John is a scheduler in ABC Company. He has to plan an activity for the schedule models. Which
of the following activities will he use to make the schedule models? . Each correct answer
represents a complete solution. Choose all that apply.

A.
Hammocks

B.
Critical path scheduling

C.
Flags

D.
Tasks

Explanation:
An activity is an individual component of work that is logically linked to other activities to outline the
schedule. Its key characteristics include an overall duration based upon the resources applied to it
(manpower, material, and equipment), a start and completion date that is tied to a work calendar,
and an association with other activities (predecessor and successors). Following are the various
types of activities in schedule creation: Tasks: A task is an activity that needs to be accomplished
within a defined period of time. Milestones: A milestone is the end of a stage that marks the
completion of a work package or phase, typically marked by a high level event such as
completion, endorsement or signing of a deliverable, document or a high level review meeting.
Flags: Flags shall occur at appropriate intervals of approximately each month. The flags shall be
located on the critical path and be incorporated into the baseline, all targets, and the current
schedule. Hammocks: Hammocks are a summary pseudo “activity” representing a group of
related activities that collectively cover some portion of a project.
Answer option B is incorrect. The Critical Path scheduling, or Critical Path Analysis, is a
mathematically based algorithm for scheduling a set of project activities.
