where are the most errors introduced in software projects
Software bug Most bugs arise from mistakes and errors made in either a program's source code or its design, or in components and operating systems used by such programs. A few are caused by compilers producing incorrect code. A program that contains a large number of bugs, and/or bugs that seriously interfere with its functionality, is said to be buggy (defective). Bugs can trigger errors that may have ripple effects. Bugs may have subtle effects or cause the program to crash or freeze the computer. Other bugs qualify as security bugs and might, for example, enable a malicious user to bypass access controls in order to obtain unauthorized privileges.
Errors and omissions excepted Errors and omissions excepted (E&OE[1]) is a phrase used in an attempt to reduce legal liability for potentially incorrect or incomplete information supplied in a contractually related document such as a quotation or specification.
