Developing Effective Visual Representations to Monitor Project Performance
Namhun Lee, Eddy M. Rojas · Construction Research Congress 2009 · 2009
During construction, project managers constantly review actual project performance and resolve any discrepancies between as-planned and as-built progress. However, it is not always easy to perform these activities since numerous individuals and parties are involved in a typical project. This is where visual representations may be helpful. Several charts and diagrams have been traditionally used in construction to visually track performance. This paper analyzes the advantages and disadvantages of traditional visual representations such as bar charts, network diagrams, line of balance charts, and S-curve graphs, and introduces a set of design principles for the development of non-traditional visual representations to effectively monitor project performance. The paper closes with examples of new visualization schemes built according to those principles.
