Design of Experiments (DoE)
Definition
Design of Experiments (DoE) is a systematic method for planning, conducting, and analysing experiments. Its goal is to evaluate the influence of multiple variables simultaneously and generate reliable insights with a minimal number of experiments.
Extended Explanation
In research and development, experiments are frequently used to optimise material properties, process parameters or formulations. Traditional approaches are often based on isolated experiments or trial-and-error methods, making relationships between influencing factors difficult to identify and requiring a large number of tests. Design of Experiments (DoE) follows a structured approach in which multiple influencing factors are varied simultaneously, allowing interactions between parameters to become visible. This makes it possible to statistically analyse cause-and-effect relationships and design experimental series more efficiently. DoE plays an especially important role in material-intensive industries, where material properties are often influenced by complex interactions between raw materials, process conditions and environmental factors. Typical applications include formulation optimisation, the investigation of process parameters and the improvement of product and material properties.
As digitalisation progresses, DoE is becoming increasingly important in combination with structured data capture, laboratory data integration and centralised data platforms. This enables experimental data to be used across systems and analysed over the long term, creating the foundation for data-driven development processes, predictive AI and approaches such as Material Intelligence.
Key Aspects of Design of Experiments
DoE combines structured experimental planning with statistical analysis to better understand complex relationships between parameters and results.A key aspect is the simultaneous variation of multiple influencing factors. This makes it possible to identify interactions that often remain hidden in traditional one-factor-at-a-time experiments. At the same time, the number of required experiments can be reduced while still generating reliable and meaningful results. With the growing availability of structured experimental data, DoE is increasingly evolving from an isolated experimental method into a continuous, data-driven optimisation process. In combination with AI-supported analytics and digital laboratory environments, existing models can be expanded, patterns identified and new experimental approaches derived.
Relevance to LabV
LabV supports Design of Experiments by combining experiment planning, data capture, and analysis within a central platform. By structuring parameters, formulations, and results, LabV creates a consistent data foundation for evaluation. Combined with AI-powered analytics, LabV can identify patterns, extend models, and suggest new experimental approaches. This transforms DoE from a one-time experimental setup into a continuous, data-driven optimisation process in R&D.
DoE generates structured, high-value data. But only if that data is captured and linked systematically across experiments. The LabV platform supports DoE-driven development by connecting experimental parameters, material properties, and test results in one place. To support your DoE workflows with LabV, book a demo.
