Abstract
ISO21500 was published on September 1^<st> 2012. This is the first international standard regarding Project Management. It was established at PC236 which is one of the committees in ISO, and TC258 took over it as a maintenance role. TC258 is one of the committees in ISO as well. Its scope is wider than PC236 and it can provide multiple standards. New scheme has been accelerating the discussion on the standardization of Project Management area. Standard for Portfolio Management has been developing and already has the ISO number, ISO21502. Furthermore two groups have been established as study groups of programme management and project governance. In this paper, I'd like to explain the trend of PM international standard, including the past consideration. In addition, I'd like to state the expectations for the spread of Programme Management into Japanese business.
