Governments at all levels and across all branches have been urged to become leaner and smarter, providing better and faster service at lower cost. Such fundamental change, however, inevitably impacts the business processes governments work by. So far, though, business process change has mostly been studied in the private sector. Electronic government (e-government, e-gov) appears as a potent enabler when reinventing the way government is doing business. According to Layne and Lee (2001), four stages of development can be distinguished in electronic government. This chapter maps the dimensions of business process change into the developmental stages of electronic government, providing a roadmap for business process change through electronic government.
