"Methodologies are like cookbooks: follow their recipes and a successful system will result. Some methodologies are modest in scope and depth, while others contain literally thousands of pieces of work, or tasks, tied together into templates. Each template is appropriate for a specific type of development project" (from Agile Software Development with Scrum)

As the quote suggests processes are like recipes (XP, Scrum, RUP, V-Model, Water****,...) but if you want to apply them successfully you need to know more. You need to know when and how to tweak the recipes. You need to know which ingredients are the most important ones and how they work together. You need to know which tools are crucial, how they work and when to use them.

It's about time that more people start to look behind the recipes...
