PERT is used for one time projects that involve activities of_________a.Non-repetitive natureb.Repetitive naturec.Continuous natured.Invalid in natur

Step 1: Break Down the Problem

We need to identify the correct characteristic of activities for which PERT (Program Evaluation and Review Technique) is used. This requires understanding the nature of projects suitable for PERT.

Step 2: Relevant Concepts

PERT is a project management tool designed for planning and controlling project tasks. It is particularly useful in projects that are:

• Complex with many interdependent tasks.
• Non-repetitive, meaning each project is unique and not part of a routine task.

Step 3: Analysis and Detail

When we consider each option:

1. Non-repetitive nature: This aligns well with PERT's purpose as it is used for one-time projects.
2. Repetitive nature: This is typically related to operations management rather than unique project planning.
3. Continuous nature: Also does not apply to PERT as it is not designed for ongoing operations.
4. Invalid in nature: This does not contribute to the understanding of PERT usage.

Step 4: Verify and Summarize

Based on the analysis, the most suitable description of PERT's intended use is that it is for projects involving activities of non-repetitive nature.

Final Answer

a. Non-repetitive nature
