Chapter 9 Systems Analysis and Design 9-1 Chapter 9 True-False 1 . Process specifications show the decision-making logic and formulas necessary to transform process input data into output. T (p. 306) 2 . While process specifications produce a precise description of what is accomplished, they are not detailed enough to validate the system design. F (p. 306) 3 . Process specifications are always produced for input and output operations, such as a read or write operation. F (p. 306) 4 . Process descriptions may exist on a form but not within a CASE tool repository. F (p. 306) 5 . Process logic may be represented as either structured English, a decision table, a decision tree, or a formula. T (p. 307) 6 . Selection data dictionary entries become IF. ..THEN. ..ELSE structured English statements. T (p. 313) 7 . Iteration data dictionary entries become simple structured English statements in a sequence. F (p. 313) 8 . When structured decisions are not complex, an appropriate technique for analyzing the decision process is the use of semi-structured English. F (p. 308) 9 . Besides the obvious advantage of clarifying the logic and relationships found in human languages, structured English has another important advantage as a communication tool. T (p. 312) 1 0 . If communication is unimportant, structured English is a viable alternative for decision analysis. F (p. 312) 1 1 . It is important to develop decision tables in a logical, systematic approach. T (p. 315) 1 2 . Decision tables can become very burdensome because they grow rapidly as the number of conditions and alternatives increase. T (p. 319) 1 3 . If conditions are mutually inclusive, they can be written in extended-entry form. F (p. 319) 1 4 . The number of decision table columns and rows necessary decreases while the understandability decreases. F (p. 319)

Chapter 9 Describing Process Specifications and Structured Decisions 9-2 1 5 . Decision trees are most often drawn on their side, with the root of the tree on the left-hand side paper, branching out to the right. T (p. 319) 1 6 . It is useful to combine conditions and actions when drawing decision trees. F (p. 320) 1 7 . A square node indicates a condition, and a circle indicates an action. F (p. 320) 1 8 . In drawing the tree, identify all conditions and actions and the order and timing of these. T (p. 320) 1 9 . Use structured English when complex combinations of conditions, actions, and rules are found. F (p. 322) 2 0 . Use decision tables when there are many repetitious actions. F (p. 322) 2 1 . Use decision trees when the sequence of conditions and actions is critical. T (p. 323) 2 2 . The logic of a parent process shows the sequence that the child diagram processes must be executed in. T (p. 324) 2 3 . All the process specifications for the entire data flow diagram are consolidated and included in
