Question

what are the disadvantages in using Earned Value and a PMIS?

Answer 1

The disadvantages are:

(i): Earned value does not take into consideration “quality”. While it may be possible that a project is scoring high on earned value performance scale it may also happen at the same time that quality of work is sub-par.

(ii) Planned value is considered as a baseline but there is an element of uncertainty involved when doing predictions. It may happen that a project is on schedule when earned value analysis is done but certain unforeseeable risks can delay the project at later stages.

(iii): In most of the cases earned value analysis is associated with high cost of implementation.

(iv) PMIS can be expensive in many cases because apart from the cost of the software there is the cost of implementation as well as maintenance.

(v) PMIS , in many cases, require multi-user access. While multi user access can lead to definitive collaborative benefits it can also lead to unauthorized viewing of sensitive project data.
