- Value trees usefulness in assessment of enterprise architectures valuePublication . Rodrigues, Luis Silva; Amaral, LuisIn last two decades a significant number of organizations began to build Enterprise Architectures in order to deal with complexity and change, to align business and IT, to cut costs and several other objectives. The current economic pressures and the significant investment that Enterprise Architectures represents are increasingly demanding an assessment and demonstration of their usefulness and value. Despite the need and interest there still is no consensus on how to demonstrate the value. Some value models and methods have already been presented but they are still not detailed enough to be used and require further research to be useful for most organizations. In this paper, we present an initial discussion about the usefulness of value drivers and value trees as a way to measure the Enterprise Architectures value.
- Multidimensional value of enterprise architecturesPublication . Rodrigues, Luis Silva; Amaral, LuisThe increasing complexity of organizations and the environment around them are increasingly demanding for a better and deeper knowledge about how to organize and use IT in order to fulfil the organizations mission, strategies and goals. In the past two decades, in order to obtain a description of the current IT and business state and/or to establish the desired future state, a significant number of organizations began to build Enterprise Architectures. Despite the efforts done, the resources spent and the benefits expected practitioners and researchers recognize that it is still difficult for organizations to assess and measure the Enterprise Architecture value, given the process complexity and the nature of some value factors. In this paper a multidimensional value approach is presented, that considers four value dimensions in Enterprise Architectures value analysis: strategic value, operational value, user value and economic/financial value.
