What Skills Can Increase an Administrative Assistant III's Salary?

Demanded Skills for the Role:

  • Customer Service (Mentioned in 9.97% Job Postings): Customer service is the provision of service to customers before, during and after a purchase. The perception of success of such interactions is dependent on employees "who can adjust themselves to the personality of the guest". Customer service concerns the priority an organization assigns to customer service relative to components such as product innovation and pricing. In this sense, an organization that values good customer service may spend more money in training employees than the average organization or may proactively interview customers for feedback. From the point of view of an overall sales process engineering effort, customer service plays an important role in an organization's ability to generate income and revenue. From that perspective, customer service should be included as part of an overall approach to systematic improvement. One good customer service experience can change the entire perception a customer holds towards the organization.
  • Accounting (Mentioned in 2.93% Job Postings): Creating financial statements and reports based on the summary of financial and business transactions.
  • Purchasing (Mentioned in 1.24% Job Postings): Purchasing refers to a business or organization attempting to acquire goods or services to accomplish its goals. Although there are several organizations that attempt to set standards in the purchasing process, processes can vary greatly between organizations. Typically the word “purchasing” is not used interchangeably with the word “procurement”, since procurement typically includes expediting, supplier quality, and transportation and logistics (T&L) in addition to purchasing.
