I agree that all these factors are important for project success. Primarily, everyone in the project should be able to agree on the project goals. This is important because that way there is no discrepancies of some project members saying more or less could have been done. Communication is crucial in all aspects. From being able to build relationships with your peers, to being able to sternly communicate something. Communication is key. Developing clearly defined plans with assigned responsibilities I feel like it is a sub-category of the project goals, but nonetheless it is important. Managing the scope of the project is important because I think it is what keeps the project on track. Lastly, having managerial support is crucial because it does not only support that the company backs the project, but having support from a superior motivates team project members.
