Activity - Creating a PERT chart
Match the task to the blanks in the PERT chart. 
The following is a list of the six tasks which are used to fill the blanks.
•     	Mix mortar and lay bricks
•     	Load bricks
•     	Clean up
•     	Pour footings
•     	Footings curing
•     	Dig trench.
The PERT chart is a sequenced list of tasks on arrows which connect the nodes (circles) which are numbered 1 to 9. Starting after node 1 is the task 'Enquiries, orders' which connects to node 2 where there are 3 branching arrows. The first arrow from node 2 is labelled 'Wait bricks' and connects to node 3. There is a blank 
(blank 1) after node 3 for a text to be filled in. This connects to node 7.
The second arrow from node 2 labelled 'Clear site' and connects with node 4. From here a downwards arrow has a blank (blank 2) which then connects with node 5. 
The third arrow from node 2 is labelled 'Order concrete' then also connects with 
node 5. 
After node 5 there is a blank (blank 3) to be filled in prior to node 6. After node 6 there is a blank (blank 4) to be filled in prior to node 7. Now all paths connect via a blank (blank 5) to node 8 which is followed by a blank (blank 6) and then to node 9 which is the final node in the PERT chart. 
Which tasks from the list match which blank?
The correct answers are:
1.     	Blank 1 - Load bricks 
2.     	Blank 2 - Dig trench
3.     	Blank 3 - Pour footings
4.     	Blank 4 - Footings curing
5.     	Blank 5 - Mix mortar and lay bricks 
6.     	Blank 6 - Clean up
