Business Process Management with João SilvaCERN Spring Campus 2014 University of Oviedo, Spain
Agenda • What is BPM? • BPMN • BPM at CERN • Activiti • Demo
Agenda • What is BPM? • BPMN • BPM at CERN • Activiti • Demo
What is a business process • Sequence of activities performed by one or more business participants in order to deliver value to the business • Can be represented as a workflow
Business Process Management • BPM is a means to study, identify, change, and monitor business processes • BPM is not about technology • BPM is not about creating diagrams • BPM is about improving business
Pin (chincheta) factory • Adam Smith’s pin factory buesiness process from the Wealth of Nations (1776)
Business Process Management • Management discipline • Software engineering
BPM as a Management Discipline • Analysing your business processes • Documenting your business processes • Optimising your business processes • Make the organization more efficient • The focus is on business processes
What do you need for BPMAAMD • Tools • Whiteboard • Word • Excel • Napkins! • Process modeling • BPMN
BPM as a Software Engineering Discipline • Tools to draw execution flows • Decorate diagrams with technical details • Run processes on a Business Process Management System
What do you need for BPMASE • Runtime engine (e.g. Activiti) • Executable process as input • Coordinates executions • Keeps track of state • State machine
Agenda • What is BPM? • BPMN • BPM at CERN • Activiti • Demo
What is BPMN • Business Process Model and Notation • Graphical representation of a business process • Current version is 2.0.2 (January 2014)
Why BPMN • Standardized • ISO standard in process modeling • Interchangeable • Capable of being interchanged between IT solutions (no vendor lock-in) • Executable • Automation improves process efficiency and consistency
Why BPMN (continuation) • Human-oriented • Contrast with BPEL, which is machine-oriented • Bridge for the gap between process design and process implementation
BPMN Example • Vacation Request Process
BPMN 2.0 Constructs • A set of elements plus rules used for representing a business process model • Events • Sequence flow • Gateways • Tasks • Sub-processes and activities • Transactions
Events • Model something that happens during the lifetime of a process • Visualized as a circle • Examples Start Event Timer Event End Event Error Event
Sequence flow • Connector between two elements of a process • Visualized as an arrow Default flow Sequence flow Conditional flow
Gateways • Control the flow of execution (if, else) • Visualized as a diamond shape, with an icon inside (gateway type) X O + Parallel Inclusive Exclusive
Exclusive Gateway (XOR) • Model a decision in the process • Follows a single outbound path
Parallel Gateway • Model concurrency in a process • Follows multiple outbound path
Inclusive Gateway • Combines the exclusive and parallel gateway
Tasks • Action that occurs in a process • Send an e-mail • Call a Java Web Service • Request work to be done by a human • Visualized as a rounded rectangle User Task Service Task Script Task Loop Task
Sub-processes • Activity that contains other activities • Allow hierarchical modeling • Creates a new scope for events

EDH Electronic Document Handling @ CERN
The Need for EDH • Over 100 official procedures • Used by all CERN personnel • Over 250000 documents per year • Examples: • Purchase orders • Training Request • Holiday Request
e-business Annual Appraisal (MAPS) Automatic Small Order (< 500CHF) Contract Request End of probation period authorization End-of contract authorization Export Formalities request External Training Request Fire Permit Illness declaration Import Formalities declaration Inter-departmental funds transfer Internal Purchase Requisition Invoice authorization Leave Request Official Travel Claim Official Trip On-site Training RequestOpening of Post Request Overtime request Part-time working schedule request Payment to Third Party Pro-forma invoice request Request for an Advance Request to Access Computer Centre Request to Access Restricted Areas Request to Drive CERN vehicle Request to Enable/Disable Alarm Request to Import merchandise (EU or Switzerland) Request to Perform Maintenance Work Request to Purchase from Stores Request to transit the French/Swiss Tunnel Request to use Forklift Truck/Tractor/Crane School fees ReimbursementSkills Inventory Subsistence Claim Sundry Expenses Claim Telephone Subscription Request Temporary Labour request Travel To Home Station “CERN’s EDH enables staff to focus on CORE activities by minimizing the overhead of business processes”

Signature Event Signature event is a task for interacting with people, who are asked to approve or reject an electronic document BPEL4People: “WS-HumanTask”(definition of human tasks and notifications)
Typical signature functions • Find who can sign • Assign signature to a person • Notify chosen person • Interact with signature processing service • Choose another person in case of absence / inactivity • Skip signature if person already signed • Handle forward / postpone • Return a result
Signature Targets • Specific person • - John Doe • Group of people • - leave-admins • Role/Right • - Department Head
Signature Roles • Could be hierarchical (e.g. Group Leader) or nominated (e.g. Safety Officer) • Have target(s) • DepartmentHead(IT) • SafetyOfficer(NICA) • CollaborationLeader(CMS, JINR) • Valid during a period of time • Have a priority
Rights Hierarchy • At CERN, one role can give many rights… • Group leaders are responsible for signing financial documents, signing leave requests of people they supervise, signing personnel action forms etc… • To reduce their workload managers may delegate part of their rights to other persons • For example, a group leader may want that purchase requests were signed by his deputy • A hierarchy of rights is needed to support such partial delegation of rights • May not be a problem for smaller organizations
Signature: Rights hierarchy Role(Group Leader) Personnelrights Financialrights Right to signleave requests Right to signovertime claims Right to signofficial travels Right to signpurchase requests

Signature Replacements Who can sign if the main responsible is away or does not respond? • Same role, lower priority • Deputy • Supervisor • Nobody: • Assign back to the first person • Stop workflow, notify responsible persons • Skip signature (in certain cases)
Signature Time-out Time-out is a maximum delaywhich a document can waituntil escalating the signature At CERN: Typically 3 days, but could be shorter or longer depending on the nature of the document • Sometimes time-out is not applicable (examples: requestor’s signature, DG’s signature, ...)
