ommunication skills play a vital role in project management. It is one of the mandatory soft skill that a project manager should have. Project managers should have the ability to convey the ideas clearly and effectively and should also allow the team members to speak openly and honestly. It is the key to success in areas such as software development where people are involved. Each project should have a good communication plan. Each project can have a same or different method for delivering the information. The communication plan includes the type of information the project manager delivers and the timing of the release and distribution. The methods of communication can be in many forms such as emails, written reports, conversations, meetings. Communication plays a major role when it comes to mergers & acquisitions (M&A) performance. Using project management tools like project logs, progress reports, and periodic reviews can help better communication and responsible documentation of individual and teamwork. By documenting and following this process can evaluate the progress of the project and team members. This, in turn, enables regular and systematic description and evaluation of individual contributions and overall team performance. The regular documentation of individual input helps to push all team members to act ethically throughout the project, that is, to contribute their fair share of work to the project. The frequent use of documentation helps to cultivate the habit of reflection in action by enculturating students to the practice of regularly examining individual and teamwork and constantly evaluating the amount and quality of work done. It also facilitates frequent reflection on strengths and weaknesses demonstrated in individual and teamwork, lessons learned during the project, and possible ways to work more closely and efficiently as a team in the future. Literature Review Belzer (2004) discussed the importance of Communication skills for the project managers. According to him, Communication skills are one of the mandatory skills for the project managers and they should have the ability to express the ideas clearly with their team members for the successful execution of the project. Jerome Kanter and John J. Walsh mentioned in their article that Lack of communication with management is the main reason for project failure. Several workshop attendees referred to the lack of communication within management — “what the project manager tells the functional manager, what the functional manager says, and what senior management hears appear to be different>GET ANSWER
