There’s little time left over to find out what industry is doing, let alone develop courses to teach it. Nor do they have experience building and operating highly distributed systems. There are two factors: course enrollments, which show what students are studying, and course completion, which may reveal skills in high demand.

At first, companies simply tried to downsize their existing systems (remember Windows Mobile?) The winners were companies like Apple that created systems and interfaces that treated the mobile device as a primary means of user interaction. The art of modern development is orchestrating these systems to complement each other.

Due to separated systems that handle different parts of the process, the view of the process is fragmented. While some data comes from modern systems with APIs, other data stems from older systems that generate log files, and some data originates from external vendors. On top of that, the data sources are inconsistent.
