EPC is an abbreviation for Event-driven Process Chain, and is a flowchart based diagram that ca be used for resource planning and identifying possible improvements of a business process. Businesses use event-driven process chain diagrams to lay out business process workflows, originally in conjunction with SAP R/3 modeling, but is now more widely used by many companies for modelling, analyzing, and redesigning business processes. This will be preliminary exercise before utilizing BPMN 2.0 in the group project in Assignment 3.
In this assignment you will use Signavio, (see the activity in week 3 for creating a Signavio account) to prepare an EPC diagram for the Case Study below. Make sure to identify the organizational units and actors relevant to the case study and indicate on the EPC diagram the actor that is responsible for each task in the process.
MouldPlast is a plastics component subcontractor in the airline and automobile industry. They specialize in products that must meet very high quality standards. The nature of their business requires high standards of the production where all the processes and procedures are followed, traceable and auditable. These requirements are placed on them by their customers, and failure to meet them would be a serious impediment to their business.
You have been called in to document and improve their pre-production procedures. This includes receiving and storage of materials used in manufacturing. When materials five arrive, the receiving first arrive, the receiving clerk confirms the shipment by comparing the shipment to the purchase orders on file. In most cases, materials can be matched with Purchase orders. On the occasion that they cannot be matched, the relevant Purchasing Officer is ungently notified of the materials to confirm that the materials have not been ordered as in some instances, suppliers substitute alternatives for an order. In the case that the materials have not been ordered, the materials are refused.
The receiving clerk the sorts the materials into two different categories; perishable and non-perishable and assigns a material number. The materials are then planed in one of the quarantine areas that are appropriate for the types of materials. A ‘Materials in Quarantine’ notice is sent to Quality Control for all the materials. In the case of perishable materials, a copy is also sent to the materials lab. This note lists the name of the materials, its location, the quantity, and the material number.
On receiving the ‘Materials in Quarantine’ notice, Quality Control inspects the materials and determines their suitability and assigns a material number. In some instances, they need to determines the suitability and assigns a material number. In some instances, they need to have tests run by the Materials Lab to determine the suitability of the materials, so a Lab Inspection request is sent to the Materials Lab. The Lab return an ‘Inspection Report’ to Quality Control commenting on the suitability of the materials. The ‘Lab Inspection request’ notes the tests that need to be performed on the materials.
If the materials fail to meet the required standards, Receiving, Production and Purchasing are advised with an “Unsuitable Materials’’ notice. Receiving attaches, a ‘Reject Notice’ on the materials and moves them to a reject area for disposal and advices Purchasing of the rejected materials. Purchasing is responsible for determining the procedures for disposal of the material (this may involve returning the materials to the supplier or destruction of them).
