Open architecture is a system in which the specifications are made public to encourage third-party vendors to develop add-on products. In defense acquisition, the term extends to creating separate modules in a larger system, each of which can be updated to modernize the entire system without rebuilding it, and the modules can be produced by different vendors, promoting diversity and competition at the module or component level.
