An invisible network of digital technology systems underlies the highly visible networks of roads; waterways; satellites; and power-lines. Increasingly; these systems are becoming the "infrastructures infrastructure;" providing a crucial array of data on network demand; performance; reliability; and security. Digital Infrastructures presents an interdisciplinary analysis of the technological systems that envelop these networks. The book balances analyses of specific civil and environmental infrastructures with broader policy and management issues; including the challenges of using IT to manage these critical systems under crises conditions.

After 20 years of construction scheduling experience I looked around for a wider perspective and picked this book. This is; as the author agrees; two books in one - a scheduling practice book and the laying out of a vision to save the scheduling "profession." He did both "books" admirably except that the second book is incomplete. After designing a whole new way to use and analyze schedules (the awkwardly worded "Momentum science") in a way that got me excited; he reveals that he plans to do two more volumes to finish out this first book. That was a disappointment; but in reading further I was still really satisfied with the amount of useful and wise insights to chew on. Usually; a scheduling book is something that one looks at once or twice or leaves on a reference shelf to collect dust. With this book I was shocked that I read and enjoyed the whole thing.Let me start over. The author is not just writing a book or even the first of three books; he is so frustrated with the state of scheduling (me too!) that he wants to completely reform how it is practiced. Apparently; he is also starting a scheduling college. This book could easily double as a textbook for that college-in-formation. As such it is written in extreme clarity and always back and forth from real project needs to decisions about how to schedule or track schedules.What did I find so valuable? He starts with a clear critique of todays practices to the point where schedules are being ignored. He begins again with the primary goal of scheduling - time management. He highlights the two different construction cultures - control versus collaborative where schedules must be much more people-focused. He gives the outline of the Momentum piece which appears to be (I need the next 2 volumes!) sorta like trending on the cost side. One half-joking example that he puts in here speaks of how a project schedule of 2 years duration that loses 2 days for 3 months in a row would show a negative float of 6 days to therefore predict; from the software alone; that the finish would be 6 days behind schedule. And of course; silly as it is; this points to a trap in thinking that can put total float ahead of some trending metric. Most of the book is about scheduling practices. He manages to make things like activity durations or relationship durations (lags) very interesting. He covers a variety of situations; practices; software settings; etc. always with the clear objective of building a better scheduling practice. In fact he also spends a good bit of energy saying what should not be included or done in schedules always with a reasoning of the pros and cons to the overall objective of better scheduling practices. So; the book is not a simple how-to (in fact he almost never mentions any software since he intends his practices to be good for any software); it assumes that one knows the basics and wants to review them in light of making better schedules and having schedules succeed in the project management world.He comes across as old school and part of the first generation of construction schedulers. But his respect for what scheduling could be seems to have given him the energy to imagine a rather brave new world of scheduling. It is a vision where schedule usefulness would rise over its being ignored or used for arguments. His focus and faith are admirable. The book gave me a big dose of faith and focus around all the little things I see and do as a scheduler - i.e.; I got to go over the little things always with an eye to how they folded into the bigger picture. He most often presented many sides of an argument especially the varying circumstances while giving his always strong conviction of the way to handle something. This determined and optimistic vision is both written as a call to arms to other schedulers as well as a passing of the torch to the next generation. And if his momentum view takes hold; the future will be very different. Impressive.6 of 7 people found the following review helpful. Probably one of the best books on CPM ever writtenBy N. ZonneveldThis is by far the most interesting and comprehensive book Ive ever read on project scheduling. The concept of Momentology is much more viable than Critical Chain and should really deserve more attention.Although not for the novice scheduler; I can wholeheartedly recommend this book to anyone interested in CPM.
