Accurately estimating a software development effort is a challenge that
has a major impact on the project’s organisation and schedule. Up to
now, the estimate often relied mainly on past experience. CETIC has
developed expertise in this area based on COSMIC (ISO/IEC 19761), a
widely used method for estimating software functional size. The COSMIC
function point estimation method is based on objective criteria. It allows
measures to be repeated and it is applicable to requirements documents
early in the software life-cycle. The functional size generated by COSMIC
is then converted into development effort based on the ISBSG project
database. CETIC can also help companies implement their own internal
reference effort database.
CETIC initiated new transfers of the COSMIC software functional size
estimation methodology in companies from the medico-social and financial sectors. CETIC continued to support Siemens IT Solutions and Services, Belgium, to increase its expertise with this method and to apply
it to specific projects.
