Each flowchart should ideally begin with a Terminator shape, from which the next step should be linked. Each shape should be indicative of a specific stage in the process and there are conventions for each of these, the most common being the rectangular "Process" shape. Many others exist, however, including shapes representing Data, Documents and Decisions. Decision shapes are diamonds, each of the four corners (or nodes) being either a link from the preceding shape or action to be taken in the next stage depending on the decision.
Many of us use flowcharts in our daily work - indeed the creation and deployment of a flowchart is one of the most common tasks in business today. But what do we mean by a flowchart, and what is it supposed to do?
If your organization is looking for ways to reduce costs, the purchase order chain is one area that can be made more efficient. If the purchasing department learns how to draw a flowchart depicting the as is for each department, the overall effort could help reduce costs by eliminating redundant approval processes and mistakes.
In terms of the Information Systems industry, flowcharts have been used for years, well before the introduction of the commercial computer in business. Originally they included process diagrams; later they were used by programmers as a convenient means to document program logic. Such flowcharts typically made use of ANSI standard flowcharting symbols. But as the Structured Programming movement flourished in the late 1970`s, ANSI symbols were considered archaic, and many new types of diagramming techniques emerged, including Bubble Diagrams, Data Structure Diagrams, E/R Diagrams, HIPO, VTOC, etc. (anybody remember Nassi-Schneiderman Charts?). I could argue the pros and cons of the various techniques but that is not the point. What is important is that all of these diagramming techniques acknowledged documentation as an inherent part of the design process.
Such drawings basically consist of boxes and arrows. Boxes (be it squares, rectangles, polygons, circles, etc.) represent tangible objects and lines represent relationships between such objects. Flowcharts are similar; here, boxes represent specific types of processes or decisions or objects such as inputs/outputs/files, and lines represent dependencies between them (comes from/goes to).
Helping an organization map out processes can be a challenging task unless you know how to create sample flowcharts. When attempting to get subject matter experts to redefine their business processes, it is imperative to help them identify gaps or redundancies in their current as-is process.
