Patterns for Effective Use Cases - Report Example

? Needs Document, Use Cases, and Scenarios Introduction Riordan Manufacturing has put a service request for the entire manufacturingsites to get an overview about all obtainable software applications in Sales & Marketing, Finance & Accounting, Operations, Human Resources, Legal and Information Technology. All the enumerated areas within the corporation are applying various business systems of which each of them gives challenges. On this basis, integrating system to facilitate customers purchasing products easily is projected. Automating most of the processes is the project the company has embarked. The need of ERP SAP system is a need of most of Riordan dealers and customers with which Riordan would be capable to exchange logistic and investment files for application of Electronic Data Interchange(EDI). This would simplify the procedure of data exchange and lessen high costs of printing and documents mailing. Problem Statement To incorporate their complex operations as well as create a better more receptive and proficient information technology. Project Goals To integrate the functioning of various departments and work locations by providing a common software platform which will acts as a common information system for the entire organization? The Project purpose is to alleviate the warehouse management system to allow easy purchase and recording of transactions. Systems Development Life Cycle (SDLC) gives efficient solutions to how the company controls its inventory and manufacturing procedures. Raw materials receiving, production, and the end product distribution are the three sections of inventory and manufacturing processes. Improvements in each of these sections will necessitate updating or fresh implementation of a computer system that will ensure accuracy, bestow unrivaled customer service, and most of all save the corporation money and time. Riordan existing system is a seven step procedure that includes a different document for each step. These procedures are costly and time consuming, which deter future growth toward expanding into an international organization. They include: Scheduled orders documentation; Receiving documentation; Raw materials or sub-assemblies documentation; Orders received documentation; Sub-assembly and end-product documentation; Sales order form procedures and Shipping documentation. Along with each of these procedures an inventory personnel is responsible inputting the information into a database or computer, which could imaginably be taken as 14 separate procedures. Through broad study, the research team believes that Riordan inventory and manufacturing procedure would be greatly enhanced by employing a Warehouse Management System, also known as WMS. According to Enterprise Resource Planning (ERP) expertise this system gives all subsections inside a venture. Project benefits A Warehouse Management System helps every division within the factory instantly and effortlessly to recover any and all essential records, shipping and receiving information. Riordan Manufacturing Company declares in the mission proclamation that one of the company’s goals is to make its commodities available to clients. Riordan Manufacturing will fruitfully achieve the goal of making the company’s products available to customers by employing the use of shipping tag printers, hand held computer devices and an Intelli Track Software system with the ability of printing. An Intelli Track Software system would link the whole corporation through a LAN. Production will be hugely increased through the improvement of real time once this streamline is applied. Having innovative functioning methods will give management a clear, imminent vision on how to give superior traceability. In terms of the end product distribution, an Order Fulfillment System or OFS will vastly advance any system that helps in fulfilling a client order. Implementation of an OFS normally comprises a WHS. An OFS is a technology that re-palletizes and de-palletizes commodities for delivery to a sales center.  OFS systems usually vary greatly. The involvedness and size of an OFS technology is typically limited to the dimension and complexity of imagination. Solution switching to an automated technology for inventory organization and shipping processes will improve operations considerably. The need of ERP SAP system is a necessity of most of Riordan dealers and clients with which Riordan would be capable of exchanging logistic and finance documents for application of Electronic Data Interchange. This would make simpler the procedure of data exchange and decrease high costs of printing and files mailing. In addition, implementation of SAP will let Riordan to get know-how and best practices from the corporation responsible for the implementation. Very significant aspect is also that ERP technology brings unification of corporation standards and documents. Additional gain of ERP system implementation: An integrated system for all Riordan firms and offices centrally managed single unit that will give all company locations with well-organized reports with concurrent statistics, Reduction of statistics redundancy, and discrepancy across all plants economic savings because of the concentrated quantity of server hardware operating cost. Financial savings on extremely trained information system personnel for integrated ERP system situated only at one Riordan location Optimize cost and augment revenues. Computation and management of prime costs verses revenues Riordan Manufacturing could generally use some updating of their business technology throughout their subdivision Finance & Accounting, Operations, Sales & Marketing, HR, Legal and Information Technology. Where Riordan has some commerce systems in place currently, a lot of manual monitoring is still going on in the company. In general, the focus involve putting into practice company-wide systems where information can be centrally stored, maintained and retrieved. Stakeholders The research team Board of directors Company managers IT personnel Return on the investment(ROI) A performance gauge used to assess the efficiency of a speculation or to contrast the efficiency of a number of diverse investments. To calculate ROI, the gain (return) of an investment is divided by the charge of the investment; the outcome is expressed as a percentage or a ratio. The ROI formula: Projected cost of the projected cost of the product equals $ 500,000 and projected gain after one year would be $100,000 This is a 20% ROI 100000/500000*100 Resource estimates It is essential to spend funds upfront in IT or System projects in order to avoid over spending during the project. Requirements Typical cost of implementation User requirement $ 1000 - %10000 Coding unit testing $ 1000 or more System testing $ 7000 - $ 8000 Hardware requirements $ 100,000 Network $ 10,000 Expertise $ 20,000 - 50,000 Training $ 100,000 Risks Not implementing the project means that the company will retain the status quo thus not capitalizing on strengths and opportunities. Online services faces security risks due to hacking. Like the rest, implementing the project implies security risks are increased. Use case 1 Use case name: Customer order a product Summary A customer go online to purchase a product from Riordan Manufacturing Company. The OFS system enable the customer to order the product and alert the warehouse clerk about the order for packaging and shipment. Actors: warehouse clerk, customer Precondition: customer manages to place an order for a product and pays for it. Description (Ideal situation) 1.
