A [[computer programmer]] is a specialist responsible for writing or modifying the source code to implement the detailed plan.<ref name="pis-ch12-p507"/> A programming team is likely to be needed because most systems are too large to be completed by a single programmer.<ref name="se-ch10-319">{{cite book

Instead, it may lower the quality of the system.<ref name="se-ch10-319"/> To be effective, program modules need to be defined and distributed to team members.<ref name="se-ch10-319"/> Also, team members must interact with one another in a meaningful and effective way.<ref name="se-ch10-319"/>
