    - The defect amplification model [IBM81] is used to illustrate the generation and detection of errors during the preliminary design, detail design, and coding steps of the software engineering process.

    - A software development step is represented by a box.

    - Errors may be inadvertently generated during the step.

    - Review may fail to uncover newly generated errors and errors from previous steps, resulting in some number of errors that are passed through.

    - In some cases, errors passed through from previous steps are amplified (amplification factor, x) by current work.
