I do agree with this statement because the aspects listed are crucial because of their significance. Information distribution is very important because project team members or at least those who should know something must know it. Lack of awareness of something by one person can cripple the entire project execution phase depending on what the information is. Members need to be one the same page because this is a team effort. Synchrony cannot be achieved if people are missing crucial information that they must know. Solicitation is important because getting the right information is key to moving forward in a project execution. There is always that you can learn but all you need is a certain amount of info or the pertinent information in order to solve a problem or move forward with something within this phase. Managing vendors is extremely important as well because even though you may be on track , if your suppliers cannot deliver as expected, then your work will be futile because you need the materials to do your tasks. Source selection is important because you need to know what you can rely and what you can’t. All of the mentioned aspects of the execution phase are very important. A mistake in any of these parts will be detrimental to the whole project. This is how you know whether they are the most important aspects of the execution.
