There seems to be 3 major "IT" Treasury systems in use around the world.
1) Custom - custom developed software specifically designed for the country. This could include everything from mainframe legacy systems to more recent systems such as in several countries in latin America.
2) COTS - commercial vendor solutions, typically implemented by a consulting/systems integration company with some customizations to address government / customer specific requirements.
3) "Given" by another country. Examples include selected countries in Africa and Central/South America where a country gives its neighbor a copy of the system for their own usage.
There seems to be a growing emphasis on going COTS. Although the World Bank may not have an official preference, many PFM reforms appear to include an IT element that is based on upgrading the existing system (including manual systems) with a COTS based solution.
Has anyone noticed this trend declining? Maybe increasing? Perhaps a steady-state, neither growing nor shrinking.
