General Administrative Theory at Tidy Tilda's (Scenario)
Penny owns Tidy Tilda's, a housecleaning service. She has been in operation for more than three years and has a steady client list which she hopes to expand as she tries to grow the business. She has ten cleaners who work for her on various assignments five days a week. The way she has structured the operation is that for each assignment, cleaners work in pairs, and for the occasional big job, in threes. Majority of her clients are homeowners, but occasionally she gets a bigger contract from offices and other businesses. The assignments usually take one day and the cleaners report into the office in the morning and at the end of their shift. For the occasional big job, which might take up to three days and three or four cleaners, Penny negotiates different terms. Penny's management style and techniques follow closely Fayol's principles of management as she aspires to build an adaptable organization.
