    • Thursday, October 27, 11
    • Agenda • Introduction, why BPM? • Business Processes • BPM the discipline -> Main Stages • BPM Systems • jBPM5 Components • Process Runtime (BPMN2 models) • Human Task Server (WS-HT Spec) • Tooling • Service Repository • F.A.Q.Thursday, October 27, 11
    • What does Process mean for us? Set of ordered actions that tends to transform an input to a desired outputThursday, October 27, 11
    • What does Business mean for us? Relative to a domain, company or a scoped scenario, where certain rules and actions needs to be applied to achieve a goal.Thursday, October 27, 11
    • What does Business Goal mean for us? Objective to be satisfied inside the business scope that gives to the company a profit/benefit in some way.Thursday, October 27, 11
    • Business Process Sequence of actions performed by humans and systems to achieve a business goalThursday, October 27, 11
    • Business Process ExampleThursday, October 27, 11
    • Business Process Management • Obviously when we have more than 2 Business Processes we need to manage them! • History • Main StagesThursday, October 27, 11
    • Business Process Management History • Was born more than 30 years ago • Focused on improve how companies work • Workflows, person to person interactions come first •A business related approach come later with high level concepts • The BPM discipline was created to provide a framework where business processes can be discovered and improved over the yearsThursday, October 27, 11
    • Business Process Management Stages • Stage #1: Discover (Quality) • Stage #2: Formalize (Quality) • Stage #3: Implement (Technical) -> Devs!!! • Stage #4: Runtime (Technical) -> Devs!!! • Stage #5: Monitor (Decision Making) • Stage #6: Improve (Quality)Thursday, October 27, 11
    • BPM CycleThursday, October 27, 11
    • BPM Systems • You can do the whole process with a pen and paper • Or you can use a Business Process Management System • It gives you a set of tools to implement each stage • Developers needs to understand the key features of a Process Engine • Developers needs to understand the tooling that the BPMS provides themThursday, October 27, 11
    • jBPM5 Quick Overview • Its a Business Process Management System • It provides us the process engine • It allows us to model our process using BPMN2Thursday, October 27, 11
    • jBPM5 Quick Overview • It can be easily embedded in your applications or used as a service • It will be responsible to handle the interaction between Human and Systems defined inside our business processes • Focus: reduce the gap between developers and business analyst to model and execute business scenariosThursday, October 27, 11
    • jBPM5 Components Overview • jBPM5 Ecosystem • jBPM5 Runtime • BPMN2 Semantic Module • Core Business Process Engine • Persistence and Transaction Mechanism • History Logs • jBPM5 Human Task Server • jBPM5 Service Repository • jBPM5 Tooling • jBPM5 Designer • jBPM5 Process Console • jBPM5 REST Process Server • jBPM5 BAMThursday, October 27, 11
    • jBPM5 Core Overview (Process Perspective)Thursday, October 27, 11
    • Drools + jBPM5 OverviewThursday, October 27, 11
    • jBPM5 Runtime • BPMN2 Semantic Module: it understands BPMN2 process definitions and lets us load our process definitions into the jBPM5 Runtime. • Core Business Process Engine: it runs our Process Definitions. It provides a full set of APIs to interact and create our process instances. • Persistence and Transaction Mechanism: it helps us to store the runtime status of our running processes • History Logs: it stores all the activity that its being executed in the engine.Thursday, October 27, 11
    • BPMN V2.0 Introduction • Business Process Model and Notation V2 • Standard Specification created by the Object Management Group (OMG) • Publicly released: 2011-01-03 • Define best practices for Business Process Model definitions and Business Process implementations based on industry expertiseThursday, October 27, 11
    • BPMN V2.0 Goals • Defines a standard language to model business process that can be understood by: • Business Analysts • Technical IT people • Business People • Defines the execution semantics for that notationThursday, October 27, 11
    • BPMN V2.0 Goals • The specification its divided into three main sections • Process: • Process Modeling • Process Execution • Collaboration • ChoreographyThursday, October 27, 11
    • jBPM5 Human Task OverviewThursday, October 27, 11
    • jBPM5 Human Task Server • Pluggeable component to handle the human tasks life cycle • Implements the Web Service Human Task specification -> http://incubator.apache.org/hise/WS-HumanTask_v1.pdf • It defines the data structures to store information about the Human Tasks involved in our processes, without knowing about the process itself • It defines the different states that a human task can have during the interactionThursday, October 27, 11
    • jBPM5 Tooling OverviewThursday, October 27, 11
    • jBPM5 Tooling • jBPM5 Designer: Graphical Process Designer that lets us define BPMN2 compliant business processes. • jBPM5 Process Console: It lets us test and run our processes, providing us a runtime environment where we can interact with them.Thursday, October 27, 11
    • jBPM5 Tooling • jBPM5 REST Process Server: It exposes the jBPM5 runtime through a REST interface to be able to interact with the runtime from different clients and programming languages. • jBPM5 BAM: It provides us some widgets and reporting features to externalize, browse and aggregate information that its being generated from the processes execution.Thursday, October 27, 11
    • jBPM5 Human Task Server • Connectors for including domain specific activities • Centralize in a repository the already created connectors • Promotes reutilization • Allows us to have a private repository with our private domain specific connectorsThursday, October 27, 11
    • jBPM5 Source Code jBPM5 Source Code http://www.github.com/ droolsjbpm/jbpm Get the code and build it! > git clone https://github.com/.. > mvn clean installThursday, October 27, 11
    • How BPM fits for everyone • Business processes represent • The steps required to do a specific work • Great for End Users, New End Users and Managers • How to coordinate systems (Systems Integration) and human interactions • Great for developers and re-utilization • End Users will end up with an Unified User Interface • Developers will have an unified way of doing new developments/adding functionalityThursday, October 27, 11
    • How BPM fits for everyoneThursday, October 27, 11
    • How BPM fits for End Users • Task Lists Oriented User Interfaces • Its easy to know what tasks have each role inside the company • Just one way of doing things, unified, in the same place • The task lists guide you through your tasksThursday, October 27, 11
    • How BPM fits for End Users (Task List)Thursday, October 27, 11
    • How BPM fits for End Users (Task Form)Thursday, October 27, 11
    • How BPM fits for Developers • Easy to maintain • Decoupled from the application code • Encourage re-utilization of the communication mechanisms and connectors • Changes in the business processes dont affect the application neither the UIThursday, October 27, 11
    • How BPM fits for DevelopersThursday, October 27, 11
    • How BPM fits for Developers • Developers will be in charge of: • Create connectors for different applications (or use the ESB and configure each new system) • Store the connectors in a centralized repository • Define the technical aspects for each task type interface • Configure the environment to run the business processes • Maintain the business process definition technical assetsThursday, October 27, 11
