Abstract
<jats:p>This paper examines the time costs associated with interpersonal interactions that accompany the collective resolution of production and educational tasks by a group of individuals. Interpersonal interactions are an integral part of teamwork, ensuring action coordination and experience exchange. Managing these interactions and standardizing the time spent on them is a subject of study in organizational system management. Brooks’s Law explains the quadratic growth in the number of interpersonal interactions in production groups as their size increases. This work proposes an empirical method for standardizing time spent on each such interaction, as well as the overall task labour intensity, based on Brooks’s Law deriving an equation to link these two parameters. The work considers three methods for experimentally determining the values of these two parameters. The simplest method of solving a system of two linear equations proved unsuitable due to the significant impact of measurement errors on the results. The two proposed time standardization methods are based on mathematical statistics, fuzzy logic, and multiple experiments. The paper also compares the labour intensity of tasks with varying degrees of heterogeneity. The labour intensity of such tasks and the proportion of time costs for interpersonal interaction among group members during their solution are experimentally calculated. During standardized interactions among members of production and educational groups, there is an exchange of knowledge, experience, corporate culture formation, and emotional climate. All of this collectively represents an important intangible resource for production. Therefore, in conclusion, the paper proposes not to consider the time spent on interpersonal interactions as a cost.</jats:p>
