This subject provides a general overview of the development
of project control techniques from bar charts through to
modern optimisation and integration (BIM). The origins of
specific techniques are discussed as separate subjects
Topics included in The History of Project Controls:
Origins of Schedule Management.The concepts used for project schedule
management have very deep roots. This paper traces the
development of the concepts most project managers take for
granted including bar charts and critical path schedules
from their origins (which are far earlier than most people
think) through to the modern day.
Origins of Bar Charting.This paper looks at the ancient Greek
and Egyptian origins of the concepts used by both
Priestly and Playfair as a starting point to develop
their charts which in turn led to the development of the
modern bar chart by the late 1800s.
Art:The origins of PERT and CPM. Research
into the origins of the mathematics and drawing styles
used in PERT and critical path schedules.
Art:The Origins of Hammocks and Ladders.Hammock
and Ladders are activity types that were developed in the
period 1961 to 1965. This paper outlines the development
of these useful scheduling assets an differentiates
Hammocks from LOE and Summary activities.

of communicating schedule data.(This
presentation will be developed into a full paper) The

did managers start using data to calculate project

a development of the 1950s.
