Various rumors began to reach us. The facts were generally known, more or less, but it was obvious that apart from the facts there were certain ideas accompanying them, and, most importantly, a great number of them.

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.

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.
