Henkilövuosi

Henkilövuosi, often translated as "person-year" or "man-year," is a unit of measurement used to quantify the amount of work performed by one person over the course of one year. It represents the full-time employment of one individual for a standard working year. This concept is widely applied in various fields, including project management, economics, and labor statistics.

In project management, henkilövuosi is used to estimate and track the resources required for a particular task or project. It helps in planning the timeline, budgeting, and determining the size of the team needed. For example, a project requiring 10 henkilövuotta of work would suggest that one person working for 10 years, or 10 people working for one year, or any combination thereof, would be needed to complete it.

Economically, henkilövuosi can be used to measure productivity and labor input. By calculating the total output per henkilövuosi, economists can assess the efficiency of a workforce or an industry. It is also a common metric for comparing the labor intensity of different economic activities or countries.

In statistical contexts, labor surveys often report employment figures in terms of henkilövuosia to standardize comparisons of workforce size and contributions. It allows for a consistent way to aggregate and analyze employment data across different periods or sectors, regardless of variations in individual working hours or contract lengths. The definition of a "year" within the context of henkilövuosi can vary depending on the specific industry or national standard, but it generally refers to a full-time working year.
