1)The entire success of a project in any organization totally depends upon the effective communication.Primary goal/role of a project manager would be to communicate properly across all the requires channels/peripherals.A successful project manager should showcase the real benefits of effective communication by taking a lead in making team prepared to lead by example.Effective project manager should not only be available/engaged in just speaking and hearing out the team members but should be in a situation to understand the complete context under any situation.A simple miscommunication in the project can lead to delay in the project deadlines/deliverables. With the advancement of technology , it is the primary job of the project manager to connect all the required dots,fill the gaps and make sure the right information reaches out to the right individual within the stipulates time.2)As per the case study,although Herb has been working as a full timer(has been acquainted with the company for quite long enough to understand all the existing intricacies) with doctorate in different aspects of manufacturing projects,I would say he might not be the right choice to play the role of a project manager.Herb lacks the following effective project manager primary roles a) sync-up with the team members b) maintain relational and communicative abilities across different teams.Herb with his capabilities and skill-set might not be able to finish the deliverables on-time for which an effective communication and team work would be required.It goes by the same principal Divide and Conquer,divide the tasks across the team members with suitable skill-sets followed by communicating the right information across the right channel.Before actually assigning the project management roles and responsibilities,it would be better if Herb can attend different PM courses along with attending regular meetings (knowledge share sessions) with the team members.3)Alice would have reached out via right channel so as to make Herb understand her requirements.It would have removed the unwanted miscommunication between the required parties.Bob would have maintained a straight talk with Herb and should have worked as a team to come up with the right output that removes the unwanted gaps.Daily stand-up meetings with the discussion about the ongoing updates would be fruitful.Frank, with the opinion of not being consulted or communicated regarding the purchase of the expensive materials cleared out the doubts by maintaining active communications with Betty.Betty would have placed the right procurement order if she would have been properly informed by Herb earlier.In my opinion,Agile methodology with a scrum master sharing the roles and responsibilities of a project manager along with regular stand-up meetings would help with the above mentioned issues.
