It is used to model work that is done by somebody who the engine does not need to know of and is there no known system or UI interface. For the engine, a manual task is handled as a pass-through activity, automatically continuing the process at the moment the process execution arrives at it. With Visual Paradigm, you can draw your own BPMN diagram by using different kinds of activities. In this article, we will explain the different kinds of BPMN 2.0 activities you can use in modeling a business process with BPMN. No matter you want to learn BPMN or to perform business process mapping in your commercial project, you will find Visual Paradigm useful. BPMN introduces a set of graphical notations that can be easily understood by everyone, from technical people such as business analysts, software developers, and data architects to business stakeholders such as the end users and other business stakeholders. This helps people communicate process workflow design ideas effectively. An Activity is can be atomic (Tasks) or decomposable (Sub-Processes). There are basically three BPMN activity types: You create a task when the activity cannot be broken down to a finer level of detail. Generally, a person or applications will perform the task when it is executed. Here is a list of BPMN 2.0 task type: A Service Task is used to represent the publishing of answer on Twitter, through the web service they provided. The Task is completed once the Message has been sent. The Task is completed once the message has received. The task Receive Pickup Request is activated only when the message is received. In this case, it’s the pickup request. User Task is used to represents the order approval task, which is done by the buyer (i.e. human performer) through interacting with the shopping system (i.e. software application). The tasks about sign-off are both manual task that are performed without the aid of any process execution engine or software systems. http://www.armagedonspedycja.pl/files/breadman-plus-tr700c-manual.xml

It is expected that a business rule engine will be used in analyzing the data collected from the survey, and producing the result of analysis in return. The task defines a script that the engine can interpret. When the task begin, the engine will execute the script. The Task will be completed when the script is completed. A Script Task Check Credit is used in reviewing the credit status of applicant, which is done by executing a pre-written script. Generally, we create BPMN diagrams to communicate processes with others. To facilitate effective communications, we really do not want to make a business process diagram too complex. By using sub-processes, you can split a complex process into multiple levels, which allows you to focus on a particular area in a single process diagram. We will go cover each of them in the sections below. It allows you to create a reusable process definition that can be reused in multiple other process definitions. It consists of a Call Activity Register that references the Register task defined in a global process. Try out Visual Paradigm.

Regardless of your specific project or your industry, there are a lot of common questions about using BPMN. In our experience, most of the BPMN examples below are useful to any BPMN user. http://agro-vostok.ru/userfiles/breadman-plus-tr-800-instruction-manual.xml

Since then, we have been participating in the development of BPMN 2.0. We will use the example of creating a bill. In order to create the bill, a discount needs to be computed. The sum of the order and the customer type are the relevant criteria to compute the discount. In this example, the process has two steps. A discount is computed before the bill is created. The result is a very simple process. For the rules decision tree, for every additional criteria, the cardinalities will grow exponentially. That is not what we want in a BPMN model. We are using a simple example. If one credit check of a customer is running, we do not want another credit check for the same customer to be performed at the same time. The problem of the signal is that it functions as a broadcast and does not address any specific instance. So, strictly speaking, the customer is ignored and all waiting instances catch it. That induces a second data request before the end of the instance. However, this is the correct way to solve the problem that occurs in the signal event solution. The instance itself checks periodicity if it can proceed to the credit check. The downside is that this might cause delays and overhead due to the loop. A Process Engine should ensure that both approvals are fulfilled before the request is approved. The manual steps that are performed by the two approvers should also be modeled in the BPMN diagram. The approval decision is performed using a portal with a tasklist. Here are some examples: This way, we can clearly define who is in control of which process. These user tasks correspond to the tasks which are shown in the tasklist of the 1st and the 2nd approver. These message flows encapsulate the manual steps which the approver needs to perform in order to complete the user task. The service works as follows: The customers can ask for legal advice whenever they need it. The lawyer provides the requested advice and puts the billable hours on the customer’s time sheet. http://www.drupalitalia.org/node/75419

When the month is over, the lawyer’s accountant determines the billable hours based on the time sheet and creates the invoice. It’s not the steps of the processes that are difficult, it’s the structure of the diagram. The Monthly Invoicing process is only performed once a month. Therefore, these two processes should be modeled as separate pools. Our ability to model such a data-related connection is very limited in BPMN. This is due to the fact that BPMN is focused on control flow rather than on data flow. It would mean that for every provided legal advice an invoice is sent once the month is over. This way of modeling is wrong in most cases. After the user task is completed, additional information might be required. If that is the case, the process engine sends an information request either to another user (solution 1) or to a technical service (solution 2). One of these channels is a marketplace. Within certain intervals of time, the orders from the marketplace are fetched as a batch. Every order in this batch needs to be validated before being imported into the ERP System. We sometimes call it a 1-to-n problem. One process instance (Import of Orders) results in many single process instances of another process (ERP System). Typical constructs are multi instance or loops that start other processes using messages (message flows). Therefore, the user tasks needs to be reassigned as soon as the current assignee is unavailable, e.g., due to leave or sickness. Sometimes the pizza delivery screws up and the delivery takes longer than 30 minutes. Then we complain to the delivery service. After that, we give them another 20 minutes to deliver the pizza. If they do not make it in time, we give up and cancel our order. Timers are modeled separately, followed by their corresponding escalation activities. Since we use a non-interrupting attached timer event, this solution is more flexible when it comes to multiple complaints (e.g. http://danijel-prevod.com/images/bpl-studioline-21-manual.pdf

, we want to complain every 5 minutes until 50 minutes are over). If it comes to n-step escalation then you will need this generic approach to avoid huge diagrams. We do not see the actual duration of the timers, as a single timer is used for both durations. The better the layout, the higher the degree of understanding. That is what we want to achieve when we create process models. Bear in mind that it always makes sense to invest some extra time in optimizing the layout in a way that most crossing flows are eliminated. Start events should always be labeled with an indication of the trigger of the process. End events should be labeled with the end state of the process. This label should indicate the name of the process and the role that is performing it. This forces the modeling person to focus on what is really done during the task. The outgoing sequence flows should be labeled with the possible answers to these questions (conditions). The better the layout, the higher the degree of understanding. That is what we want to achieve when we create process models. People tend to interpret task sizes although they do not have any semantics in the BPMN standard. Save your spot today - it's free! Watch On Demand Video Contact Us Lanes always exist in a pool, and the lane boundaries represent process boundaries from start to end. To BPMN, the pool represents a higher-ranking instance compared to its lanes. It behaves like the conductor of an orchestra, and so this type of process is called “orchestration.” Many experienced process modelers have problems with this way of thinking. They would prefer to model a process sequence like that shown below on the assumption that no almighty conductor exists in their company, and that individual process participants have to coordinate and cooperate on their own: You assign each task manager a separate pool, and the process passes from one to the next as a message flow as shown in below. www.medicalart.com.tr/wp-content/plugins/formcraft/file-upload/server/content/files/1627f67120d772---browning-1922-manual.pdf

In principle, this creates four independent conductors. These have control over their respective mini-processes, but they can’t do anything other than to send messages that trigger their successor processes: Even though BPMN lanes look very much like those of other process notations, they represent an entirely different way of thinking, which we attribute to BPMN’s origin in the world of process automation. In that world, the process engine controls all tasks in the process, even though different task managers may execute them. So the process engine equates to the mysterious, almighty process conductor. That’s almost exactly the task of a process engine, except that these services are not only fully automated web services; they also can be tasks executed by human process participants as directed by the process engine. What does that signify, however, for purely functional process modeling, in which you also describe processes not controlled by such a process engine. There’s no general answer to that question. That’s traditional, and it’s a pragmatic solution during, say, a transitional period that allows your co-workers to adapt. In the medium and long terms, however, avoiding pools denies you a powerful device for increasing the significance of process models. One thing to remember is that if you strive to harmonize your functional and technical process models to achieve a better alignment of business and IT, you inevitably face this type of process modeling whether you use BPMN or not. Presumably, it looks like here: As soon as we receive an order, we bake the pizza. Our delivery person takes it to the customer and collects the money, whereby the process completes successfully. We can try to model this interaction by means of a pool and lanes as in here: It is impossible to differentiate the two visually. contactlens88.com/imagedepot/upbank/files/casio-data-manager-6_0-manual.pdf

Strictly speaking, the diagram is not semantically correct because message events always refer to messages received by the process from outside, and that’s not the case here. Both processes in the combined representation would look just as they did before, but now they connect through message flows. BPMN calls this form of visualization a collaboration diagram. It shows two independent processes collaborating. The first one comes from the “inquire at delivery service” task; the second one connects to the “collect money” task. The rationale behind the first one is that our inquiry does not influence the sequence flow of the deliverer. The pizza service may provide information or speed up its order processing in anticipation of a new order, but the baking, delivering, and collecting of money doesn’t change just because an inquiry came in. As for the “collect money” messages, there’s a flaw in the model of the customer process: we have to pay for the pizza before we eat it, and that task is still missing. We added it to the diagram below, and now we can connect the message flows directly to the “pay for pizza” task. We may know the processes of our own company, for example, but not those of a partner company. As long as our partner and we adhere to agreed-upon interfaces, such as receiving or sending certain messages, things can still operate smoothly. As customers of the pizza delivery service, we expect the deliverer to: Maybe he bakes and then delivers the pizza; maybe when he’s out of supplies, he gets another pizza service to bake the pizza and deliver it. In modeling such cases, we can hide the deliverer’s process and collapse the pool: Now we see only the messages to be exchanged, assuming that we label the arrows to give us the general idea. The downside is that we can’t recognize interdependencies any more.In BPMN, you can answer this question with lanes. {-Variable.fc_1_url-

We can derive the following process description from the assignments: If Christian is hungry, he chooses a certain recipe. Depending on what Christian chooses, he can either take care of it himself (cook pasta), or he can get his roommates on board. If the latter, Falko cooks steak and Robert prepares salad. In the end, Christian eats. The three lanes (Christian, Falko, Robert) are united in one pool designated “flat-sharing community.” In the example, lanes equate to people, but this meaning is not specified by BPMN. You can designate the lanes as you like. In practice, lanes are often used to assign: Positions in the primary organization, for example, accounting clerk. Primarily, task types are intended to model processes that are technically executable. Task types are applied infrequently in practice. We know from experience, however, that task types can be particularly useful when modeling engineering requirements. Markers can be combined with the assigned types. Perhaps we suggest various dishes to our dinner guests until everyone agrees. Then, we can prepare the meal: Programmers know the principle as the “do-while” construct. We can also apply a “while-do” construct, however, and so check for a condition before the task instead of afterward. This occurs rarely, but it makes sense if the task may not execute at all. You can store this condition as an attribute in a formal language of your BPMN tool as well. That makes sense if the process is to be executed by a process engine. If for example we live in a flat-sharing community and the roommates feel like eating pizza, the “choose pizza” task must be repeated for each roommate before we can order. You’d sit together and pass a menu around until finally everyone has made a decision. It is much more efficient for all roommates to look at the menu at once, and they choose a pizza together. You can model this process using the “multiple task” (see below). www.zav-mito.si/wp-content/plugins/formcraft/file-upload/server/content/files/1627f6734aae9b---browning-1919a4-manual.pdf

A multiple task instantiates repeatedly and can be executed in sequence or in parallel, with the latter being the more interesting case. How does your company check invoices for group orders, such as for office supplies. Do you forward the invoice from one employee to the next, so that each person can sign off on the items he or she ordered, before you pay the invoice. If so, you live in a flat-sharing community, and you urgently should consider optimizing your process. Automating invoices is still one of the top BPM projects, and the top goal of such projects often is one of parallelization. The compensation task type is applied exclusively in the context of a compensation event. Accordingly, it is integrated in the process diagram only by associations, never by sequence flows. In this case, both markers are placed in parallel. As with the other markers, the compensation can be combined with the task types already introduced. A manual compensation task that repeats until it succeeds or that executes repeatedly and in parallel as far as possible, is therefore eminently practical. When modeling your process landscape, you don’t have this luxury. You have to rough out your processes so that you can get the general ideas in place and recognize correlations. Then you have to develop a detailed description, so that you can analyze exactly where the weak points are or how you’ll have to execute the process in practice. The possible top-down refinements or bottom-up aggregations mark the difference between true process models and banal flow charts, between sophisticated BPM software products and mere drawing programs. A subprocess describes a detailed sequence, but it takes no more space in the diagram of the parent process than does a task. Both tasks and subprocesses are part of the activities class and are therefore represented as rectangles with rounded corners. www.bascoy.com/userfiles/files/casio-d-20ter-manuale.pdf

The only difference is the plus sign, indicating a stored detailed sequence for the subprocess: That depends most on how your BPMN tool supports the following options for connecting subprocesses with their parent processes: If your BPMN tool displays the process model in a web browser, for instance, clicking on the symbol would open a new page to display the detail diagram. Expanding in the process diagram of the parent process: The activity with the plus sign is called a collapsed subprocess. The plus sign suggests that you could click on it and make the subprocess expand. The BPMN specification provides for this option, though not all tool suppliers implement it. The diagram below shows how the subprocess was directly expanded in the diagram of the parent process. A tool supporting this function enables you to expand and collapse the subprocess directly in the diagram, respectively, to show or hide details. Expanding the subprocess requires that all the adjacent symbols in the diagram shift to make room. This can result in sluggish performance with a complex diagram, and it can be visually nasty. The most important thing is that your tool provides for linking and that you can usefully navigate through the diagrams. In other words, it supports the first option above. Yes, it can be helpful to have your subprocess modeled and expandable directly from the parent process. That means process segments remain localized, and you can attach events too. This is, however, the less important option. The next sequence flow starts at the right edge. This means that sequence flows are not allowed to exceed the boundaries of the subprocess, which not every beginner knows, and which becomes a problem when a subprocess expands. Visualize a token that behaves as follows: The token runs through the task and arrives at the subprocess, which causes the parent process to create an instance of the subprocess. Within the subprocess, a separate token is born which runs through the subprocess from the start to the end event, but the token of the parent process waits until the subprocess completes. When the subprocess token arrives at the end event, it is consumed, which completes the subprocess. Now the token of the parent process moves to its own end event. You could just as easily have a parent process as a subprocess, or you could model further subprocesses on the level of a defined subprocess. How many levels you use and the level of detail you apply to model them is up to you. BPMN doesn’t specify this, and there can be no cross-company or cross-scenario cookbook to define levels. Participants in our BPMN workshops don’t like this, but there’s no point in hiding the fact nor attempting to explain it away. In the following chapters, we work often with subprocesses in explaining our best practices, but the truth is the number of refinement levels and their respective levels of detail is always situational. It depends on the organization, the roles of the project participants, and the goals for the process you’re modeling. The same events can be attached to subprocesses as well, which opens up a wide range of opportunity in process modeling. As shown in the diagram below, we can represent how a spontaneous dinner invitation leads to canceling our cooking process. In the process shown, however, we could ignore the invitation if our meal had already been prepared and we are already eating it: With error, cancellation, and escalation events, however, the subprocess reports these events to the parent process. This isn’t as abstract as it may sound. Because item procurement is a global subprocess, it triggers an error event to tell the parent process that something went wrong. In business terms, this may mean that the customer who wanted to buy the item tells a salesperson that his or her order failed because the item is out of stock. While the disappointed customer must be informed within the scope of the order process, it is sufficient for the stock maintenance process to delete the item from the catalog. The respective parent processes decide what circumstances require canceling the subprocess and what happens next. That’s a principle that you can use to build flexible and modular process landscapes. But we also use the signal event to let the subprocess communicate things other than errors to the parent process. Primarily, this is because we can’t model this type of communication with message events. BPMN assumes that we always send messages to other participants who are outside of our pool boundaries; the communication between parent and subprocess doesn’t fit that mold. We don’t use signal events for directed communication, but rather to broadcast information akin to advertisements on the radio. The subprocess can use an escalation event to report directly to the parent process, and the message won’t be regarded as an error message. Also, the parent process can receive and process messages from escalation events without canceling the subprocess because non-interrupting intermediate events can be attached: In version 2.0, BPMN maintains this differentiation in principle, but it is defined differently. A subprocess now is embedded intrinsically, and it can be reused only by defining it as a global subprocess, and then referencing it by means of a call activity. We therefore refer to embedded subprocesses and global subprocesses in the following. An embedded subprocess cannot contain pools and lanes, but it can be placed within the pool or the lane of the parent process. Furthermore, an embedded subprocess may have only a none start event; start events such as messages or timers are not permitted. An embedded subprocess has essentially nothing more than a kind of delimited scope within the parent process, which may serve two goals: We deal with this option later. There are a great many subprocesses that, in practice, are used over and over. A good example is the procurement of an item because a customer ordered it or you need to re-stock supply. Another example is invoicing because you’ve delivered or repaired an item as shown in the diagram below. In the example, notice that call activities differ from regular activities by their considerably thicker borders: You can think of the participant responsible for a subprocess as a service provider for various parent processes. It is a like a shared service center. BPMN assumes that embedded subprocesses can read all the data of the parent process directly, but an explicit assignment is required for global subprocesses to be able to read it. That may seem like merely a technical aspect at first, one that modelers and the consumers of their models care to know about but won’t wish to bother with. After some consideration, however, you may see the impact this difference makes on the organization. Consider this: When your accounting department wants to issue an invoice for a repair, it always needs: Accounting will want the data in a standard format, won’t it. This corresponds well to what BPMN calls required data mapping between parent processes and global subprocesses. (Do you notice how often these weird techie issues correspond to the organizational needs and expectations of a process?) BPMN simply forces us to formalize many matters that seem self-evident, or that remained unconscious or forgotten in the process design. Formalization is our best chance of keeping up in a fast-changing environment with ever more complex processes. Recognize it by the tilde character as shown in the diagram below: You could say that the “barely structured” nature of what happens inside this subprocess reduces the whole idea of process modeling to an absurdity because what happens and when are the things we most want to control. On the other hand, this is the reality of many processes, and you can’t model them without representing their free-form character. Frequent examples are when a process relies largely on implicit knowledge or creativity, or when different employees carry out a process differently. You can use the ad-hoc subprocess to flag what may be an undesirable actual state. Doing so could be a step on the path to a more standardized procedure. We locate an event subprocess within another process or subprocess. Recognize them by their dotted-line frames. For event subprocesses, there can be interrupting (continuous line) and non-interrupting (dashed line) events. This is the same differentiation made as for attached intermediate events. Depending on the type of start event, the event subprocess will cancel the enclosing subprocess, or it will execute simultaneously. You can trigger non-interrupting event subprocesses as often as you wish, as long as the enclosing subprocess remains active. This starts the “dinner preparation” subprocess of choosing a recipe and then preparing the meal. While we are doing that, the telephone rings. Another guest invites himself to dinner. Spontaneous as we are, we just increase the amount of food or set another place at the table without interrupting the meal preparation. If an accident happens during preparation, however, the error immediately triggers the interrupting event subprocess for remedial action. We order food for delivery. When this event subprocess completes, we exit the enclosing subprocess through the regular exit and attend to eating the meal. In the top left corner, we also have the start event triggering the subprocess. In our simple example, we want to go into the details of cookery. Driven by hunger, we think about what we are going to cook today. We only know three recipes, so we choose one. We can either cook pasta or cook a steak or prepare a salad. The point of decision on what to do next is called gateway. We decide based on available data (the chosen recipe) and we follow only one of the paths, which is a data-based exclusive gateway. We abbreviate “exclusive gateway” as XOR. You have to determine facts and needs before reaching a gateway. This is our convention, which has proved its value in our projects. Possible answers go on parallel paths after the gateway, which is how the BPMN specification shows them. We always work with XOR gateways as follows: Model the task that requires a decision for the XOR gateway. We always use the version with the X because it seems less ambiguous. If you want salad no matter what, you could model it as we have done in this diagram: Congratulations: you’ve just analyzed your first process based on key data! Insufferable! You’re really hungry, but what can you do. The appropriate symbol is the parallel gateway, or the “AND gateway” for short, as shown in here: In contrast to the example shown before, it is also not imperative that you prepare the salad before starting other tasks. Parallel preparation does, however, reduce our total time by 10 minutes. It is classic process optimization to make tasks parallel as much as possible. What happens if we instantiate the process, and we decide in favor of pasta. The token is generated and then cloned as always at the AND split. As soon as we finish preparing the salad, the token passes through the XOR merge and “eat meal” executes. Five minutes later,”cook pasta” also completes. Its token passes through the XOR merge and “eat meal” executes again. That’s not the behavior we wanted. It’s easy to understand that progress depends on waiting for another token to reach an OR merge. It can be harder to trace the synchronization rules with complex diagrams that sprawl across several pages. This gateway does not route based on data, but rather by which event takes place next. To understand the benefit, consider the process shown below: We order pizza and wait for it to be delivered.
