The convergence of IT (Information Technology) and OT (Operational Technology) can present several challenges:
- Management: in most of the company, IT and OT systems were managed by different teams, with different skills and expertise. It can be difficult to ensure that the two teams are being managed effectively and that the IT and OT engineers are working together effectively.
- Compliance and regulation: IT and OT have different compliance and regulatory requirements. It can be difficult to ensure that both systems are meeting all relevant standards.
- Understanding and process: both teams are talking different languages and have different expectations. There is long a learning curve to take in consideration if you start this journe. IT must understand OT and the other way around. This understanding must not be limited to technical aspects. The process must also be taken in consideration. For example, ITIL processes are not well known by most of the OT Teams.
For the reasons listed above, it's important to build a strong governance. You should have a dedicated team in charge of the convergence process, with clear roles and responsibilities and the right level of expertise in IT and OT.
And maybe the most important. A trust must be created between both teams.
