On October 1st, 2013, the first Open Enrollment Period (OE1) under the Affordable Care Act kicked off to much hoopla. As everyone knows, the largest of the ACA exchange websites, HealthCare.Gov, infamously melted down at launch due to a multitude of hardware and software problems ranging from insufficient server capacity to poor workflow design to buggy coding and much, much more. However, as Steven Brill detailed in the March 10, 2014 issue of Time magazine, by early December, the worst of the problems had been resolved, and by the time the second Open Enrollment Period came along a year later, HealthCare.Gov had been completely overhauled, with additional improvements and enhancements every year since.
The difference has been dramatic: On October 1, 2013, only six people (not six thousand or six hundred...six) were able to actually make it all the way through the HC.gov interface and enroll in a healthcare policy. On December 15, 2016, six hundred and seventy thousand enrolled.
