TECHNIQUES FOR PLANNING AND SCHEDULING
The technique used for project scheduling will vary
depending upon the project's size, complexity, duration,
personnel, and owner requirements. The project manager
must choose a scheduling technique that is simple to use
and is easily interpreted by all project participants.
PROJECT SCHEDULING
BAR CHART
METHOD
Bar Chart Method
The Bar Chart Method is a visual tool
used to represent project schedules.
It displays tasks or activities as
horizontal bars along a timeline,
showing the start and end dates of
each task.
The basic modeling concept of the bar chart is
the representation of a project work item or
activity as a time scaled bar whose length
represents the planned duration of the activity
EXAMPLES
OF
BAR CHART METHOD
ADVANTAGE
AND
DISADVANTAGES
Overview
Provides a clear visual representation
of the project schedule, allowing
stakeholders to quickly understand
the timeline, task durations, and
progress.
04.
Task Tracking
Easily track the status of individual
tasks and their completion relative to
the project’s overall timeline.
04.
Ease of Use
Simple to create and understand,
especially when compared to more
complex project management tools.
Tools Availability
Can be generated using common
tools like spreadsheets (e.g., Microsoft
Excel) or specialized software (e.g.,
Microsoft Project, Smartsheet).
Task Duration
Clearly displays the start and end
dates for each task, helping with
accurate scheduling.
04.
Relationships
Allows for the visualization of task
dependencies, helping to understand
the sequence of tasks and any
potential impacts on the schedule.
04.
ADVANTAGE
AND
DISADVANTAGES
Complex Projects
May become unwieldy and less
informative for large projects with
many tasks and dependencies. The
chart can become cluttered, making
it hard to interpret.
04.
Changes
Once created, it might not
automatically reflect changes in
project scope or delays unless
manually updated. This can lead to
inaccuracies if the project deviates
from the plan.
04.
Priorities
Does not show task prioritization or
the critical path explicitly without
additional annotations, which can be
a limitation for identifying the most
crucial tasks for project success.
Limited Integration
Typically, it doesn’t include detailed
resource management features, such
as tracking resource availability,
workload, or conflicts.

GANTT / BAR CHART
Gantt charts have been a
fundamental project management
tool for over a century, and it’s easy
to understand why. They provide a
visual overview of project tasks and
the timeframe in which they need to
be completed.
Steps to Create a Project
Bar Chart (Gantt Chart):
Identify
Project Tasks
Break down the project
into manageable tasks
or work packages.
Each task should have a
clear deliverable and
estimated duration.
Define Task
Duration
Estimate the time
required for each task.
Consider holidays,
weekends, and resource
availability.
Set Task
Dependencies
Determine which tasks
are dependent on others.
For example, Task B might
only be able to start once
Task A is complete.
Arrange Tasks
in Sequence
Arrange tasks in a logical
sequence based on their
dependencies. Some
tasks may run in parallel,
while others may need to
be completed
sequentially.
Plot Tasks on
a Timeline
Draw horizontal bars to
represent the start and
end dates of each task.
Longer bars mean longer
tasks, while shorter bars
represent tasks that take
less time.
Identify
Critical Path
Determine the longest
sequence of dependent
tasks, which dictates
the shortest time in
which the project can
be completed.
Track Progress
Update the bar chart
periodically to reflect
completed tasks and any
changes to the timeline.
Bar charts help monitor
delays and adjust plans in
real-time.
Software for Creating Bar Charts
(Gantt Charts)
Microsoft Excel or Google Sheets
Microsoft Project
Trello with Gantt Chart Plugins
Smartsheet, Monday.com, Asana and etc.

ADVANTAGES OF CPM
1. ENHANCED PROJECT MANAGEMENT
Because the Critical Path Method breaks
large tasks and objectives into smaller parts, it
can help project managers to plan projects more
thoroughly. Project Managers can divide large
and complex goals into achievable task and mile
stones. This simplifies the project and helps
everyone to understand their roles.
2. CLEAR IDENTIFICATION OF
CRITICAL TASK
Critical Path Analysis enables project
managers to identify the most critical task
within a project. They can then rank the
tasks in order of priority, ensuring that
complex tasks get the attention they need.
This prevents the project from becoming
delayed because the team has overlooked
important task.
3. PRECISE
SCHEDULING
The critical path method separates critical and non-
critical tasks so that project managers can schedule
them more effectively. They identify the essential or
high priority tasks and outline them in the plan so that
project participants don’t overlook them. This keeps
the project running efficiently.
4. ACCURATE DETERMINATION
OF PROJECT LENGHT
Time management is essential for
meeting project deadlines and
preventing them from over-running.
The critical path analysis approach
helps to streamline the time
management of a project by
determining its duration. In addition,
project managers can compare
expectations with actual progress.
5. BETTER WORK PRIORITIZATION
Identifying the critical path helps project
managers clarify priorities and
determine the float of each task. Float
also known as slack, measures how long
a task can be delayed before it impacts
the completion date. Critical Path tasks
have zero float, while non-critical
activities have positive float.
Determining the float of each task helps
teams assess priorities. The lower the
float, the higher priority.
DISADVANTAGES OF
CPM
1. MAY OFFER LACK OF FLEXIBILITY
The Critical Path Method works well
when the tasks have predictable
timings. One downside of such
meticulous planning is that a project
manager may find that there is little
flexibility in the schedule for
unexpected events and
contingencies. It can also be hard to
adapt to new types of projects and
tasks that the project manager and
team are unfamiliar with.
2.GREATER POTENTIAL FOR DELAYS
Because the critical path method focuses on
the critical aspects of a project, project
managers may overlook non-critical
elements. This could lead to delays in these
aspects of a project. This can lead to the
entire project running overtime.
3. INCREASED COMPLEXITY
Dividing tasks into simpler jobs can lead to
the creation of a critical path diagram that is
excessively complex. Managing software's
entries can become time consuming because
it requires the identification of individual
tasks. The level of detail involved in applying
the critical path analysis approach to every
large project could make it challenging to
communicate to team members and
stakeholders.
4. STEEP LEARNING
CURVE
Critical Path Method is very
meticulous so to someone who is
new to the concept, it can seem
too complex and daunting to
learn.
