This post is a part four of the series about token and process flows in BPMN.
So far, we covered the simple flow (part 1), situations where only one of the alternative paths could be selected (part 2), as well as cases when all paths outgoing from a parallel gateway need to complete before the process can continue after the merge (part 3). Now, it’s time to tackle more sophisticated situations.
Inclusive gateways (commonly called OR) can be used to show that certain paths will always happen and others only sometimes – depending on certain conditions. You could say that OR gateway behaves like a (compact) mix of XOR and AND gateways.
It’s easy to recognize the OR gateways since they are diamonds with a circle inside (you can think that this marker is a slightly distorted “O”).
Let’s start by comparing OR gateway with XOR.
For XOR gateway you could have many paths outgoing from the gateway. The same applies to OR gateway – there can be 2, 3, or more paths.
Now, let’s take a look at the conditions on the outgoing paths.
For XOR gateway token would take a first path with a condition which is true. So while in practice we would expect the conditions to be mutually exclusive, in theory it could happen that two of them are true at the same time. However, XOR sends a token to a first path which has a true condition, so only one of the paths can be selected.
For OR gateway situation is different. Conditions of all paths are checked and each path which has a true condition gets a token. That’s why we will normally use a pair of OR gateways – for splitting and merging – just like for AND gateways.
Please take a look at the image below and compare differences between XOR and OR gateways.
How would your process log look like if we would have a hot (but not sunny) weather? For both types of gateways the result would be the same: ABEF.
To make it easier to remember let’s assume that it is a process of preparations for a walk and that task B is “Take a bottle of water”.
What about sunny, but not hot weather? Again, both are identical and we get ACEF. Task C could be “Take a sunscreen”.
And weather neither hot nor sunny will give us ADEF in both options. Task D could be “Take a hoodie”.
All those examples have only one token in a process instance, so we do not need any synchronization.
But if our weather is hot and sunny at the same time we will have a different situation.
Our XOR gateway cannot handle it well and (assuming the top path is checked first) we will have ABEF, so the same option as for the hot, but not sunny days. In other words, we will take a bottle of water, but not a sunscreen. Ouch! We might get a sunburn.
Luckily OR gateway comes to the rescue, and we will have ABCEF, which means we will not leave home without a bottle of water and sunscreen. Therefore we will be safe both from sunburn and dehydration 😉
Now, let’s see how do AND and OR gateways compare. As we already discussed, OR gateways allow you to duplicate tokens, just like AND gateways. However, they allow you to send tokens only to selected paths and have a smarter synchronization.
Why smarter? Merging AND gateway waits for tokens from all incoming flows, while merging OR knows which paths were active. So we can easily leave home without hoodie if it is hot 🙂
Last interesting feature of OR gateways which is similar to AND gateways is that you can have paths without a condition. Since they are always valid, they will also always get a token.
Please take a look at the animation below (taken from my course):
If you are worried that readers of your diagrams may not know it, you can always call those paths “always” 🙂
On the other hand – if you are feeling geeky and names of paths like “Neither hot nor sunny” don’t sound technical enough for something which basically reminds you ELSE clause from programming you can mark such path as a “Default Sequence Flow”. It will get a nice slash at the beginning.
Please note that “default” does not mean it is most probable, expected, most profitable etc. path. It only means that token will take this path if no other path has a valid condition.
I hope you enjoyed this quick overview of most common gateways in BPMN. Stay tuned for a new post – this time about Tasks.
PS. If you are curious – there are more gateways in BPMN, but the ones we covered so far should be sufficient for the most of you.
This is a third part of the series about tokens in BPMN. The first part was about basics and simple flow, the second one was about exclusive gateways (XOR). This time we will cover cases when our process has parallel paths.
Parallel gateways (commonly named AND) allow you to show that there are certain things in your process that need to happen, but they do not need to be performed sequentially. Like every gateway, it has a diamond shape, but with a + marker inside.
They can be performed at the same time e.g. by different people or some skilled multitasker 😉 but this is not required.
Important thing is that Parallel gateway will “copy” an incoming token, so that every outgoing Sequence Flow gets one. Those tokens flow independently through your process, so usually we need a second Parallel gateway to combine them again into a single token. This is called synchronization.
Why do we need synchronizations? There are several reasons. Technical reason: if you do not synchronize tokens, they will continue flowing and activating subsequent Activities. Business reason: usually we need AND gateways to show that some things need to be done before something else can happen.
Let’s imagine a simple process of preparing a report. After an initial analysis of a request we need some input from 3 teams: finance, marketing, and sales. It does not matter who sends us input first: finance, marketing, or sales. We need them all. After we have those 3 elements we can prepare a final report and send it.
Does it make sense to make a report on a basis of data from sales only? Probably not. Would the recipients be happy if we would be sending them 3 separate reports instead of one consolidated document? Unlikely. That’s why in 99% of cases AND gateways are used in pairs: one for splitting and one for synchronizing paths.
In case you are wondering what happens in this 1% when there is no synchronizing AND gateway: tokens flow independently, possibly causing some tasks to happen few times (so in an example above we could have a log ABEFCEFDEF). Only after the last token reaches end event process instance ends (unless you use terminate end event of course).
Since every path will get a token (we do not check conditions as we did in XOR) usually it does not make sense to add names to AND gateways.
Now, you may be wondering – would it be possible to have some paths which always happen and others which happen when certain conditions are true? Spoiler alert: you can do it with Inclusive gateways (OR), which we will cover in part 4.
Just like in the past years I prepared for you list of online courses (and other materials) which can help you learn more about BPM.
There are many courses about BPM, but those 2 really rock 🙂
Since some time 2 MOOCs by professors Marcello La Rosa, Marlon Dumas, Jan Mendling and Hajo A. Reijers are no longer available on Future Learn and QUT platforms, BUT:
a) You can access all the videos via Fundamentals of BPM website (there are also slides and other materials!):
(you need to look for part “Links to all video materials are available here (Copyright 2015-2017, Queensland University of Technology. All rights reserved).”).
b) You can also jump directly to YT playlists for those 2 courses
Introductory MOOC: https://www.youtube.com/playlist?list=PL9iw99lS3PrhyvCeigicFy0ncMOimILeX
c) Professor La Rosa kindly allowed me to present this content in a form more convenient for you.
Materials from a short introductory MOOC, “Business Process Management: An Introduction to Process Thinking“ (about 1,5 hours!) are available on a following pages:
Materials from the long MOOC “Fundamentals of BPM”
Part 1: Process identification and discovery
Part 2: Process analysis and redesign
Qualitative process analysis
Part 3: Process implementation and monitoring
Process-Aware Information Systems
Now, like in 2018 post I want to share with you also other courses (MOOC and others) organised by platform.
If you like to learn on the go you will appreciate nice mobile application Coursera offers. Most of the courses are by default paid ones (with access to all the content, possibility to check yourself and interact fully with others plus get a certificate), but you can always select the free path (called “Audit the course”) and access all the videos plus some of the course content. Courses on Coursera are MOOCs, so they have start and end dates, but you can switch sessions if you are falling behind (you may need it since they all start on the same date…).
Course description: “Today innovation is everyone’s business. Whether you are a manager in a global corporation, an entrepreneur starting up, in a government role, or a teacher in an elementary school, everyone is expected to get lean – to do better with less. And that is why we all need design thinking. At every level in every kind of organization, design thinking provides the tools you need to become an innovative thinker and uncover creative opportunities that are there – you’re just not seeing them yet.”

This is an e-learning platform offered by German Hasso Plattner Institute. It offers a mix of MOOC and on demand courses (i.e. archives of past editions). All courses are available for free. Mobile application is available.
As you can see from the URL this is a self-paced course based on a MOOC from 2016.
Course description: “This course introduces concepts of business process modeling using the Business Process Model and Notation (BPMN) industry standard. Participants will learn the elements of process models and their precise meaning. Based on a thorough understanding of business process models, the last part of the course covers decision models using the Decision Model and Notation (DMN). Decision models complement process models by representing concrete, operational decisions, both with their structure and their decision logics. The course centers around concepts and language to describe and analyze business processes and decisions. It does not cover methods on how to model, improve, monitor or implement business processes. Still, a deep understanding of business processes and decisions is a useful basis for these activities.”
Taught by: Prof. Dr. Mathias Weske
This is a more recent course 🙂
Course description: “Business process models play a central role in analyzing, simulating, and executing business processes. They serve as a communication vehicle for professionals with different background and expertise, ranging from business administration, quality management, and organizational development to systems architectures, and software development.
This online course introduces concepts of business process modeling and decision modeling using the industry standards Business Process Model and Notation, BPMN, and Decision Model and Notation, DMN. The course also covers concepts to describe and analyze business processes and decisions, and to simulate and execute them using modern BPM tools.”

Since last post some things changed, so I prepared an update for you 🙂
As in the last edition it is clearly visible that cloud tools are very popular. However it is still possible to find standalone BPMN modelers – pretty commonly they are offered by vendors of the process automation/workflow software. Please note that while some tools mentioned below are simple diagramming tools, others are more advanced and allow you to do much more than create BPMN diagrams.
So, let’s see what are the options:
Since several years ADONIS:CE is available for free in a cloud. Apart from BPMN diagrams you can also create process architectures, organigrams and make a comprehensive documentation containing not only interlinked processes forming a process architecture but also references to roles (using RACI approach), applications, documents, KPIs, risks and much more. Recently also free mobile application Ask ADONIS was added.
Academic edition is also available with DMN, simulation and teaching materials.
Bizagi offers unique approach to process modelling. It is a standalone (Windows) application, but also cloud “Modeler Services” are available in a freemium model. Free tier gives you unlimited models and diagrams and 10 MB of storage, while paid plans allow you to simulate processes, create process architecture, collaborate with others etc.
Since Bizagi is a process automation company it should not be a big surprise that you can use Bizagi Modeler to prepare automations. You start by modelling your processes in Bizagi Modeler, extend it with forms etc. in Bizagi Studio and finally automate it with Bizagi Automation.
This list would not be complete without BPMN.io and its siblings created by Camunda 🙂 They share many characteristics (as you will immediately see) such as possibility to create BPMN, DMN and CMMN diagrams, but have important differences.
BPMN.io is web-based modelling tool. You can use it without any registration, so I am often showing it to my students so that they can see how easily they can move BPMN diagrams between various tools (in my case I show how diagram created in BPMN.io can be saved as XML file and imported into ADONIS and vice versa).
This is a standalone tool which can be useful if you want to create BPMN/DMN/CMMN diagrams with no access to the internet or if you want to prepare your processes for automation on Camunda platform.
As the name suggests (CAmunda WEb MOdeller) this is a web modeller too. However while BPMN.io allows you to work on a single diagram and export it without storing anything permanently, Cawemo allows you to store your diagrams in a cloud repository, share them and collaborate with others.
This is not a totally new tool – just a rebranding of BeePMN which you may remember from 2018 edition of this post. It is also present in BPMN MIWG demos since several years.
Free version of Cardanit allows you to create 5 BPMN and DMN diagrams with up to 30 elements, so this is a good option if you are just starting and do not need a big process architecture.
Apart from the tools described above there are also many other interesting tools. Below you can find an overview of the selected ones.
If you are using other free tools which support BPMN let me know in comments!
If you like to model your processes using EPC this is an interesting choice. Apart from EPC, it also allows you to create BPMN diagrams, Process landscapes, organizational charts, data models, IT infrastructure diagrams and more! This is a standalone (Java-based) application, so you do not need internet access to use it. Unlike professional version of ARIS, ARIS Express stores all your diagrams as files, so there are very limited options of creating more complex process documentation with connections between various layers of organization. Last update of ARIS Express was in 2017.
Browser based diagramming tool. It allows you to create many diagram types – including BPMN, but does not allow BPMN Diagram Interchange (it only has proprietary XML).
As you may recall from the earlier posts about BPMN Model Interchange Working Group live interoperability demonstrations we usually had part of modelling and exchanging BPMN diagrams among participating tools and at the end session where automation was shown. In 2018 and 2019 we did not have time to show the automation.
In 2020 edition of our demo automation is back 🙂 As previously this presentation will be part of Object Management Group technical meeting (during BPMN in action slot).
As you may guess this event does not take place in Orlando as it was planned, but is virtual so you can easily join us live by registering on OMG website for the event (or using direct link to GoToWebinar registration page). It takes place on Monday June 22nd 11.00 am – 12.30 pm ET.
For the first time we will be streaming the event using GoToWebinar and not Hangouts/YouTube, so keep your fingers crossed!
This year we will have 11 participating vendors: BOC Group, Camunda, Cardanit, Case Agile, Itesoft, KnowProcess, OMNITRACKER, Signavio, Software AG, Trisotech, and Viadee. 6 vendors (BOC Group, Camunda, KnowProcess, OMNITRACKER, Signavio, Trisotech) will be showing automation.
Our demo scenario will be based on a (fictive) EU Bank which documents the current state (AS-IS) processes and develops future state (TO-BE) for the recruitment. If you are using ADONIS probably you will recall those processes since they are (again 🙂 ) based on ADOmoney Bank example.
Here is the overview process architecture which was not part of the interchange demo as it is not BPMN 😉
The recording is now available on YouTube, so you can watch all the session plus Q&A.
You can also download our diagrams from Github:
Below you can find few screenshots where Denis presents models used in the demo.
As you can see first model was extended a bit with Data Objects and object names were shortened (since during our demos it turned out that we don’t have time to type everything 😉
PS. To learn more about BPMN MIWG and watch recordings of past demonstrations visit our site: http://www.omgwiki.org/bpmn-miwg/doku.php
You will also find there test cases and list of tools participating in MIWG tests.
PPS. Below you can see major points of the webinar
Meg Duncan from OMG starts the session and tells few words about Object Management Group.
Denis Gagné starts presentation at 2:56. Denis mentions 11 participating vendors and BPMN 2.0 10th anniversary.
He continues by presenting idea of model interchange (also including hidden attributes).
Afterwards our scenario is presented: EU Bank 🙂 and you can see how it is split between various tools.
Please note that many things will be done in parallel since we had limited time for the demo.
Niall from Camunda starts modelling at 8:51 by creating diagram in Cawemo.
In parallel Gabriele from Cardanit starts modelling another process at 9:54.
At 10:55 Denis introduces Frank from Software AG (ARIS tool) who will start modelling third process.
At 12:05 we move to Simon from Trisotech who will be completing diagram from Niall
As Denis mentions BPMN provides a modelling standard, but each tool has own “tool smarts”.
Tim (KnowProcess) starts extending diagram from Gabriele at 13:55.
Since ARIS part is ready, now (14:54) Chris from viadee can continue.
At 16:05 you can see Benjamin from Itesoft who will extend Simon’s model.
Now at 17:20 Philipp from Signavio continues Tim’s work.
Marion from Omnitracker joins at 18:36. You can also hear Denis explaining that BPMN does not specify colors, but some tools support “BPMN in color” extension.
At 20:20 Benjamin is done and shows the first process: Recruitment (AS-IS).
At 21:20 Boris (CaseAgile with Enterprise Composer) joins the group to extend model from Cardanit in his Visio add-on.
Zbigniew from BOC Group (yes, it’s me) with ADONIS joins at 22:15 to continue Marion’s model. Denis tells more about why BPMN MIWG is needed to make sure tool vendors reach a common understanding of the specification and how do we work together. He also provides a small teaser of the upcoming automation part.
You can see overview of the Online recruitment process at 25:10.
Denis invites viewers to ask question at the end of the session.
Boris shows his full model at 27:05.
And now we are ready for the automation part (27:43)!
I learned from Sandy Kemsley (read the original post on column2.com) that Springer is now offering many interesting books and journals for free.
So, if you watched the Fundamentals of BPM MOOC videos and want to deepen your knowledge this is a great opportunity to read the Fundamentals of Business Process Management (2nd edition)!
January is often time when we come up with resolutions for a new year. While it is easy to decide that we want to change something, change will not happen unless we start doing something differently.
That’s why, like in the past years, I prepared for you post with suggestion regarding skills which will be useful for process professionals.
Every year is a chance to learn (and use in practice) something new. I believe in learning from the best – this is why on this blog you can find world-class BPM experts sharing their knowledge with you 🙂
I think that one of the best sources of knowledge about Business Process Management is the “Fundamentals of BPM” book along with the MOOC courses based on it.
You may recall from my post “Back to school 2019: free online courses for BPM professionals” that while awesome MOOC course “Fundamentals of BPM” (run till 2017 by QUT) is not available anymore in an interactive form, video recordings are available.
Professor Marcello La Rosa kindly allowed me to present them in a form more convenient than the original PDF (available on http://fundamentals-of-bpm.org/mooc/).
Below you can find links to pages with videos.
