Disadvantages ofcritical path methodCPM has many advantages and it has been able to supplycompanies using it a yardstick and a sensible assess of the time needed for thecompletion of the project. The main disadvantages of critical path method arelisted below.

Numerous disadvantages are as a result of the technical andconceptual components included in the CP analysis (CPA) process.-        TheCPA process can ended up complicated as the scope and extend the projectincreases. Too many interconnection activities can result in the networkdiagram getting to be very complicated. The hazard of making a mistake in calculationof the critical chain gets to be very high as the number of activitiesincrease.

–        Thetask of understanding the needs of the critical path get more complicated whenthere is more than one critical path in the project. In many circumstances,these ways might be parallel and bolster into a common node in the networkdiagram. It gets to be troublesome in these situations to distinguish thefinest utilization of technology and resources for the critical paths.-        Inmany cases, as the project advances, critical paths might alter and advance andpast critical paths may no longer be substantial and new CP have to berecognized for the project at regular interval. This suggests that the projectmanagers and project members have to always review the network diagraminitially made and identifying the moving and movement of the critical pathover time. –        Theuse of total float as a measure for assigning activities to their representative’spaths can become risky when analyzing as built plans. CPM is incapable tocalculate total coast on as a build schedule in which estimated dates have beensupplanted by actual dates.-        Inspite of the fact that CPM method is exceptionally important in the degree ofsubtle elements that it gives, modifying the system always can be cumbersomeespecially in the event that includes reallocation of resources an time.

–        Althoughof the broad utilize of CPM in organization the way in which it is used cancontrast essentially. Organizations that have a solid culture of timelycompletion might be utilizing the methodology in a more appropriate way whencompared to companies that utilize CPM as it were somewhat for planning andscheduling.
