abstract = {Services provided by modern organizations are usually designed, deployed, and supported by large-scale IT infrastructures. In order to obtain the best performance out of these services, it is essential that organizations enforce rational practices for the management of the resources that compose their infrastructures. A common point in most guides and libraries of best practices for IT management – such as ITIL or COBIT – is the explicit concern with the risks related to IT activities. Proactively dealing with adverse and favorable events that may arise during everyday operations might prevent, for example: delay on deployment of services, cost overrun in activities, predictable failures of handled resources, and, consequently, waste of money. Although important, risk management in practice usually lacks in automation and standardization in IT environments. Therefore, in this article, we introduce a framework to support the automation of some key steps of risk management. Our goal is to organize risk information related to IT activities providing support for decision making thus turning risk response planning simpler, faster, and more accurate. The proposed framework is targeted to workflow-based IT management systems. The fundamental approach is to learn from problems reported in the history of previously conducted workflows in order to estimate risks for future executions. We evaluated the applicability of the framework in two case studies both in IT related areas, namely: IT change management and IT project management. The results show how the framework is not only useful to speed up the risk assessment process, but also to assist the decision making of project managers and IT operators by organizing risk detailed information in a comprehensive way.},

abstract = {Products and services provided by modern organizations are usually designed, deployed, and supported by large-scale Information Technology (IT) infrastructures. In order to obtain the best performance out of provided products and services, it is essential that these organizations enforce rational practices for the management of resources that compose their infrastructures. For this purpose, in recent years a few standards and libraries of best practices for IT infrastructures and services management have been proposed. Among the most widely accepted proposals, in both academy and industry, is worth mentioning the Information Technology Infrastructure Library (ITIL). A common point in most of those standards and libraries is the explicit concern with the risks related to IT activities. Proactively dealing with adverse and favorable events that may arise during everyday operations might prevent, for example: delay on deployment of services, cost overrun in activities, predictable failures of handled resources, and, consequently waste of money. Although important, risk management in practice usually lacks in automation and standardization in IT environments. Generally, it is performed by stakeholders in interviews and brainstorms, which may be a very time/resource-consuming task and sometimes too imprecise to guide risk related decisions. Therefore, in this dissertation, a framework to support the automation of some key phases of risk management is proposed, aiming to make it simpler, faster, and more accurate. The proposed framework is targeted to work ow-based IT management systems. The main approach is to learn from problems reported in the history of previously conducted work ows in order to estimate risks for future executions. Furthermore, comprehensive and interactive risk reports are proposed aiming to ease the analysis of assessed risks by involved humans. The proposed framework had its applicability evaluated in two case studies both in IT related areas, namely: IT Change Management and IT Project Management. The results show how the framework is not only useful to speed up the risk assessment process, but also to assist the decision making of project managers and IT operators by organizing risk detailed information in a comprehensive way. In addition, the modular approach employed in the design of the proposed framework allows it to be generic enough to t in di erent contexts (changes and projects) and still customizable to adapt to more speci c requirements.},

In some cases, these changes might raise failures, causing disruption to provided services and consequently affecting the business continuity. Therefore, it is strongly recommended to evaluate the risks associated with changes before their actual execution. Learning from information of past deployed changes it is possible to estimate the risks for recently planned ones. Thereby, in this paper, we propose a solution to weigh the information available from past executed plans by the similarity calculated in relation with the analyzed change plan. A prototype system has been developed in order to evaluate the effectiveness of the solution over an emulated IT infrastructure. The results obtained show that the solution is capable of capturing similarity among activities in change plans, improving the accuracy of risk assessment for IT change planning.},

abstract = {Information Technology (IT) products and services provided by modern organizations are designed in projects that often involve large amount of resources (e.g., humans, hardware, and software). It is essential that organizations enforce rational practices for project management, in order to successfully conclude projects and avoid waste of substantial resources.

Although important, risk assessment in IT projects is usually performed by stakeholders in interviews and brainstorms which may be a very time/resource-consuming task.

Since changes are imminent in such a dynamic environment, failures during this process may directly affect business continuity. Hence, risk assessment is a key process in IT change management. Despite its importance, risks are usually assessed by humans based on empirical knowledge, leading to inaccurate basis for decision making. In this paper, we present a solution for automating the risk assessment process, which combines historical data from previous changes and analyzes impact of changes over affected elements.

abstract = {The growing necessity of organizations in using technologies to support to their operations implies that managing IT resources became a mission-critical issue for the health of the primary companies' businesses. Thus, in order to minimize problems in the IT infrastructure, possibly affecting the daily business operations, risks intrinsic to the change process have to be analyzed and assessed. Risk management is a widely discussed subject in several areas, although for IT change management it is quite a new discipline. The information technology infrastructure library (ITIL) introduces a set of best practices to conduct the management of IT infrastructures. According to ITIL, risks should be investigated, measured, and mitigated before any change is approved. Even with these guidelines, there is no default automatic method for risk assessment in IT change management. In this paper we introduce a risk analysis method based on the execution history of past changes. In addition, we propose a failure representation model to capture the feedback of the execution of changes over IT infrastructures.},

abstract = {Modern organizations take advantage of complex IT infrastructures in order to support their daily operations. Since these environments require special care, whenever changes become necessary, risks associated to them should be investigated.
