VULNERABILTY OF 5 PMLC MODELS AND MITIGATION STRATEGY
There are five Project Management Life Cycle (PMLC) models for managing different types of Projects but all of them follows the five process groups namely – scoping, planning, launching, monitoring and control and close out phases for sequencing the tasks. The difference lies only in the looping of these process groups depending on the complexity of the Project. The weakness of these models and mitigating strategies are discussed as follows for these models:
Linear –The five process groups will be followed in sequence as scoping – planning – launching – monitoring and control – close out but there is no feedback loop at any step. This model is generally used at times when solution and requirements are clearly defined, without too much scope changes. This model is unable to accommodate any change at any stage of the Project. For example – The design is continuously changing throughout the construction phases in oil and gas industry so, this model will cause project failure if applied. To overcome this issue the Planning team has to fix a deadline date for designing phases and Project Manager should closely monitor the development in this regard. 2.
Incremental –This model very closely resembles the linear model without any feedback loops where each phase releases some partial solution. As the Project is carried out in incremental manner there are chances to take longer time in finishing the Project, which will cost extra time and money. To overcome these problems Project Manager is required to fix strict timelines and accountability chart in place. Potential for any creep can be avoided by closely monitoring the budget and schedule at regular intervals. 3.
Iterative –In this model each process groups have feedback loop associated with them and after completion of any phase if Client is not satisfied the process can be repeated but the last step will provide only partial solution. Often there are...
