Proof of Principle: The Key to Reducing Risk in Bespoke Automation

February 2025

In the world of bespoke automation, where every project presents unique challenges, the key to success lies in careful planning and risk mitigation. One of the most effective ways to reduce uncertainty is through proof-of-principle (PoP) validation, a process that tests critical design elements before committing to full-scale production.

At SP Automation & Robotics, PoP is an essential step in our development process. By validating core functionalities early, we ensure that our automation solutions meet performance expectations, integrate seamlessly into operations, and avoid costly late-stage modifications.

What is Proof of Principle?

Proof of Principle (PoP) refers to a preliminary test or prototype that demonstrates whether a specific function, technology, or design concept will work as intended. It is not a full prototype of the entire system but a targeted test of the most critical or high-risk elements of the design.

For example, if an automation system requires a custom gripper to handle fragile materials, we may conduct a PoP test to determine whether the gripper design provides the necessary precision and control. Similarly, if the project involves a new robotic vision system, we may run a PoP to confirm its accuracy in detecting and identifying objects before integrating it into a full production line.

By isolating and testing these key aspects, PoP helps us identify potential issues early—long before they become costly challenges in later stages of development.

Why Proof of Principle is Critical in Risk Mitigation

Automation projects inherently carry technical, operational, and financial risks. Without early testing, a project could encounter unexpected challenges after significant investments have already been made. PoP validation helps mitigate these risks in several key ways:

Identifying and Eliminating Technical Risks

Many automation systems rely on new or unproven technologies. A PoP study allows us to assess:

• Whether the selected components will function as expected in real-world conditions.
• How different subsystems interact and whether they introduce any unforeseen complications.
• Whether a concept needs to be adjusted before committing to full-scale development.

By conducting PoP trials early, we can refine the design and prevent failures before they occur, ensuring a more robust and reliable solution.

Preventing Costly Late-Stage Modifications

One of the biggest risks in automation development is investing significant time and resources into a design, only to discover late in the process that a fundamental element does not work. Late-stage modifications can be expensive and cause project delays.

PoP helps prevent this by allowing us to test and refine critical aspects before committing to full production. If adjustments are needed, they can be made in a controlled, low-cost environment—saving time, money, and effort.

Enhancing Project Predictability and Timelines

Automation projects often operate on tight schedules. Unexpected issues can lead to delays, downtime, and missed deadlines. By conducting PoP validation early, we reduce uncertainty and create a more predictable development timeline.

Knowing that key elements have already been validated gives our clients greater confidence in the project’s progress and reduces the likelihood of unforeseen setbacks later in the process.

Improving System Performance and Reliability

A well-designed automation system must not only function correctly but also perform efficiently and reliably in real-world conditions. PoP testing allows us to fine-tune system performance, ensuring that:

• Motion sequences are optimised for speed and precision.
• Sensors and control systems respond accurately under different conditions.
• The system meets or exceeds the required performance criteria.

By making these adjustments early, we ensure the final system operates smoothly and delivers long-term reliability.

Ensuring Seamless Integration with Existing Systems

Many automation projects require new systems to integrate with existing production lines, software, or operational workflows. A PoP study can assess whether these integrations will function as expected and highlight any necessary modifications before full implementation.

This prevents potential compatibility issues, downtime, or disruptions when the system is deployed, ensuring a smoother transition from development to production.

POP and Pilot Systems

In certain cases, SP’S clients require pilot lines, which serve as an advanced stage of the Proof of Principle (POP) process. By leveraging insights gained from POPs, smaller, scalable systems can be designed to facilitate the development of full-scale manufacturing systems. The data collected during this process is invaluable, enabling simultaneous product development alongside the design and refinement of manufacturing systems.
