TL;DR: This paper presents an introductory overview of BDIM, discusses its main concepts, illustrates gains over conventional IT management approaches and offers a survey of some recent work on the topic in the literature.
Abstract: Business-driven IT management (BDIM) is a new, evolutionary and comprehensive IT management approach that aims to improve IT infrastructure, service quality and business results at the same time. To that end, it needs to model and numerically estimate IT-business linkage. BDIM concepts are finding ways into ITIL-based management processes as well as into new IT infrastructure product offerings such as autonomic computing in order to add increased value to the business. In the hope of contributing to define and characterize this new approach, this paper presents an introductory overview of BDIM, discusses its main concepts, illustrates gains over conventional IT management approaches and offers a survey of some recent work on the topic in the literature.

TL;DR: A method is proposed whereby values for Service Level Objectives of an SLA can be chosen to reduce the sum IT infrastructure cost plus business financial loss, and it is concluded that higher-revenue BPs deserve better infrastructure and the method presented shows exactly how much better the infrastructure should be.
Abstract: A method is proposed whereby values for Service Level Objectives (SLOs) of an SLA can be chosen to reduce the sum IT infrastructure cost plus business financial loss. Business considerations are brought into the model by including the business losses sustained when IT components fail or performance is degraded. To this end, an impact model is fully developed in the paper. A numerical example consisting of an e-commerce business process using an IT service dependent on three infrastructure tiers (web tier, application tier, database tier) is used to show that the resulting choice of SLOs can be vastly superior to ad hoc design. A further conclusion is that infrastructure design and the resulting SLOs can be quite dependent on the “importance” of the business processes (BPs) being serviced: higher-revenue BPs deserve better infrastructure and the method presented shows exactly how much better the infrastructure should be.

TL;DR: This paper model the impact of SLA violations when the implementation of changes is done after their deadline and shows that optimizing the scheduling of changes can result in significant savings to an IT support organization.
Abstract: Change management is one of the most critical processes in IT management. Some of the reasons are the sheer number of changes and the difficulty of evaluating the impact of changes on the IT services being provided. Through carrying out a survey with IT managers and practitioners, we have found that, among the activities performed during change management, change scheduling (allocating changes to change windows) is the most problematic one. In this paper we solve the change scheduling problem by using a business-driven approach that evaluates the impact of a change schedule in terms of the financial loss imposed on the service provider. Toward this aim, we model the impact of SLA violations when the implementation of changes is done after their deadline. A change scheduling optimization problem is then formalized and its solution is applied to a typical scenario. The results show that optimizing the scheduling of changes can result in significant savings to an IT support organization.

TL;DR: This article introduces BDIM, discusses how it can be enacted, and illustrates its benefits and gains over conventional IT management.
Abstract: Unlike the conventional way of managing IT that uses technical objectives and metrics only, such as availability, response time, and throughput, business-driven IT management (BDIM) drives IT management decisions from a business perspective by adding business measures, such as profit, cost, and customer experience. Research on BDIM is gathering interest in both academia and industry worldwide. This article introduces BDIM, discusses how it can be enacted, and illustrates its benefits and gains over conventional IT management.

TL;DR: This paper presents a research agenda for BDIM, reviewing BDIM concepts and proposing a framework to assist in defining and describing BDIM usage domains, and discusses ongoing work and some research challenges.
Abstract: Business-driven IT management (BDIM) aims at managing enterprise IT infrastructure and services efficiently and at improving business results at the same time. BDIM is based on mappings between IT technical performance metrics and business relevant metrics and exploit the linkage to provide decision support to IT management so as to maximize business value and IT-Business alignment. As an example, the number of successfully executed IT infrastructure changes can be mapped to financial loss due to the service disruption experienced by customers when the changes take place. Up to now, there has been some research effort in proposing and applying BDIM solutions to IT management with potential gains for the business. However, much remains to be researched, prototyped and validated before this new IT management discipline can become widely applicable. This paper presents a research agenda for BDIM. After reviewing BDIM concepts and proposing a framework to assist in defining and describing BDIM usage domains, the paper discusses ongoing work and outlines some research challenges.

TL;DR: Deming's theory of management based on the 14 Points for Management is described in Out of the Crisis, originally published in 1982 as mentioned in this paper, where he explains the principles of management transformation and how to apply them.
Abstract: According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

TL;DR: In this article, Nonaka and Takeuchi argue that Japanese firms are successful precisely because they are innovative, because they create new knowledge and use it to produce successful products and technologies, and they reveal how Japanese companies translate tacit to explicit knowledge.
Abstract: How has Japan become a major economic power, a world leader in the automotive and electronics industries? What is the secret of their success? The consensus has been that, though the Japanese are not particularly innovative, they are exceptionally skilful at imitation, at improving products that already exist. But now two leading Japanese business experts, Ikujiro Nonaka and Hiro Takeuchi, turn this conventional wisdom on its head: Japanese firms are successful, they contend, precisely because they are innovative, because they create new knowledge and use it to produce successful products and technologies. Examining case studies drawn from such firms as Honda, Canon, Matsushita, NEC, 3M, GE, and the U.S. Marines, this book reveals how Japanese companies translate tacit to explicit knowledge and use it to produce new processes, products, and services.

TL;DR: In this paper, an extensive review in the sphere of sustainable energy has been performed by utilizing multiple criteria decision making (MCDM) technique and future prospects in this area are discussed.
Abstract: In the current era of sustainable development, energy planning has become complex due to the involvement of multiple benchmarks like technical, social, economic and environmental. This in turn puts major constraints for decision makers to optimize energy alternatives independently and discretely especially in case of rural communities. In addition, topographical limitations concerning renewable energy systems which are mostly distributed in nature, the energy planning becomes more complicated. In such cases, decision analysis plays a vital role for designing such systems by considering various criteria and objectives even at disintegrated levels of electrification. Multiple criteria decision making (MCDM) is a branch of operational research dealing with finding optimal results in complex scenarios including various indicators, conflicting objectives and criteria. This tool is becoming popular in the field of energy planning due to the flexibility it provides to the decision makers to take decisions while considering all the criteria and objectives simultaneously. This article develops an insight into various MCDM techniques, progress made by considering renewable energy applications over MCDM methods and future prospects in this area. An extensive review in the sphere of sustainable energy has been performed by utilizing MCDM technique.

TL;DR: The Reservoir project is motivated by the vision of implementing an architecture that would enable providers of cloud infrastructure to dynamically partner with each other to create a seemingly infinite pool of IT resources while fully preserving their individual autonomy in making technological and business management decisions.
Abstract: The emerging cloud-computing paradigm is rapidly gaining momentum as an alternative to traditional IT (information technology). However, contemporary cloud-computing offerings are primarily targeted for Web 2.0-style applications. Only recently have they begun to address the requirements of enterprise solutions, such as support for infrastructure service-level agreements. To address the challenges and deficiencies in the current state of the art, we propose a modular, extensible cloud architecture with intrinsic support for business service management and the federation of clouds. The goal is to facilitate an open, service-based online economy in which resources and services are transparently provisioned and managed across clouds on an ondemand basis at competitive costs with high-quality service. The Reservoir project is motivated by the vision of implementing an architecture that would enable providers of cloud infrastructure to dynamically partner with each other to create a seemingly infinite pool of IT resources while fully preserving their individual autonomy in making technological and business management decisions. To this end, Reservoir could leverage and extend the advantages of virtualization and embed autonomous management in the infrastructure. At the same time, the Reservoir approach aims to achieve a very ambitious goal: creating a foundation for next-generation enterprise-grade cloud computing.
