Q.1 Define Project Management Information Software. Discuss the various
steps of PMIS planning.
Answer : Project Management
Information System (PMIS)
An information system is mainly
aimed at providing the management at different levels with information related
to the system of the organisation. It helps in maintaining discipline in the
system.
An information system dealing
with project management tasks is the project management information system. It
helps in decision making in arriving at optimum allocation of resources. The
information system is based on a database of the organisation. A project
management information system also holds schedule, scope changes, risk
assessment and actual results.
The information is communicated
to managers at different levels of the organisation depending upon the need.
Let us find how a project management information system is used by different
stakeholders.
Who needs information and why
|
Upper managers
|
To know information on all projects regarding progress,
problems, resource usage, costs and project goals. This information helps
them take decisions on the project. They should review the projects at each
milestone and arrive at appropriate decision
|
|
Project manager and department managers
|
To see each project schedule, priority and use of
resources to determine the most efficient use across the organisation.
|
|
Project team members
|
To see schedule, task lists and specification so that they
know what needs to be done next.
|
The four major aspects of a PMIS
are –
a. Providing information to the
major stakeholders
b. Assisting the team members,
stakeholders, managers with necessary information and summary of the
information shared to the higher level managers
c. Assisting the managers in
doing what if analyses about project staffing, proposed staffing changes and
total allocation of resources
d. Helping organisational
learning by helping the members of the organisation learn about project
management
Usually, the team members, and
not the systems administrators of the company, develop a good PMIS.
Organisations tend to allocate such responsibility by rotation among members
with a well designed and structured data entry and analytical format.

MB0049 – Project Management - 4 Credits
Assignment Set- 2 (60 Marks)
Note: Each question carries 10 Marks. Answer all the questions.
Q.1 Define activity, event, and path as used in network development.
What is a dummy activity? Describe the CPM model.
Answer : Activity : It is physically identifiable part of a project which require
time and resources for its execution. An activity is represented by an arrow,
the tail of which represents the start and the head, finish of the activity.
Event: The beginning and end points of an activity are called
events or nodes. Event is a point in time and does not consume any resources.
The critical path : is determined by adding the times for the
activities in each sequence and determining the longest path in the project.
The critical path determines the total calendar time required for the project.
If activities outside the critical path speed up or slow down (within limits),
the total project time does not change. The amount of time that a non-critical
path activity can be delayed without delaying the project is referred to as
slack time.
Dummy activity : An activity, which only determines the dependency
of one
activity on the other, but does
not consume any time, is called a dummy activity.
Logic Dummies
When the arrow diagram was
developed, there were two important problems associated with the method. The
first problem is that, since an arrow served to represent both the sequence and
duration of an activity, there are cases where showing sequence with a single
arrow is inadequate. The diagrams below shows several examples where a single activity
arrow cannot graphically express the sequence needed in an activities list.
The first example shows how Arrow
Diagramming has problems representing a sequence of activities where sets of
activities share some, but not all, of the prior activities. In this example,
Activity C has a prior of A and Activity B has both A and B as priors.
|
Activity
|
Prior Activity
|
|
A
|
None
|
|
B
|
None
|
|
C
|
A
|
|
D
|
A, B
|
Notice that when we try to create
an Arrow Diagram with this pattern the standard notation shown in the figure below
is incorrect.
The developers of the Arrow
Diagram created the "logic dummy." The logic dummy, an activity with
zero duration, links together activities whose sequence would otherwise not be
shown. To designate the dummy activity, a dashed arrow is used. As shown on the
figure below, the logic dummy is used to show the sequence between activity A
and D without the problem of linking Activity B with Activity C. One way to
know if a logic dummy is needed is to look at the activity list and find those activities
that share some, but not the entire set of prior activities.
Logic dummies are quite
versatile. Consider the example schedule shown below. Notice that Activities D,
E, and F do not all share the same set of prior activities. As a result, two logic
dummy activities are needed to properly show the sequence of tasks on this
project.
|
Activity
|
Prior Activity
|
|
A
|
None
|
|
B
|
None
|
|
C
|
None
|
|
D
|
A, B
|
|
E
|
B
|
|
F
|
B, C
|
Another example where logic
dummies are needed is shown below. Notice that Activities C, D, and E do not
share the same set of prior Activities. Since Activities C, D, and E do not
share both Activities A and B as priors, logic dummies are needed to properly
show the sequence using an arrow diagram.
|
Activity
|
Prior Activity
|
|
A
|
None
|
|
B
|
None
|
|
C
|
A
|
|
D
|
A, B
|
|
E
|
B
|
While the logical dummy is a very
useful tool to allow the arrow diagram to show all the required sequence
contained in a set of activities, the logical dummy should only be used when
necessary to show the proper sequence. The figure below gives an example of
when not to use the logical dummy.
In the diagram above, only prior
activity to Activity D is Activity A. In this case a logic dummy is not needed
between Activity A and Activity D. Logic dummies are one of the most common
problem areas in the Arrow Diagramming Method. In the next section, we
introduce the other area that causes problems with Arrow Diagramming, the
numbering dummy.
CPM.:
1. CPM is activity oriented i.e.,
CPM network is built on the basis of activities.
2. CPM is a deterministic model.
It does not take into account in uncertainties involved in the estimation of
time.
3.
CPM places dual emphasis on
project time as well as cost and finds the trade off. between project time and
project cost.
4. CPM is primarily used for
projects which are repetitive in nature and comparatively small in size.
