Tapping into never-before opportunities
The IT-OT integration space is, therefore, gaining in importance. It presents never before opportunities within the industry. These include the critical ability to ensure predictive maintenance that lowers downtime and costs while simultaneously improves safety and customer satisfaction. Take the simple every day case of a faulty plant compressor that produces abnormal vibrations. OT will have noticed it and would have done a comparison with vibration patterns from scores of other compressors. It would have reached the conclusion that the compressor needs replacement. This is, doubtless, the right conclusion. But today’s systems do not allow operations teams to quickly look up the action taken the last time a compressor failed, the spares were used for repairs, the materials are available in the inventory for current repairs, the lead time suppliers need, are the skills to repair the compressor available in-house or must be requisitioned from a supplier. All these mapped against how critical the compressor is to current operations and a forecast of near-future demand. To do this with unerring accuracy, IT-OT integration must become a reality.
While OT generates readings, IT provides an update on how best to manage it so that:
- Efficiency improves
- Downtime is reduced
- Costs are lowered
- Risk to assets is minimized
- Customer satisfaction is improved
Shining a light on the road ahead
In the excitement of undertaking IT-OT integration, Utilities must keep two critical factors in focus: First, create a roadmap – identify use cases that ensure higher efficiency that guarantee the overall success of the IT-OT integration initiative; second, place inordinate stress on security – ERP systems entail opening enterprise systems to suppliers, support partners and business associates in order to ensure velocity of business. This could lead to security issues.
As far back as 2007, the US government demonstrated how hackers could bring down power plants by injecting a mere 21 lines of code into SCADA networks1. In early 2016, a Western Ukraine Power Company reported2 that the power cut in December 2015 was caused by hackers sabotaging operations and management systems, impacting 80,000 consumers. As IT-OT convergence becomes everyday reality, cyberattacks and risk from malware will increase at equal pace, turning security into a real challenge that Utility organizations must manage.
No discussion on IT-OT integration can be complete without a mention of the need for cultural change management. While identifying the right use cases determines ROI and managing security is a must, it is organizational culture which is the hidden enemy of IT-OT integration. The people who manage OT and those who manage IT come from very different backgrounds. Their work environments are dramatically different and their mind-sets very dissimilar. Ensuring they work together as a team is a challenge organizations fail to adequately recognize.
At the bottom of this is the real pressure of profitability. While operational costs continue to rise, regulations prevent Utilities from increasing energy prices to meet those costs. Margins are becoming thin. The only way to improve margins is to improve operational efficiency—and this is where IT-OT integration becomes an unavoidable imperative.
