Not so long ago, there was only US mail and the telephone for people who needed to stay in touch. But in the last 10 years, there has been an explosion in the numbers and types of communications tools that can be used to keep your team together and keep important stakeholders informed of project and/or company progress.
Many still revolve around the land-line telephone because it is such a universal installation. But as computers and wireless installations have become increasingly more prevalent, communications technology that uses these platforms have entered and revolutionized the field.
The ability of these more recent platforms to let people share graphics in real time and the ability, of some, to allow that all important "face-to-face" type of meeting is dramatically changing how some businesses communicate, boosting their productivity, and dramatically cutting costs.
Due to the newness of some technologies, there can be reliability and interface issues that still need improvement, but the rapid rate of technology advancement and provider innovation is quickly eliminating these issues.
Some of these technologies include: classical and suped-up conference calls and videoconferencing; podcasts; webinars; Instant Messaging, just to name a few.
