    Abstract

    According to many sources, most of the defects of excellent software are produced in the requirements specification phase of the software design process. In average software, the share is also remarkable. There are many kinds of sources for safety requirements specification, and they address different aspects of safety. The origin of safety requirements is risk assessment, but other sources are also needed. The machine standards describe most of the risks related to the specific machine, and furthermore present them as complete requirements. Functional safety standards give information on safety principles, design process safety integrity, safety functions and methods. This paper compares different sources of requirements by using an example, which is related to the boom control of a mobile elevating work platform. The example shows requirement sources, examples of related requirements and to which aspects the designer should pay attention
