Editing Project management software (section)

===Predecessors===
The first historically relevant year for the development of project management software was 1896, marked by the introduction of the Harmonogram. Polish economist [[Karol Adamiecki]] attempted to display task development in a floating chart and laid the foundation for project management software as it is today.<ref>[http://projectmanagementhistory.com/The_Harmonogram.html "The Harmonogram"], ''projectmanagementhistory.com'',</ref> In 1912, [[Henry Gantt]] replaced the Harmonogram with the more advanced [[Gantt chart]], a scheduling diagram that broke ship design tasks down for the purposes of Hoover Dam in early 1931.{{citation needed|date=March 2018}} Today's Gantt charts are almost the same as their original counterparts and are a part of many project management systems.
