nikdorinn [45]

Answer:

A service department that I would create for a product from Appliance Warehouse is:

The washing machines service department.

Explanation:

Appliance Warehouse is one of the most important if not the most important washer and drying machine leasing company. So, they require a very good service department for them. Thus, I would develop one very innovative service department with an online application that would allow performing this job with an outsourcing labor force making it cheaper or us. The recruitment would be based on the different washing machine brands certification as a service and repair provider technician. We would also select them based on consumer service orientation and will create a database on the platform. This platform would be categorized by county, let us offer it for our selected local service outsource technicians. We would make an agreement with them for the database in the form of a services contract that would set a diagnosis and a services fee. We would also have an inventory of machine parts and we would only charge 20% of the cost of the services. We would establish the fee and we would also sell the costumer the fee for the parts used to fix the machines.

For example,

 string abc;

string uppercase= abc.ToUpper(); // gives ABC as result
