Software engineering includes activities beyond programming. Three implementation issues are particularly important and often not covered in programming textbooks. Which three are they?

User interface design - designing screens and interaction flows

Reuse - making as much use as possible of existing components or systems

Host-target development - developing on one computer and executing on another

Algorithm selection - choosing the most efficient algorithm for each operation

Configuration management - managing the different versions of each software component

Correct Answer

(1) Reuse - making as much use as possible of existing components or systems

(2) Configuration management - managing the different versions of each software component

(3) Host-target development - developing on one computer and executing on another

Explanation

The three key implementation issues highlighted are: (1) Reuse - most modern software is constructed by reusing existing components or systems; (2) Configuration management - during development, many different versions of components are created and must be tracked; (3) Host-target development - production software typically does not execute on the same computer as the development environment. Algorithm selection and UI design are important but are not the focus of this section.
