This year's Oscar nominees for best picture include four films based on true stories and each one has been criticized for factual inaccuracy. You might think: Does it really matter? Can't we keep the film world separate from the real world? Unfortunately, the answer is no. Our minds are well equipped to remember things that we see or hear but not to remember the source of those memories. Consider the following evolutionary story. If a hunter on the savanna approached a watering hole, being able to remember that there had been a lion attack at that hole could be a lifesaver. But retrieving the source of the memory (did my cousin tell me about it? or was it my brother?) was less critical. As a result, our brain's systems for source memory are not robust and are prone to failure.
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
