“…In order to meet the green requests, other indicators have been recently defined to express the energy efficiency and not only the performance of a system or organization. These indicators can be referred in the state of the art with the names of Green Performance Indicators (GPIs) 32 or Key Ecological Indicators (KEIs) 33 with the purpose of measuring the environmental impact of a monitored system, process or activity.

Received (Day Month Year) Revised (Day Month Year)Concerns about energy and sustainability are growing everyday involving a wide range of fields. Even Information Systems are being influenced by the issue of reducing pollution and energy consumption and new fields are rising dealing with this topic. One of these fields is Green IT, which deals with energy efficiency with a focus on IT. Researchers have faced this problem according to several points of view. The purpose of this paper is to understand the trends and the future development of Green IT by analyzing the state of the art and classifying existing approaches to understand which are the components that have an impact on energy efficiency in Information Systems and how this impact can be reduced. At first, we explore some guidelines that can help to understand the efficiency level of an organization and of an Information System. Then we discuss measurement and estimation of energy efficiency and identify which are the components that mainly contribute to energy waste and how it is possible to improve energy efficiency, both at the hardware and at the software level.

“…33 refers to a set of indicators used to measure the environmental impact of a process or of part of it, considering features such as energy consumption, water consumption, CO 2 emission, recycling, or regulatory compliance. KEIs are defined as a tuple consisting of a metric and a target value representing the goal that has to be achieved.…”

Abstract-Profound understanding of business processes is a key success factor for Business Process Management (BPM). As more and more analytical information like runtime data from process execution or statistical data from business intelligence are available, the problem of business process complexity becomes apparent. Process-relevant information needs to be provided as fast as possible while considering easy and fast interpretation and dynamic changes in stakeholders' demands. The static and usecase specific creation or modification of process visualizations shown in current approaches and tools, however, is complex, time consuming, inflexible and thus costly. To address these shortcomings, we introduce a template-based approach that decouples the creation of visualization templates from concrete process visualizations. The binding of customization points of visualization templates to analytical process information is supported by a graphical editor that enables customization of visualizations in a fast and flexible manner. Moreover, due to the separation of concerns, our approach improves the usability of process visualizations because templates may be created by graphic experts independently from specific visualization demands. The feasibility of our concept is demonstrated by a prototypical implementation.
