Word of the Day: rolling forecast

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

“It’s no secret that the BYOA trend creates new security challenges. Internal applications typically rely on firewalls, but best practices for cloud-based services usually rely on secure passwords and encryption technologies.”Chris Moyer

Because a rolling forecast window requires routine revisions, it is sometimes referred to as a continuous forecast or an iterative forecast. Continued…
