Case Two British Telecom Spreading Agile Development across the Globe In 2005, British Telecom (BT) took a big risk: the company dropped its use of the waterfall system development process and embraced agile development. Previously, BT had outsourced the gathering of system requirements to a third company, which would typically take three to nine months to meet with customers and stakeholders and create a requirements list. Next, the project would move back to BT where programmers often struggled to interpret the requirements and then develop and test the system within 18 months-although some projects needed more time. In late 2005, however, BT took only 90 days to roll out a new Web-based system for monitoring phone traffic. The new system allowed traffic managers to change switches and other physical devices more quickly in order to handle shifts in load along BT's telecommunications network. The success of this initial project reverberated throughout the IT world, as BT became the first telecommunications giant to adopt agile developmentsometimes developing products in three 30-day iterative cycles, The new system development approach had other advantages, too: programmers and customers communicated closely and teams from different locations around the world, initially the United Kingdom and India, worked together to develop the system.
