Announcement of release

December 1996

Dear Experimenter:

Stat-Ease announces version 5 of DESIGN-EXPERT software to optimize your product or process. This Windows-compatible software provides highly-efficient design of experiments (DOE) with which you can:

• Screen the vital factors that affect your process or product. Make a breakthrough with two-level full or fractional designs!
• Find the ideal process settings so you can achieve optimal performance. Optimize your process via response surface methods (RSM).
• Discover the best recipe for your formulation. Hit the sweet spot with mixture design techniques.
• Use graphs to interpret your results. DESIGN-EXPERT for Windows offers rotatable 3D plots for visualization of response surfaces. Interactive 2D graphics allow users to explore the contours with their mouse, clicking to set flags that display coordinates and predicted responses.
• Optimize your process. Power users will appreciate the numerical optimization function, which finds maximum desirability for up to 12 responses simultaneously

"The rotation for the 3D surface is great!!! You have a winner."
- Ken Chatto, DESIGN-EXPERT software tester

The new Windows version offers powerful enhancements including:

• All features that were previously only available in DESIGN-EASE software
• Unique push-button interface that makes it incredibly easy to do DOE
• A "fixed pane" Windows display keeps things simple for you--no clutter
• Many more new features for ease-of-use and statistical power (see listing).

You'll find it a joy to work with DESIGN-EXPERT Version 5 software for Windows. It makes DOE easy. You can't afford not to take advantage of these powerful techniques for process and product improvement.  Give it a try at no obligation for 30 days!

Comments from users of DESIGN-EXPERT version 5 software
"I love it! Just point and shoot!" - Pete Runke, Eastman-Kodak, Rochester, NY
"Most-user friendly statistical/DOE package on the market. Believe me, I've tried them all. This makes problem-solving fun!" - John W. Owens, III, Sheldahl Inc., Northfield, MN
"I am very excited about the combination of DESIGN-EASE and DESIGN-EXPERT into Windows. It has a great overall look and feel." - Patrick S., DOE Trainer, Austin, TX
"It's a fantastic tool. Setup and analysis can be done in minutes." - Shari Kraber, Frigidaire, St. Cloud, MN
"Graphics very impressive. I really like the projection of the 3D contour." - J.D. Guerin, Turning Point Management, Consultants., Gladwyne, PA
"I like the sliding control for the level of factors on the 2D contour plots." - Ken Chatto, DOE trainer, Lugoff, SC
"Great big kudos for your new irregular fraction for two-level design! We did 7 factors in 48 runs. It went extremely well." - James Walck, Osram-Sylvania, Towanda, PA

Summary of what's new in Design-Expert

New Features in DESIGN-EXPERT version 5 for Windows:

• New interface
• Cut and paste graphics to word processors
• Cut and paste numbers from/to spreadsheets
• Single window default with pop-out option
• Icon buttons to lead you through analysis steps
• Checklist menu for ease of navigation
• Multiple reports and graphs can be open at one time
• Automatic update of all open windows when data is changed

DESIGN-EASE software integrated into DESIGN-EXPERT version 5:

• Simple comparative DOE's (one factor)
• Two-level full or fractional factorials

Improved graphics:

• "Drag-able" 2D contours
• Slide bar slicing for contour plot
• Actual design points shown if on slice
• Shading of poorly predicted regions (high Standard Error)
• Real-time 3D graphics rotation
• 2D contour projected from 3D plots
• Editable colors, text, etc. for snappy reports

New optimization capabilities:

• Create robust design via variance transmission
• Include factors in the criteria
• Rank responses by importance

New things you can do with factorials:

• Create 3/4 fractional 2-level factorial designs
• See alias structure for Plackett-Burman or any other odd or botched designs
• Have half-normal default for effects plot
• Have significant factors preselected on plot
• Use contour plots for factorial models
• View inverse transformation of responses
• Perform multiple response optimization

New things you can do with mixtures:

• Use slack variable models for analysis
• View models in terms of actual values
• Combine components

New D-optimal features:

• Can now put constraints on RSM designs
• Import or export candidate sets

Design repair and augmentation:

• Build up factorials to CCD
• Augment any design to fit a higher model

More measures for design evaluation:

• Pearson's correlation on factors
• Average and maximum prediction variance
• Scaled d-optimal measure

Other statistical enhancements:

• X vs. Y scatter plots to visualize data
• Maximum design points increased to 8000
• Retooled, more robust analytical engine
• Measure of adequate precision in ANOVA
