IoT has become one of the latest trends in the enterprise, with nearly 40% of the 2016 CIO 100 are currently developing or delivering the Internet of Things within their organisations.

The increase in IoT has remained a focus for CIOs and organisations within their business strategies. CIO UK looks at how CIOs are utilising the digital technology to reduce costs, get ahead of their competitors and increase staff productivity.

"In our Tourism and Leisure business: Digital disrupting the industry by leading the way with a shift to cloud-based integrated solutions optimised for Mobile and Multi-Channel whilst taking advantage of RFID, IOT, wearable and Mobile emerging technologies. This has resulted in considerable revenue growth, more reliable solutions and improving margins in a competitive market."
Simon Kniveton, Orridge CIO

"Many of the deliverables in the last 12 months have been internally focused around either cost efficiency or enhanced productivity. We have several highly innovative propositions that have undergone significant development and investment in the last six to 12 months, a few of which should be ready for mainstream launch later this year, leveraging IoT, geolocation and other aspects of digital enablement in combinations that have not yet been seen in this industry."
Adam Gerrard, Yodel CIO

"We have a number of wearables under evaluation, ranging from watches and fitness monitors to smart fabrics and ECG security devices. These all benefit from IoT activities that we are working with to record, and act on, based on events such as IFTTT and microservices that we develop. Smart technologies that can help in the office but can also be applied elsewhere include iBeacons and large-scale NFC readers. These technologies, coupled with innovations in blockchain technology, open up opportunities in asset tracking and fraud detection."
David Smoley, AstraZenecaUK CIO

"We have a brilliant head of innovation, Iain Roche, and we've been jointly looking at a number of emerging technologies, particularly around data and IoT. So, for example, Germany has been working on Industrie 4.0 for a while now, predominantly focused around IoT for the manufacturing industry, but we are looking at how this can be applied not just to the construction of the railway, but also how sensors will play a big part in the operation of the railway in 10+ years' time.

"On the data front we have been experimenting with an SME on IoT and how we can use data not just generated by HS2, but from across the internet to gain insight and better decision-making for a weather event, for example, that could impact the operation of the railway."
James Findlay, HS2 CIO

"We already utilise wearables and the IOT in a number of areas, the most recent being the use of a device implanted in the body that monitors the heart and transmits data back to our consultants via a special pillow when the patient is at home sleeping (a first in the UK last year)."
Joanna Smith, Royal Brompton and Harefield NHS Foundation Trust CIO

"At its simplest level, we are going to use IoT sensors embedded in concrete to determine thermodynamic characteristics. This info is then stored in the cloud and used to refine the algorithms to improve accuracy. The benefit of this is a higher quality build for our customers and an improvement in efficiency of our operation."
Richard Gifford, Carillion CIO

"Our prospective customers we have developed the ability to search across the group for the right home in the right area while checking affordability online. We are also working on several angles to benefit from IoT. These include management and control of components in a home and common areas, as well as methods for helping vulnerable customers with dementia or disabilities, for example."
Neil Beckingham, Your Housing Group CIO

"Our Innovation team has won numerous awards for its work using in-pipe robotics. They have also recently won a multi-million pound project to trial wider use of sensor technology and IoT to deliver 'smart gas networks'."
Andrew Quail, SGN CIO

"The energy industry is changing, and now presenting a great for use of big data technologies to analyse customer consumption data that before smart meters was not available. At Ovo we have 20% or our base in smart meters already, transmitting consumption data to us up to every 10 seconds. We have developed a smart IOT device that connects to the meter via zigbee and gives us data on real time, we store everything in Nosql and time series databases and analyse it using machine learning."
Mariano Albera, Expedia CTO, then Ovo Energy CTO
