Query: Book Review: Rapid Problem Solving with Post-It Notes by David Straker

Rapid Problem Solving with Post-It Notes by David Straker is one of the those books that had been on my wishlist for quite a while.The book is quite handy, very concise and so easy to understand.The author presents six simple ways to approach problem solving using Post-it Note. What I like about the book most is that it is very clear on what the tools are, how they are used and when to use them. The examples used are also very clear and appropriate.As someone who leads innovation teams, product improvement teams, product development and cost engineering teams, these tools are very helpful.Highly recommended for those who work in teams.
