Purpose of Flowcharting
Show the steps involved within the
process.
Determine where delays are, their causes,how to reduce them.
Aid in communication of thoughts, ideas,
and procedures.

!he terminator sym"ol mar#s the starting or endingpoint of a system.
!he delay sym"ol mar#s a delay in the system
showing that the ne$t occurrence is not instantaneous.
!he decision sym"ol mar#s a decision or "ranchingpoint. Decisions are always "inary %i.e. &yes' or&no'(.
!he process sym"ol can represent a single step or anentire su")process.
*ines indicate the se+uence of steps and the directionof flow.

Developing a FlowchartHere is an e$ample of flowcharting in a clinic.
hec# -n
A flowchart alwaysstarts with a
terminator, usually
the terminator is a
process however, it
can sometimes "eassociated with a
decision that has
only one result.

Decisions are important in determining what path to
follow as a result of previous events. -n the e$ample
a"ove, as long as the info has not "een gathered, the
patient continues to wait in the waiting room.

terminator, designating the end of the
process. However, occasionally, the
flowchart will end with a decision if it is
necessary to complete the process again
