1. A single page website, emblematic of a larger product. Landing pages are occasionally used to scaffold prototypes or mockups for the sake of providing the user with extra context, or to test value propositions before building a product.

2. unique selling proposition - the main reason why a user chooses one product over another.

3. minimum viable product - A core component of Lean, an MVP is a stripped down version of a product launched quickly in order to gather user feedback earlier in the product lifecycle. Large companies are beginning to use 'MVEs' instead of MVPs.

4. a simulation of functionality or design meant to put testers in the proper mindset to answer questions through behavior rather than self-reporting. Prototypes are the means by which experiments generate actionable data and provide a framework by which product managers can evaluate and benchmark new product features iteratively. Many tools have been developed to make prototyping accessible to product managers.

5. Voice of the customer is a market research technique that produces a detailed set of customer wants and needs, organized into a hierarchical structure, and then prioritized in terms of relative importance and satisfaction with current alternatives.

6. Data derived from behavior reflects unconscious or unintentional biases that may be excluded when a tester is asked to self-report their experience using a mockup, prototype or product.

7. coined by Clayton Christensen, disruption refers to an innovation that gives new consumers access to product historically only available to consumers with a lot of money or skill often with a new business model.

8. how likely user is to recommend the product to a friend. This is considered to be a good indication of how valuable they find the product.

9. A survey pattern used against large, roughly equal groups of cohorts that measures perception of value of two slightly different concepts.

10. Typically done just prior to launch, to improve the quality of the product, integrate customer input on the complete product, and ensure launch readiness.

11. A tactic used to quickly gather user insights. Surveys, landing page split tests, and interviews are examples of experiments.

12. short for value proposition, this term describes the user's primary motivation for using the product or the main benefit they receive from it.

13. a qualitative data gathering session that makes use of live interaction to follow-up on outlying responses and paint a fuller picture of the user's experience using the product. Check out Mind The Product for some great user testing tools.

14. the user's entire experience from initiating the mockup, prototype, or product to closing it and returning to their life.

15. a different version of a product or design, developed in order to see what will receive the best response from customers.

16. A group of people who fit a specific user criteria, used for surveys, interviews, and prototype testing.

17. an organization that helps startups and entrepreneurs to grow by providing services such as training and office space.

18. a user test with no interaction between the test team and the user. Results in video clips of the user's screen, audio recording of the user's voice, and is often tabulated with other user tests to generate quantitative insights.

19. Typically started within a large company, an innovation lab is a small team of employees tasked with building new products and businesses.

20. Get out of the building - Coined by Steve Blank to refer to the process of going out and talking to users instead of staying inside speculating about what they want.

21. a tool used in Agile environments to capture a description of a software feature from an end-user perspective. The user story describes the type of user, what they want and why. They typically follow a simple template: As a , I want so that .

22. the critical aspect of the experiment the user must view in order to measure reaction. If the stimulus or test criteria is buried too deep within the mockup or is too hard to find, the user may not know what they are supposed to be reacting to.

23. user experience - how a user feels when interfacing with a product. UX designers study and evaluate how users feels by looking at such things as ease of use, perception of the value of the system, utility, and efficiency in performing tasks. Check out uxisnotui.com for a direct comparison of the two.

24. user interface - the visual dimension of any given product or service, as the user connects to it. UI designers determine how information and features are laid out visually within the greater product.

25. People use pivot in so many different contexts I don't think anyone really knows what it is anymore. It originally referred to a small change in a company's business model or product in order to meet customer needs, but now often refers to starting a new product all together.
