Identify the statement that is true in systems analysis and implementation practice (choose the single best true statement).

Introduction / Context:
Systems analysis and implementation terminology can be confusing. Choosing the single true statement requires knowing precise definitions for parallel runs, documentation boundaries, and organizational information flows. This question tests that conceptual clarity.

Given Data / Assumptions:

• Parallel run refers to operating the old and new systems simultaneously and comparing results.
• Systems analysis is a thinking and modeling activity that can be performed without computers.
• Information flows in organizations can be vertical, horizontal, diagonal, and networked.
• Documentation is layered: system documentation vs program/module documentation.

Concept / Approach:
System flowcharts depict system-level processes, data stores, and external entities; they belong to system documentation. Program documentation focuses on source code, algorithms, and program-level flow. Therefore, stating that a system flowchart is not part of a program documentation package is accurate.

Step-by-Step Solution:
Evaluate each option against definitions and practice.Option A misdefines parallel run; it is not about two terminals on one database.Option B is false—analysis relies on models/interviews and can be manual.Option C is false—information flows are multidirectional in modern organizations.Option D correctly distinguishes system vs program documentation.

Verification / Alternative check:
Implementation plans list “parallel run” as simultaneous operation/outputs comparison for risk mitigation. Documentation standards (e.g., system overview vs program specs) separate system flowcharts from program-level artifacts, confirming D as true.

Why Other Options Are Wrong:
A: Confuses the definition of parallel run. B: Computers aid analysis but are not a prerequisite. C: Overly absolute; ignores cross-functional flows. E: Invalid because D is true.

Common Pitfalls:
Treating “system” and “program” documentation as interchangeable; misremembering parallel run as a hardware/terminal configuration concept rather than a rollout strategy.

Final Answer:
a system flowchart is not a part of a program documentation package
