When writing quality objectives, you need to keep in mind that the standard requires you to later measure level of their achievement. The best approach when it comes to defining the objectives is to make them S.M.A.R.T (Specific, Measurable, Attainable, Relevant and Timely) and this will enable you to meet requirements of the standard related to the objectives.
Planning achievement of the objectives includes defining actions to be taken, responsibilities, resources and deadlines for the activities. All these information, including the objective itself can be written in one document that contains all these information.
