Function Allocation. Function allocation (also known as task allocation) is a classic human factors method for deciding whether a particular function will be accomplished by a person, technology (hardware or software) or some mix of person and technology.
perpendicular - a straight line at right angles to another line straight line - a line traced by a point traveling in a constant direction; a line of zero curvature; the shortest distance between two points is a straight line 2. perpendicular - a Gothic style in 14th and 15th century England; characterized by vertical lines and a four-centered (Tudor) arch and fan vaulting
From Latin: perpendicularis vertical, as a plumb line. A line is perpendicular to another if it meets or crosses it at right angles (90Â°). Try this Drag the orange dot at point A. The line AB will be perpendicular to DF only when it meets it at 90Â°. Perpendicular means at right angles.A line meeting another at a right angle, or 90Â° is said to be perpendicular to it. In the figure above, the line AB is perpendicular to the line DF.rom Latin: perpendicularis vertical, as a plumb line.
