Martin Lehmann developed a troubleshooting guide for missing 'Expert' properties in Capella, aiming to improve user self-service and reduce support overhead. Working within the DSD-DBS/capella-collab-manager repository, he authored detailed documentation in Markdown, including an illustrative image and step-by-step instructions to help users re-enable advanced modeling features. His approach focused on clarity and accessibility, ensuring that users could independently resolve configuration issues without direct support intervention. The work demonstrated depth in technical writing and a strong understanding of Capella’s settings, though it was limited in scope to documentation rather than code or bug fixes during the reported period.
