Obama's troubled healtcare.gov is trying to serve 80% of its applicants with a health insurance plan. That needs to be good enough until the end of the month. More seems not possible amidst all the problems.
The Obama administration lowered its goal of success for HealthCare.gov internally. If 80% of users can get a health insurance through the site, they break out the champaign according to a source of The Washington Post. If 80% sounds familiar, you are right. The Obama administration uses the Pareto principle (Wikipedia) aka 80-20 rule. It is an interesting rule and I have used it many times in my software product management past. Basically reaching 80% of the goal is good enough. The last 20% do not bring by far as much as the first 80%.
Using this rule to a service like HealthCare.gov is though not ideal. Just imagine if 20% of Facebook's users cannot use Facebook. We would call that a Facebook service outage. If Facebook would have that issue for a month, the stock price would plummet.
Watch the Healthcare.gov commercial below. It does not say that only 80% of users can get a health insurance.
