BIM 2 Flashcards
What are business processes
A business process is a collection of events, activities, and decisions that collectively lead to an outcome that brings value to an orgaization
What is business process management?
The science of overseeing how work is performed in an organization to achieve consistent outcomes. It is a body of methods, techniques, and tools to analyze buisiness processes. It is about the entire chain
What are the common categories of business processes ?
- order-to-pay
customer submits an order and ends with delivery and payment - quote-to-order
starts with customer requesting price quote, and ends with customer placing an order - Procure-to-pay
Starts with realizing a need for a product, and ends with delivery and payment - Issue-to-resolution
starts with customer raising an issue, and continues until issue is resolved - Application-to-approval
starts with request for certain thing, and ends with approval or denial
Ingredients of a business process
- events
events happen instantaneously - activities
activities have duration - decision points are points in time when a decision is made that affects business processes
Business process management lifecycle
- Process identification
Business problem is posed - Process discovery
The current as-is process model is looked at - Process analysis
The current process model is analyzed and issues are identified - Process redesign
The as-is model is turned into the to-be model - Process implementation
Perform changes required to move from as-is to to-be process - Process monitoring and controlling
Collect and analyze performance data on running process
Role of algorithm
Algorithsm can assign tasks, make processes more efficient , and reduce costs
Notation of BPM
- events are circle, with the first being a simple circle, intermediate event being double, and end event being bolded circle
- activities are represented by round rectangles
what are tokens in BPMN?
Tokens illustrate the progress of a given instance of the process. The current state of a process at that instant
What ar gateways
A gating mechanism allows or disallows passages of tokens
What are split gateways and join gateways?
split gateways are gateways that have single incoming sequence and several outgoing sequence. It splits the tokens
Join gateway are gateways that join multiple incoming sequences and has one outgoing sequence
What are exclusive deciisons?
Exclusive deciisnos are XOR gateways.
What are parallel decisions?
AND gateways
AND gateways split tokens into two which is then reached back at the end of the AND gateway join, where they join back to one. it waits for a token to arrive to merge into one again.
What is synchronization in AND Gateways?
The behavior of waiting for a number of tokens to arrive and then merging into one again
What is a deadlock in AND gateways?
We wait for a token to arrive from each branch. When one of the tokens does not arrive as the branch splits elsewhere and ends, a deadlock is created. It is fixed by ensuring that the AND comes back.
Inclusive decisions?
OR-Gateway
