Strengths Finder 2.0 (2007) was written by leading business author Tom Rath, a consultant at Gallup. Used in conjunction with an online self-assessment tool, Strengths Finder 2.0 provides a report highlighting individual talents and how to work best with them.
I followed this path and was impressed with the report I received on my strengths. I feel it was really accurate and reflects who I am and how I work. According to Strengths Finder 2.0, I am Strategic, Learner, Intellection, Context and Arranger. Yup, that's definitely me; a reassurance of my abilities to self-assess. Referring back to the book, the ideas for action provide little fortune cookies of wisdom that will help me to build on my strengths. Reading about other strengths also provides insight into other people who have different strengths to my own.
With regard to the assessment, it is a shame that you cannot go back and take the test again - to see if you change over time and to test the validity of the initial assessment. It was also a bit disappointing that you only get to know your top five strengths. I would have found it more useful if the report provided me with a list of all my strengths in order, so I could know what my other strengths are (and are not) - even though this is contrary to the author's point of focusing on your core strengths.
The whole process - to read the introductory section and take the assessment - only took an about an hour, but the report provided to me I will be pondering for some time to come. This is not a book for everyone, but for those who are introspective and want to better understand what they are good at, Strengths Finder 2.0 is a worthwhile investment.
