μ Number of workers employed
μ Volume of production or turnover of business

The countries with such definitions have recorded a higher growth rate in the SME sector. This indicates that the more precise the definition, the more effective the transaction of policies intended to benefit the sector with actual results. In countries where no definition exists,
