From Excel to Structured Professional OT Governance: A Realistic Starting Point

by Silvan Pfirrmann | 18.08.26

OT management is now one of the most important responsibilities in industrial production environments. Many companies still manage their OT data using Excel spreadsheets, network drives, and individual experiential knowledge. However, with increasing requirements from NIS2, IEC 62443, audits, and cybersecurity, structured OT management is becoming a prerequisite for transparency, compliance, and operational reliability.

For many industrial companies, OT management primarily means one thing: working with the resources already available.
Excel spreadsheets, folder structures, and experiential knowledge shape daily operations in production, maintenance, and automation.

The problem often does not become apparent immediately.
Only when systems fail, audits take place, IEC 62443 or NIS2 requirements must be implemented, or new sites need to be integrated does it become clear:

πŸ‘‰ The information exists, but it is not available in a structured manner.

With eguide4DATA, a difficult-to-control situation is transformed step by step into a transparent and manageable process. This enables companies to establish the foundation for professional OT management and sustainable OT governance.

❌ The Problem: Excel Instead of a System in OT Management

A typical real-world scenario:

An employee needs to check the current status of a PLC.
The information is spread across:

  • πŸ“„ Excel spreadsheets
  • πŸ—‚οΈ Network drives
  • πŸ’Ύ Local backups

πŸ‘‰ Result: It is unclear which version is the current one.

This scenario is encountered by many companies in their day-to-day OT management. The data exists, but it is stored

⚠️ The Consequences

  • ⏱️ Time lost searching for information
  • ⚑ Uncertainty during ongoing operations
  • 🚨 Increased risk in the event of failures

The more complex a production environment becomes, the greater the impact of these issues on operational reliability, availability, and efficiency.

🧩 The Real Cause

  • The problem is not missing data, but the lack of a reliable structure to make it centrally available, up to date, and traceable.
  • No central repository serving as a single source of truth.
  • No automated and up-to-date backups, which can result in the latest version being unavailable in an emergency.
  • No traceable changes and no version control.

πŸ‘‰ Structures often grow organically. They only become reliable when supported by a clearly defined system.

Modern OT management creates exactly this structure and ensures that plant information is always available, up to date, and fully traceable.

βœ… OT Management with eguide4DATA

eguide4DATA centralizes OT management and makes data immediately usable.

πŸ’Ύ Automated Backups

Backups run in regular cycles without manual intervention.

Benefit:
The current version is always secured and available.

For professional OT management, the continuous backup of engineering data, configurations, and controller versions is essential.

πŸ“Š Track Changes (Version Control)

All changes are documented:

  • with a timestamp
  • with user attribution
  • with IP address information

Benefit:
Transparency for operations, troubleshooting, and audits.

Through complete traceability, eguide4DATA supports audit-ready OT management and significantly simplifies compliance processes.

πŸ‘οΈ Monitoring of Systems and Data States

eguide4DATA enables continuous monitoring of systems and data states.

Benefit:
Deviations and risks become visible early, before they impact operations.

As a result, OT management evolves from a reactive task into a proactive process.

πŸ” Why eguide4DATA?

Unlike traditional IT backup solutions, eguide4DATA was specifically developed for industrial OT environments:

  • automatic data collection instead of manual maintenance
  • support for various manufacturers and file formats
  • centralized visibility across all systems and data states

πŸ‘‰ This creates a reliable and up-to-date data foundation for the first time without additional documentation effort.

🧩 Implementing OT Management Step by Step

eguide4DATA has a modular architecture and can be implemented exactly according to the requirements of each organization.

  • Start with selected modules such as Version Control or Backup & Imaging
  • Expand step by step as needed
  • Adapt to existing processes and systems

Benefit:
Investments remain predictable, risks stay low, and implementation takes place without disrupting existing systems.

πŸ‘‰ Organizations decide for themselves which functions they need and when, instead of introducing a complete system all at once.

Successful OT management often starts with a small number of critical assets and then grows alongside the organization's requirements.

πŸ›‘οΈ OT Management for Compliance and Resilience

Today, structured OT management is about more than operational reliability. It is a fundamental prerequisite for compliance, cybersecurity, and resilience.

With eguide4DATA, you create the foundation for:

  • traceability of changes
  • secure and up-to-date system versions
  • support for requirements such as NIS2 and IEC 62443
  • greater transparency across assets, projects, and data repositories

πŸ‘‰ Audit readiness is achieved automatically rather than through additional documentation efforts.

In addition, structured OT management helps organizations identify risks at an early stage and ensure the long-term secure operation of critical production systems.

🧭 Implementation: Building OT Management Step by Step

A realistic entry into professional OT management is possible regardless of industry, company size, or existing infrastructure.

The key is to start with the most critical assets and processes and then systematically expand OT management over time.

ο•‹

Step 1

Create an inventory and establish transparency.
The first step is to capture existing assets, controllers, engineering systems, and relevant data sources. The objective is to gain a complete overview of the existing automation landscape.

ο•‹

Step 2

Set up backups for critical systems.
The most important production systems are backed up automatically. This creates the foundation

ο•‹

Step 3

Define responsibilities and processes.

Clearly defined responsibilities ensure that changes can be documented and controlled in a traceable manner.

ο•‹

Step 4

Integrate additional systems, production lines, and sites.
OT management grows step by step and adapts to the organization's requirements.

ο‚€

Important

The implementation is intentionally pragmatic and does not require a disruptive system overhaul. Measurable improvements in transparency, security, and availability are often achieved within a short period of time.

βš™οΈ OT Management in Everyday Operations

Practical Example: Production Downtime

An unplanned production shutdown is one of the situations where the quality of OT management becomes immediately visible.

Previously:

  • πŸ” Time-consuming search for the latest available version
  • Uncertainty about the correct version
  • Inquiries across multiple departments
  • Significant loss of time during recovery

With eguide4DATA:

  • βœ… Latest approved version immediately available
  • Complete traceability of all changes
  • Automated backups available
  • πŸš€ Fast and reliable recovery

πŸ‘‰ Result: less downtime, greater control, and significantly faster restarts.

The tangible benefits of professional OT management become particularly evident in critical production processes.

πŸ“ˆ What Are the Benefits of Structured OT Management?

  • Greater transparency across assets and projects
  • Faster troubleshooting and root cause analysis
  • Reduced manual documentation effort
  • Improved audit readiness
  • Enhanced cyber resilience
  • Higher availability of critical systems
  • Support for NIS2 and IEC 62443 requirements

Structured OT management therefore creates the foundation for long-term secure and economically efficient production.

πŸ“Œ OT Management at a Glance

  • Excel is suitable for getting started, but not for maintaining stable OT processes over the long term.
  • Risks often arise from a lack of structure rather than from missing data.
  • OT management ensures transparency across assets, versions, and backups.
  • eguide4DATA enables a step-by-step implementation without requiring a large-scale project.
  • Modules can be expanded flexibly.
  • Initial results often become visible within just a few weeks.
  • Compliance requirements such as NIS2 and IEC 62443 can be supported more easily.
  • OT management becomes planned rather than improvised.

🧾 Conclusion

Structured OT management is not created through a large-scale project. It starts with a clear first step:

  • Create transparency and establish an overview
  • Protect critical systems
  • Define processes
  • Expand step by step

Organizations do not need to transform their entire infrastructure at once. In many cases, initial measures in inventory management, backup, and version control are already sufficient to significantly improve transparency.

eguide4DATA provides the foundation for this approach - modular, scalable, and specifically designed for industrial OT environments.

This transforms scattered information into structured OT management that creates transparency, reduces risks, and supports the long-term operation of critical production systems.
