The advantages of using flowcharts in Presentations

First of all, we begin with the definition of what a data flow diagram is in the first place. A flow chart of data is a graphical representation of data flow in a process system or information. These diagrams can become a priceless resource and presenting, if used properly.

Usually this technique begins with a very high level of representation and the image projection of the overall business processes and continues to the lowest levels of the process through the presentation. This is often called top-down expansion. With this analysis, the audience can literally walk you through the process and see each discrete point as they lead them through the presentation. This is particularly useful with representatives of companies that have a stake in the workflow or process is being discussed. Often, they can not ever seeing the high level view of the process or flow data.

To begin, just start with a context diagram. This is usually a simple representation of the whole system, process or data flow that you are discussing. Then, follow with a flow chart of level 1, which provides an overview of the major functional areas of business. At this point, do not go into details. Maintain the level of a high-level diagram and begin to address all areas of interest that the public has an interest in. Make sure you are using terminology that makes sense for them. The easiest way to lose the audience is to use acronyms or terminology which may not affect.

Now that you have your diagram level 1, you are ready to create the Level 2 flowchart business. Continue to play back the layers of the presentation process go more in depth at every level. Typically, you want to have no more than four (4) layers deep. Any deeper and you lose the audience for sure. A good approach is to provide hand outs that participants can bring.

Identify existing business processes, using a technique like data flow diagrams, is an essential step in business process re-engineering, migration to new technology, or improving any workflow related to your business.
Here are some parts you need in your flowchart:
External entities

An external entity is a source or destination of a data flow that is outside of the process. This could be anything in which the data originates outside of the process. The symbol used is an oval containing a unique identifier and significant.

Process

A process shows a transformation or manipulation of data flows within your system. The symbol used is a rectangular box which usually contains three elements. The first is a number that appears in the top left hand corner.1

Firstly an identification number appears in the upper left. This is arbitrarily assigned to the high level and serves as a reference. Secondly, there must be an identifier that indicates where in the system, the process takes place. An example is a piece of hardware, or department. Finally, a descriptive title is at the center of the box. This should be a simple statement with a specific verb, for example 'keep a register of suppliers' or' need to find. "
Data Flow

A data flow shows the flow of information from the source to its destination. A data stream is represented by a line, with arrows indicating the direction of flow.

Data Store

A data store represents a location of information within the system:
It is represented by a rectangle open closed tight. An example would be a lot of bills or a queue in a system that stores the records before processing.
Flow resources

A resource flow shows the flow of physical material from any source to its destination.
The physical resources need to be identified and labeled.
Now you are ready to create an informative and engaging presentation .......
