Process Modelling

Definition

Process Modelling is a technique used to visually represent how work is performed within an organization — showing the sequence of activities, decision points, roles, inputs, and outputs that make up a business process. Process models may represent the current as-is state or the desired to-be state. They help stakeholders understand how work actually flows, reveal inefficiencies, and provide a foundation for requirements definition and system design.

Inputs

• Defined process scope with agreed start and end points
• Stakeholder input from process performers, owners, and subject matter experts
• Existing documentation, SOPs, or prior process maps
• As-is analysis findings and improvement objectives

Outputs

• As-is process model showing current workflow with roles, decisions, and handoffs
• To-be process model showing the improved or redesigned future state
• Identified bottlenecks, redundancies, risks, and automation opportunities
• Inputs to requirements definition, system design, and change management

When to Use

• Improving or redesigning business processes before or during system implementation
• Implementing new systems where process context is needed to define requirements
• Addressing operational inefficiencies, compliance gaps, or legacy process debt
• Supporting change management by making the future state visible and communicable

When Not to Use

• Simple, informal processes where a lightweight description is sufficient
• Highly discretionary work where steps cannot be standardized
• When the process is already optimized, stable, and well understood by all stakeholders
