Enterprise and business architects spend a lot of time documenting business capabilities. This book provides a description of many required tools such as process diagrams, use cases, activity diagrams, etc.
If you are reading my blog you are probably one of my friends who know all about these things already. Nonetheless, this is a great book to brush up on the details or provide as a reference to a mentee.
I usually refer to this book online via Books27x7 online or on my iPad using Safari. God bless IBM for subscribing me to these services!
