Functional Role: Because position titles vary greatly for officials performing the same role among different municipalities, Functional Role clarifies which official performs a particular key function within each city or town. As defined here, only one individual can perform a particular functional role in a given community, e.g. only one person can be the town manager/administrator (CEO/Manager/Administr.) and only one person can be the principal person who directs daily work in the assessing department (Assessment Director).
