Process maturity curve helps determine which management and improvement approach is most appropriate at each stage of process development.

• 0–2 | Low maturity
  Manual execution, chaos
  At this stage, the priority is to establish basic logic, roles, and sequence of work.
  The most relevant approach is process redesign.
• 2–4 | Medium maturity
  Formalized, partially managed
  Once the process becomes more stable and repeatable, the focus shifts to reducing variation, improving quality, and automating routine steps.
  The most relevant approaches are Six Sigma and RPA.
• 4–6 | Managed process
  KPIs, automation, management
  At this level, the process is already measurable and managed, so the priority is end-to-end control, monitoring, and continuous improvement.
  The most relevant approach is iBPMS.
• 6–7 | Mature process
  Digital, measurable, improved
  At the highest level of maturity, the focus moves to intelligent coordination across functions, predictive decision-making, and adaptive process management.
  The most relevant approaches are AI and process orchestration.
