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
