As with the benefits of open approaches to the cloud discussed above, open application development can leverage open source software networks to accelerate the pace of innovation by bringing IT professionals together to work across an enterprise and access commercial best practice. If an agency’s IT workforce is saddled by static infrastructures and closed systems, then the introduction of new technologies will be constrained by the capacity of those systems for change. In contrast, an open approach to application development expands the playing field of ideas, prototypes, and pilots for new innovation considerably. In addition, from a workforce perspective, openness helps increase the job pool of qualified professionals as opposed to siloed applications that only a few know how to use and maintain. This is growing in importance as government employees reach retirement age at an ever-increasing rate and the public sector competes for talent with the private sector.
