What is a DROPLINE PROGRAMME ???

Dropline a simply a vertical line drawn on data date or current date when the progress is updated. Depending on whether the activity is ahead or behind the plan, this line will have dog-legged lags forward or behind. This is very simple way of repesenting progress and obviously quite good on wall chart etc. (Of course you can do it in computer as well).

The other variety of programme in this context will be reschedule programme where the data-date line is always vertical. Those activities progressing ahead of schedule will indeed be seen to complete sooner and those lagging behind will be seen to get completed late.
