What was wrong with the design of HealthCare.gov

The healthcare dot gov website had many problems. Some of the problems included: “page not found” and “system down” error messages, spinning icons, and faulty information from the exchanges [1]. Their Data Center had periods of outage which also affect other agencies [2]. All of this combined with downtime expected until late November [3], makes it seem like they needed to implement a better design from the start. The project was initially very complex, including proper use of software and hardware (datacenter), and being an entire system built from the ground up. It is the mashup of three major contracts, each with their own requirements: to provide a new e-commerce site, a new information middleware infrastructure, and a hosted data center integration project[4], this just adds to the complexity. Second, the whole system depended on data provided by Experian, which was error-prone[1], they needed to have time to make sure their code can handle all the errors that can come up. Third, the specifications for the project were delayed repeatedly then changed frequently up to within a month of the target release date[4]. This resulted in design changes and rewriting parts of the system without having time to check for bugs. For which they didn't even know how to across multiple systems [4]. Since the requirements kept changing until the last minute, there was no way to do a full site testing until just weeks before the release date. Nearly every component of the site was brand new, untested and unproven against any real-world load. Because of the general dislike of obamacare coming from certain groups and instead of having to do a rolling release of bug-fixes and upgrades, they should have released the project late but working.
