Our last trivia quiz explored the legacy of mainframe pioneers, and this week we’re going to continue looking into the lineage of skills in mainframe professional practice, examining how early design and operational decisions shaped the way mainframe expertise is taught, shared, and sustained over time. 

However, unlike our last quiz, which looked at individual pioneers, this one is more focused on practices rather than personalities, and how those practices continue to influence modern mainframe work. The emphasis is on professional discipline, institutional knowledge, and the systems of learning that allowed the platform to scale and endure.

Take the quiz and test your knowledge!

1. The rise of structured programming in mainframe environments primarily improved which training outcome?

 
 
 
 

2. Apprenticeship-style learning emerged early in mainframe teams largely because of which constraint?

 
 
 
 

3. Which role historically served as a key knowledge bridge between hardware design and application behavior on mainframes?

 
 
 
 

4. Why was extensive documentation considered a strategic asset in early IBM mainframe projects?

 
 
 
 

5. Why did backward compatibility become a defining element of mainframe workforce stability?

 
 
 
 

6. Mainframe virtualization initially gained traction because it enabled which workforce-related benefit?

 
 
 
 

7. CP-67 and later VM systems encouraged which professional skill to become more common among mainframe practitioners?

 
 
 
 

8. Which programming language was explicitly designed to reduce workforce fragmentation by supporting scientific, commercial, and systems programming on a single platform?

 
 
 
 

9. Which organizational practice became common in mainframe environments and supported long-term skill development?

 
 
 
 

10. What long-term workforce effect resulted from the mainframe’s emphasis on operational reliability?
