BASIC BPMNLearn basic BPMN symbols


I. Basic BPMN constructors

• The sequence flow defines the execution order of the activities

default flow – if all other conditions are false

conditional flow – used if the condition holds true



• Start event and end event – where flows begin and end.

start end



• An activity task is a unit of work and is the job to be performed. When marked with a symbol it indicates a Sub-Process, an activity that can be refined.

• A data object represents information flowing through a process such as a document, email, or letter

• A data store is a place where the process can read or write data such as a database or a filing cabinet. It exists even outside the whole process



• Pools and lanes represent responsibilities for activities in a process. A pool/lane may be an organization, a role, or a system. Lanes further subdivide pools or other lanes hierarchically.

I. Basic BPMN constructors - Gateways

• Exclusive Gateway - When splitting, it routes the sequence flow to exactly one of the outgoing branches. When merging, it awaits one incoming branch to complete before triggering the outgoing flow.

Xor



• Inclusive Gateway - When splitting, one or more branches are activated. All active incoming branches must complete before merging.



• Parallel Gateway - When used to split the sequence flow, all outgoing branches are activated simultaneously. When merging, parallel branches wait for all incoming branches to complete before triggering the outgoing flow

+



• Event-based gateway - is always followed by catching events or receiving tasks. Sequence flow is routed to the subsequent event/task which happens first



• Complex gateway - Complex merging and branching behavior that is not captured by other gateways

BASIC SIGSLearn basic SIGs symbols


III. Basic SIGs Symbols

• A non-functional requirement (NFR) softgoal

• An operationalizing method (cloud in bold)


III. Basic SIGs Symbols - Interdependency

• Direct “explicit” relationship (of softgoals)

• Indirect “implicit” relationship, correlation



• the following symbols are added to the arrows to further define the interdependencies

++ + - --

and appears, for example, as the arrow below+



• “to satisfice” means to be good enough• when one positive “+” symbol is added to an

arrow, this indicates that there is “help” or some “weak positive contribution” that helps satisfice a softgoal but does not satisfice it just by itself

+



• when two positive “++” symbols are added to an arrow, this indicates that there is a “make” or some “strong positive contribution” that can satisfice a softgoal by itself

++



• when one negative “-” symbol is added to an arrow, this indicates that there is a “hurt” or some “weak negative contribution” that hampers the achievement of a softgoal but does NOT by itself, prevent satisficing the softgoal

-



• when two negative “--” symbols are added to an arrow, this indicates that there is a “break” or some “strong negative contribution” that by itself, prevents the achievement of the softgoal

--


III. Basic SIGs Symbols

• Other important symbolsAccepted – softgoal is fulfilled (or chosen

to be implemented)Rejected/Denied – softgoal can not be

realized (or is chosen NOT to beimplemented)

! Critical – an important softgoal and/or – used to group (sub) softgoals

IV. Custom Operationalizing Methods

• Operationalizing methods (clouds in bold) can be further specified with custom symbols and labels

BPMN + SIGSLearn how to illustrate BPMN and SIGs together


V. Sample BPMN + SIGs together• The following symbol is used to link an

operationalizing method (from SIGs) to a business process activity task (from BPMN) and is referred to as an “operationalization target link”

• For now, we can link BPMN and SIGs with this symbol. In tutorial 3 - component representation, we discuss further refinements to this symbol
