Book Review – “The Tipping Point”


The Tipping Point: How Little Things Can Make a Big Difference is a book that is about the way ideas, things and behaviors go from obscurity to ubiquity in a very short period. The basic model is that of an epidemic in which three types of factors contribute to quick dissemination: 1) the network of people involved including “connectors”, “mavens” or respected experts, and “salesmen”, 2) the ability of that which is spreading to stick around, the “stickiness factor”, and 3) the importance of small physical, mental and social factors, in creating a conducive environment. The Author, Malcolm Gladwell, includes some excerpts on his web site.

This is a fascinating book, well written. Some of the anecdotes and “case studies” are mind-blowing. However, there is a bit of weakness in parts. In particular, the Afterword and the sections on The Power of Context are weakly put together – ideas do not flow well, or are too stream-of-consciousness. As well, the weight of evidence, while strong, is not totally convincing. That said, there are a couple of really fabulous stories.

One story that stands out is the study related to the “Good Samaritan”. In brief, researchers set up an experiment to test what factors influenced a person’s behavior when presented with someone obviously in need of help. At a seminary, the researchers had students prepare and deliver a brief talk on some topic. One of the topics given randomly to some of the students was the story of the Good Samaritan. The students were to take a short amount of time to prepare their talk and then immediately go to another building to deliver it. Planted by the researchers along the path to the second building was an actor made up to appear in a great deal of physical distress. As each student was sent out the door, the researchers would breifly comment either that the student was running a little early, or that they were late and needed to hurry to deliver their talk. The results were astounding: of those students who were told that they were late 90% ignored the person in distress regardless of the topic of their presentation, while 63% those with a few minutes to spare stopped to help (pages 163-165).


There are several ways in which this book is relevent to those of us practicing Agile Work and related methods. Most obviously, the ideas in The Tipping Point suggest some lines of action we can take to promote Agile: finding the connectors, mavens and salespeople, working to make Agile sticky, and making the environment hospitible to the spread of Agile. This applies both inside organizations and in the world at large.

In my own opinion, the drafters of the Agile Software Manifesto, either by design or otherwise, came up with an incredibly sticky term: Agile.

Finally, when coaching a team to adopt agile practices, it may be most important to focus on the Power of Context. Small suggestions, small physical changes, body language, all can have a large influence on the success or failure of an agile adoption. If a coach (Scrummaster/Team Lead/etc.) can find the connectors, mavens and salespeople in the sphere of influence of the team, and convince those people of the efficacy of Agile, then convincing the team will become that much easier.
