Source: http://www.agilemodeling.com/essays/amdd.htmFirst, let’s start with how to read the diagram. Each box represents a development activity. The envisioning includes two main sub-activities, initial requirements envisioning and initial architecture envisioning. These are done during iteration 0, iteration being another term for cycle or sprint. “Iteration 0” is a common term for the periodbefore you start into development iterations, which are iterations one and beyond (for that release). The other activities – iteration modeling, model storming, reviews, and implementation – potentially occur during any iteration, including Inception. The time indicated in each box represents the length of an average session: perhaps you’ll model for a few minutes then code for several hours.
