Abstract
The success of IT project depends deeply on the capability and the available number of staff. Therefore, in order to keep to schedules and to assure quality of products, it is required to re-evaluate the excess and deficiency of assigned man-hours periodically until the delivery date or the mile stone point and also to secure additional staff promptly if insufficient. Periodical evaluation is particularly effective in taking a prompt action when an extra work besides original estimation or a delayed work which should be coped with at the time occurs. "The control technique of remaining man-hour requirements" is the technique that controls a project by grasping subsequent (remaining) man-hour requirements at each estimation point. This technique uses the value conversion technique equivalent to EVA (Earned Value Analysis), which is based on an originally estimated value (man-hours).
