Through the e-mail communication I believe Jane was very clear in expressing what she needed from Mark. I think that she should have possibly asked him could he get the information to her no later than a specific date and time in order to give him an idea of how soon she really needs the information. This would ensure that he gives the information to her in a timely manner.
The voicemail communication made me feel like there was a sense of urgency in the materials that Jane needed. The pitch and tone kind of made me think that she is in desperate need of the materials from him or there is a sense of urgency. I think I would be more prone to attempt to get the materials to her if I were Mark.
The face-to-face communication is a great idea because if Mark has the materials already handy, then he can give them to her right then. She will not have to worry about missing her deadline. The only thing with the face-to-face communication shown in the resources is that her body language made her seem timid as well as her not seeming confident in what she was saying or asking for. I believe that she could have used a different tone that would have expressed to him how important it is for him to do his part to help her be successful at meeting her deadline.
I think that communication is essential to being successful when working on any project that requires other people to be involved. Communication helps to ensure that schedules are followed, deadlines are met, and projects are accomplishing the intended goals and outcomes. Without proper communication, the project could definitely fail.
