Because airlines face intense competitive pressure, their application development organizations have to be able to change gears quickly. To this end, one US airline's application development group has adopted an iterative development process and established a bi-weekly release schedule. To manage the risk associated with such frequent releases, the airline uses a "release when ready" philosophy, runs each release through five stages of testing, and maximizes the efficiency of each release. By balancing time pressures with quality concerns, this airline's app dev organization is able to release new functionality ahead of its competitors without sacrificing software stability.
