.Open Exercises and Quizzes on the Critical Path Method
. Simple Example
You and a colleague are working on a project that has a main
program and two independent classes.  Once the initial test program
is written you can start on the two classes (A and B say) and
develop them without tripping over each other.  Once the two
classes have passed unit test then you can start on the main
program that depends on them.
.Table #        Description     Duration(Days) Predecessors

.Row 2	Develop A	1	1
.Row 3	Develop B	2	1

. A JAD Meeting 1
Before you can start a Joint Application Development --(JAD)
meeting you must Email the participants and prepare the Audio Visual aids --(AVs)
and before you can send the Email you need to prepare the information
in the Email and arrange the room.  You can't prepare the information
or the $AVs without preparing the agenda for the meeting.  Before
you arrange the room and prepare the agenda you need to get 
approval for the JAD meeting from the participants.  And before you can get approval you need to make contact with the participants.

Here is a table of activities, what numbers do you put in the "Predecessors"
column:
.Table #	Description	Duration(Hours)	Predecessors
.Row 1	Contact people	1	?
.Row 2	Get approval	5	?
.Row 3	Arrange Room	4	?
.Row 4	Prepare Agenda	11	?

. A JAD Meeting 2
Draw an Activity Diagram of the above activities.
. A JAD Meeting 3
Calculate the earliest times of each event.
. A JAD Meeting 4
Calculate the latest times of each event.

Calculate slack and highlight the critical path.
. Planning a Training Session
Towards the end of a project an important activity is to train the
users in using the new system.  The table describes the activities
needed.
.Table #	Description	Duration(Hours)	Predecessors
.Row 1	Invite users	1	-
.Row 2	Study manual	5	1

.Row 6	Practice	1	5
.Row 7	Training	3	3,6
.Row -	Done	-	7
.Close.Table

Draw the activity diagram.

Calculate earliest times.

Calculate latest times.

Calculate slack times for each activity and show the critical path.

. Planning a Training Session -- Version 2
Here is a different $WBS -- draw the diagram and do the $CPM on it.

. My First PHP Page
I wanted to allow students to search my CS372 pages.
To do this I needed an HTML form and a PHP script.
Problem: I didn't know any PHP.  Here are my activities for
the first 3 iterations.

Use UML Activity diagrams and the critical path method
to work out how much time this project will take
and which activities are critical.
. Setting up a Seminar
The seminar committee has a lot of activities it must do
to prepare for a seminar.   How much lead time and what
activities are critical?

.Row -	Done	-	3,4,8,9,10,12,13
.Close.Table
Use an activity diagram to check the above table for logical errors.
Correct and use the Critical Path Method to work out
the earliest time the seminar can be ready.   Then work
out the latest times and the critical path.

. Starting a Masters Project
In the CSCI Department at CSUSB many graduate students finish their
Masters degree by tackling a realistic project -- for example a wireless
system for a hospital that lets doctors submit prescriptions directly to
the pharmacy for later pick up or delivery.  But all have a similar
starting process
