Pacific Green Company (PGC) provides landscaping services to individual and corporate customers in southern California. Heather F originally founded PGC as a lawn mowing service while she attended graduate school. It became so successful that she delayed her teaching career to concentrate on building the company. This case describes PGCs landscaping jobs (sales) process.

After the customer contacts PGC about a landscaping project, a PGC manager prepares a quote describing the scope of service and the price. After reviewing the quote and comparing PGCs quote to other landscapers, customers may 1) accept the quote, 2) notify PGC that they did not get the job, or 3) request that the quote be modified. If the customer accepts the quote, they sometimes request that the project be completed in a series of jobs. Each job is handled separately. Jobs are then performed according to an agreed upon schedule until the overall project is complete.

Each landscaping job generally proceeds as follows after the contract for the job is signed. The PGC manager responsible for the quote assigns the trucks and selects the plants for the job. Then, the manager assigns the job team: the job supervisor, truck drivers, and landscaping laborers, to the job. At that point, the PGC job team performs the job. Customers must pay a 10% deposit when the job begins (that payment is made when they sign the job contract) and the final 90% is due when the job is completed. Customer payments are made by check or credit card and processed for daily deposit by a PGC cashier. After PGC starts the job, the cashier bills the customer for the remaining 90% due. Customers either make the final payment or demand rework to bring the job up to the contract requirements. When the job is completed satisfactorily, the customers then pay the amount due. Occasionally, some deadbeat customers withhold further payment for unknown reasons. In that case, PGC either refers the debt to a collection agency or writes off the remainder of the amount due. Of course, PGC does not perform the remainder of the jobs in the project when the customer fails to pay.

Required: (1) Draw a basic BPMN activity diagram for the sales and collection process described above.

(2) Develop a refined activity model for this process. (You may need to use elements like pools, lanes, intermediate events, subprocesses, etc.)
