a technique used in qualitative research, involving observation of respondent behavior in specific setting (home, store, work).
Here a research becomes a participant of what is going on, enters the respondent's social circle, is witness to researched actions, updating and explaining his/her observations.
Observation is used chiefly in behavioral studies, especially of actions done "automatically", which are difficult to verbalize.
Examples might be shopping (at sale outlets), hoe chores (cooking, cleaning), observation of children.

a draft version of a TV commercial, with a sequence of schematic stills/ frames.
The stills/frames are usually accompanied by the soundtrack planned for the final execution - music, background noises, VOA.
Animatics are used in early stages of advertising copy tests. Avoiding the expense needed for full execution, it is possible to test consumer reactions to the idea behind the communication, identifying generated associations, measuring persuasion, or main weaknesses to eliminate.

a questionnaire filled out in a hall/ auditorium, where all the project's respondents were gathered.
The respondents, after being handed out the questionnaires, complete them on their own, usually with the possibility of asking researchers present on site for clarification.

(English - Brand-Price Trade-Off) a quantitative technique used to measure the price flexibility of mass produced goods.
BPTO is an experimental study, in which the respondents make a series of choices from a set of products of the same category (E.g. competing brands of alcohol, sweets, cosmetics, etc).
During the test the prices of the products are changed dynamically, in light of the respondent's choice.
Hence the respondents have to make multiple choices, trading off the of price versus their subjective valuation of the presented brands.
Advanced statistical analysis of such data allows for anticipating various demand scenarios - levels of interest in brands at different price levels.
BPTO helps in making the final decision as to pricing strategies for selected brands, by pointing out the possible effects of price wars.
