Managing Software Requirements: A Use Case Approach, Second Edition

Chapter 7. Systems Engineering of Software-Intensive Systems

Key Points

• Systems engineering is a problem analysis technique especially suitable for embedded-systems development.

• Systems engineering helps us understand the requirements imposed on software applications that run within the solution system.

• Requirements flowdown is primarily a matter of ensuring that all system requirements are filled by a subsystem or a set of subsystems collaborating.

• Today, the system design must often be optimized for software costs rather than for hardware costs.

In Chapter 6, we looked at business modeling, a problem analysis technique for IS/IT applications. Business modeling helps us determine what application we should build and where we should run that application, ...
