Expert Solution & Answer
Chapter 5, Problem 5.1E
Explanation of Solution
System Context:
It is important to model the system context because context models will show the environment which includes several automated systems. These models will help to get a clear view of the system that has to be developed and several other systems involved.
Errors:
The two possible errors that could arise if software engineers do not understand the context of the system are as follows:
- The software engineers may miss some functionality that has to be included for coordinating with automated systems.
- From the actual functionality, the design and development of the system must be deviated as some requirements may not be known properly.
