How do you know how much work have you completed of what you planned ?
There are three ways of doing it :
(1) Physical – Its a guesstimate, when nothing is available we use this
(2) Duration – (Time elapsed + Time left) is compared against Planned duration
(3) Units – (Effort spent + Effort left) is compared against Planned effort expressed in units.
Although this looks simple , it becomes complex where we have to deal with large number of activities. Deciding this beforehand saves time & effort in updating the information and delivering accurate reports.
