Redesigning process modeling for efficiency and adoption
Problem Statement: Our target users — business professionals and citizen developers — struggled with process modeling in our tool. It was complex, error-prone, and required guessing steps instead of being guided, making adoption difficult.
Business Needs: High support ticket volumes showed that users were struggling with the existing tool. To reduce support costs and remain competitive, we needed a simpler, more intuitive modeling experience that lowered the learning curve and improved usability.
My Role: Alongside a colleague, I led UX strategy and facilitation across design, product, and engineering. Guided research, prototyping, and validation that delivered a SUS improvement of +20 points.
Timeline: 8 months
Discovery Phase
Testing: As part of our commitment to continuously improving the product, the research team conducted a live user study of the main user journey.
Findings: This evaluation revealed 10 critical usability themes, including:
- A confusing overview and difficulty modeling processes.
- Misunderstanding error icons as delete actions.
- Ambiguous terminology, especially in the adding menu.
Impact: These findings directly informed the redesign strategy, enabling the team to prioritize improvements that would have the greatest impact with the available team capacity.
Step-adding workflow in the original interface
Figuring it Out
Workshop: We facilitated workshops with designers, developers, and product managers to co-create solutions. Together, we mapped challenges, tested early user flows, and explored different solutions.
Key Outcomes:
- Identified critical usability gaps in existing flows.
- Prioritized improvements to modeling experience and guidance.
- Aligned teams on a shared direction.
- Laid the groundwork for low-fidelity mockups for validation.
Evaluative Research
Testing: We conducted comprehensive testing to validate the new design. Initial studies involved participants with no prior product knowledge, recruited via Respondent, followed by live system testing with Beta customers, large clients unfamiliar with the updates, and partners at an SAP event.
Findings:
- Users rated the new design as a major upgrade.
- Terminology was seen as more intuitive.
- Usability was rated much higher than before.
Results and Next Steps
Metrics: The redesign delivered a measurable impact on usability and user satisfaction:
- SUS Score: 62 → 86 (+24)
- NPS: –11 → +33 (+44)
- Fewer support tickets, smoother onboarding.
Next Steps: To ensure continuous improvement, we launched an in-product survey to capture real-time customer feedback and integrated analytics to track usage patterns and uncover opportunities. Upcoming releases will deliver incremental updates based on these insights, further refining the product to align with evolving customer needs.
Learnings: This project demonstrated the importance of early cross-team alignment, which accelerated decision-making and reduced downstream rework. It also highlighted the importance of prioritizing and acting on feedback, since it creates a reliable foundation for product improvement.
