Again, since the learning program is based on the pace and time of the managers himself, great time management skills are needed on part of the manager. Thus if some manager is lacking in this department, then the open learning method is not for him.
One final drawback of the open learning method is that it is not for those who are not familiar with technology. Listen to a lecture through the computer screen might seem unnatural to those who are more adept to the natural method of teaching. In addition, testing, learning, most of it takes place through the computer which all require a good deal of computer skills that might not be possessed by every manager, especially the senior ones who are not particularly adept at technology (Guirdham 2002).
再次，自学习计划的基础上，速度和时间的管理，时间管理技能的需要，对部分经理。因此，如果缺乏这部经理，然后打开学习方法不是对他。
最后一个开放的学习方法的缺点是，它不是为那些谁不熟悉的技术。听讲座通过电脑屏幕看起来不自然的那些谁更娴熟的教学方法。此外，测试，学习，最重要的是通过计算机，都需要大量的计算机技能，可能不具备的每一个经理，尤其是老年人谁也不是特别善于技术（guirdham 2002）。
