Find a legal copy, read the first three chapters on "Use Case Modeling," and you will immediately become a better requirements analyst than 80% of junior developers today.
Object-Oriented Software Engineering (OOSE) is a foundational methodology in computer science. Created by Ivar Jacobson in 1992, it introduced use-case-driven design to development. Many developers and students look for PDF copies of this classic text on GitHub repositories.
If you want to dive deeper into applying these classic principles to modern development, let me know: Find a legal copy, read the first three

Testing verifies that the implemented system matches the original requirements. Because the entire process is use-case driven, testers use the original use cases to generate black-box test suites. Jacobson's Lasting Impact on Software Engineering Many developers and students look for PDF copies
