Activity is a process by means of which the subject realizes himself in the world, achieves goals, satisfies various requirements and masters public experience. Distinctive features of human activity is its focus, planned character and systematicity.
The most important components of any human activity - perception, attention, imagination, thinking, memory, the speech. To satisfy the requirements - to play, communicate, study, to work, - it is necessary to perceive the world, to represent what needs to be made, remembered, considered. That is, human activity is impossible without participation of mental processes. Besides, these processes not only participate in activity, they also represent special types of activity.
The theories claiming that internal processes can be formed by means of the external activity organized by special rules are developed. As a result of the transformations directed to automation and reduction of separate links, their transformations into skills, external activity gradually passes into internal, mental.
But any of mental processes does not proceed only as as internal, it surely includes also external, motive, links. Visual perception is connected with the movements of eyes, attention - with muscular contractions, touch - with the movements of hands. At the solution of tasks the articulation device almost always works, speech activity does not do without the movements of facial muscles and a throat. Therefore activity is a connection of mental and behavioural processes.
Activity, in difference from behavior, characterizes the conscious party of the personality. As stages of activity it is possible to allocate the following: 1. process of involvement in deyatelnost2. process tselepolaganiya3. designing process deystviy4. implementation process deystviy5. process of the analysis of results of actions, their comparison with set tselyamivpervy about process approach as area of a research of human activity were exorcized in 20 years of the last century. The research of efficiency of work of employees of the company with use of process approach was conducted. The head analyzed various interactions between employees, the scheme placement them indoors was made. By results of the analysis performed simple optimization - put the workers who are most often interacting among themselves nearby. As a result the notable gain in time turned out. It was the first example of carrying out optimization of processes in business. Process is the sequence of execution of any operations directed to creation of the necessary result. A basis of any process are three being focus, interaction and the sequence. Focus call ability to achieve a certain result - the purpose. It is an obligatory element of process approach to activity, an indicator of efficiency and assessment of all actions. Interaction defines as far as there corresponds the received result to needs of the consumer of this result. The sequence is the sequence of actions defining the direction of the further movement. Truly built sequence allows to reduce inefficient operations, to reduce duration of process and to achieve improvement of quality of result.
