Time-Scaled Logic Diagrams:
* Represent activities with respect to a time scale (e.g., a calendar).
* Show logical relationships and durations in a visually aligned manner, aiding in analysis and reporting.
Common Misconceptions:
* They are not the same as pure logic diagrams (B).
* While often created using computer software, manual versions are also possible, so (A) is incorrect.
* They are not specifically for calculating activity durations (C).
PSP Study Guide References:
* The guide identifies time-scaled logic diagrams as a tool for better visualization of schedules, where activities align with calendar dates.
Conclusion: The correct answer is D, as time-scaled logic diagrams are drawn to align activities with a calendar.
