Scheduling 6 Flashcards
- In the PG, where are the ‘follower’ tasks?
They are the COLUMNS. The PRECEEDER tasks are the ROWS.
- A PRECEDENCE GRID can be developed from:
the TASKS named in each level of the WBS. Each PG becomes progressively bigger as the number of tasks increases.
- In the PG, where is the START and END?
START is on top of the PRECEEDER TASKS (rows), END is the last of the FOLLOWERS.
- In a PG, multiple X’s in a ROW mean that:
those tasks can be started simultaneously.
- In a PG, multiple X’s in a COLUMN mean that:
the TASK named by the column CANNOT begin until all its predecessor tasks have been completed.
- The purpose of the PG is to:
study and edit its data before attempting to draw it’s network.
- What are the applications of the PG?
A. To find REDUNDANT precedence relationships.
B. Identify potential ‘dummy’ tasks required for an AOA network.
C. Identify groups of tasks that can be safely be merged back into more general SUPER TASKS.
- In the PG, what is a LOOP?
When task A is said to follow task B, but task B is also shown to follow task A.
- In the PG, what is a MULTIPLE PRECEDENCE RELATIONSHIP?
When you have ROWS and COLUMNS with multiple X’s with an X at their intersection.
- When calling out the location of a task in the PG, you say:
(ROW, COLUMN)
- In an AOA diagram, rows and columns with mutiple X’s and an X at their intersection identifies:
potential ‘dummy’ tasks for the ARROW network.
- When a SINGLE STRING of X’s parallels the DIAGONAL of the PG and no X’s exist on either side of this string, the string identifies:
TASKS that could be grouped together into a SUPER TASK
- What is the purpose of a SUPER TASK?
To simplify the PG and reduce the total number of tasks.
- Why do SUPER TASKS work?
SUPER TASKS can be safely used because there are no ‘outside’ tasks linked to the intermediate tasks in each group.
