This toolkit  is build upon a number of product innovation methods that are essential to understand and implement the relevant knowledge. These methods have been translated into practical tools that significantly reduce the complexity of SPIN, allowing you to practice with SPIN in a gradual manner. The toolkit is structured with a layered approach to information  –  a broad overview, detailed step-by-step methodologies relevant to various (product) contexts (with local example projects), and worksheets to help support the tools.
