The same process may be described very differently by different people.
Operations may focus on day-to-day activities, control teams on risk points, and IT on system interactions. New approvals, exceptions and applications added over time can make the process increasingly difficult to understand.
Process modeling creates a common reference.
What should a process model show?
Depending on its purpose, a model may include:
- Start and end points
- Process activities
- Roles and responsibilities
- Decision points
- Parallel flows
- System interactions
- Exceptions
- Data and document flows
- Controls and approvals
The best process model is not the most detailed one; it is the one that provides enough clarity for the decision it needs to support.
Excessive detail can make a model harder rather than easier to use, especially in daily practice.
Is process mapping the same as process modeling?
The terms are often used interchangeably in daily practice.
But process mapping usually focuses on higher-level activities and general flow, while modeling can add roles, rules, systems, decisions and exceptions in a more structured way.
A process map may be enough for simple communication.
Digitalization, automation or system development usually requires a more detailed model.
What does BPMN provide?
BPMN offers a standardized notation for modeling processes with common symbols.
Activities, events, gateways, parallel flows and roles are defined through a shared visual language.
It is particularly useful when business and technical teams need to work from the same representation.
Not every process needs advanced BPMN detail. The purpose should determine the depth.
Why distinguish As-Is and To-Be?
As-Is describes how the process operates today.
To-Be defines how it should operate in the future.
A To-Be design may:
- remove unnecessary activities,
- change responsibilities,
- simplify approvals,
- run activities in parallel,
- introduce system integrations,
- automate manual work.
The gap between As-Is and To-Be makes the scope of change concrete.
How does Process Mining complement process modeling?
Process modeling usually represents the defined or target process.
Process mining reconstructs the actual flow from system records.
Comparing the two can reveal:
- variants not present in the model,
- unexpected returns,
- skipped activities,
- different sequencing.
Process modeling creates a shared view; process mining helps test how closely that view matches real operations.
Where is it used?
Typical uses include documentation, improvement, digitalization, automation, system development, business analysis, compliance and training.
Where should organizations start?
First define why the model is being created.
The same process does not need the same level of detail for an executive presentation, operational documentation and software development.
The useful question is not “How detailed should the diagram be?” but “Which decision should this model help us make?”
