The results indicate that along its development cycle, open source projects exhibit similar reliability growth pattern with that of closed source project. Bug arrivals of most open source project will stabilize at a very low level, even though in comparison, no formal testing activities are involved. This stabilizing point would be viewed as the mature point for adoption consideration. The results also show that general Weibull distribution offers possible way to establish the reliability model; Also, popular measures such as page views and download are not highly correlated with the bug arrival rate and may not be suitable measures for a project's quality.<\/jats:p>","DOI":"10.1145\/1082983.1083273","type":"journal-article","created":{"date-parts":[[2005,11,7]],"date-time":"2005-11-07T19:28:32Z","timestamp":1131391712000},"page":"1-6","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":28,"title":["Open source software reliability model"],"prefix":"10.1145","volume":"30","author":[{"given":"Ying","family":"Zhou","sequence":"first","affiliation":[{"name":"The University of Sydney, Sydney, NSW, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Davis","sequence":"additional","affiliation":[{"name":"The University of Sydney, Sydney, NSW, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2005,5,17]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"ApacheWeek \"Apache 2 release history\" 2004 {WWW document} URL http:\/\/www.apacheweek.com\/features\/ap2  ApacheWeek \"Apache 2 release history\" 2004 {WWW document} URL http:\/\/www.apacheweek.com\/features\/ap2"},{"key":"e_1_2_1_2_1","volume-title":"CIO Research Report","author":"Cosgrove L.","year":"2003","unstructured":"Cosgrove , L.
