POLDAT is an architectural unification approach to recognize the commonalities between the radical re-engineering, Enterprise Transformation Planning and IS Planning. It dates to Catalyst Release 3 in the early 1990s and was one of the earliest integrated Enterprise methodologies. It is also embedded in Casewise's Corporate Modeler, an early partner in providing automated support to Catalyst in the mid 1990s. This and some other factors has contributed to the POLDAT framework being slightly more prevalent in Europe. References
