Since we are given no information to the contrary, the following discussion assumes that all men are created equal, and every worker accomplishes the same amount of work in the same amount of time. Since 8 workers can build a cabin in 60 hours, the job comprises (8 man) times (60 hours) = 480 man-hours of labor. That doesn't change. Now however, 480 man-hours of labor must be completed in 32 hours. The number of workers required to accomplish this is (480 man-hours) divided by (32 hours) = 15 man.

What is limited functionality simulation?
More functionality must be built into the prototype to demonstrate the work that the application will accomplish. Storyboards and animation techniques are not sufficient for this purpose, as they cannot portray adequately the interactive aspect of the system. To do this, some portion of the functionality must be simulated by the design team. Programming support for simulation means designer can rapidly build graphical and textual interaction objects and attach some behaviour to those objects, which mimics the system's functionality. Once this simulation is built, it can be evaluated and changed rapidly to reflect the results of the evaluation study with various users.
