Question

The following is a jumbled list of the four steps in structured systems analysis that were presented in the text:

I. Define the future logical system.
II. Document the current logical system.
III. Study the current physical system.
IV. Design the future physical system.


Which of the following is the logically correct sequence of steps?
A. II, IV, I, III
B. III, II, I, IV
C. III, II, IV, I
D. II, I, III, IV

Answer 1

The correct sequence of steps in structured systems analysis is to study the current physical system, document the current logical system, define the future logical system, and then design the future physical system, which corresponds to the sequence B. III, II, I, IV.

Step-by-step explanation:

The logically correct sequence of steps in structured systems analysis is first to study the current physical system (III), which is an important analytical step in both solving problems and thoroughly understanding the current operations and physical components of the system. After understanding the current physical setup, the next step is to document the current logical system (II), which involves creating a representation of how the system operates logically regardless of its physical implementation.


Once the current system is well understood, the next step is to define the future logical system (I), outlining the improved or new system's logical operations. Lastly, design the future physical system (IV) involves creating the physical specifications for the new system based on the previously defined logical requirements. Therefore, the correct sequence is B. III, II, I, IV.
