Planning is the process of thinking about the activities required to achieve a desired goal. It is the first and foremost activity to achieve desired results. It involves the creation and maintenance of a plan, such as psychological aspects that require conceptual skills. There are even a couple of tests to measure someone’s capability of planning well. As such, planning is a fundamental property of intelligent behavior. An important further meaning, often just called "planning" is the legal context of permitted building developments.
Also, planning has a specific process and is necessary for multiple occupations. In each field there are different types of plans that help companies achieve efficiency and effectiveness. An important, albeit often ignored aspect of planning, is the relationship it holds to forecasting. Forecasting can be described as predicting what the future will look like, whereas planning predicts what the future should look like for multiple scenarios. Planning combines forecasting with preparation of scenarios and how to react to them. Planning is one of the most important project management and time management techniques. Planning is preparing a sequence of action steps to achieve some specific goal. If a person does it effectively, they can reduce much the necessary time and effort of achieving the goal. A plan is like a map. When following a plan, a person can see how much they have progressed towards their project goal and how far they are from their destination.
; part of the basal ganglia; neural pathways between the striatum and the frontal lobe have been implicated in planning function.
Planning is one of the executive functions of the brain, encompassing the neurological processes involved in the formulation, evaluation and selection of a sequence of thoughts and actions to achieve a desired goal. Various studies utilizing a combination of neuropsychological, neuropharmacological and functional neuroimaging approaches have suggested there is a positive relationship between impaired planning ability and damage to the frontal lobe.
A specific area within the mid-dorsolateral frontal cortex located in the frontal lobe has been implicated as playing an intrinsic role in both cognitive planning and associated executive traits such as working memory.
Disruption of the neural pathways, via various mechanisms such as traumatic brain injury, or the effects of neurodegenerative diseases between this area of the frontal cortex and the basal ganglia specifically the striatum, may disrupt the processes required for normal planning function.
Individuals who were born Very Low Birth Weight and Extremely Low BirthWeight are at greater risk for various cognitive deficits including planning ability.
.|alt=A version of the Tower of Hanoi utilizing four discs.
There are a variety of neuropsychological tests which can be used to measure variance of planning ability between the subject and controls.

In test participants with damage to the right anterior, and left or right posterior areas of the frontal lobes showed no impairment. The results implicating the left anterior frontal lobes involvement in solving the TOL were supported in concomitant neuroimaging studies which also showed a reduction in regional cerebral blood flow to the left pre-frontal lobe. For the number of moves, a significant negative correlation was observed for the left prefrontal area: i.e. subjects that took more time planning their moves showed greater activation in the left prefrontal area.
Public policy planning includes environmental, land use, regional, urban and spatial planning. In many countries, the operation of a town and country planning system is often referred to as "planning" and the professionals which operate the system are known as "planners".
It is a conscious as well as sub-conscious activity. It is "an anticipatory decision making process" that helps in coping with complexities. It is deciding future course of action from amongst alternatives. It is a process that involves making and evaluating each set of interrelated decisions. It is selection of missions, objectives and "translation of knowledge into action." A planned performance brings better results compared to an unplanned one. A manager's job is planning, monitoring and controlling. Planning and goal setting are important traits of an organization. It is done at all levels of the organization. Planning includes the plan, the thought process, action, and implementation. Planning gives more power over the future. Planning is deciding in advance what to do, how to do it, when to do it, and who should do it. This bridges the gap from where the organization is to where it wants to be. The planning function involves establishing goals and arranging them in logical order. A well planned organization achieve faster goals than the ones that don't plan before implementation.
