Design-Expert 13 gives you the latest technology to analyze multifactorial data and design experiments in a very user-friendly environment. Design experts guide you through the classic stages of refinement, optimization (RSM), and validation while providing the flexibility to map complex tasks in a test design “simple”. As a result, Expert Designers allow you to save time and money on new product development while achieving the best process conditions.

• Response Surface Method (RSM): Find the optimal process settings for peak performance.

• Rotatable 3D graphics, interactive contour (contour) graphs, best ternary representation,

• All classical experimental designs, d-optimal for screening and i-optimal for RSM,

• Latest batching designs and definitive screening designs,

• The best optimization function (multiple target variables and optimization related to factor settings),

• Fitted function exported as formula to Excel

• Error propagation (error propagation) helps you find powerful settings

• Mixed Design Engineering: Discover the ideal formula for your product formulation.

• Combination of process factors, mix ingredients and grading factors: Mix your cake (with different ingredients) and bake it!

• Design and analyze split plots: Make your testing much easier by grouping hard-to-change process elements and/or mixed components.

• Your Design-Expert program provides rotatable 3D tiles to easily view the response surfaces from any angle. Use YOUR MOUSE to set flags and explore contours on interactive 2D graphs. Our numerical optimization function finds the maximum desirability for dozens of simultaneous responses!

Hard-to-change factors handled via split plots

• Two-level, general and optimal factorial split-plot designs: Make it far easier as a practical matter to experiment when some factors cannot be easily randomized.
• Half-normal selection of effects from split-plot experiments with test matrices that are balanced and orthogonal: The vital effects, both whole-plot (created for the hard-to-change factors) and sub-plot (factors that can be run in random order), become apparent at a glance!
• Power calculated for split plots versus the alternative of complete randomization: See how accommodation of hard-to-change factors degrades the ability to detect certain effects.

Other new design capabilities

• Definitive screening designs: If you want to cull out the vital few from many numeric process factors, this fractional three-level DOE choice resolves main effects clear of any two-factor interactions and squared terms (see screen shot of correlation matrix – more on that later).
• On the Factorial tab select a simple-sample design for mean-model only: Take advantage of powerful features in Design-Expert software for data characterization, diagnostics and graphics – for example with raw outputs from a process being run at steady-state.

Much-improved capabilities to confirm or verify model predictions

• Entry fields for confirmation data and calculation of mean results: Makes it really easy to see if follow-up runs fall within the sample-size-adjusted prediction intervals.
• Enter verification runs embedded within blocks as controls or appended to your completed design: Lend veracity to your ultimate model by these internal checks.
• Verification points displayed on model graphs and raw residual diagnostics: See how closely these agree to what’s predicted by your model.

New and more-informative graphics

• Adjustably-tuned LOESS fit line for Graph Columns: Draw a curve through a non-linear set of points as you see fit. *(Locally weighted scatterplot smoothing.)
• Color-coded correlation grid for graph columns: Identify at a glance any factors that are not controlled independently of each other, that is, orthogonally; also useful for seeing how one response correlates to another.

Greater flexibility in data display and export

• Journal feature to export data directly to Microsoft Word or Powerpoint: Fast and formatted for you to quickly generate a presentable report on your experimental results.
• Improved copy/paste of Final Equation from the analysis of variance (ANOVA) report to Microsoft Excel: This not only saves tedious transcription of coefficients but it also sets up a calculator for you to ‘plug and chug’, that is, enter into the spreadsheet cells what values for the inputs you’d like to evaluate and see what the model predicts for your response.
• New XML* script commands for exporting point predictions: Helpful for situations where one wants to automate the transfer of vital outputs from Design-Expert to other programs. *(Extensible Markup Language)

More powerful tools for modeling

• All-hierarchical model (AHM) selection: Sort through all possible models up to the one you designed the experiment for, but all the while maintain hierarchy of terms so you do not end up with something ill-formulated.
• Special quartic Scheffé polynomial included in automatic selection for mixture modeling: Sometimes this added degree (4th!) of non-linear blending helps to better shape the response surface – making it better for predictive purposes.

More choices when custom-designing your experiment

• Enter a single factor constraint for response surface designs: Creates a ‘hard’ limit on inputs that cannot go beyond a certain point (such as zero time) physically or operationally.

More capability for numerical optimization

• Include Cpk* as a goal: Meet quality goals explicitly. *(A process capability index widely used for Six Sigma and Design for Six Sigma programs.)

Enhanced design evaluation

• One-sided option added to FDS* graph: Size your design properly for a verification experiment done to create a QBD** design space. *(Fraction of design space) **(Quality by Design – a protocol promoted by the US Food & Drug Administration (FDA).)

Many things made nicer, easier, more configurable and faster

• Diagnostics report now can be sorted by any of the statistics listed: This enables a more informative ordering than by run number (the default).

Niceties that only statisticians might truly appreciate

• Mean correction for transformation bias when responses displayed in original scale: All you need to know is that our statisticians figured out how to eliminate a tricky, little-known bias!
• Propagation of error (POE) carried out to the second derivative: Makes POE more accurate – that’s a good thing!
• Allow averaging of categoric factors when viewing a graph: Convenient for getting the big picture of where to find robust operating settings.
• Display confidence bands with or without POE added: Easier to match output with other programs that do not offer POE features like this.
• Add unblocked results to evaluation of blocked experiments: Aids in comparing designs on the basis of matrix measures.

Good news for network administrators

• >New more flexible and easier-to-use license manager with greater power to serve enterprise users: For example, network ‘seats’ can be checked out to individual laptops and multiple opening of the program on a specific computer will only use one seat.
