I was a secretary previously and can understand what headaches we have whenever we need to organise the annual or monthly conference and meeting. We have offices located all over the world and it is very costly for the company to bring all the management staff together.
So, we normally resort to video conferencing and only give the senior management an annual retreat cum conference once a year. To get the maximum effectiveness of video conference, of course, we need to invest in good set up. Take a look at what this site has to offer and I hope it helps your company to organise the next video conference.
