As any other systems, e-government needs to be nurtured and grown up. To help understand the developmental phases of e-government, several 'stages of growth' models are reviewed and compared in this chapter. These stages outline the multi-perspective transformation necessary within government structures and functions as they make transitions to fully functional e-government. Similarities and differences of these models are discussed. Following this discussion, the Layne and Lee model is discussed in detail, with technological and organizational challenges.
