Hands on Consumer Driven Product Optimization, PARIS 10-12 OCT. 2018
Day 1 Exploratory and Modelling methods for Consumer Research
Designed to take you through the key methods that we use in consumer science and explain how they work and how they are applied to consumer data. Emphasis is given to the practical decision making that is made after each analysis. Participants will apply the methods to real life data using XLSTAT routines and will be guided by the written solutions that are a unique feature of Hal MacFie Training. These solutions give you the possibility to pick up the notes after 6 months or a year and remind yourself how a technique works and then apply it to your own data.
Deliverables: Analysis of variance one two and three way applied to sensory and consumer data. Theory, application and analysis experience in Principal Components (with rotation), Correspondence Analysis, Quadratic regression and inspection of response surfaces and the XLSTAT PREFMAP module applied to a single liking variable.
Day 2 Segmentation, Mapping and Portfolio optimisation
Segmentation Masterclass: This will give attendees a unique perspective: understanding and experience with the three main segmentation algorithms. Practical guidance onselecting the correct algorithm for the task, selecting the optimum cluster set, testing for stability will be given.
The key question with clusters is to identify any predominant characteristics of the membership ability and we will show a variety of approaches for this.
Deliverables: AHC, KMEANS and Latent Class Segmentation. Cluster Diagnostics and stability testing. Demographic and Psychographic analyses
Preference Mapping: The workings of the XLSTAT Preference Mapping module will be described, and its application to overall means, segment means and individual scores demonstrated. Product prototype selection and reverse regression to predict the sensory properties of a prototype will be followed by a new section exploring how to integrate the open- ended question responses into the decision making process.. In some categories Preference Mapping on consumer measures are gradually replacing sensory panel scores and a short section will exemplify this approach. Finally an assessment of the role and validity of internal, external and probabilistic models in this application will be discussed
Deliverables: External Preference mapping, Reverse Regression, Using open ended comments, Optimising product portfolios across segments and markets. Comparing internal and external models.
Day 3 What can you do with 3 samples or less?
This section is designed for the very important class of trials that collect CLT or Home Use test on 1 to 3 samples. Preference mapping models are not possible with these trials but there are many techniques that are well suited to product optimisation and can be applied to a single product trial.
Deliverables:Penalty analysis, Ideal Point Profiling, Kano Analysis using CATA data
Concept optimisation and Product matching. Many concept trials ask multiple questions including sensory about one or more concepts. How can we examine segmentation in the response to a single concept? Which concepts do we select for further development?
Deliverables: Factor Analysis and Segmentation on question batteries.
Typically consumer scientists are asked to supply a product that not only matches sensory expectations but enhances the emotional response and reinforces the Brand. We describe PLS on Fit to Concept measures and the use of Multiple Factor Analysis to handle sensory expectation trials. Brand conceptualisations including sensory, emotion and function can be investigated using CATA and Best-worst measures. MAXDIFF scales for prototypes and concept enable the best matching product to be selected.
Deliverables: Partial least Squares, Fit to Concept, Sensory expectation trials, Multiple factor Analysis, Best-Worst, MAXDIFF scales, Concept to product matching.
