Riordan: Development of an ERP System Final Report BSA 400 Enterprise Resource Planning System Statement of Scope and Goals RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 2 Riordan Manufacturing, a fortune 1000 organization was established by Dr. Riordan, a lecturer of chemistry, having a number of patents related to processing polymers into higher tensile strength plastic material substrates. Realizing the industrial uses for his patents, Dr. Riordan established Riordan Plastics, Inc. during 1991. The organization has their company office in San Jose, CA having 125 workers, a plastic beverage bottle factory in Albany, GA having 45 workers, a customized plastic parts factory in Pontiac, MI having 130 workers, and a plastic fan factory in China having 250 workers. All those offices and or factories place their info on a variety of computer systems. Riordan Manufacturing presently has a legacy MRP Information System set up. The assessment will offer info for the organization in order to update its system. The update of the system will take into consideration the following: Cost Constraints Risk Benefits Riordan Manufacturing would wish to have an assessment for the development of an ERP system to monitor and control raw materials and a finished product stock throughout all factories. Depending on the assessment, Riordan will increase their production by using a latest ERP both for the clients and the organization. Riordan will perform the following: RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 3 Update their system to monitor stock correctly and control raw materials and finished products. Decrease stock cost of raw materials and finished products. Improve MRP infrastructure. Supporting Measures for Success The execution of an ERP for Riordan Manufacturing will let a full understanding of the day to day functions throughout all of its factories, and a reliable purchase and use of raw materials to assist optimize savings over the life cycle of its products. Being a leader in the industry in the plastic injection molding Riordan Manufacturing must be in charge of those areas in which purchasing raw materials and manufacturing of items seem sensible to its company procedure. The execution of an ERP will let Riordan Manufacturing to have understanding of the industries for which it produces items and for that reason keep stock to fulfill the requirements of its customers. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 4 Just like all production industries Riordan Manufacturing is impacted by economical prediction of the industries that it acts, however this understanding alone doesn't offer adequate understanding to know exactly how internal sections react to economical changes. The effective execution of ERP will produce palpable savings through purchase of materials to fulfill the requirement of the beverage, army, automobile, and healthcare sectors, and the way the information gathered with each item order is an easy procedure used over all of the sections. Presently Riordan Manufacturing holds an inventory worth 3,727,922.40 to fulfill orders for its clientele nevertheless; this stock of parts requirements store real state, specific warehouse equipment, and time for handling and audit across several computers systems over the organization. But with the execution of an ERP system there will be an accountable purchase of materials in line with the info supplied by demand and supply strategies which will consequently provide adequate information to have a lower stock of raw materials and finished products, yet still be a responsible partner mindful of the customers’ requirements Requirement Analysis Project Feasibility Study RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 5 Team B will show that it's technically feasible and economically beneficial for Riordan to employ the latest ERP System which meets the objectives which have been established for the organization. Carrier expenses would be decreased by roughly 35% of present expenditures by the usage of a far more integrated delivery method that may direct and combine deliveries automatically to enable them to be delivered to typical addresses in shared packaging. While main carrier would off discounts when Riordan linked into their invoicing system, the ERP system would help this, which would be an additional cost savings of 15 %. Shortages of supplies from vendors are also expected to be decreased and improved by 5% in the beginning and increasing to 20% during 2 years, because of the removal of hand written Purchase Orders and the automatic Cycle Count abilities and reviews. Improvements to stock precision are also expected to be decreased and improved through similar numbers because normal cycle counts progressively correct stock balances, and also the utilization of digital bar code methods and marking to assist avoid wrong counting of piece parts. Proposed Systems Requirements Riordan Manufacturing’s uniformity of activities and quality control rely on methods that need assessment to better monitor and handle raw materials and stock of deliverable materials. Execution of an Enterprise Requirements Planning (ERP) system will have the consequence of integration of existing Information Systems to satisfy company needs at all of Riordan’s production sites. A highlevel performance for the benefits of a advanced ERP system which will RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 6 provide improvement in Riordan company procedures are divided into 9 stages fulfilling the scope of the suggested venture and explain the range of activities to successfully develop the ERP system. Highlevel overviews of the related project needs consist of (Motiwalla & Thompson, 2009, p. 63): Procurement: Purchasing is the procedure in which suppliers provide goods for operating companies. This procedure will include supplier showing, quotes, assessment and lastly choice. Purchasing will likewise incorporate allotment of organization owned devices e.g. laptop computers to its workers. It will maintain check of organization property and cope with damages. Production: Output analyzes needs using Riordan company system evaluation and current legacy systems. Output will additionally make certain smooth running of procedures in live atmosphere. Accounting: Pricing of software program, computer hardware, maintenance, and labor hours. Distribution: shipping of essential software program, computer hardware, and staff (implementers and contracted supplier support) to each of Riordans production plants. Customer Services: Customer support will be an integral part of Riordan ERP. An effective ticketing service together with monitoring will be maintained in the ERP to make sure interaction with Riordan administration regarding execution status, functionality and any shortfalls experienced. Performance and Governance: Every quarter assessments of all workers will be completed to make sure favorable and competitive working conditions. Human Resources: Human Resource will consist of methods which cope with every aspect of a worker. It includes hiring, training a worker, payroll, advantages and firing. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 7 An extensive ERP execution strategy will meet Riordan’s costs, scope, and time limitations of going operational through specific timeline goals. To achieve the development and eventually execution of the ERP will need the highlevel requirements mentioned above are completely exploited to identify system performance and feasibility. These types of low level functions are acquired after making consumer tales which together achieve the higher level needs. After assessment of system performance is established current company procedures will be assessed to find out customization and integration of Riordan’s legacy systems. The ERP will be a crucial part of Riordan’s capability to monitor its raw materials and stock of manufactured items. The ERP info system offers “automation to support Riordan’s this kind of company functions as accounting, finance, advertising, customer support, human resource management, and operations” (Motiwalla & Thompson, 2009, p. Determination of Requirements Team B has got the chance to find out the requirements of the workers of Riordan Manufacturing. We have decided to achieve this by following people around, group interviews, and prototyping. By carrying out these group interviews and following people around, Riordan’s stock division is presently manually entering inventory. Riordan would benefit from an automatic scanning system which will automatically upgrade when an item is ready for stock or RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 8 sold. Depending on the information we received, we decided that the accounting and finance division should modify their existing financial process. In order for Riordan to get the largest bang for their money, they should be sure to execute the system nationwide. This system will let the following: Tailored reports Charges Payment posting Collections Prototype Team B will be using prototyping to find out the requirements of Riordan Manufacturing. Riordan Manufacturing has been successful so far however it is necessary for them to execute an ERP system so they can take their company to the next higher level and continue competitive in today’s market. Riordan should know where their weak point lies so we can improve them; here the ERP system will come into play. Team B will suggest that Riordan Manufacturing use a prototype process, this will examine all the information from group interviews, and following people around. This will let to check the prototypes with the information and satisfy the RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 9 stakeholder’s requirements. “This model works best in situations where not all of the project needs are known in detail ahead of time. It is an iterative, trialanderror procedure that takes place between the developers and the users” ("SearchcioMidmarket," 2007, para. 1). Confirmed Requirements This document shows the list of verified needs as a consequence of comments from the team’s determination of needs for ERP development. Each requirement is either compulsory or elective using info of present procedures. Additionally contained in the document is a reasonable view of the information movement external and internal to Riordan’s 4 sites. Discussion regarding the variations of the present system data movement and also the suggested ERP system shows the advantage of using the latest system. The analysis groups met up with each of Riordan’s project administrators to assess present procedures at the Albany, Pontiac, Hangzhou, and San Jose sites. Meetings included queries of present system performance, versatility, dependability, ease of use, and supplier satisfaction. Assessment of the information from Riordan customers, practical proprietors, and information systems managers is the foundation for arranging and assessing Riordan’s company requirements. The present network facilities quantity of servers, workstations, and present software program (operating system and programs) has been ideal for dealing with the production and delivery of Riordan’s raw materials. Comprehensive research into the company’s RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 10 resources and capabilities is important for personalization of an ERP program to migrate Riordan’s present info. It's with confidence that the improvement or purchase of a good ERP system as a consequence of the determination of needs will make monitoring and maintaining raw materials for Riordan sites more effective. Purpose Integration of present info existing on systems found in Albany, Pontiac, Hangzhou, and San Jose company head office having the improvement or purchase of an Enterprise Resource Planning system. Scope A listing of verified needs depending on comments from Riordan functional administrators, input from stake holders, GAP assessment of present system performance and possible ERP performance, and overview of determination of needs outlined in the request for proposal and preliminary evaluation. Riordan’s board of directors is accountable for the company’s operation according to state requirements, Articles of Incorporation, and bylaws. Therefore the board offers the oversight of RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 11 quality control and controls the path of the venture with the investors’ best interests. Coordination with Riordan’s management will help the analysis and answer to make sure info obtained is correct. Assessment of Riordan’s present network facilities with regards to combining an ERP system for business wide use it was essential to classify needs taking into consideration appropriateness of Riordan’s use, system characteristics, and advantages. Six factors in narrowing the determination of needs right down to an appropriate listing are displayed in table 1.1 Enterprise Resource Planning Requirements Considerations Item Description Mandatory/Optional Functionality ERP characteristics meet the Obligatory requirements of the client Onsite Options Present software program offers Elective choices for SaaS through Web interface. Configuration Flexible to personalization to satisfy Obligatory particular requirements of Riordan. Implementation Strategy Availability of educated experts to Obligatory apply data migration and assistance making certain congruency of all RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 12 Riordan sites. Evaluation of Components Assessment and coordination of Obligatory present systems for probable changes, e.g., computer hardware updates or software program purchase. Data Migration Moving present info; Code change for Obligatory unlike data formats. Table 1.1 – ERP Requirements Considerations Method The data utilized in compiling this document was accumulated by surveys which outlined the listing of needs on a weighted scale of 1.00 to 5.00. Surveys were made readily available for 550 workers; 400 from the 550 surveys were returned. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 13 Questionnaire for Requirements Determination Location Number of Number of Total Returned Employees Questionnaires San Jose 125 125 115 Albany 45 45 40 Pontiac 130 130 125 Hangzhou, China 250 250 120 Arbitrary oneonone job interviews were carried out with system users to find out exact user needs to increase credibility to the figures put together from the surveys. Video teleconferences were planned to have comments from the different Info System leads to determine present systems and software program abilities. The data gathered was examined and a reasonable opinion (combined) of Riordan’s procedures were mapped, see information movement diagram. Findings RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 14 Assessment shows that there isn't any database server mentioned for any of Riordan’s sites. The absence of a core database for information input, saved, queried, and applied doesn't offer the need for versatility or performance. Riordan manufacturing factories transfer information through a T1 fractioned 256 MHZ line against a satellite feed from the China factory. An execution technique for information duplication from the satellite feed to take into account weather conditions aswellas big data loads to deliver gets essential for dependable stock of motor components for the fans produced at this site. From the 140 customer systems 65 are utilizing an operating system no more based on Microsoft. Depending on the assessment of Riordan’s enterprise facilities the onsite choices for utilizing current systems for data integration/migration will need either an operating system update or substitution of systems with thin client technology. Accessibility to a core database through thin clients accessing the working ERP servers at every site will decrease the admin footprint to transmit experts to every site in order to upgrade software program or make any changes. A reasonable view of the suggested company procedures is displayed in the following diagram and will better satisfy the listing of needs noted. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 15 Following assessing the Determination of needs at Riordan Manufacturing 5 obligatory and something elective necessity will make sure achievement of the venture. Following the listing of needs ERP improvement or purchase will result in much better monitoring and keeping of the company’s raw materials. Substitution of outdated systems with thin clients and establishment of a main data archive additionally increases the functionality, versatility, dependability, ease of use, and organization satisfaction with the item. Functional Allocation RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 16 The running part for Riordan Manufacturing’s ERP will be allotted at the accounting, stock, manufacturing, and sales stage. The allocations of systems will have in consideration the minimal needs because suggested for function at the system and user level.

Absolutely no Media. The share of software and hardware for the specified company levels provides a substantial benefit to the way in which Riordan manufacturing presently does business; nevertheless there are factors which have to have a organized implementation, because there will be a requirement for training at these company levels to make sure a collective perception of procedures and benefits of the solutions. On the contrary the execution of the ERP with the recommended hardware and software improvements will permit a far more effective control of stock, purchases, production line materials, deliveries of finished products, and invoicing. These types of improvements include the integration of solutions along with a cross sharing of information to the sections from the Cosona ERP system. In addition to that the centralization of data enables a smooth interaction of the sections along with mission crucial information for manufacturing operations. Process View RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 20 This report shall describe regarding the process view by which the needs for Riordan Manufacturing’s latest system shall be applied. The process view is explained by a flowchart in MS Visio. Preliminary Design RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 21 The initial design for Riordan Manufacturing pays special attention to the interconnection among the production factors and understanding the priority of the services on which these depend on. The system for Riordan Manufacturing at its sites except for the main office in San Jose will be completed with a Cisco 3700 series router. This device has got the capacity for dealing with the bandwidth requirements for every site and possible development with additional users or devices. “With on board LAN/WAN connection, latest higher density support modules, and assistance for several sophisticated integration modules, the 'Cisco' 3700 Series Multiservice Access Router provides latest levels of service density for department offices in a compact type factor.” (Cisco, n.d.) Additionally every site will have software program firewall services which will be supervised and managed by the system devices. At the San Jose locations the needs for the site requirements adequate managing of bandwidth for inbound and outbound traffic in addition to a sound server structure following the suggestions designed for operations of the ERP system. The system links for the San Jose office are supervised and managed by a Cisco 7500 series router combined with software and hardware firewall services in a layered framework to manage risks to the network. This product supports LAN/WAN services together with optimization of service via greater accessibility and bandwidth aggregation. “A distributed structure utilizing RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 22 Versatile Interface Processors (VIPs) is key to the Cisco 7500’s scalability. Each VIP has got its own processor chip that is able to switching over IP data packages and offering network services.” (Cisco, n.d.) . At the server degree the ERP system will use a Dell PowerEdge server which is stand mountable, this kind of server permits the utilization of the present server facilities, while reducing the usage of area and reduce carbon dioxide impact. Additionally the server will be utilizing Windows server 2008 which will increase versatility and functionality of the ERP with the end user interface, regardless of whether this particular interaction is thru the usage of workstations or thin clients workstations. Additionally the Cosona ERP stock and administration system will offer the company units with the required information to process requests and satisfy the requirements of the organization and its clients. The user level would be the stage in which a dedication must be created on the initial design because there are power users and special task which might need various configurations to do at adequate levels, while getting the benefit of the ERP system. Design TradeOff Approach RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 23 The ERP will improve the data movement throughout the whole organization, and permit direct access to real time actions. ERP system handles all factors of one’s company including buying, sales, accounting, and customer support. With the integration of ERP it will get rid of counter production issues that might impede the company as a whole. What one should additionally know is that there are 2 parts to the subset, for example CRM and MRP. One should keep in mind for a venture this large together with several sites it would be impossible to generate a sole program. Riordan manufacturing has got 3 factories in the USA and one factory in China, therefore one should keep in mind when applying a program it needs to be created with all the sites in mind, because no common ERP system will work for China and the USA sites. One should consider the economical and social variations. Riordan manufacturing will also have to work with a business which can create a software program for their China site, because the ERP system for the USA sites won't work in China, this will be a additional expensive that should be figured in. “While administration applications have been built into western company tradition over a number of years, in China these systems have just been launched a lot more recently. Stories of unsuccessful execution of administration systems are frequently heard in which administrators have expended substantial money and time and internal resources simply to meet with bad results”. One more thing which should be checked out is the language hurdle, when the project administrator or other IT staff doesn't speak the language this might be a big hurdle, therefore one should additionally figure in a language advisor. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 24 Detail Design Process The detail design procedure summarizes the requirements for setting up a company Resource Planning system which workers will access from each of the company’s production sites. The procedure includes the design of ultimate decisionmaking to pick the right computer hardware, software program, and interfaces. The detail style procedure is a sixstep iterative procedure that starts with the conceptual layout like shown in figure 1. *ERPApplicationServer *ERPApplicationServer ChangzhouChina Ponti,MI ERPThinClient *ERP BackupServer ERPThinClient *ERPMainDatabase SanJo,CA *RecommendedHardwareRequirements ERPThinClient -PentiumIVprocessor -Speed1GHZ *ERPApplicationServer -Memory1GB Alba,GA -Disk20GB Figure 1 – Riordan Manufacturing ERP Conceptual Layout RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 25 Second step involves the subdivision of the ERP system, like shown in figure 2, to find the individual elements to consider in designing Riordan’s ERP system also referred to as the initial design. The ERP system subdivision form in this stage is representative of the execution determining internal and external sources, e.g., purchase of parts or utilizing current parts. Figure 2 – ERP generic structure tree Third step of the detail design procedure entails choice of the ERP elements which follow the determination of needs choices in the initial phase of the procedure. The development of Riordan’s ERP system will be a mix of overhaul to current elements and freelancing of supplier parts. It is essential to remember that this phase is a repetitive procedure that will need RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 26 continuous development of design and mapping of the several functions to satisfy Riordan’s requirements. It is thru the repeated procedure for drawing out the initial ideas which any choices regarding the interface and plugin of elements. Fourth step sees the integration of the ERP system elements combine for a finalized setting. Began in the first step together with the choice and freelancing of elements a model starts to develop. As soon as integration of all of the parts is finished a final design of the ERP system to incorporate the external and consumer interfaces, demonstrated in Figure three and four, and suggested set up is available with regard to checking on a prototype ERP system. External interface requirements identify the computer hardware, software program, and database part of the ERP system. In order to connect with the external parts of the ERP system the detail design procedure deals with each as follows. Computer hardware interface needs rely on the dimensions and volume of Riordan’s data and will be reducing computer hardware usage leading to much better system performance and durability. Hardware Minimum Recommended Processor Pentium III Pentium IV Speed 600MHZ 1GHZ RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 27 RAM 1GB 2GB Hard disk 10GB 20GB Figure 3 – Hardware Interface Requirements (CNet Software Technologies Plc., 2011, p. 81) At each of Riordan’s manufacturing plant sites the ERP system application and Oracle database will be accessible and shown on the thin client while accessing the ERP program at the San Jose site. The computer software interface offers the required protocols of the ERP interaction for all Riordan factories. Software Interface (S Capabilities #) S1 Create capacity with approved logon S2 Notification/send capacities for message notification S3 Delivery/receipt notice capacity S4 Will be compatible with current Riordan applications and CDMA tools to identify automatically any computer software upgrades software program which can be downloaded from the server. Figure 4 – Software Interface Requirements (CNet Software Technologies Plc., 2011, p. 82) The user interface describes the systems capability to permit users to interact with the application and data saved in the database. By having a central ERP server and data archive the interface RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 28 must offer simplicity of use in navigation, information entry, and database issue. The following factors will help effective ERP use. ARP application interface or system modules must utilize drop down menus, check boxes, and listings as a substitute for text fields in order to reduce data entry mistakes Design of the interface/frontend of the ERP application for simplicity of use no matter who is using the system, e.g., dock employees, administrators, system managers, and so on. Compatibility with peripheral devices, for example computer printers, bar code readers, scanners, and any other device which will help data entry and output. Fifth step starts the simulation or prototyping of the ERP systems performance against the design specs and Riordan’s company procedures. The outcomes of the testing work as a tool for more explanation of the systems achievement or deficits. Developers will use the data gathered during checking in order to fix trouble spots and advance the procedure to the last stage of completion. Sixth step of the procedure requires the completion of the development of Riordan’s SRP system to incorporate authorization (approval of development) by Riordan Manufacturing. It is in this stage that the system criteria, for example system dimensions, Riordan’s manufacturing procedures, system tolerance, and restrictions, and system capabilities are set for production. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 29 Paperwork of the ERP system is an essential part of going operational. Paperwork will include product elements, numbered sketches and/or diagrams, quality control documents, for example all test information, operations, and maintenance directions, installation needs, and transportation needs for setting up to each site, and cost estimations. Design Specifications Client Network: The customer network transmits info between the customer and also the server. This is the way the customer may transmit and get info. The customer network generates a socket and it gets link to the server once the application begins. All the info which moves between the customer and the server passes through wrapper items. Each wrapper item has its own unique name having a unique name which identifies what's inside. Riordan will have their primary server and the backup host within San Jose. Each site has a shared thin client and application host. Client Manager: The customer administrator module is accountable for the connectivity between the GUI and networking element. The customer administrator serves as the middle device by altering info pulled from the customer GUI in a way where that info may be transmitted from one end to the network over the customer networking element. It handles this by placing the data in a wrapper classes, based on its objective. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 30 Server Manager: The server administrator module is called through the server network division and it is responsible for determining what must be done. The server administrator module decodes the wrapper item from the customer to confirm exactly what the client is requesting. Requests for info from the customer and queries of the customer byway of wrapper classes are additionally a function of the customer administrator. Server Network: The server network module is accountable for transmitting info between the customer and the server. For every customer link, the server network module generates a string which has an instance of the server administrator element. This string deals with all interaction for that customer. Final Design Models This report shall describe regarding the overall architecture of Riordan Manufacturing transactional system. All graphs and pictures presented are made using MS Visio. The main RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 31 objective is to show an advanced level representation of the ERP system and describe the communication with the world. The graphs shall also describe how each module in the ERP communicates with each other. System View System Flowchart RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 32 The system flowchart displays how each module communicates with the storage archive and the way they are linked with each other through these repositories. Statistical records are an essential part of it and bring managerial feel to it. Network Architecture RM ERP shall have central client server architecture. Customer may be an internal user spread out on LAN or WAN and an external user accessing the system via internet. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 33 Test Process Summary Checking is an iterative procedure happening at each phase of the integration of ERP performance. Module performance checking will decide if the inclusion of menu functions carries out as original design shows. Additionally system abilities are undergo a number of on line checking to make sure fields take and shift information to the database and show results to the user during statement creation. If latest releases are available the system manager will perform a practical check on a test system to guarantee the upgrade hasn't broke performance avoiding a break repair fall back on the production program. After Riordan's needs have undergone screening on the ERP system methods to complete following the golive date will include the subsequent to make sure system durability. RIORDAN: DEVELOPEMET OF AN ERP SYSTEM 34 Assess system efficiency according to information input, data storage, throughput, and reaction times on a weekly, monthly, and quarterly basis to find out system change. Creation of system reports from the difficulty administration system to gather metrics of typical issues that need handling in future loads. Help desk will establish functional and educational paperwork which includes checklist for preliminary problem solving and screening for flaws Setting up a Service Level Agreement (SLA) with the supplier as well as development organization will determine obligation for regular quality control as well as reaction time needs whenever system performance fails or doesn't work to Riordan's expectations. Fake accounts as well as test data will be produced to check the ERP systems capability to record stock items, items taken from stock, as well as monitoring of raw materials as well as finished production materials during every stage of the delivery procedure. Metrics will use test data to create metric reviews which are examined for efficiency of the ERP system design.
