It's 30% failure in 3 months. How high can that go in 6 months, in 12 months, or in the expected life span of a Dell monitor?

- HeyLaughingBoy 14y agoManufactured products tend to have two spikes in their failure rate: soon after being put into service (manufacturing defects showing up when the product has been used a bit) and near end of life (parts are wearing out due to long usage). In the middle, the failure rate is pretty flat. Monitors failing within 3 months suggests that you're seeing the infant mortality part of the curve. If a particular monitor lasts 3 months, it will likely last for many years.

- cjdavis 14y agoIt's more of two slopes rather than two spikes: https://en.wikipedia.org/wiki/Bathtub_curve https://en.wikipedia.org/wiki/Bathtub_curve
- dvdhsu 14y agoTangentially related, but still interesting: most people think hard drives have a bathtub curve when failure rate is plotted against time. Turns out this isn't true. Schroeder and Gibson: "Contrary to common and proposed models, hard drive failure rates don’t enter steady state after the first year of operation. Instead failure rates seem to steadily increase over time." http://www.pdl.cmu.edu/PDL-FTP/Failure/CMU-PDL-06-111.pdf http://www.pdl.cmu.edu/PDL-FTP/Failure/CMU-PDL-06-111.pdf
