  • Product Semantic Analysis (PSA) Become our friend to view this Tool/Method
    The methods involves several steps:
    -interviews with consumers and producers/designers to identify relevant words (adjectives) for the product domain (Note: specific for each product/product area);
    -reduction of adjectives and construction of semantic scale and instrument including preferred and non-preferred expressions. A visual, analogue scale is recommended for increased sensitivity. The scale is anchored in two points...
  • SUMI Become our friend to view this Tool/Method
    The SUMI is a 50 items Likert-type questionnaire. Users of a product should indicate their agreement with 50 statements such as “I enjoy my sessions with this software.” or “It takes too long to learn the software commands.” using a three- point format (“agree”, “don’t know” and “disagree”). Each subscale is represented by 10 items. The “affect” subscale is supposed to measure “the user’s general emotional...

    This online tool allows:
    - Carrying out the emotional assessment of products on the basis of users’ visual perception of stimuli and expressed through semantic differential scales.
    - Making calls for test persons of particular characteristics
    - Keeping track of results in real-time
    - Providing a reward to test subjects
    - Automating conditional questions
    - Randomising the presentation of stimuli...
  • Repertory Grid Technique (RGT) Become our friend to view this Tool/Method
    First, an individual participating in an elicitation session produces his or her own constructs, i.e. what bipolar dimensions of meaning the person see as the most important ones for talking about the elements (the investigated phenomena). The construct elicitation process is typically eased by the use of triads, where the subject becomes exposed to sets of three elements at a time and is asked to describe and put a label on what he or she...
  • Scenarios Become our friend to view this Tool/Method
    Scenarios are short stories of envisioned real life situations that describe a specific user group in a specific contextual setting interacting with specific devices to fulfil specific tasks and intentions. It
    illustrates the usage, the functionality and purpose of novel devices and services in daily life. An important aspect is that the scenario presents a context of use that can help to emphasise variables not apparent from a more...
  • A new adaptive Conjoint Analysis Become our friend to view this Tool/Method
    It is assumed that the product/service can be decomposed in several improvable elements and/or enriched with new “optional”. In both cases, what under study is a set of dichotomous attributes. For each of these attributes, its marginal contribution to some utility measure (e.g.customer satisfaction) needs to be modelled and estimated.
    To obtain this information, an opportune questionnaire is administered to a sample of respondents....
  • Attribute rating using choice time Become our friend to view this Tool/Method
    The methods for measuring the relative importance of product attributes can be classified broadly as direct questioning and indirect questioning. In the former, a
    respondent is asked to directly rate or rank the attributes. In the latter, a respondent is not directly asked which attribute is important. The new proposed procedure indirectly captures customer opinion on attribute by using the choice time (indirect questioning) during the...
