Before Electric Cloud:

Long, unreliable software builds drained development resources. Mercury’s build inefficiencies created a bottleneck in the development cycle that adversely affected the entire team. Not only did it require a Mercury release engineer’s time to correct, it also involved developers and QA engineers who had to wait for the next successful build. Mercury’s popular MCOE™ (multicomputer operating environment) is one of the company’s core offerings. With over one million lines of code, the MCOE platform is a complex application, which in turn has made its development process complex as well. Compounding the development demands, the software must be built across 12 different operating systems.
