Gateways in Process Modelling, BPMN

What is a parallel gateway?

Divergence element 
- A parallel gateway used as divergence element indicates a point when activities (flow paths) must be carried out at the same time and in any order.
- represent by diamond shape with plus sign

Convergence element
- A parallel gateway used as an element of convergence allows you to synchronize (combine) parallel flows into a single path.


What is a data-based exclusive gateway?

Divergence element
- indicates that only one route can be taken from the various available.
- the decision will be taken after evaluating a business condition.
- represented by diamond.

Convergence element
- A data-based exclusive gateway used as convergence element enables joining routes into a single one.

What is an event based exclusive gateway?

Divergence element
- A point in the process where only one of many branches of the process can be selected.
- The decision is based on two or more events that might occur, rather than on a data condition (as in a data-based exclusive gateway).

What is an inclusive gateway?

Divergence element
- used when a point in a process enables one or more available paths (data-based).

Convergence element
- a converging inclusive gateway synchronizes the paths activated by the diverging inclusive gateway.

What is a complex gateway?

As an element of convergence
- is used to continue the next point in the process when a business condition is met

As an element of divergence
- is used to control complex decision points

Short Notes : Activities in BPMN
بِسْمِ اللّهِ الرَّحْمَنِ الرَّحِيْمِ
اللهم صل على محمد وآل محمد
السَّلاَمُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَبَرَكَاتُه



What is an activity, a task and a sub-process?

What are activities?
- Represented as rounded rectangles
- Signify the work performed by an organisation
- Uses resources such as time

Type of activities
- Task : atomic activity 
- Sub-process : compound activity

Task include :
- User
- Script
- Service
- Send
- Receive
- Manual

Sub-process include : 
- Embedded
- Reusable

> User task : an activity performed by a person or user with the help of system or software.

> Service task : activity performed by system without human intervention. 

> Script task : an activity that executes an expression.

Sub-process
- a compound activity included within a process (parent process)
- collection of activities
- logical sequences
- can be represented as collapsed or expanded.
- collapsed : sub-process detailed are not displayed
- expanded : sub-process detailed is diplayed
- two classification which are embedded and reusable.

Embeded - signifies the sub-process depends completely on the parent process.
> structurally part of the parent process
> Cannot contain pools or lanes
> Can only use a none start event
> All process data used in the parent process is directly accessible by the embedded sub-process.


Reusable - defined process like another business process diagram, and does not depend on the parent process.
> an independent process that can be called as a sub-process from different parent processes
> does not depend on a particular parent process and may be used in multiple business contexts without any alteration.
> can be a high level process or a sub-process

اللهم صل على محمد وآل محمد
(Allahumma salli 'ala Muhammad wa ali Muhammad)
سُبْحَانَ اللّهِ وَ بِحَمْدِهِ ، سُبْحَانَ اللّهِ الْعَظِيمِ
(SubhanAllahi wa biHamdihi, SubhanAllahil adzim)

Short Notes : BPM, What is a process?
بِسْمِ اللّهِ الرَّحْمَنِ الرَّحِيْمِ
اللهم صل على محمد وآل محمد
السَّلاَمُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَبَرَكَاتُه



What is a process?

ex,
> claims and complaints > provide better respones
> accounts payable > organize and process company invoices
> recruitment and selection > find attract and keep the best people on the market

Process :
> operation
> transformation
> series of activities

What is a pool and a lane?

pool
> a process is contained in a pool
> a container of a single process
> name of the pool can be considered as the name of the process
> sequence flows cannot cross the boundary of a pool

lane
> subdivision of a pool
> defines the staff roles or departments that carry out the activities
> a lane may be responsible for many tasks
> lane do not assign assign activities. They are an aid for carrying out the graphic consultation involved in the process.


What is an activity?

Activities
- represented by rounded rectangles
- signify a task perfomed within an organisation
- do not represent a state, function or event
- when an activity is completed, the next activity starts
- should be labeled with verbs


What is a sequence and message flow?

sequence flow
> represent the control of the flow and the sequence of activities
> are used to define the execution order of the flow objects: activities, gateways and events

message flow
> represent the communication between two processes through messages


What is a gateway?
> represented by a diamond shape
> used to control the divergence and covergence of the flow (split and merge)

divergence (data-based exclusive gateway)
> the flow where there is one sequence flow in and more than one sequence flow out
> indicates that one route can be taken from various available
> the decision will be taken after evaluation a business condition

covergence
> more than one sequence flow in and only one sequence flow out


What is an event?

events
> an events represents something that may occur during the course of a process
> 3 types of events depending on when they affect the flow
- start events (start of a process)
- intermediate events (represent events that may occur within a process)
- end events (end of a process)


اللهم صل على محمد وآل محمد
(Allahumma salli 'ala Muhammad wa ali Muhammad)
سُبْحَانَ اللّهِ وَ بِحَمْدِهِ ، سُبْحَانَ اللّهِ الْعَظِيمِ

Short Notes : Why is BPMN important?
بِسْمِ اللّهِ الرَّحْمَنِ الرَّحِيْمِ
اللهم صل على محمد وآل محمد
السَّلاَمُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَبَرَكَاتُه



Why is BPMN important?

BPMN
> standard
> simplicity (simple notation)
> power of expression (process can be described precisely)
> implementation

ex, Who will perform each activity in the processes?

- what are the risks if the process is not created with precision?
- what are the risks by not implementing the standards established by your company?
- have you realised how much time your company is wasting if the process is not standardized?
- how many tasks may have to be re-processed because the process is not clear?
- how much time could your employees waste to re-processing these tasks?
- how much time could your company waste by not hiring the right people?
- how much money could your company waste re-processing tasks and hiring the wrong people?
- what is the impact on your services and clients by hiring the wrong people?
- how much business could your company lose if the wrong people are employed?

BPMN allows to improve : 
> profits
> customer satisfaction
> employee satisfaction
> efficiency

BPMN is important because : 
- BPMN is a standard for diagramming business processes (it is not a methodology)
- facilitates communication
- allows the diagramming of processes END to END
- allows business-IT allignment


اللهم صل على محمد وآل محمد
(Allahumma salli 'ala Muhammad wa ali Muhammad)
سُبْحَانَ اللّهِ وَ بِحَمْدِهِ ، سُبْحَانَ اللّهِ الْعَظِيمِ
(SubhanAllahi wa biHamdihi, SubhanAllahil adzim)
سبحانك اللهم وبحمدك أشهد ان لا إله إلا أنت أستغفرك وآتوب إليك

BPMN
Business Process Model & Notation
> BPMN is a graphic notation that captures the logic of the activities, messages between the various participants and all information necessary for a process to be analyzed, simulated and implemented.

Process models
- Process are the most important asset
- BPMN is a set of figures to diagram process models
- Modelling your process is the first step

BPMN
> unified language
> executable business process
> general understanding

Benefits of BPMN
- shared understanding
- rich and precise semantics
- BPMN facilitates standardization of processes inside and outside an organisation
- BPMN developed by BPMI (Business Process Management Initiative)
- BPMN 1.0, 2004 (first version)
- OMG (Object Management Group) standard, 2006
- BPMN 1.1, January 2008
- BPMN 2.0, January 2011
