A Milestone chart highlights key checkpoints and can reveal delays or ahead-of-schedule achievements, but it does not depict detailed interdependencies among jobs.

Introduction / Context:
Milestone charts provide a high-level view of a project by focusing on significant events (milestones) rather than every activity. They are excellent for executive communication and quick health checks but are limited in how much logic they convey. This question probes what a milestone chart can and cannot do.

Given Data / Assumptions:

• We consider a standard milestone chart with planned vs actual dates.
• We assume the chart can mark slippages or early completions.
• No network logic (detailed dependencies) is shown unless supplemented.

Concept / Approach:
By comparing planned milestone dates with actuals, a planner can quickly see if a milestone is delayed or achieved early. However, a milestone chart by itself does not illustrate detailed precedence relationships among all underlying tasks; that is the domain of CPM/PERT networks.

Step-by-Step Solution:
1) Identify purpose: summarize key deliverable checkpoints.2) Compare planned vs actual marks to detect delay or earliness.3) Note that job-to-job logic is not explicit in a pure milestone chart.4) Conclude that highlighting delays is a core strength while interdependency depiction is not.

Verification / Alternative check:
Review any milestone dashboard: late markers are visible immediately; but you cannot infer complex sequencing without referring to a network or bar chart with links.

Why Other Options Are Wrong:

• Shows interdependencies of various jobs: Not inherently; needs a network diagram.
• Points out jobs going ahead of schedule, if any: Possible, but the question format requires exactly one correct choice; highlighting delay is the classic, emphasized use.
• None of these: Incorrect because milestone charts do surface schedule slippages.

Common Pitfalls:

• Expecting a milestone view to substitute for full dependency and critical path analysis.
• Using only milestone status without drilling into causes within the detailed schedule.

Final Answer:
Depicts the delay of jobs, if any.
