This Excel-based milestone trend analysis is an efficient graphical tool for tracking project milestones. It visualizes the trend of milestones and offers the possibility to identify resulting effects on the project completion date, so that countermeasures can be taken in time, if necessary. Due to its high information density and clarity, it is suitable for reports to the higher decision-making level. Since it records the development of milestones, it can provide reference points for extensive detailed analyses at the end of the project (lessons learned).
