We will illustrate the process of an online shop that sells goods. Capture the Current Process in As-is Process It provides a robust means to capture the current business process, design enhancement and identify the enhancement between the current and enhanced processes. In this tutorial, we will be using Visual Paradigm to create BPMN-compliant business process diagrams. By creating a To-Be business process, organizations can prioritize and focus on the most critical changes necessary to achieve their goals and close the gaps between the current and desired states. The purpose of a To-Be business process is to provide a clear picture of what the future state of the organization will look like, and what steps need to be taken to achieve it. It serves as a roadmap for change, identifying where the organization needs to be in order to achieve its goals. What is a To-Be Process?Ī To-Be business process outlines how a company's process, culture, and capabilities will appear in the future. By understanding how work is currently being performed, organizations can develop strategies to eliminate bottlenecks, reduce waste, and enhance overall business processes. The purpose of an As-Is business process is to provide a baseline for identifying areas for improvement, optimizing the use of resources, and ultimately increasing efficiency and productivity. It outlines how work is currently performed and how information flows through the organization. Input and output data flows are labeled based on the type of data or its associated process or data store, and this name is written alongside the arrow.An As-Is business process is a detailed overview of the current state of a company's process, culture, and capabilities. This data could be electronic, written or verbal. Output flows would be data retrieved from the store.ĭata Flow – Movement of data between external entities, processes and data stores is represented with an arrow symbol, which indicates the direction of flow. Input flows to a data store include information or operations that change the stored data. Data stores could consist of files held long term or a batch of documents stored briefly while they wait to be processed. Processes are typically oriented from top to bottom and left to right on a data flow diagram.ĭata Store – A data store does not generate any operations but simply holds data for later access. In Gane-Sarson notation, a rectangular box is used and may be labeled with a reference number, location of where in the system the process occurs and a short title that describes its function. This symbol is given a simple name based on its function, such as “Ship Order,” rather than being labeled “process” on a diagram. Since they transform incoming data to outgoing data, all processes must have inputs and outputs on a DFD. Process – An activity that changes or transforms data flows. They can represent another system or indicate a subsystem. Since they are external to the system being analyzed, these entities are typically placed at the boundaries of the diagram. These data flows are the inputs and outputs of the DFD. If you’re using DFD software, it will likely dictate which set of symbols are available to use.Īll data flow diagrams include four main elements: entity, process, data store and data flow.Įxternal Entity – Also known as actors, sources or sinks, and terminators, external entities produce and consume data that flows between the entity and the system being diagrammed. Because DFD symbols vary, it’s important to be consistent with whatever notation you choose in order to avoid confusion. Another variation is the symbol used for data stores-Yourdon and Coad uses parallel lines while Gane and Sarson notation uses an open-ended rectangle. For example, Yourdon and Coad notation uses circles to represent processes, whereas Gane and Sarson notation use rectangles with rounded corners. There are some differences in style between the notation types. The two main types of notation used for data flow diagrams are Yourdon-Coad and Gane-Sarson, both named after their creators, all experts who helped develop DFD methodology: Ed Yourdon, Peter Coad, Chris Gane and Trish Sarson.
