The analysis of time series data is an important aspect of data analysis across a wide range of disciplines, including statistics, mathematics, business, engineering, and the natural and social sciences. This package provides both an introduction to time series analysis and an easy-to-use version of a well-known time series computing package called Interactive Time Series Modelling. The programs in the package are intended as a supplement to the text Time Series: Theory and Methods, 2nd edition, also by Peter J. Brockwell and Richard A. Davis. Many researchers and professionals will appreciate this straightforward approach enabling them to run desk-top analyses of their time series data. Amongst the many facilities available are tools for: ARIMA modelling, smoothing, spectral estimation, multivariate autoregressive modelling, transfer-function modelling, forecasting, and long-memory modelling. This version is designed to run under Microsoft Windows 3.1 or later. It comes with two diskettes: one suitable for less powerful machines (IBM PC 286 or later with 540K available RAM and 1.1 MB of hard disk space) and one for more powerful machines (IBM PC 386 or later with 8MB of RAM and 2.6 MB of hard disk space available).
Up until now, no one has attempted to lay out the entire blueprint for architecting a complete IT service management supporting infrastructure--until this book. What are the supporting toolsets and technologies that need to support an IT service management infrastructure? What databases need to be put into place? What are all the IT service management roles and responsibilities to effectively operate this infrastructure? What kinds of IT support services does almost any IT organization deliver? Get it all here. This book lists the CI types, toolset descriptions, detailed roles and activities, and much more. Get a firm handle on the data, functions, services, processes, organization, and technologies all needed to effectively build and operate a complete IT service management infrastructure. Explore approaches for reviewing and assessing your current toolsets, data, processes, and services. See where gaps might exist. Find areas that might be missing tools or have too many tools doing similar functions. Validate IT service management roles and activities. "One can put together an entire IT service management operation just from the descriptions in this book!" "If I had to build a large IT infrastructure or data center from scratch, this book becomes my most critical reference!"
Designed for the analysis of linear time series and the practical modelling and prediction of data collected sequentially in time. It provides the reader with a practical understanding of the six programs contained in the ITSM software (PEST, SPEC, SMOOTH, TRANS, ARVEC, and ARAR). This IBM compatible software is included in the back of the book on two 5 1/4'' diskettes and on one 3 1/2 '' diskette. - Easy to use menu system - Accessible to those with little or no previous compu- tational experience - Valuable to students in statistics, mathematics, busi- ness, engineering, and the natural and social sciences. This package is intended as a supplement to the text by the same authors, "Time Series: Theory and Methods." It can also be used in conjunction with most undergraduate and graduate texts on time series analysis.
If you read through this book and still dont believe there is a critical need for IT Service Management then good luck seeing if you can survive in IT for the next 5 years. Agile, DevOps, Lean IT, Virtualization, Application Lifecycle Management, Cloud Computing and many other technologies are rapidly pulling IT in many directions. These modern ways of operating IT to cope with a world of rapid change will not go away. Somehow they need to be pulled together to avoid the chaos. Service Management is the glue needed to hold these all together. There is no IT value for the business until the point a service is received. For this reason, this book is written for IT leaders, managers and practitioners from a Service Management perspective. Having the best development practices, be it Agile, DevOps or others means little if a service is not delivered to the business. When they need it. High Velocity ITSM is about transitioning the IT Organization from traditional waterfall slower service development and support to a service delivery organization operating at high velocity. This book provides practical guidance for: ? Transitioning IT towards high velocity ITSM ? Using Agile and DevOps for rapid service build ? Using Lean IT to operate at high velocity ? Streamlining your ITSM management processes ? Building a Lean IT CSI Program ? Learning and applying modern IT methods and much more!
Managing the IT Service Process is the first book of its kind to recognize the truth of IT Service delivery. It takes the overall view of the service management process and links together the elements of service level management, systems availability, costs and benchmarking, and the helpdesk. In the last 5 years there has been a major structural shift in the IT industry with the traditional position of Helpdesk Manager being replaced by a new function of IT Services Manager. The industry is now concentrating on the formulation of an end-to-end service process that replaces the previous norm of several disparate and non-integrated sections in an IT department such as the helpdesk, applications maintenance, operations, development procurement and systems management. Managers are focusing on a totality of management so they can correlate costs and processes and offer their customers an integrated service. Managing the IT Services Process is an instructional manual written by an acknowledged industry expert and includes techniques, charts, methods, case studies and anecdotes to support the text. The author encourages the reader to formulate an end-to-end IT service process by using a step by step approach. The text describes and encourages integration in IT and therefore will be useful for managers involved in the unified process.
What services does the IT organization really deliver? Rather than discuss the theory around what a service catalog or service portfolio is, this book gives you the actual IT service descriptions for running, operating, and managing an entire IT infrastructure. It's all here--complete service descriptions, catalog and portfolio templates, service implementation plans, service governance processes, and much more all packed into this one handbook! Just about every IT support service is described in this book. Take the service descriptions you need, mix, match and customize them to quickly create the content needed for your own service catalogs and portfolios. "Many books talk about how to build a service catalog--this book is a service catalog!" "We really struggled to identify and pull our IT services together until we saw this material--it saved us months!" "With this material, we can finally tell the business what IT actually delivers to them!" "A valuable reference resource for ITSM practitioners, service managers, CIOs, procurement managers, and anyone else sourcing the services needed to run an entire IT infrastructure operation!" "One can put together an entire IT service management operation just from the service descriptions in this book!"
IT Service Management (ITSM) is a process-oriented management philosophy focused on providing quality IT services and aligning IT with the goals of the business. ITSM has become increasingly popular in the United States over the past few years, and is expected to become highly prevalent in most businesses in the near future. Although ITSM is process-oriented, companies often employ software tools in order to support or automate portions of these processes. Selecting the right software tool for a certain business and IT environment is crucial, as selecting the wrong tool can carry a heavy cost, both financially and in service quality. This thesis proposes a framework specifically designed to evaluate ITSM software products. By combining relevant aspects of current evaluation methods with an ITSM context, the focused framework will better meet the needs of companies and organizations interested in evaluating IT Service Management software products.
