I recently overheard a Business Analyst say there was more to systems architecture than drawing boxes and arrows on a piece of paper. This may be true to a degree, but the ultimate deliverable of any engineering/architectural practice is a set of drawings from which to build a product. Architects and engineers do not spend all of their time drawing diagrams; for example, they have to specify requirements and analyze such things as the stress of components to determine the suitability of materials for use in design. But aside from this, the end result of engineering or architecture, their deliverable, is a set of drawings, be it a blueprint, a floor plan, wiring diagram, plumbing, or a set of flowcharts.
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.
A flowchart could be defined as a pictorial representation of a process in which the steps are symbolized by shapes - in other words a diagram that explains the steps in a procedure. Each shape should link to its neighbour by a connector line, and often these have arrow heads to describe the direction of flow.
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).
Well, flowcharts can be used to analyze, design, document or manage a process in a wide variety of fields. Examples could include a Recruitment or Accounting process, the logical procedure within a piece of software, or a process in an organization such as Health & Safety, Equal Opportunities, Conciliation & Arbitration or Social Services. There are several derivatives of the basic flowchart including the Workflow Diagram,
In addition to diagramming techniques, engineers and architects have found it useful to develop models and prototypes to evaluate the overall physical aspects of their design. These are useful but let us not forget they are all ultimately based on a design of some kind (boxes and lines). From the models and prototypes, designs can be adjusted as required.
