Reuse of existing software components from previous projects without complete analysis. Functionality omitted due to budget or time constraints. "improvement" to software that are not in requirements: logical design errors. Errors in interpreting the design document, errors related to incorrect use of programming language constructs, etc: coding errors. Errors in interpreting the design document, errors related to incorrect use of programming language constructs, etc: non-compliance with documentation and coding instructions.
