If all production was sold and consumed, gdp would be easily measured. Outputs of one company are imputes for others. Measuring value of output counts some output more than once. Measuring gdp is about measuring final production. To avoid double counting- measure value added by all firms. Value added is sales revenue- cost of intermediate goods. Value added is definitionally equal to wages paid to workers plus profits paid to owner. Total of all added in the economy is a measure of total output. Gdp is the total value of final goods and services produced. Wide range of approaches to measuring gdp. Value added by all firms in the economy.
