ANSWERS | 2026
The Project Network - Answers -A flow chart that graphically depicts the sequence,
interdependencies, and start and finish times of the project job plan of activities that is
the critical path through the network.
Terminology - Answers -- activity
- Merge activity
- Parallel (concurrent) Activities
- Path
- critical path
- event
- Burst activity
Activity - Answers -For project managers, an activity is an element of the project that
requires time. It may or may not require resources. Typically an activity consumes time -
Either while people work or while people wait. Activities usually represent one or more
tasks from a work package. Description of activities should use a verb/noun - f.ex.
develop product specs.
Merge activity - Answers -This is an activity that has more than one activity immediately
preceding it (More than one dependency arrow flowing to it).
parallel activity - Answers -These are activities that can take place at the same time, if
the manager wishes. However, the manager may choose to have parallel activities not
occur simultaneously.
Path - Answers -A sequence connected, dependent activities.
Critical path - Answers -When this term is used, it means the path with the longest
duration through network. If an activity on the path is delayed, the project is delayed.
Event - Answers -This term is used to represent a point in time when an activity is
started or completed. It does not consume time.
Burst Activity - Answers -This activity has more than one activity immediately following
it (more than one dependency arrow flowing from it).
Two approaches - Answers --Activity-on-Node (AON)
-Activity-on-Arrow (AOA)
, Activity-on-Node (AON) - Answers -a network diagram in which nodes designate
activities
Activity-on-Arrow (AOA) - Answers -a network diagram in which arrows designate
activities
Basic rules to follow in developing project networks - Answers -1. Networks flow from
left to right.
2. An activity cannot begin until all preceding connected activities have been completed.
3. Arrows on networks indicate precedence and flow. Arrows can cross over each other.
4. Each activity should have a unique identification number.
5. An activity identification number must be larger than that of any activities that precede
it.
6. Looping is not allowed (in other words, recycling through a set of activities cannot
take place).
7. Conditional statements are not allowed (that is, this type of statement should not
appear: If successful, do something; if not, do nothing).
8. Experience suggests that when there are multiple starts, a common start node can be
used to indicate a clear project beginning on the network. Similarly, a single project end
node can be used to indicate a clear ending.
There are three basic relationships that must be established for activities included in a
project network. - Answers -1. Which activities must be completed immediately before
this activity? These activities are called predecessor activities.
2. Which activities must immediately follow this activity? These activities are called
successor activities.
3. Which activities can occur while this activity is taking place? This is known as a
concurrent or parallel relationship.
Forward Pass - Earliest Times - Answers -1. How soon can the activity start? (Early
start - ES)
2. How soon can the activity finish? (Early finish - EF).
3. How soon can the project be finished? (Expected time - TE)
Backward Pass - Latest Times - Answers -1. How late can the activity start? (Late start
- LS)
2. How late can the activity finish? (Late finish - LF)
3. Which activities represent the critical path (CP)? This is the longest path in the
network which, when delayed, will delay the project.
