Which of the following plans are part of the operational planning process?

Both of these

The correct answer is option 3 i.e. Both of these.

Single-use and standing plans are part of the operational planning process.

* A single-use plan is developed for a one-time event or project. Such a course of action is not likely to be repeated in future, i.e., they are for non-recurring situations. The duration of this plan may depend upon the type of the project. It may span a week or a month. A project may sometimes be of only one day, such as, organising an event or a seminar or conference.

* A standing plan is used for activities that occur regularly over a period of time. It is designed to ensure that internal operations of an organisation run smoothly. Such a plan greatly enhances efficiency in routine decision-making. It is usually developed once but is modified from time to time to meet business needs as required.
