TAM services typically involve the stocking of the full range of uniform items (head-to-toe) worn by a customer. If a particular uniform is purpose designed and unique to that customer, then the number of employees must be sufficient and the contract arrangement of sufficient length to achieve the necessary economies of scale. As a general rule, organisations would need to have several hundred employees as a minimum to achieve the full benefits of TAM.
The range of TAM services provided varies greatly too, which likewise has an impact on the costs associated in servicing a customer. The outsourcing of TAM services to S&H provides the customer with their own economic benefits (such as the removal of warehousing space requirements and a reduction in working capital requirements) whilst seeing increased service levels and reduced transaction costs.
