Question

Quizplus · Accepted Answer

The "sandwich rule" states that every process symbol should be placed between an input and output symbol, forming a "sandwich." This helps to clearly illustrate the flow of inputs and outputs in a process. Option A is incorrect because minimizing white space is not the main purpose of the sandwich rule. Option B is incorrect because annotations can be placed anywhere in the flowchart and are not limited to being between input and output symbols. Option D is incorrect because using too many different types of symbols can actually make a flowchart more confusing and difficult to read.
