  • Basically, all business processes can be modeled, but not all processes has IT support. Of the IT supported processes – e.g. abatch process, an online set of transactions – some are workflow based. Those are the ones of interest here
  • Different workflow systems focus on different aspects – some of these aspects are listed here. When selecting a workflow system, care must be taken to evaluate the business needs and workflow system capability. BPEL based workflow engines tend to balance these aspects
  • IBM reference architecture defines the relationship between major components and how they interact thru a Service Oriented Architecture with an Enterprice Service Bus as the transport layer.
  • The first point to make is that the key focus is on ease of use – we want the business analysts who know the business to be able to do the modeling without them needing to have an in-depth awareness of something like BPEL. We have the ability to model a lot of detail, however the tool allows you to model at just the right level of detail you need to model Collaborative modeling allows for the modeler to communicate their designs with the wider enterprise and allow their participation in the modeling exercise via feedback mechanisms. Another usage pattern of the Collaboration support is for training of users – the To-Be process can be communicated with a wider audience to help them understand the changes made and how that impacts them in their interaction with the process. The model can then be transformed and exported for consumption within the IT tools – principally WebSphere Integration Developer v6.0. The Integration Architect/Specialist will then add further levels of IT detail to the model to prepare it for deployment to the runtime environment.
  • The key point to take away from this slide is that there are multiple facets required to provide business understanding and WebSphere Business Modeler addresses this by providing multiple complementary models.
  • A typical BPM project requires integration with many key components
  • Business subject matter experts are involved in defining the AS-IS and TO-BE processes. Technical ressources skilled in the services being invoked add specific technical information (e.g. which CICS trancode to invoke, parameter setup). Also, the WPC modeling is done by technical people skilled in WPC and Java (some java knowledge required). Typically, the business people model at a somewhat higher level using Powerpoint, Visio or WBI Modeler.
  • This is an example of a menu based case processing application. Notice that the sequence of activities is not the same as the listing of the menu items – experienced users have learned which sequence, activities must be performed in. Also notice on the animation that step E is not executed for this particular case.
  • The drawbacks of menu based processsing are listed here. The process state is in the head of the user and the state is not well defined if the user freely choose the sequence of activities. If the state is not well defined, it is hard or impossible to let other users do some of the activities – they dont know what has been done. Therefore, the same user runs the whole case. The users must learn the sequence of steps and the condition for executing each one and they must know the business rules – hence users must be told when a rule changes. If something goes wrong e.g. if an inexperienced user does activities out of sequence, the user has to correct the mistake. Finally, automation is rarely done, because automation requires context and rules as seen from the next slide
  • This slide illustrates several points: First, with the state and sequence of activities build into the flow, different users can be requested to do different activities – specialization that will free up skilled ressources and let lesser experienced people do the simple tasks. That does not prevent freedom of choice of sequence for the users – where it makes sense.
  • Secondly, workflow leads to automation of low risk activities freeing up ressources – often in the range 25%-40%. Activity E could be an approval of a low risk situation where the amount is low. Also, by changing the business rule from amount>100000 to >200000 further optimization can be done, and the users dont have to be instructed in this changed rule, reducing learning time and errors. Errors are reduced by allowing only valid sequence of activities and error handling can also be automated for different error types.

    • Open Common Standards
    • Tools
    • Models
    Models, Execution Engine, Monitor
  • Business Process Management and Workflow
    • The term Business Process Management refers to activities performed by businesses to optimize and adapt their processes .
    • Although it can be said that organizations have always been using BPM , a new impetus based on the advent of software tools which allow for
      • direct execution of the business processes without a costly and time intensive development of the required software.
      • In addition, these tools can also monitor the execution of the business processes, providing managers of an organization with the means to analyze their performance and make changes to the original processes in real-time
    • BPM has a tight link to componentized and service oriented IT architecture
  • BPM landscape - Workflow Classification User Experience Document Centric WF systems Collaboration Based WF systems Business Process Manager (BPEL Engine) Department or single user WF systems Collaboration Documents and forms Processing Data and Function Integration
  • Workflow – what is it ? Service X Service U Service Y Service Z Workflow Workflows implement business processes Workflow engine navigates the network of activities Typically invoking automatic (service choreography) or manual activities Mostly visual programming/modeling Human Task A Human Task D Human Task F Human Task B Human Task C Invoke Invoke Invoke Invoke
  • Cost Benefit Benefit sample: Pilot project: 1 hour saved/process instance, 400 instances pr day 400 H/day = 60 FTE Implementing an enterprice wide BPM Infrastructure is a major strategic investment.
  • Business benefits from the Process Oriented Approach
    • Process modeling - a new approach to application and service development – a radical change from traditional application development
    • Key benefits :
      • Visibility & commonality of processes
      • Processes as the common ”language” between IT and business
      • Cost reduction through flexible automation – typically 20+%
      • Process optimization and streamlining across applications and the enterprise
      • Continuous, nondisruptive process improvement
      • Monitoring provides understanding of WHERE the employees spend their time
        • Base for new automation
      • Faster implementation of changes in processes – typically 30+%
      • Optimizing skills usage in the business
      • Excellent match & synergy with SOA/ESB
      • BUT : Users think in ”Cases” – same person for the whole case – takes time to start thinking in processes / activities ”best man for the job”
  • Modeling for Different Goals
    • Modeling For Compliance/Documentation
      • Document processes for use by a business to understand the business process
      • Customers use output for training, collaboration, documentation requirements for compliance regulations ( Sarbanes-Oxley and Basel II )
      • Linkage to real-time monitoring provides a feedback mechanism for reporting requirements needed for compliance
    • Modeling For Redesign
      • Document both the current state and future state business process and the comparison to determine Return on Investment (ROI) analysis
      • Six Sigma and process improvement are common methodologies
    • Modeling For Execution
      • Future state business process has runtime characteristics associated to it, so the model is passed to application, workflow and business process development tools.

    • Process state is in the head of the user
    • Usually same user for all activities (inflexible)
    • No specialization (”Do what you do best”)
    • User must understand process (skills)
    • Business rules in the head of the user (skills)
    • Business rules harder to change (efficiency)
    • Error handling is left to the user (skills)
    • Automation usually not done (requires context)

    • Not one size fits all
    • Local model extensions provide agile, customized ”best practice”
    Example: Validation Eclipse plug-in flags violation to customer standards
  • Summary
    • Business Process Management provides huge potential for savings
    • SOA naturally leads to a BPM Approach
    • Open Standards is the base for future development
    • Models are everywhere – and converging towards common models, e.g:
      • Component Business Model
      • Business Modeler high level models (XMI) for
        • Visualization
        • Simulation
        • Documentation, agreement
      • Business Measures Models + (organization, strategy, goal,...models)
      • Business Process Models for execution (BPEL + IBM extensions)
    • Always a need to add model extensions to standards
      • IBM extensions and customer extensions
      • ” Fill the gap” models
      • Validation of ”Best Practice” tools
      • Way to keep the BPM software agile
  • Closing
    • Quote:
    • ” Vision without Action – is just day dreaming.
    • Action without Vision – is just passing time.
    • Vision with Action can change the world” (Joel Barker)
    • Models without execution – is interesting...but
    • Combining modeling and execution capabilities brings us to a new level of application development and automation
