Croton Enterprises has worked out the activities, duration, and predecessors for its new project to create a new drink for the local Trinidad and Tobago market and for export to the Caribbean market. It wants to launch this new product to coincide with the carnival period in Trinidad and Tobago.

Draw a network diagram based on the above

A project consists of the following activities, predecessors, and duration. Each activity has a finish-to-start relationship.

Activity	Predecessor	Duration
A	-	4
B	A	5
C	-	9
D	C	11
E	B, D	6
F	E	7
G	FD	9
H	G	8
I	H	9

List all paths with their durations and identify the critical path using the enumeration method- show all markings

Establish a forward and reverse path throughout the network.

For each activity complete the following table.

Activity	Duration	EST	EFT	LST	LFT	Total Float	Critical Activity
A
B
C
D
E
F
G
H
I

Where EST is the activity's Earliest Start Time

Where LST is the activity's Latest Start Time

Where EFT is the activity's Earliest Finishing Time

Where LFT is the activity's Latest Finishing Time

Show the critical path using the forward and backward paths method. You may colour code it.

You have decided to reduce some activities:

D from 11 to 7

C from 9 to 6

H from 8 to 3

Using the enumeration method and theabovenew durations mentioned, redo the paths and determine the critical path. It is not necessary to redraw the network, but use the new durations and outline the critical path- showing all workings.

What are three (3) tools and techniques used for determining activity durations in project schedule management outlining their usefulness?

What are the challenges that are experienced in estimating activity duration in the country in which you reside? Highlight any tools and techniques that you are aware that we use in the State in which you reside and what sources of information are available.
