With parallelization across different staff, the tasks can be efficiently pipelined.

Given the schedule:

1. Typist takes 2 hours per document.

2. Proofreader takes 1 hour per document.

3. Signer takes 0.5 hours per document.

The pipeline schedule shows:

After Doc 1 is typed (2 hours), it moves to proofreading, and Doc 2 starts typing.

By the time Doc 3 is done typing (6 hours total for typing 3 documents), Doc 1 would have been signed (3.5 hours total for Doc 1 to be signed after starting typing).

The critical path here is determined by the longest sequence in the pipeline, which is typing (6 hours for 3 documents).

Given the pipelined schedule provided:

The last document (Doc 3) finishes signing at 4.5 hours.
