The History
• Henry Laurence Gantt's legacy to management is the Gantt
chart.
• Henry Laurence Gantt (1861-1919) was a mechanical
engineer, management consultant and industry advisor.
• Henry Laurence Gantt developed Gantt charts in the second
decade of the 20th century.
• Gantt charts were used as a visual tool to show scheduled
and actual progress of projects.
• Accepted as a commonplace project management tool today,
it was an innovation of world-wide importance in the 1920s.
• Gantt charts were used on large construction projects like
the Hoover Dam started in 1931 and the interstate highway
network started in 1956.
ABOUT GANTT CHARTS
• The chart is a graphical representation of
the duration of tasks against the
progression of time.
• The chart is a useful tool for planning and
scheduling projects.
• The chart is helpful when monitoring a
project's progress.
Planning and
Scheduling
• This chart allows you to assess how
long a project should take.
• This chart lays out the order in
which tasks need to be carried out.
• This chart helps manage the
dependencies between tasks.
Monitoring A
Project
• Here the chart allows you to see
immediately what should have been
achieved at a point in time.
• Also the chart allows you to see how
remedial action may bring the project
back on course.
Buzz Word and
Their Meanings
• Actual Cost for Work Performed (AC) Total amount spent on a task up to the
current date.
• Budget At Completion (BAC) - Overall
approved budget for a task.
• Budget - A fiscal plan of operations for a
given time period.
• Burden - Overhead expenses allocated for
a project's direct labor or material.
• Cost/Schedule Control System Criteria (C/SCSC)
- A set of 35 defined standards. Since 1967,
these standards have been used to ensure the
government that contracts are managed
properly. In December of 1996, these 35
standards were superseded by 32 earned value
management standards.
• Cost Variance - The difference between the
BCWP (earned value) and the ACWP (actual costs)
• Cost Performance Report (CPR) - A cost report,
generated monthly by the contractor to show cost
and schedule information.
• Cost/Schedule Status Report (C/SSR) - A report
used for smaller value contracts which don't
warrant the full C/SCSC, showing cost and
schedule.
• Demonstration Review (DR) - The first
formal review of a contractor's control
system to determine whether the system
meets C/SCSC requirements.
• Earned Value (EV) - Earned value is
synonymous with the term BCWP (Budget
Cost for Work Performed). The actual
measured performance; the value of the
completed work.
• Estimate at Completion (EAC) - A value
which represents the expected cost of the
project at completion. EAC shows the
actual costs to date plus the estimated
cost for completing the project.
• Estimate to Completion (ETC) - Represents
the value of the work required to finish a
task.
• Extended Subsequent Applications Review
(ESAR) - Performed instead of a C/SCSC
review when contractor conditions have
changed. (contractor moves, work moves
into a new phase, or when other changes
occur)
• Level of Effort (LOE) - Work which
doesn't yield a final product. Examples:
coordination, follow-up and other support
activities.
• Milestone - An important event.
• Organizational Breakdown Structure
(OBS) - A structure which shows work
responsibilities. The top level shows top
management and the structure is detailed
downward to the lower levels of
management.
• Statement of Work (SOW) - A document
describing the work to be done on the
contract.
• Work Breakdown Structure (WBS) - A
tree-like representation of the work to be
done on a project. The WBS graphically
shows the division of work.
