BPMN BPMN defined
edit
By the BPMI (The Business Process Management Initiative) developed a set of standards called the Business Process Modeling Notation (BPMN - Business Process Modeling Notation). Trying BPMI Notation Working Group over two years, in 2004 released the BPMN 1.0 specification. After BPMI incorporated into the OMG, OMG standard BPMN2.0 launched in 2011, has been redefined to BPMN (Business Process Model and Notation). The main objective of BPMN is to provide some symbols are easily understood by all business users, from the analysis of the profile creation process to achieve these business processes, until the end-user management and monitoring. BPMN also supports provide an internal model can generate executable BPEL4WS. Therefore, the emergence of BPMN, make up the business process from design to process development gap.
BPMN defines a
service flowchart
(Business Process Diagram), the operational flowchart of a flow chart (flowcharting), which was designed for creating a flowchart graphical models of the business process operations. A business process model (Business Process Model), which refers to the definition of the execution order of activities flow controller (flow controls) consisting of the graphic object (graphical objects) consisting of a mesh of FIG graphical object includes a movable (acticities) for .
BPMN BPMN specification Profile
edit
BPMN is the BPM and workflow
modeling language
one of the criteria.
In my previous article <On numerous workflow specification> talked about an important specification --BPMN workflow modeling language. First direct view of the normative content of BPMN V1.01, more than 200 pages of content variety, a lot of details. As a beginner to see disoriented, now we offer to help beginners clarify ideas, clear grasp of the overall BPMN specification.
1. What is BPMN
First BPMN specification is published by the Standards Organization BPMI .BPMN 1.0 specification was released in May 2004. This specification shows more than two years of efforts BPMI organizational results. The main objective of BPMN is to provide understandable by all business users a set of
markup languages
, including business analysts, software developers and business managers with the watchdog. BPMN also supports the generation of executable BPEL4WS language. Therefore, BPMN between business process design and process implementation to build a standardized bridge.
BPMN defines the
business process diagram
, flowchart based technology, at the same time a reduction of the business process for creating graphical models operation. FIG mesh model business process is a graphical object, including activity (it can be said work) flow control and defined sequence of operations.
2, BPMN foundation
Operational flowchart of a series of graphical elements. These elements simplifies the development model, and business analysts look very familiar. These elements each have their own characteristics, and similar to most modelers. For example, the activity is rectangular, with the proviso that diamond. It should be emphasized: the development of BPMN motivation is to provide a simple mechanism when creating business process models, but also capable of handling complexity from business processes. To deal with these two conflicting needs is to mark the graphical aspects of the organization classified as a specific category. There is provided a small fraction of labeled category to
a flowchart of operations
of the reader can easily identify the type of element in order to understand the basic pattern. There are four basic types:
1) stream object
2) connection object
3) Lanes
4) labor information
Below an explanation
Stream object:
There are a flowchart of a traffic stream object three core elements. These three stream object is
Event --- an event described by circles indicate what happened during a business process. Events affecting the flow of the process, there is generally a reason (
trigger
) or impact (result). Based on their impact on the process, there are three events: the beginning, middle and an end event
--- activity is represented by a rounded rectangle activity, it is a general term of the work to be processed. Activity may also be a non-atoms of atomic (larger particle size may be a combination of a plurality of activities from the activity). Type of activity include: tasks and sub-processes. Subprocess pattern in the middle of the bottom plus a small plus sign (+) to distinguish.
Condition Condition --- represented by the familiar diamond, for branching and merging flow control sequences. Further, it can be used as a conventional choice, further comprising a branching and merging path. Marker given its internal
control flow
type.
Connection objects:
The connection object stream objects together form the basic structure of a business process. This feature provides three connection object is:
--- stream sequence with a sequence flow of the solid arrow with a solid line, and the order of execution for a given activity. Note that "flow control" is a term generally not used BPMN
--- message message flow stream by a broken line with an arrow indicates the opening, is used to describe (two independent business actors
business entity
message flow between the transmitting and receiving traffic or role). In BPMN, two separate pools on behalf of two participants.
--- represents a correlation associated with a dotted line arrow for linking the relevant data, text, and other artificial stream object information. Association for input and output of the exhibition.
Lanes:
Many modeling techniques make use of the concept of the active lane into different categories to describe the visualization of responsibilities and duties of the different participants. BPMN supports two major components of the lane.
A participant pool --- pool described process. It can be seen as a pattern different from the other container pool series of events, generally used in the context of B2B.
Road --- channel which is subdivided the pool, may be vertical or may be horizontal. Road is also used to organize and categorize activities.
Labor information:
Artificial context information is added to the business process modeling as information notes, to facilitate the art understand, the current specification version BPMN predefined three types of artificial information:
Data objects
--- a data object is to show how activity is needed or produce data. By associating them with the
connected activities
together.
Group --- a group represented by a rounded rectangle of dotted line, for the purpose of recording or analysis, but does not affect the order flow.
Notes --- Notes is a mechanism for a modeler to provide additional text information for readers BPMN diagram.
Value 3, BPMN modeling
Development of BPMN is an important step to reduce the number of business modeling tools and marking faults that already exists. BPMI Organization for Standardization demonstrate the existence of a number of tags and professional experience, and to find the best ideas from these different markers in the formation of a standard
markup language
, many markup languages, including UML, Activity Diagram, UML EDOC Business Process, IDEF, ebXML BPSS, RosettaNet and Event-Process Chains and so on. A good standard modeling notation will reduce confusion between business and IT users.
Another driving force driving the development of BPMN is made out of history by the business people from the needs of business process modeling
system designed to
isolate the processes described and executed, it is necessary to convert the existing business process model for the implementation of the model, and for this conversion process owners is error-prone and very difficult.
In order to reduce fault modeling technology, the development of BPMN important goal is to create a business-oriented process modeling notation to IT-oriented execution of a bridge language. The following is BPMN graphical objects mapped to BPMN v1.1 wall chart.
BPMN BPMN elements
edit
For BPMN marked, some unanimously recognized basic elements. Containing core comprising a set of events, including the activity and the gateway stream object (flow objects), containing sequence flow, connected objects and associated message stream including (connecting objects); and a data-containing object, including text annotations and group artifacts (artifacts).
BPMN is a prominent part of the emphasis on the type of elements are called lanes. The elemental composition of the pool and lanes.
FIG lane is a graphical container for partitioning a set of activities with other pool activities. Events become automatic unit the entire business process. Lanes are used to organize and categorize activities, it is a sub-partition within a pool.
