The combined use of InVision and Sketch has changed the way some people approach web application development. Although these are tools, it is really the technique of prototyping with InVision and Sketch that makes this blip significant. Creating rich, clickable prototypes as the starting point for implementing front-end and back-end behavior helps speed up the development and eliminates churn in the implementation details. This combined use of these tools strikes the right balance between premature elaboration of visual detail and capturing early user feedback on the interactive experience.
