Valuation is a process to establish a value for an entire company or partial interest in a closely held business or professional practice, taking into account both quantitative and qualitative tangible and intangible factors associated with the specific business / interest being valued.

The valuation is performed in a variety of contexts and for a variety of purposes. A valuation is not an exact science. The value is subjective term and can have different connotation.

This implies the business value must be measured and defined by a "Standard of Value" that is relevant, meaningful and reliable.
