How can mainframers actively grow their skills and see progress step by step? In this session, I’ll share personal experiences and lessons learned from helping newcomers and experienced professionals build skills that transfer across roles and compound over time. We will visualize a structured skills ladder with four levels: Foundational, Professional, Specialization, and Applied Knowledge. Using this framework, we will discuss concrete strategies to practice, track, and apply skills, turning structured learning into a visible journey that demonstrates progress, reinforces confidence, and supports continuous growth.
