Aston Martin relies on third-party suppliers who need to be kept in the loop with company developments if the car-maker is to be able to react swiftly to changes in the market. Callow believes his SharePoint collaboration tools help the company do that.
"Why wouldn't we do that down the supply chain? Federation within the supply chain can help us shorten the development cycles of the particular product we are dishing out, which happens to be luxury sports cars," says Callow.
Steve Shakespeare, EU software director at Intel, says the chip giant has the same ethos.
"We have teams in Israel and in the US that have to collaborate together and they have to collaborate electronically. It's not an option to use paper and we have an enormous number of security systems that secure the intellectual property that we hold within the organisation.
"So increasingly, collaboration in many respects is old, but things like video collaboration - it's a great way to be more productive in the business."
Shakespeare says the CIO's role is in adopting consumerisation as a corporate strategy for improving work processes. Data security has to be maintained, even though information is flowing outside the company.
The NHS's Powell is well aware of the sensitivity of data within his organisation, which has to process a huge amount of personal information about its patients.
He has a well-defined approach to managing where that data goes, in terms of security protocols, but this has to be matched with some people management skills too.
Powell recommends that security protocols have to be communicated to all users and that they must acknowledge that they have understood them and will undertake to abide by them.
"Our tactical approach at the moment is to be crystal clear about the sacrosanct nature of patient information. So, people really need to understand that certain data isn't supposed to exist on these things and they are for convenience only," he says.
Powell allows certain types of corporate data to be held on employees' own devices, but he insists that the IT department has the ability to wipe that device. This means the employees' personal documents, pictures and other media will also be wiped.
"Staff need to be crystal clear when they use a personal device for work that they are at risk of losing a whole lot of personal data if they lose a device. They have to sign something to say that they agree to that in advance," Powell says.
Powell thinks that employee awareness of the security impact of processing company data through a personal device has to go even deeper. He says that employees have to be made aware of the potential impact that losing certain data could have on their organisation and take individual responsibility for it.
