Stage 1 | Exploratory

Stay mission-driven with exploration

There are many possible routes to improve a project's starting point for a given objective - new materials, new device designs, new fabrication methods, new tool designs, and more. The key is choosing the right directions to explore first.

Exploration Prioritization Guidance

1) Describe the potential mission impact clearly.
Explain what new capability or performance window the direction could open relative to the project objective, and use the Pathfinder framework to assess mission relevance.

2) Prioritize by quantitative value.
Evaluate timeline and expected impact in MOIs (Quality, Speed, Scale, OpEx, CapEx) and expected impact on device functionality.

Stage 2 | Reproducibility

Identify identical factor value sets

No parameter data loaded.
Group Matching factors Group subjects Objective MOI Valid n Mean Sample sigma CV (%) Range Target evaluation

Variation analysis
Process control verification to confirm stable output and repeatability before screening.

Reproducibility Setup

Percent variability lines are shown in the plot together with sigma lines.

If your file has the same column names for MOIs and PMPs as specified here, it will locate them and import automatically.
MOI (mean) values from all n Subject IDs
MOI2 values from all n Subject IDs
Enter or load values, then click 'Plot Reproducibility'.
MOI vs PMP linear correlations
Correlation coefficient (r) describes the strength and direction of the linear relationship between MOI and PMP, from -1 to +1.
P-value (p) measures evidence against no linear correlation; a smaller p-value indicates stronger evidence of a relationship.
Add PMP values and click 'Plot results' to calculate correlations.
Variability troubleshooting

Understand the Sources of Variability

Run-to-run variability can arise from several sources. Here are some suggestions to consider:

  • Equipment drift (e.g., temperature fluctuations, calibration shifts). Check PMPs.
  • Material batch differences? (e.g., substrate properties, chemical purity)
  • Operator differences (e.g., manual handling, setup inconsistencies). Automize and standardize.
  • Environmental factors (e.g., humidity, vibrations, electromagnetic interference). Log these as PMPs.
  • Measurement noise (e.g., instrument precision, readout errors)
Assess existing screening data

Experiment Setup
Set PCP count and names before suggesting DOE.
Process Control Parameters (PCPs)
Click 'Set PCP Count' to generate PCP name, low, high, and units fields.
After experiments
Generate DOE first, then enter MOI Mean (and optional Spread) for each Subject ID.

MOI2 effect ranking

Transfer key factors to Stage 4

Stage 4 | Optimization

After identifying the most critical PCPs with the largest effect on the MOI in Stage 3, optimize the MOI using Response Surface Methodology (RSM) with a quadratic model. Use Central Composite Design (CCD) to capture the true optimum efficiently.

Use Stage 3 effect ranking to choose key PCPs, then set low/high levels for CCD planning (center is the midpoint).

Typical CCD Subject ID count: 2^k + 2*k + center points, where k is the number of key PCPs. Enter the shortlisted key PCPs and their low/high optimization bounds below.

Optimization Setup
CSV/TSV/XLSX: one DP per row; first column is its name, remaining columns are numeric levels (optional header: DP, Level 1, ...).
Optimization factors
Click 'Set key PCP count' to generate optimization factor name, low, high, and units fields.

Generate the fixed RSM/CCD optimization matrix, including factorial, axial, and center-point runs.

After executing the basic optimization DOE add adaptive axial points here for finetuning optimum.

After experiments

Generate suggested Fixed RSM (CCD) Subject IDs first. Then enter MOI mean for each Subject ID.
