DoE makes tests more meaningful, reduces unnecessary loops and connects testing with robust statistical evaluation.
RelTest plans, supports and evaluates DoE studies around the technical question. Statistics and product understanding are combined so that experimental points lead to a usable engineering decision.
What we work on
We clarify responses and evaluation criteria, identify relevant control and noise factors and define technically meaningful levels and design-space limits.
What you receive
A clearly documented experimental question with responses, factors, constraints and assumptions.
What we work on
We select an appropriate design, plan randomisation, replication and blocking, and align the experimental sequence, measurement system and data quality.
What you receive
An efficient, executable DoE plan with a clear design matrix and controlled workflow.
What we work on
Effects and interactions are estimated, models are checked, and results are evaluated together with residuals, model fit and technical plausibility.
What you receive
A traceable response model showing which factors act on the response, how strongly and in which combinations.
What we work on
We optimise responses, assess sensitivities and noise factors and translate findings into parameter recommendations, further tests or engineering measures.
What you receive
Recommended settings with a robustness assessment, documented limits and a clear next step.
DoE creates the greatest value when test capacity is scarce and several influences need to be understood together.
Every run consumes samples, test-bench capacity and development time. A justified design focuses effort on highly informative experimental points.
Screening and suitable designs reveal which factors matter and where interactions make one-factor-at-a-time testing misleading.
Products and processes must perform beyond the mean. DoE helps identify parameter regions that remain robust to manufacturing, environment and use.
This Solutions page brings together project support. Method foundations belong in Knowledge; structured capability building belongs to RelTest Education.
We clarify the technical question, available test framework and the DoE approach that can deliver the required evidence with reasonable effort.
