This book made me understand more about my current job. In particular, how Thomas Siebel broke away from Larry Ellison to form the Siebel CRM Systems, Inc. that pioneered CRM applications. If Siebel (now Oracle CRM On Demand) did not gain traction in the 90's, there would not have been Salesforce, Clarify, and other CRM apps. Or maybe their release might have been delayed by a few years.
I also liked how this book puts CRM (for enterprise users) in the scheme of things: how it is related to intended users: PRM (for channel users) and eCRM (for online customers) and these three to business functions such as sales, marketing, e-commerce and service. I knew some of these but it was nice to see everything depicted in a chart. In fact, I rebuilt the chart and will incorporate this to a presentation deck that could be helpful for new CRM or Client Experience analysts.
I only have a bit of regret because I postponed reading this 2001 book by few years. Or to be precise, I only saw this book maybe a decade after its release to the market. I mean, this could have helped my understanding of my job when I started in 2012. The disadvantages of technical books especially in Information Technology is that technology changes so fast that after the manuscript is approved and much more when the book is published, there could already been changes on what the book is about. For example, in 2005 (just 4 mere years after this book is published) Siebel was bought by Oracle. Then in 2015 (10 years after Oracle bought Siebel), Oracle Sales Cloud is introduced to the market. Obviously, after adopting the Siebel functionalities, Oracle will be dumping it and push its clients to migrate to Sales Cloud.
So, the lesson for me here is to read IT books right away and don't treat them like classic literature.
