Onboarding and ramping up new-generation developers in the mainframe environment presents significant challenges due to the steep learning curve and the disconnect between modern development practices and traditional mainframe systems. Artificial Intelligence (AI) offers transformative solutions to these challenges by providing personalized learning pathways, AI-powered code assistance, and intelligent debugging tools. AI can enhance knowledge discovery through smart search capabilities, facilitate virtual mentorship, and support collaboration among developers. By leveraging AI, organizations can create a more supportive and efficient onboarding process, making it less daunting for new developers to become productive in the mainframe world. AI's role in analyzing work patterns, offering contextual recommendations, and providing performance analytics further empowers developers, ensuring a smoother transition and quicker integration into mainframe teams.
