The Fixed Period has been so far discussed as to make it almost unnecessary for me to explain its tenets, though its advantages may require a few words of argument in a world that is at present dead to its charms. It consists altogether of the abolition of the miseries, weakness, and fainéant imbecility of old age, by the prearranged ceasing to live of those who would otherwise become old. Need I explain how extreme are those sufferings, and how great the costliness of that old age which is unable in any degree to supply its own wants? Such old age should not be allowed to be. This should be prevented, in the interests both of the young and of those who do become old when obliged to linger on after their “period” of work is over. Oh, it is an adamantine law to protect the human race from the imbecility, the weakness, the discontent, and the extravagance of old age! [Anthony Trollope (1882), The Fixed Period]
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
