Flowcharts allow you to draw a picture of the way a process works so that you can understand the existing process and develop ideas about how to improve it. Since humans are primarily a visual species, a picture of a process conveys information more efficiently than a written or verbal description.

Making a process visible also renders it easier to manage and captures the subtle interactions among components. Flowcharts can provide a step-by-step diagram for mapping out complex situations, such as programming or business workflow. There are many types of flow charts including swimlanes, such as cross-functional, opportunity or deployment flowchart. A high-level flowchart, showing six to 12 steps, gives a panoramic view of a process.

These flowcharts show clearly the major blocks of activity, or the major system components, in a process. High-level flowcharts are especially useful in the early phases of a project. A detailed flowchart is a close-up view of the process, typically showing dozens of steps. These flowcharts make it easy to identify rework loops and complexity in a process.

Detailed flowcharts are useful after teams have pinpointed issues or when they are making changes in the process. Flowcharts are diagrams that use shapes to show the types and flow of steps in a process.

The shapes represent different types of steps or actions. Terminal Symbol : Every flowchart has a unique starting point and an ending point.

The flowchart begins at the start of the terminator and ends at the stop terminator. Thus if there is any input to the program via an input device, like a keyboard, tape, card reader, etc. Similarly, all output instructions, for output to devices like printers, plotters, magnetic tapes, disk, monitors, etc. Process Symbol : A process symbol is used to represent arithmetic and data movement instructions in the flowchart.

All arithmetic processes of addition, subtraction, multiplication, and division are indicated in the process symbol. The logical process of data movement from one memory location to another is also represented in the process box. If there are more than one process instructions to be executed sequentially, they can be placed in the same process box, one below the other in the sequence in which they are to be executed. Decision Symbol : The decision symbol is used in a flowchart to indicate the point where a decision is to be made and branching done upon the result of the decision to one or more alternative paths.

The criteria for decision making is written in the decision box. All the possible paths should be accounted for.

During execution, the appropriate path will be followed depending upon the result of the decision. Flow : Flow links are solid lines with arrowheads that indicate the flow of operation. They show the exact sequence in which the instructions are to be executed. The normal flow of the flowchart is depicted from top to bottom and left to right. Connectors : In situations, where the flowcharts become big, it may so happen that the flowlines start crossing each other at many places confusing.

This will also result in making the flowchart difficult to understand. Also, the flowchart may not fit in a single page for big programs.Products Solutions Samples Buy. This site uses cookies.

This opportunity flowchart sample shows the steps involved in replacing engine oil process. The opportunity flowcharts are used in business process improvement to identify process steps which might be improved. An organization is only as good as its processes. To be able to make the necessary changes in an organization, one needs to understand the key processes of the company.

Identify the process to be improved based on a critical business issue : The identification of key processes can be a formal or informal exercise. The management team might select processes by applying a set of criteria derived from strategic and tactical priorities, or process selection is based on obvious performance gaps. It is important is to select the process es which have the greatest impact on a competitive advantage or customer requirement. Develop the objective s for the project based on the requirements of the process: The focus might be on quality improvement, productivity, cost, customer service or cycle time.

The goal is however always the same; to get the key process under control. Select the members of the cross-functional team: A horizontal cross-functional analysis is carried out by a team composed of representatives of all functions involved in the process. While a consultant or in-house staff person can do the job, the quality of the analysis and the commitment to change is far greater with a cross-functional team.

Develop a cross-functional process map for the process. Recommend changes organizational, in the process or in its execution : Categorize and prioritize the main problems and possibilities, evaluate alternative solutions.

The following is a basic overview, with descriptions and meanings, of the most common flowchart symbols - also commonly called flowchart shapesflow diagram symbols or process mapping symbolsdepending upon what type of diagram you're creating.

The table below lists the flowchart symbol drawing, the name of the flowchart symbol in Microsoft Office with aliases in parenthesesand a short description of where and how the flowchart symbol is used. Caveat: The descriptions given above are written from the perspective of someone using them to create process flow chartswhereas many of the flowchart symbols actually have their roots in the data processing diagrams and programming flow charts. So, not all the flowcharting shapes shown below may be relevant to your needs.

The flowchart symbol names in parentheses are common alternates for a given shape. Sometimes a flowchart shape can have more than one meaning, as with the Circle shape, which depicts a jump node in flow charts and inspection point in business process mapping. Other times, there are just multiple names for the same flow chart symbol - such as Terminator and Terminal Point.

The majority of flowcharts rely on just a few of the process-related symbols to do all the heavy lifting: TerminatorProcessDecisionDocumentand Connector.

In fact, if you use other flowcharting shapes, many people won't know what they are for, so you may want to add a symbol key to your flowchart. You might think that an expensive flowchart software package is required to make presentation-quality flowcharts.

It isn't. All the shapes used in this article were created in Microsoft Excel. FlowBreeze is an Excel add-in that automates the steps to create a flowchart.

I have some thoughts, but maybe I'm missing an elephant in the room? For my case of ad-hoc documenting a particular block of application logic, I decided to go with the flowchart diagrams.

More people in the company will be able to understand them. It might seem as a preference, but if we have a standardized language for describing software systems, Why do we use something else? This can lead to bad habit of overusing flowcharts.

UML Activity Diagram Tutorial

Activity diagrams are really simple. But if you decide to describe a more complicated aspect of the system or try to change the part you are describing, you might have to switch anyway.

So just use UML and prevent confusion in the future. As you note, Activity diagrams inherently can include concurrency and timing. If you look at this example cribbed from Wikipedia, shown below, you can observe the section with two heavy horizontal bars, and two parallel activities of "present idea" and "record idea".

That is read as "start these activities in parallel, and continue only when both are complete. Practically, using activity diagrams lets you think clearly about concurrent processes.

I think you'll find that anyone who can read a flowchart will quickly adapt. According to the Agile Modeling site:. In many ways UML activity diagrams are the object-oriented equivalent of flow charts and data flow diagrams DFDs from structured development. From IBM :.

However, flow charts do not include And states, and flow charts for operations cannot receive events. Probably this is why flow charts are easier to understand because activity diagrams have the notion of object-oriented development and concurrency. You can generate source code from UML, and vice versa; hence the "standardized" characteristic you talked about. UML in itself is used to share your understanding.

Share the understanding in a standardized way. Since your case is ad hoc and the primary usage of an UML diagram is to provide an informal sketch, activity diagram can be used here.

But so can flow charts as there are no parellism involved here.Large processes are often composed of subprocesses that can be thought of as self-contained units that can be diagrammed on their own page. That way, you can make the overview diagram cleaner by using a single shape to represent the subprocess and hyperlinking it to the detailed drawing.

To jump to the subprocess page, press the CTRL key and then click the linked shape, or right-click the shape and then click the named hyperlink. Subprocesses can be on separate pages in a single document, or, if you have subprocesses that you might use in multiple diagrams, you can create the subprocess diagram once and save it. Then you can link to that diagram from subprocess shapes in other diagrams. On the Process tab, in the Subprocess group, click Create New.

Visio adds a new page to the diagram for the subprocess, and creates a hyperlink from the selected shape to that page. On the Process tab, in the Subprocess group, click Create from Selection.

The selected shapes are moved to a new page, and a new shape is added to the source diagram to represent the subprocess. The new shape is linked to the new page. If the process overview is a cross-functional flowchart, the new subprocess page will include swimlanes and phases that match the overview page. On the Process tab, in the Subprocess group, click Link to Existing. A menu opens that lists the pages in the diagram, and also gives the option to link to a different document. Click the page you want to link to, or click Browse to Other Document to link the shape to a different document.

Right-click the shape, and then click Edit Hyperlinks. In the Hyperlinks dialog box, click Delete to remove the hyperlink that is currently selected in the list.

If you don't have an existing hyperlink, click New to create a new hyperlink, and click Browse next to the Address box to select the diagram to link to.

Click Browse next to the Sub-address box to specify the page to link to. Select the shape you want to add the link to, or add a new shape to the page.

Lucidchart is a collaborative workspace that brings remote teams together in real time. UML is extremely useful for visualizing and documenting software systems, but the terminology can be somewhat overwhelming for someone unfamiliar with UML. If you're new to UML diagramming softwarethis guide will help you get started.

Want to make a UML diagram of your own? Try Lucidchart. It's quick, easy, and completely free. The Unified Modeling Language includes several subsets of diagrams, including structure diagrams, interaction diagrams, and behavior diagrams.

Activity diagrams, along with use case and state machine diagramsare considered behavior diagrams because they describe what must happen in the system being modeled. Stakeholders have many issues to manage, so it's important to communicate with clarity and brevity. Activity diagrams help people on the business and development sides of an organization come together to understand the same process and behavior.

Activity diagrams present a number of benefits to users. Consider creating an activity diagram to:. Before you begin making an activity diagram, you should first understand its makeup. Some of the most common components of an activity diagram include:. In Lucidchart, actions are symbolized with round-edged rectangles. It includes a single input and two or more outputs. The start node is represented by a black circle. The end node is represented by an outlined black circle. Diagramming is quick and easy with Lucidchart.

Represents the beginning of a process or workflow in an activity diagram.Activity diagram is another important diagram in UML to describe the dynamic aspects of the system.

Activity diagram is basically a flowchart to represent the flow from one activity to another activity. The activity can be described as an operation of the system. The control flow is drawn from one operation to another.

This flow can be sequential, branched, or concurrent. Activity diagrams deal with all type of flow control by using different elements such as fork, join, etc.

The basic purposes of activity diagrams is similar to other four diagrams. It captures the dynamic behavior of the system. Other four diagrams are used to show the message flow from one object to another but activity diagram is used to show message flow from one activity to another. Activity is a particular operation of the system.

Activity diagrams are not only used for visualizing the dynamic nature of a system, but they are also used to construct the executable system by using forward and reverse engineering techniques. The only missing thing in the activity diagram is the message part. It does not show any message flow from one activity to another. Activity diagram is sometimes considered as the flowchart.

Although the diagrams look like a flowchart, they are not. It shows different flows such as parallel, branched, concurrent, and single. Activity diagrams are mainly used as a flowchart that consists of activities performed by the system. Activity diagrams are not exactly flowcharts as they have some additional capabilities. These additional capabilities include branching, parallel flow, swimlane, etc. Before drawing an activity diagram, we must have a clear understanding about the elements used in activity diagram.

The main element of an activity diagram is the activity itself. An activity is a function performed by the system. After identifying the activities, we need to understand how they are associated with constraints and conditions.

Once the above-mentioned parameters are identified, we need to make a mental layout of the entire flow. This mental layout is then transformed into an activity diagram.

Following is an example of an activity diagram for order management system. In the diagram, four activities are identified which are associated with conditions.

One important point should be clearly understood that an activity diagram cannot be exactly matched with the code. The activity diagram is made to understand the flow of activities and is mainly used by the business users. After receiving the order request, condition checks are performed to check if it is normal or special order.

After the type of order is identified, dispatch activity is performed and that is marked as the termination of the process. The basic usage of activity diagram is similar to other four UML diagrams.

The specific usage is to model the control flow from one activity to another. This control flow does not include messages. Activity diagram is suitable for modeling the activity flow of the system.
