Limitations of Network Diagram

Time wasting: use of Network diagram costs a lot of time to draw and may only for huge projects (Schwalbe 2010, p. 228).

Difficulty of Update: network diagram is not easy to update when changes happen and the drawer has to adjust changes by himself. It is also more difficult to determine a critical path in a network diagram. Network diagram shows finish to start relationships making it impossible to show lead and lag except by adding or subtracting times that makes project tracking difficult if not possible (Taylor 2006, p. 93-94).

Ease of making mistakes: It is so easy to make mistakes whenever wrong calculation of time or do not remember the formula

Difficulty of maintenance: Network diagram do not show time line for a project and large network require dedicated maintenance and analysis (NocêRa 2012, p. 264-265). It is very difficult to construct for large complex projects with numerous activities and dependencies and hard copy representation of such large network diagrams can be cumbersome. It is also more complicated since it entails more information (Patzak & Rattay 2012, p. 195-196).

Difficulty in production and distribution: Network diagram do not lead project managers to ease production or distribution.
