Not particularly worried about the commercial side of things, it is just the Open Source issues that concern me. Open Source facilitates much research, and if Worlds.com decide to try and monopolise the area, then researchers like me and my kith and kin are in trouble, as they can dictate very restrictive terms on the use of software.
I will be following this one very closely indeed.

OII SDP 2009: Brisbane (6-17 July, 2009) http://www.oii.ox.ac.uk/teaching/sdp/
The programme aims to stretch the thinking of all students on a range of issues, to provide valuable advice and support for students' thesis research, and to establish a peer network of excellent young researchers. Perhaps unsurprisingly, the thematic focus this year will be on 'Creativity, Innovation and the Internet': our partners on the SDP since 2003, the Creative Industries Faculty is at the forefront of pioneering international research initiatives in creative industries policy, applied creative industries research, digital media design, and the creative and performing arts.
As in previous years, the programme will involve daily research seminars and panel sessions given by leading academics, with students having the opportunity to present their research to their peers in informal seminars. Break-out sessions will allow groups to focus more narrowly on research questions of mutual interest, and time is made available for individual research and informal contact with tutors and fellow students.
Student feedback on the Summer Doctoral has always been overwhelmingly positive, and the SDP 2009 promises to be yet another excellent year in this series. I hope you will consider applying, encourage your students to apply, or forward this email to people who may be interested! Please don't hesitate to contact me if you have any queries.

Explore new applications, business ideas and research challenges
at the intersection of things and services
Colocated with the UIC-09 Conference on Ubiquitous Intelligence and Computing
Brisbane,Australia, 7-10 July, 2009

* AIM & SCOPE
Services are the dominant type of economic activity in industrialized economies. The term Internet of Services relates to the representation and (partial) execution of services - in the
economic sense - in the Internet. Many issues around the mapping between economic services
and services in the IT sense are still unresolved. Additionally, only a small fraction of services
are entirely dematerialized; the vast majority of services ultimately relate to things in the real
world: to the Internet of Things. The Ubiquitous Computing community has already made
considerable advances in closing the information gap between services and things. One well-known example is the use of RFID tags in logistics. Yet this is only the beginning, there still
exists a largely untapped source of innovation at the junction of services and things.
ubiquitous computing techniques can help improve existing economic services and create
opportunities for new services. We are also interested in how services can add value to smart
things. This is a forum for industry to learn about recent advances in both services and
Ubicomp and also for researchers to learn about the problems faced by industry that may
spark new research questions and the next wave of Ubicomp applications. We solicit a) technical papers with a proven original scientific contribution and b) systematic, well-founded experience reports and requirements / demands analyses. Core IT papers and papers at the boundary of technology and business or humanities are also invited.
We also welcome contributions that address solely the topic of services, independently of
ubiquitous computing, since we believe this also contributes to cross-fertilization of ideas in
the context of UIC-09. Technical, business and legal aspects of services all have their place
- Identification of services in existing systems and business processes
_ Approaches for fostering the creation, use and re-use of services
- Aggregation, brokerage and re-purposing of services
- Personalisation of services to classes of users and individual users
- Channels and technologies for accessing services
- Service lifecycle management
- Legal aspects of service ecosystems
- New business models enabled by smart things
- Doing business better, cheaper, faster, greener with smart things
- Economics and sustainability of using smart things
- Applications of things and services in media and advertisement
- Applications of things and services to delivering healthcare and services to citizens
- Applications of things and services to manufacturing and supply chain management
- Lifecycle management of smart things
- Discovering services through smart things
- Discovering smart things using services
- Machine-process able representations of services stored in smart things
- Linking smart things to their related services
- Representation of real world things in virtual worlds
- Running services inside smart things
- Privacy and security issues with things and services
* SUBMISSION & DISSEMINATION
We invite all researchers to participate by submitting an original paper of up to 6 pages in IEEE
CS style. Please see the workshop website for document templates and for details on the
submission procedure. Each paper will be reviewed by at least two members of the PC.
Accepted papers will be published by the IEEE in a single volume with proceedings from all UIC-
09 workshops. Extended versions of the best papers may be invited for publication in a journal
at a later stage.

- Particles at this scale naturally clump together highlighting the major areas of air travel.
- Integration with a world daylight representation provides a suitably visually orthogonal set of representations for easy spatial comparison of time of day and air travel intensity.
- Air travel is seen as an aggregated daily process across the world.
- Aesthetically it is pleasing - ugly visualisations are beyond contempt.
- It also brings home - if air travel is postively correlated with economic activity - why the US still strongly influences the world economy.

My assessment in short, is that Exit Reality requires a lot more work to make it usable and attractive as an environment for socialising. It is trying to attempt something very difficult, the integration of web multimedia information and 3D interfaces. They should be congratulated on the attempt, but it just doesn't work for me.
Here are some reasons:
- Exit Reality is slow and buggy. Games and virtual environments require smooth reliable interfaces to make the paradigm work properly, especially as such bugs disrupt the immersive experience. The games industry understands this, that is why they all have such large QA sections. Exit Reality needs to invest in some more bug testing.
- The way they handle general web pages is problematic. My University home page came up as a sea of small signs that conceal each other, making it more difficult to traverse the website, thus undermining any benefit that 3D VEs can bring to web pages. I would have thought that some nice cone trees or hyperbolic views may have been better. Not sure they did much of a usability analysis before developing this general web component.
- Apartment style metaphors for socialising, while engaging in their novelty, are not that usable. It takes a number of seconds to traverse the space in 3D, that would otherwise require a couple of mouse clicks in a 2D page.
While I applaud an Australian company for sticking its neck out on a difficult technology, I am unfortunately critical of its present ability to be more useful than the present 2D social networking forms. I think they have to go back to the drawing board to rethink the idea.

Apparently I am the creator of YAWL now...not sure Arthur ter Hofstede will be that impressed.

One criticism of using 3D environments in the first person, is the difficulty of navigating them correctly - slapping such textures over your visualisations might just do the trick.
Tuesday, July 29, 2008
Possibly suggesting more scope for serious use of the technology, than other fields.
I would argue that this is due to the configurability of SL, and its ability to garner information from other sources on the internet, and produce visualisations as such in situ, as we have shown with business processes at QUT.
BTW, the graph is a nice intuitive visualisation of Age Demographic with Age of World using a Polar Coordinate approach.

I have embedded a video from Youtube of the system in action, titled Clik Goes to Hollywood. What we have done in effect is to facilitate the 3D collaborative visualisation of dynamic business process models. The visualisation has been developed from the 2D YAWL control flow model illustrated at the top of this post, into a 3D animation in Second Life, embedded below as a video. The process model illustrated is drawn from the YAWL4Film project being undertaken by the BPM Research Group at QUT. Clik, the avatar in the animation, is not controlled by a human, but is controlled by the YAWL workflow engine.
More will be revealed as I duly publish some papers...

- What does this do to your perception of an information system?
- Does it make it seem more immediate? - as its controls are mapped to intuitive, spatial and temporal artefacts for you to manipulate.
- Do you have a greater/lesser sense of control?
- Does it change your understanding of what the process model is doing?
Saturday, July 5, 2008
Such visualisations make it a lot easier to understand the Dynamics of the service being investigated. Much easier, as I have said many times before, than using static diagrams to simulate business processes. Plus the collaborative nature of Second Life facilitates interactions with fellow stakeholders in the business.
Stay tuned, QUT will have its own offering in this area soon.

What is interesting is the derivation of Process Sponsor and Operational Manager roles within an organisation. In particular, the article shows some derivations of finer grained tasks that are performed by such people. Most Visualisation approaches for BPM are restricted to just roles, which is fine. However, I argue that a visualisation is meant for a task, because it is about providing information for decision making. Since a process manager or sponsor has many tasks to perform, each visualisation, I argue, needs to be tuned to help them make decisions for that task.
Treinish published an interesting paper on this issue a while back, but the truth still holds. As we often produce differing text for differing tasks, so too we should modify visualisations to fit a task, not just a role in an organisation. Case in (simple) point; if I was a modeller talking to another modeller, then I would use a BPMN diagram, due to the compact, iconic representation being easy for experts to use. However, if I was a modeller explaining a process system to a naive viewer, I would not use BPMN, I would probably use a full 3D simulation to get my point across. In fact, the later is often done regarding community consultation in Urban Planning applications, CAD drawings just don't cut it when talking to investors and residents about how a site is to be redeveloped.
I believe this holds across the board, for executable and non-executable modelling systems.

Study of Visual Layout on Understandability of Process Models
I would like to encourage you to participate in an online experiment which is part of a research project conducted by the Eindhoven University of Technology by Maria, a student of Hajo Reijers.
The objective of the research is to develop some guidelines on how to draw process models in order to improve their visual quality and, therefore, their understandability. The experiment will take you around
Your participation is anonymous.
We will appreciate very much your collaboration!

This is a teaser for some of the work we are performing at QUT to integrate Second Life with other software. The avatars are controlled by web services, and deliver the lecture themselves.
I've had this paper and demo floating around for a while now, and have just got around to posting it. This is a video of some work a student of mine performed linking a game mod to the YAWL workflow engine developed by QUT.
The grey user interface, spawning of enemies and registration of killings is coordinated by the YAWL workflow tool, developed at QUT, Brisbane, Australia - http://www.yawlfoundation.org/
This shows how easy it is to give a 3D interface to workflow systems, and shows a very simple example of how to control the "Narrative" of a virtual environment by using workflow systems. In the end, a game quest is just a form of goal directed workflow, so I decided to test it out, and the video is the result.

Just watched this video from a colleague at work. It is an example of "Target Focus" - the exclusion of other information when performing certain tasks. This can be a problem if you are a dive bomber, as you may not pull up in time due to this focus of concentration. :-)
What has this to do with BPM Visualisation? Well, usually you only really need to present the information required for a particular task when viewing a process model, as the other information is either ignored, or becomes a hinderance to the task. The human visual attention system accomplishes this quite well, as you discover in the video. The question is, can we develop good psychological models to filter useless information for task-oriented visualisations. My impression is (at the moment) that at this moment in time the process visualisation community is lagging behind the other visualisation researchers and practitioners in using this approach.
As a counter argument, the removal of too much information may hinder the process analysis task at hand just as badly. So effective task-oriented process perception models may be a good research area to develop, to fine tune visualisations to a deeper task oriented level, past higher level role oriented information filtering that is presently proposed.
What do you think?

However, what is peeving me is the representation of the power plants by the media, even good old Aunty herself, the ABC. Every time they take a camera shot over a power plant (VOD Cast for 21st March 2008), they focus on the large concrete towers that emit steam, not CO2. The towers are a part of the water reclamation process. They conveniently emit lots of billowing clouds of water condensate that looks like smoke, and so are a lightning rod for emotive media representation of the power generation process.
It's probably just an honest mistake, as the camera views of the billowing towers are impressive, but it shows that such misinformation via visual misrepresentation can give you a completely inaccurate view of a process. In effect, they chose the wrong icon to represent the activity, and now some people are going to have the wrong idea about the process of electricity generation.
BTW, the dangerous stuff comes out of the skinny chimneys nearby. :-)

However, I can't help but wonder if the issue here is to do with the visual nature of the diagrams, and their interaction capabilities. Most software I know of that uses this standard presents the diagrams in an inanimate, low-level interactive manner. While this works well for certain stakeholders in a process modelling scenario, it does not bode well for those that think in a different manner, especially if they are new to the field. For instance, you model the business, and then show the user the model and expect them to understand easily. I think a static diagram does not work here for people who are not BPMN experts.
Would more components be used if it was clearer what these icons meant, and what they model? Most of the time we avoid software functionality as it is too hard to find out its usage. And no, RTFM just doesn't cut it as a methodology, because we usually learn by doing, and the doing requires tools that clearly show their functionality.
I think a lot of pedagogical theory could be applied here to look at how animation could be used to show the functionality of the diagram. Not in a simulation manner, but simply in a base functionality level. The user could use a tool to brush over the diagram to generate animations that indicate node or group levels of functionality.
For instance, as an icon is inserted into a diagram (xor-split say), it could animate itself judiciously to indicate that one or the other choice in the branch is made, and not both.
This technique has been applied in other visualisation fields, and I think it could work here.
Found this Youtube video on Infosthetics.com. Watching the "Dude" scatting cracked me up. Yes, it is stereotypical in nature (it is from 1971), but boy does it make a statement about the imagination levels of certain people...in that inimitable cute muppet way.
Have been following a conversation between Michael zur Muehlen and Bruce Silver on the usage of BPMN functionality. Can't help thinking that maybe there would be more uptake if the "Dude" designed the diagrams... ;-)

1st International Workshop on Governance of Service-oriented Systems(GovSOS'08)held in conjunction withIEEE Joint Conference on E-Commerce Technology (CEC'08) and Enterprise Computing, E-Commerce and E-Services (EEE'08)(CEC/EEE 2008)
Crystal City, Washington, D.C., USAJuly 21-24, 2008
Deadline for submissions: March 30th, 2008
The purpose of this workshop is to bring together researches fromacademia and industry, as well as practitioners interested in thedifferent aspects of service-oriented systems governance.We seek contributions from practitioners in industry and government,as well as from academic and industrial researchers. We especiallyinvite contributions from industrial partners that have a richexperience in the area of governance of service-oriented systems.
The central workshop theme is Governance for Service-orientedSystems. Over the last years, the field of Service-oriented Computing(SoC) has emerged as a paradigm for managing the developmentcomplexity of large-scale (enterprise) systems and for creatingdynamic and autonomously adapting software. There are a number of openresearch issues in this area, with governance as being one of them.Governance of service-oriented systems is a very important conceptthat deals with all activities related to the control and managementof the services landscape within and across organizationalboundaries. In this workshop we would like to address governance ingeneral, in particular we focus on the following themes:* Service-Lifecycle Management:Service-lifecycle management deals with a magnitude of issues such asdeployment, assembling and testing of services. Service versioning isanother important issue that arises during the evolution of a service,thus requiring a dedicated versioning support from the SOA-basedinfrastructure. As composite services become more and more important,issues such as dynamically reconfiguring/rebinding a composition areincreasingly challenging. These issues all need a strong SOA runtimeand infrastructure support to manage SOA-based solutions in anonintrusive and non-disruptive manner.* Management of QoS and SLA:Quality of Service (QoS) and Service Level Agreements (SLA) are anintegral part of service-centric systems to express the qualityattributes provided by atomic services and service compositions. Suchquality attributes can be grouped in an agreement to specify anagreement between the service provider and the service consumer. Thespecification, management and enforcement of such agreements requirestrong support from the SOA infrastructure. The workshop shouldaddress these issues by discussing quality of service and SLA models,
issues related to monitoring of QoS attributes, agreements, automatedSLA negotiation, negation protocols, etc.* Compliance Management:Compliance to standards and laws (e.g., ITIL for service management orSarbanes-Oxley Act) is important for an enterprise to adhere tocertain required regulations and to demonstrate certain qualitycompliance to business partners. Work in this area should discussnovel approaches to monitor and manage the compliance (e.g., byapplying self-adaptive and policy based monitoring) that allowschanging compliance regulations without modifying the services itself.
Here is a (non-exhaustive) list of particular topics that addressdifferent aspect from above:* Service-Lifecycle Management* Service Versioning Approaches* Monitoring Approaches (Service, Processes, Infrastructure)* SLA Policy Specification and Enactment* Quality of Service Models* Autonomic Management of Service Level Agreements* Performance Management and Analysis* Infrastructure and Runtime Support for SOA Governance* Event-Driven Architectures for Governance* Service Modeling and Capacity Planning* Managing Service CompositionsWe seek papers that address these aforementioned issues by discussingnovel ideas and provide detailed insights into their softwarearchitecture that implements their proposed approaches. Contributionsin all other areas related to SOA governance (and not listed above)are more than welcome.

This is the issue of having technical diagrams on paper, they are a physical thing that is hard to maintain. But, they are easier to use than a notebook with the same data, as they do not require power, are not fragile (well paper does tear, but this doesn't mean that it reboots on you ;-)) and within reason can be carried anywhere that allows enough room to unfold the print.
However, just as we want paper free offices, we want to be able to remove paper in technical diagrams. Now that some flexible displays are coming, we won't need such laptop or PDA bound methods of working, and will be able to play with a piece of networked paper.
How would you interact with such a set of diagrams? What sort of tools would you need to manipulate such information on a paper-based display, that is automatically networked to headquarters. How do you play with such an interface with a number of people at once in an office?
Not only that, but what is the nature of a technical drawing when it goes live...
I think the time is nigh to stop thinking about technical diagrams in such a static manner, and begin to conceptualise the documents as living paper. Which makes me wonder why most diagrammatic representations of Business Processes are sooo dead in nature. They are simple 2D diagrams without many annotations to give extra information. In fact the information is the key (duh), so maybe it is the "display" technology that is the issue.
For instance, what about walking around with a HUD pair of glasses with annotations of your work place containing information about the processes in a spatial manner. Could be useful for process model verification and modelling for that manner.
Some work here to be done I think.

While these people talk about the need for greater integration of Business Intelligence into thses tools, to make it actionable, I wonder if people had a good visualisation of the concequences then it would make things easier.
People have not trusted computers with decisions due to a lack of understanding of what is actually happening internally when the computer comes out with a response to data.
I think a good visualisation (interactive in nature for prognosticating) would assist this process.

So once again, the Nu Zulunders have a jump in the area of computer graphics. Choice bro! :-)
It's a component of what I will be writing about here into the future, so no give aways at present, until I get some publications.
It seems that most analysis is at the level of "Geez, this is soooooo cool. I can see my processes as little men...", doesn't cut it in the usability analysis stakes.
I think it is relevant to spend time ascertaining whether the visualisations work for each stakeholder, and then maybe this can move from a geewhiz area to a rigorous professional contribution to the modelling of business processes.

Here is a link (via Boing Boing) to the exquisite drawings of a Clarence Larkin, Baptist minister and dispensationalist. He provided a number of charts to illustrate the "Process of Salvation."
Now why would I put this on the BPMVE blog?
I'm glad you asked. Visualisation has been around for thousands of years. From drawings depicting hunting grounds in caves to the present Second Life like environments, humans have been creating visual representations of processes to illustrate, educate and generally entertain.
The issues remain the same; the derivation of appropriate visual structures and styles to create an image to comunicate information relevant to a human task. Easier said than done - visualisation is thus an art and a science, with many failures.
Plus, I have a fascination for etchings. It is a fascinating art form, and reminiscent of the black line drawings we use on screens today for diagrams. While the images in the link are noisey in parts, the line art seems to do its job of communicating Xian concepts. Even in this time, layout, glyphs, metaphors etc. need to be designed to communicate effectively.
Anyway, somehow these old drawings tell me that I am researching a field that has been around for a long time. Which is kind of comforting.
