The value of a solution cartography in IT portfolio management

0/5 | 0 votes |

This document describes the problems that many organisations and public administrations have related to the creation and maintenance of their solution cartography (a map of existing (IT-) solutions of an organisation, their characteristics and the connections between the different solutions). It describes the relation to application portfolio management, project portfolio management and IT portfolio management and gives a conclusion on the added value of a solution cartography in IT portfolio management. This document also provides information on the support that is given by ISA² in the form of the European Interoperability Reference Architecture (EIRA) and the Cartography Tool (CarTool).


This document is targeted at Portfolio managers with a strong interest in Enterprise Architecture and Enterprise Architects that are interested in IT Portfolio Management and what the added value of a solution cartography in this domain is.
The annexes contain references to other frameworks like IT4IT® (which heavily relies on Porters Value Chain), COBIT®, ITIL™, TOGAF® and Zachman Framework™ (Zachman International®), for which only a brief introduction is given, prior knowledge of those frameworks will help the reader better understand those annexes.
