• ##### What does that mean exactly?(12+ / 0-)

What is the "error rate" measuring? Does it mean that every time you click on something on the page, your chance of encountering an error is 1%? Or does it mean that you have 1% chance of an error in your entire session? If the former, 1% doesn't seem that great, as if you have to go through, say 50 operations to complete a session, your chance of failing before you get through it all is still roughly 50%.

• ##### The error rate was 6 percent last Friday(7+ / 0-)

How does the math work out for that? If the result is an impossible sum that does not match with the fact that 900,000 applications were completed in October -- then you will know what the 1 percent is based on.

• ##### Realtive change...(3+ / 0-)

The relative change is probably a better indication of the scale of improvement than necessarily the absolute number.

Unfortunately, they are probably finished with the easy stuff and now have to deal with the hard stuff and diminishing returns as each fix does not bring the error rate down as much as the last.

• ##### not sure about that 50%(3+ / 0-)

I doubt it is 50 operations.  Maybe 25.  Let's say the probability of success on any operation is .99, and to make it simple, assume the actions are independent (that might not be realistic.)   I'll let X be a binomial random variable that counts the number of successes.

According to Wolfram Alpha, the probability of ALL successes is about 78%.   Still not that great.

If the probability of success on any operation is .995, the probability of ALL successes is 88%.   So let's hope they are getting that error rate down.

• ##### Not that complicated...(2+ / 0-)

I think y'all are reading too much complexity into the term "error rate." They most likely mean the proportion of applications transmitted to insurers that are incorrectly formed. You'll recall it was a very high proportion early on, for the few applications that did get through.

• ##### I hope you're right(0+ / 0-)

I like your interpretation better than error rate per operation :-)

• ##### well there are a number of ways to frame it(0+ / 0-)

It could also be the rate of 5xx return codes from the servers. Trying to discern what is actually meant by error rate isn't really a useful exercise.

Im guessing that by the end of the month, it'll be improved enough that it's not a big story,  but there'll still be significant issues to work through. Im guessing that it'll be a truly usable product more towards end of December. Judging from the comments, there are still some pretty major issues.
