Source selection is one of the major issue of the entire project. This must be taken care properly. The entire project time might get delayed due to the lack of resources. Even a project might lead to failure if there is no proper quality in the source. So sources must be taken into consideration in the initiation details. I mean that the sources must be taken into consideration when we are setting up the project duration. So during the estimation of the project time the supply of the source must be taken for estimation. So at that time PM will get some awareness regarding the source and he can get to know the situation. We can take all necessary steps for source in execution phase but we should get clarity about it in initiation phase. This lead to the efficient progress of the project. During the execution phase it will be easy for planning the resources and the project would be completed perfectly in time without the delay. As we say that prevention is better than cure. So prior judgement would be good enough to deal with the emergencies.
