It is not uncommon to see a project failing to achieve its mission of creating a facility witin the specified cost and time. Hardly few projects get completed in time and within original costs.
The factors contributing to these overruns are outlined below:
Inadequate project formulation
Poor field investigation, inadequate project information, bad cost estimates, lack of experience, inadequate project analyses, poor investment decisions.
Poor planning for implementation
Inadequate time plan, inadequate resource plan, inadequate equipment supply plan, inter-linking not anticipated, poor organization, poor cost planning.
Lack of proper contract planning and management
Improper pre-contract actions, poor post award contract management.
Lack of project management during execution
Inefficient and ineffective working, delays, changes in scope of work and location, law. There can be endless reasons for non-fulfillment of project objectives. Failures can be due to unforeseen natural calamities like earthquakes, floods and natural disasters. Failures can also result from deliberate attempts made by manipulators during the feasibility stage by incorporating inaccurate time and cost estimates with a view to secure business or start a project. These in-built intentional inaccuracies can lead to unrealistic objectives and thus create problems during the implementation stage. But, the main cause of such failures can be attributed to the cost estimation failure and management failure.
