In the process of personnel planning, it is necessary to calculate the planned need for labor. Various methods are used for this purpose. They are selected depending on the amount of available information and the skill level of the employee who carries out this work.
The most common methods are presented in the table.
Methods for determining planned labor requirements
Method Description
Correlation-regression Modeling the mathematical dependence of possible changes in the number of employees on various aspects. Expressed by a regression equation depending on the number of influencing parameters:
Чп = a+b×x_1+c×x_2+m×x_n,
where a is a constant, b, c, m are stockholder database coefficients that take into account the degree of influence of each factor, x is the real value of the factors.
Expert assessments Based on the opinion of competent experts. In case of uncertainty that may arise when choosing an option, special formulas or the Delphi method are used, which helps to find the optimal value.
Extrapolation Transferring past trends to the future. The method is simple, but excludes the possibility of taking into account future changes in the company's development process.
Balance sheet method Based on the calculation of the relationship between the resources that the company has available and their needs in the future.
Method of comparisons It is based on the analysis of similar numbers of competitors or partners.
Calculation from the achieved The staffing level is determined using a simple mathematical operation: the actual number of employees is multiplied by the planned index.
The staffing level is determined using a simple mathematical operation: the actual number of employees is multiplied by the planned index.
The total labor requirement is calculated using the formula:
Op=Tpch+Dpch,
Where:
Op - need for employees.
Tpch is the need to attract people to perform current tasks.
Dpch - the need for personnel for new projects or in case of an increase in the capacity of the enterprise.
When conducting personnel planning, the current need is determined by the number of planned vacancies. Additional need includes:
Need for positions in case of production development:
Dnp=Chpl-Chkg,
Where:
Чпл — staff numbers at the end of the period.
Chkg is the actual number of employees at the end of the year.
Demand for natural causes decreases:
Oak = Chsrt×Cube,
Where:
Chsrt is the average number of employees.
Cube is the coefficient of loss.

I have always been concerned about the issue of moving to a fundamentally new level. So that the indicators would grow not by 2 or 3 times, but by several orders of magnitude. From a thousand visits to ten thousand or from ten thousand to a hundred thousand, if we are talking about a website, for example.
And I know that such leaps are always the result of painstaking work in five areas:
Technical condition of the site.
SEO.
Collection of site semantics.
Creating useful content.
Working on conversion.
And at the same time, every manager needs an increase in sales and the number of applications from the site at the moment.
