The fourth annual Telstra Productivity Indicator had 700 Australian respondents with 313 coming from the public sector.

More than 70 per cent of both private and public sector respondents were in the process of adopting Cloud computing over the next 12 months while 69 per cent of companies in the private sector had invested in e-commerce and self-service facilities.

In addition, 70 per cent of private and public sector respondents indicated they were investing in video conferencing and collaboration products.

Telstra network applications and services executive director, Antony de Jong, said that self-service facilities such as bill settlement could mean a "win-win situation" for company productivity. "If the bill is right the first time then you don't face all the costs of the organisation dealing with the complaint and doing the work to correct the bill," he said.

Video conferencing and collaboration offerings are becoming more popular in the public sector because of travel savings, faster business decisions and opportunities to connect with other federal or state departments in different parts of Australia.
