User Productivity Kit is a simulation production and publishing tool from Oracle, which recently purchased the company that developed UPK, Global Knowledge. After you record a transaction in your target software application, you can generate four different playback modes (non-interactive See It! mode, interactive Try It! mode, interactive-with-scoring Know It? mode, and interactive context-sensitive-help Do It! mode). A fifth mode, Print It!, lets you decide whether to include a link to a printed version of the simulation.
