Demystify the nomenclature of ICS
The nomenclature and technical specificities can make operational technology (OT) difficult to understand. Within utilities, OT encompasses computing systems that are used to manage operations controlling equipment, instrumentation, assets, processes, and events.
Industrial control systems (ICS) are typically used in utility mission critical control sectors,
which includes supervisory control and data acquisition (SCADA) systems, distributed control systems (DCS), and other control system configurations such as programmable logic controllers (PLC).
The lines between SCADA, DCS, and PLC at times are blurred, depending on the actual implementation of ICS for each utility sector. Factors such as control timing requirements, geographic distribution, control complexity, and others can influence the design of the ICS.
- SCADA is often exclusively used in utilities covering long distance operations such as electricity transmission and distribution, natural gas distribution, and water distribution.
- DCS, highly integrated with the physical equipment, is often used in large power generation sites due to its reliable and high-speed local area network to handle large quantity input/output (I/O) processing.
In the context of this research, "ICS" is used to cover both components used generically across all utility sectors and those unique to one to one sector.

ICS has been supporting the core operations in utilities as the unsung hero
ICS, equally important as information technologies (IT), has been widely used across utilities to make operation automation possible. Through various communication systems, data and command are exchanged between the centralized control center and the equipment or instrument within plants or remote field sites. Here are many examples that ICS automation supports core operations in utilities.

Determine the risks of not modernizing and plan your long-term goals
Modernize your ICS with proactive planning instead of being surprised by reactive actions. The use cases of the ICS modernizations could vary for each organization. IT/OT leaders must start asking the following key questions to determine your risks of not heading down the modernization path.
- Is it safe to operate and what are the service reliability metrics ?
- Is the cost of maintaining the existing system sustainable?
- What are the key features missing from the existing system?
- Can you operate in compliance with current and future regulations?
- Do you get quality support from the vendor?
- Do you have a sufficient pool of resources internally and externally to support the existing system?
Source: Control Engineering, 2022.
The business case benefits must align with your long-term vision, and are driven by your organizational objectives. Tackle the plan holistically instead of piecemeal to modernizing and optimizing. An overall long-term strategy is often expected, and it is crucial to highlight how ICS modernization will help meet the overall objectives.
Develop a comprehensive cost-benefit analysis
An ICS modernization project is often part of a large utility digitalization program that consists of many components. The multiyear program involves implementing new systems or upgrading complex existing systems. Their interdependencies and interactive effects make it difficult to justify updating any one of them separately. In addition, not all benefits can be easily quantified, such as contributing to the net-zero pathways for utilities. The following example of a benefit and cost metrics can help build out your CBA and navigate for supporting the justification of your business case. Depending on the financial treatment, capital and operational expenses could shift if the cloud system is chosen.

Pitfalls to avoid when planning your project
- No resources lineups
Resources planning is critical. It is not just about project resources but also operational support resources and post-implementation vendor technical support. - No team collaboration
Regardless of the IT/OT organizational structure, not getting the right team from both IT and OT involved can lead to costly regrets. For example, without the security team and network subject matter experts' review, you might encounter security and network configuration blockers during implementation. - Security as an afterthought
Without selecting a security-by-design solution, your investment will be compromised and risk not being compliant with growing stricter regulations. - Overlook change management effort
Major modernization projects require dedicated effort to execute a change management plan including communication, process documentation, and training. - Not having a master plan
A common mistake preventing project success is not allocating sufficient time for planning and design. Without a well researched master plan of a phased approach, you might be setting yourself up for failure. - Assume a perfect-fit solution
Most vendor products will provide you with standard functionalities that have some flexibility of configuration. Customizations are required to fit your specific needs at times. Decide on the trade-offs and do not assume a perfect-fit solution.

Develop talent and foster collaboration to support modernization
Automation Federation and Department of Labor collaboratively developed a competency model specific to the automation profession.
Competency Model Clearinghouse, license, 2019; courtesy United States Department of Labor.
Collaboration between cross-functional experts is mandatory to the success of your ICS modernization project, regardless of your organizational structure.
There are more common competencies between IT and OT professions than differences, despite different priorities and educational backgrounds. For instance, in the area of infrastructure (5.4) and cybersecurity (5.6), many organizations have similar resources working on two parallel systems that have a lot in common. Collaboration between two teams can certainly benefit the organization, especially with the challenge of a labor shortage.
Developing a competency-based talent program for utilities is key to growing the talent pool. With the aging workforce, utilities need to establish succession plans across different levels of professionals. Systems become more complex than ever to support and maintain. Competency-based development can make sure future talent have versatile skill sets to support future automation capabilities.
Info-Tech Resources:
A change management plan is key to cultivating an open mind
Collaboration between IT/OT could be the biggest challenge in your ICS modernization plan. Despite the trend of IT/OT convergence across many industries, most utilities are not ready yet for organizational structural change. Often seen as having conflicting objectives, in reality IT and OT teams share common interests to protect and enable the core business.
Having a change management plan with dedicated resource support is vital to develop an open mind across various levels of management, professionals, and field staff. Senior leadership support to foster collaborative culture and share joint responsibility can accelerate the change. A governance committee group can help enforce the joint responsibility even if two teams are not combined organizationally.
50%: Percentage of 39 North American utilities that have concrete plans for IT/OT convergence, according to a poll conducted by McDonnell Group, on behalf of Ventyx (TCS, 2016).
46%: Percentage of surveyed utilities that have dedicated change management staff, compared to 76% of overall respondents (Prosci, 2016).
"People are the most difficult challenge to overcome where process and technology can be sorted out. Having the right mindset and attitude is to embrace new technology and adapt to new processes."

Readiness checklist to start building your talent pool
Like the implementation of any modernization technologies and application, the cost, time, and effort required to develop the right talent are substantial.
Utilities are often surprised by the level of gaps during projects and find themselves scrambling to shuffle to make do with already lean teams. The following checklist is to help you be better prepared for the journey.
Build a competency-based talent development plan
- Collaborate between IT and OT managers, HR, and union if applicable to conduct a needs/competency review against the future technology team.
- Develop succession plans at all levels, including professionals and field staff, to prepare for the employee turnover due to aging workforce and competitive market.
Develop a change management plan
- Secure sponsorship from the senior leadership team to engage employees at all levels for this plan.
- Set up a governance structure to foster a joint accountability and promote across-functional collaboration.
Diversify talent development plan
- Leverage expertise from vendor and system integrator as a professional development opportunity for staff.
- Offer versatile training methods for different types of learners to ensure operational consistency and safety.
- Diversify sources of talent recruitment and development. For example, provide cross-training opportunities for both IT and OT teams. Support recruitment diversity, equity, and inclusion.
Increase adoptions of cross-discipline processes
The growing similarities between the underlying technologies increases the adoption of IT operational processes to OT operations. Rankings of priorities among availability, integrity, confidentiality, and safety are still different between IT and OT systems in utilities. However, OT teams and IT teams can both benefit from enforcing some of the well-established cross-discipline processes.
Standardization
To increase supportability and reliability, standardization of ICS ecosystem is important. Standard software, configuration, security, and even devices can help with reduced errors, faster deployment, and ease of maintenance. It also helps with compliance and interoperability and in reducing shadow IT/OT.
Lifecycle Management
Regular updates to install the latest available features improve reliability and stability. It can also avoid hidden cost to maintain obsolete and unsecured systems.
Plan for more frequent upgrades of various components within the modernized ecosystem.
Process Governance
Operation consistency is often overlooked at the risk of reliability. Identifying operation process owners with periodic reviews can improve operational efficiency. Operational data analytics can also reinforce processes consistency.
Info-Tech Insight
Once processes are well-established and consistently executed, certain operations could be automated, limiting the need for documented processes and reliance on experienced staff.
Elevate process optimization from the micro level to the macro level
Many organizations take the opportunity to review existing OT processes and identify areas for optimization on the micro-level, as part of the ICS modernization project.
Here are some examples of standardization:
- System-wide universal tagging standard and naming convention.
- Control panel parts, layouts, and field-wiring designs.
- Server and network equipment specifications.
- PLC hardware configuration and coding standards.
- HMI application standards with code templates.
- Alarm messages, screens, and procedures.
Sources: ISA, 2011; Control Engineering, 2021.
Modernization demands a process review on a broader macro level across the overall OT practices. Compared to IT, historically, OT lacks a standardized management and governance framework. Instead of reinventing the wheel, one approach is to leverage a comprehensive existing research of the core IT processes and adapt them into the OT practices.
Readiness checklist to start redesigning your core processes
Due to the interdependencies of systems and teams introduced by complex ICS technologies, siloed processes become detrimental to the effectiveness and efficiency of the grid operations. Process engineering must be iterative during and after the project implementation to reach its maturity level.
Assess process and accountability gap
- Conduct a maturity assessment of key processes and highlight gaps that are focusing on operation reliability and risk resilience.
- Document process RACI across key areas with the acknowledgement from IT, OT, and business stakeholders when it comes to data ownership and cybersecurity.
Improve key areas
- Investing in time and effort for a holistic master plan and design analysis will pay off and avoid costly mistakes or regrets.
- Develop ICS standards documents to guide how ICS/SCAD should be implemented, operated, and supported.
- Execute process integration by developing a shared vision among IT and OT security leaders to foster a culture of mutual understanding.
Adopt a macro-level approach
- Collaborate with cross-functional teams to remove operational silos and assess process improvement comprehensively.
- Adopt a journey mapping methodology to identify opportunities and measured metrics to gain efficiency.
- Define ongoing review cadence to ensure the maintenance of policies, procedures, and processes.
Modernization increases technology complexity and creates challenges
The basic operation of an ICS is well established, but the actual implementation can be very complex. Over the years, technology advancement helped reshape how automation is done within the utility industry. Along with new capabilities, the overall complexity of the system has grown with many added layers of equipment, protocols, and standards.
With more components to maintain in the ecosystem, the lifecycle cost of support also grows. On top of that, utility business portfolios change over time via mergers and acquisitions and so does the diversity of automation technologies. Security and interoperability are among the top challenges to overcome.

Broaden the use of ICS data into your data management layer to make better business decisions. For example, underground water pipes or electric cable replacement can be very costly. SCADA data such as hours of operations or number of operations paired with CMMS data can drive better insights into the failure rate of assets to assist in preventative and predictive maintenance programs.
Bad data leads to bad decisions. Advanced data analytics have made promising benefits across both IT and OT domains. Similarly, data quality remains a major challenge to overcome in the OT domain. ICS automation relies on quality data.
- Operation and compliance reporting such as daily energy usage and water quality report.
- Alerts and drill downs such as gas pressure, senor alarms, and potential root causes analysis.
- Statistical and trending analysis such as overhead line failure rate based on historical data and forecast of likely failure of line segments if current trends continue.
- Predictive and prescriptive analysis such as hydraulic modelling of water pressure levels and apply what-if alternative analysis to compare scenarios to recommend optimal actions.
- Integration and optimization analysis such as enterprise-wide utility operation risk dashboard to make data-driven decisions to safeguard its critical operations. Organizations can tap into ICS data for building a sustainable future.
