In this second part of his interview with CIO Australia, newly-appointed Defence CIO Dr Peter Lawrence discusses why chief information officers must work closely with other C-level execs, and the effect of social media on IT organisations.\nAs Defence\u2019s CIO, Dr Lawrence is leading a team responsible for delivering several initiatives under Defence\u2019s Strategic Reform program aimed at saving the department $20 billion over 10 years. The success of these initiatives under the reform program will depend on how well C-level executives at Defence work together.\n\u201cA lot of the programs we are running now are about us [Defence\u2019s IT organisation] being able to deliver to Defence a much better platform to run its business; a more scalable, more reliable platform that will support the ADF in its role.\n\u201cYou can\u2019t do that unless you are closely integrated with the business,\u201d he says. \u201cIf you are not working with the CEO, the CFO, marketing and procurement teams, then you are going to be lost.\u201d\nDr Lawrence says he works closely with heads of [personnel] services, the CFO, and other C-level managers to understand how to deliver the best outcome for Defence.\n\u201cA CIO that isn\u2019t part of a [particular] business probably won\u2019t be the CIO for very long,\u201d he says. \u201cI work closely with the CFO [to] understand what Defence needs and what we are able to spend and [ask], 'Are we efficiently spending the money that we have on ICT?'"\nThe social media effect\nDr Lawrence agrees the rise of social media is changing the nature of how CIOs deal with often unstructured information coming from multiple sources.\nHe was previously CIO at Origin Energy, a company that \u201cused Facebook and Twitter as a business-enabler to engage with customers, take feedback and respond etc,\u201d he says. \u201cThat was a very deliberate strategy and part of our marketing and corporate communications.\u201d\nDefence is not using social media as a business tool, he says. \u201cWe do have some internal blogs but you wouldn\u2019t see that in the public domain."\nGeneral David Hurley, chief of the Defence Force, uses social media as a communication tool to talk to people in the armed services, he says. Serving personnel also use social media tools to connect with their families when they are on duty.\n\u201cIt depends on what industry you are in but I think for a lot of industries, particularly if you are in a customer-facing industry, it\u2019s pretty critical to understand how you use that [social media] to engage with your customers.\n\u201cIt\u2019s a two-way feedback mechanism \u2013 how you engage, how you take feedback, respond to it, how you react and communicate major outages and other things,\u201d he says.
