<programming, unit> (DSI) One line of source code (LOC)
developed by a project.
DSI is the primary input to many tools for estimating software
cost. The term "delivered" is generally meant to exclude
non-delivered support software such as test drivers. However,
if these are developed with the same care as delivered
software, with their own reviews, test plans, documentation,
etc., then they should be counted. The "source instructions"
include all program instructions created by project personnel
and processed into machine code by some combination of
preprocessors, compilers, and assemblers. It excludes
comments and unmodified utility software. It includes job
control language, format statements, and data declarations.
