Practical Risk Assessment for Project Management ReviewThe ideal audience for this book is relatively narrow, consisting of readers who meet the following two criteria: (1) new to risk management techniques, and (2) using Palisade @Risk. In fact, this book comes close to being a tutorial on using @Risk, which is a popular commercial product that works within Microsoft Excel and project management programs.
If you are new to advanced techniques in project risk management you'll like the way the author succinctly covers all of the key elements of project risk assessment, project finance forecasting, and simulation and modeling. Considering the complexity of the subject area, and the fact that both probability and simulation techniques are covered, the author does a remarkable job of conveying the wide range of topics in a scant 134 pages. I especially liked the generous use of graphs and examples, and the way each topic was broken down into easy-to-grasp facts and steps.
However, even without @Risk you can learn much about risk assessment from this book, including a refresher on probability distributions, how to perform an assessment using manual techniques, and modeling and simulation with an emphasis on Monte Carlo simulation.
The only problem I have with this book is that it's out of date with respect to @Risk, which has evolved into a much more capable tool since this book was first published 7 years ago. Since one of the this book's strengths is the way it teaches how to apply @Risk to real world project risk assessment, the fact that it's out of date with respect to the software version diminishes its value.Practical Risk Assessment for Project Management OverviewIn the estimating, planning and management of any project, large or small, an understanding of the impact of risk is critical. This book explains how the growing number of people choosing to or forced to organise their work as projects can make realistic assessments of the uncertainty affecting costs, timescale and revenue, before commitments are made. A clear analysis of the role of uncertainty is combined in this concise and practical handbook with simple, cost-effective techniques for measuring and modelling the overall risk to a project's budget and schedule. There is advice and help here for the whole project team, including project managers; bid managers; project sales professionals; planners; estimators; managers running a project-based business; and consultants and auditors advising a projects business. Drawn from the author's extensive experience on projects ranging in scale from a few man-months to hundreds of man-years, the book will beelevant to anyone involved in a project-based business. Examples are presented as simple models, built in spreadsheets using the @Risk software package. No more than basic knowledge of Lotus 1-2-3?? or Excel?? will be required by the reader.

Transaction Processing: Concepts and Techniques (The Morgan Kaufmann Series in Data Management Systems) ReviewFor nearly a decade this book has been the definitive reference on transaction processing. Although the more recent, May 2001 book titled "Transactional Information Systems: Theory, Algorithms, and the Practice of Concurrency Control" by Gerhard Weikum and Gottfried Vossen will probably supplant this book as the standard reference, there is still much material that makes this book useful.
In particular, this book covers the following topics in more depth than the newer boom cited above:
- Fault tolerance and availability, both topics are covered in depth from hardware and software perspectives. This is unique for a book on transaction processing in that most books on the subject confine their scope to software and databases.
- A wide and complete survey of transaction models. True, some of this material is about models that are falling into disuse, but the value is the way the authors go deeply into the mechanics. I've always felt that this part of the book is the most valuable because the principles can be refactored into hybrid models. Moreover, comparing this material with the newer book by Weikum and Vossen shows that these principles are still employed in today's TP solutions.
Material about transaction processing monitors is obviously out of date, but, like the TP models, the principles still apply to contemporary systems. My recommendation is if you are going to buy a single book on the topic get the Weikum and Vossen I cited in the first paragraph. However, if your budget allows, I also highly recommend this book as well because of the depth in which fault tolerance and TP models are covered. If you want to just learn the basics of TP I recommend that you consider "Principles of Transaction Processing" by Philip A. Bernstein and Eric Newcomer because it is less daunting than this or the Weikum and Vossen book (both of which are 1100+ pages).Transaction Processing: Concepts and Techniques (The Morgan Kaufmann Series in Data Management Systems) Overview
The key to client/server computing. Transaction processing techniques are deeply ingrained in the fields ofdatabases and operating systems and are used to monitor, control and updateinformation in modern computer systems. This book will show you how large,distributed, heterogeneous computer systems can be made to work reliably.Using transactions as a unifying conceptual framework, the authors show howto build high-performance distributed systems and high-availabilityapplications with finite budgets and risk.

The authors provide detailed explanations of why various problems occur aswell as practical, usable techniques for their solution. Throughout the book,examples and techniques are drawn from the most successful commercial andresearch systems. Extensive use of compilable C code fragments demonstratesthe many transaction processing algorithms presented in the book. The bookwill be valuable to anyone interested in implementing distributed systemsor client/server architectures.
