writing up his researches on electrochemistry, Faraday was faced with a difficulty: he was trying to describe physical processes that nobody had described, or perhaps even though of, before. As his ideas grew, language itself became part of his thinking. He sought precision and faced a particular problem with words that were in common use but had misleading theoretical connotations; the prime example was current, which implied that electricity was a fluid. New words were needed not for their own sake but because existing ones carried theoretical baggage that could constrain one’s thinking.

The building blocks required to achieve success in a business domain and differentiate the company from its competitors: Core domains : The interesting problems. These are the in-house activities the company is performing differently from its competitors and from which it gains its competitive advantage. Generic domains : The solved problems. These are the things all companies are doing in the same way. There is no room or need for innovation here; rather than creating in-house implementations, it’s more cost-effective to adopt \ buy existing solutions. Supporting domains: The problems with obvious solutions. These are the activities the company likely has to implement in-house or outsourced, but that do not provide any competitive advantage. Domain experts are subject matter experts who know all the intricacies of the business that we are going to model and implement in code. In other words, domain experts are knowledge authorities in the software’s business domain. T
