Flowcharts can be quickly created in many computer software programs; even recent versions of Microsoft Word and PowerPoint contain Smart Shapes that allow users to rapidly insert a flowchart into a document of presentation. Specialist Flowchart Diagramming software also exists but for sheer versatility and the ability to connect data to shapes I would put my money on Microsoft Visio. It has a huge range of ready-made stencils containing all the shapes you could possibly need (and the ability to create your own if you wish), and very slick automatic connection features. Visio also allow a flowchart that dexcribes one process to become part of a larger process and to integrate with it via a hyperlink from a button on the drawing page.
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).
Many departments have established business rules based on guiding principles and philosophies that may have been created years before. Because there has been no initiative in documenting these procedures, chances are that there are many rules still in place that are causing unnecessary barriers and redundancies that add to the purchase order cycle time.A flowchart is a sequence of graphical symbols and shapes that can be used to help subject matter experts visually walk through their processes and validate those rules for accuracy and relevancy based on current business needs.
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.
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.
