Flow Chart in 7 QC tools | Process Flow Diagram 

 Flow Chart is also known by the Process Flow Diagram.
 It is a diagrammatic representation that illustrates the sequence of operations to be performed to get the desired result.


Flow Chart Definition:

 → Flow Chart is a diagrammatic representation that illustrates the sequence of operations to be performed to get the desired result.
 → As per Wikipedia, It is a type of diagram that represents an algorithm, workflow or process.
 → The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows.
 → It is used in analyzing, designing, documenting or managing a process or program in various fields


The use of Process Flow Diagram:

 → Planning a new project
 → Documenting a process
 → Managing workflow 
 → Also used for the auditing process.



Milestones:

 → 1960: The American National Symbols Institute (ANSI) set standards for Flow Charts and their symbols in the 1960s.
 → 1970: The International Organizations for Standardization (ISO) adopted the ANSI symbols in 1970.
 → 1985: The current standard was revised in 1985.

General Guideline for Flow Chart making:

 → The process needs to start from top to down, from left to right. 
 → Graph size needs to be the same.
 → Start symbol only appears once, but the end symbol can use more.
 → There is only one arrow path graph for the same path.
 → The line should avoid the cross, if need crossed should be used across the graph.
