The i* Guide is intended to be both an introduction to i* for new users and a reference guide for experienced users. It is constituted of basic i* notation and a glossary and provides relatively elaborated material on the usage of the i* framework and notation through introducing guidelines that are associated with discussions and illustrations. These Guidelines, which touch on some of the fundamental concepts of i* Framework, are intended to, among other desirable modeling characteristics, improve the readability, understandability, usability, and feasibility of i* models and enhance the overall consistency and effectiveness of the i* modeling process. Therefore, the net positive effect is to reduce variation in practice among users of i* modeling framework. Furthermore, the i* Guide refers the readers to original sources where more advanced, detailed, or thorough material and discussions can be found.
As this guide is intended to be part of the i* collaborative wiki we encourage feedback and collaboration in terms of suggesting alternative i* syntax and semantics, including extensions to the Framework. However, in order to keep the Guide brief and easily understandable, we suggest collecting i* adaptations, expansions, and further examples in separate document(s), namely the istarSyntaxVariations page. If enough variations of i* usage are collected, this can facilitate interesting and useful comparisons.
Moreover, and to facilitate this collaboration process, i* wiki will host two versions of the i* Guide: A stable version and an open version. The open version is accessible to all registered i* wiki users to comment and provide suggestions on individual guidelines. Therefore, it is highly appreciated and valued that i* community utilizes this open version as a basis to develop and enhance the i* Guide further. In effect, you can think of the open version as a prototype that invokes and generates further input toward the achievement of a better artifact.
