Windows analysis refers to periods of time in which the project programme will be reviewed. The window periods need to be determined before any analysis is undertaken. Commonly on shorter project durations monthly windows would be used, whereas projects that run for a few years could have windows based on a two or three monthly windows. Once the window periods are agreed the analysis can be undertaken to analyse what happened in each window.
The various methods of delay analysis can be adopted to a windows based analysis, such as a Time Impact analysis using windows (SCL Protocol 2002), Time Slice Windows Analysis (SCL Protocol Ryder 1 2015) or an As-Planned v As-Built windows analysis.
