Implementation Plan 3 Objectives and Goals Company X’s mission statement is to provide the community with quality products and service while maintaining a great relationship through charity and volunteering. The current goals for the organization are as follows: a. Increase customer base by 10% annually b. Increase orders by 5% monthly c. Transition from PBX to VoIP (Voice over IP) d. Add VPN solution e. Modernize the currant network architecture Each of the goals are aligned with critical success factors. These factors are activities performed to meet business or project goals that have been stated (Eby, 2023). To derive critical success factors our organization will need to align the project objectives with our corporate strategy, gain stakeholder consensus, hone in on essentials, identify risks, and lastly set metrics (Eby, 2023). The breakdown of these critical success factors is shown in the table below: Goal Critical Success Factors Increase customer base by 10% annually Increase customer awareness through website and marketing Increase orders by 5% monthly Increase sales to recurring customer and attract new customers. Transition from PBX to VoIP Transition from PBX system to the new Cisco Call Manager solution Add VPN solution Add and configure VPN solution to the network Modernize the currant network architecture Phase out end of life (EOL) equipment. Restructure network architecture design. Implement high throughput fiber optics. Table 1 Critical Success Factors

Implementation Plan 4 We need to also assess the variables associated to the success of the project. These variables are known as qualitive and quantitative. Qualitive variables are known as categorical variables. Their essence lies within representing distinct categories or classes rather than indicating a measurable quantity (Easily, 2023). Quantitative variables are known to be numerical variables, they represent quantities. They are used to provide measurable information thus allowing for a more rigorous and precise evaluation (Easily, 2023). The following table outlines these variables, which goals they align to, and their respective sources: Goal Measure Indicator (Qualitive/Quantitative) Source Increase customer base by 10% annually Change in baseline count of customers at annual audits (Quantitative) Customer satisfaction (Qualitative) Customer database Customer satisfaction survey Increase orders by 5% monthly Change in baseline sales revenue during monthly audits (Quantitative) Orders database Transition from PBX to VoIP New VoIP system is functioning (Quantitative) Network monitor/syslog Test data Add VPN solution New VPN system is functioning (Quantitative) Network monitor/syslog Test data Modernize the currant network architecture Equipment has been replaced (Quantitative) Network is operational (Quantitative) Network traffic baseline compared to upgraded equipment (Qualitative) Network monitor/syslog Test data Table 2 Qualitive/Quantitative Variables

Implementation Plan 6 latency. Implementing a three-tier network improves performance, management, redundancy, and scalability. It also allows us to shape traffic through the use of QOS (quality of service) policies. The network architecture portion of this project is critical. By completing this portion, we will enable the organization to meet most if not all the goals we have outlined. The upgraded architecture will be the foundation for not only allowing sales representatives to perform their job faster, but from any location that has access to the internet. This in turn will increase our customer base, which increases our sales revenues.

Implementation Plan 7 Network Reference Model Comparison (Week 2 IP) Current Network Reference Model OSI Reference Model One conceptual framework to network communications is known as Open Systems Interconnection (OSI) model. This framework divides network communication functions into seven layers. OSI is known for its ability to provide a universal language for computer networking, this is important due to the various hardware and software technologies that these systems are configured with ( What Is the OSI Model? - 7 OSI Layers Explained - AWS , n.d.). Each layer has their own specific technologies that provide a certain capability and perform specific functions ( What Is the OSI Model? - 7 OSI Layers Explained - AWS , n.d.). The seven layers of the OSI model are physical, data link, network, transport, session, presentation, and application. TCP/IP Reference Model Before the OSI model is the TCP/IP model, this model was developed in the 1960s by the Department of Defense (DoD) (GfG, 2023). TCP/IP stands for Transmission Control Protocol/Internet Protocol. Unlike the OSI model, this model only has four layers. The TCP/IP models’ main goal is to transfer data from one device to another through reliable packet delivery. TCP/IP only supports connection-oriented communication in which the OSI supports both

Implementation Plan 9 VoIP desktop system, and the upgraded network equipment. This solution will get rid of the outdated hubs currently used to connect all the end devices to the network. Current Data Flow Model The current data flow for a customer making a purchase order is simple. Customers come into the store to browse products. The next step is for the customer to place an order with one of the sales representatives. The sales representative inputs the data into the order to verify if items are in-stock or need to be ordered. If the item is in stock, the order is sent to the warehouse team to gather the items and prepare them for shipping. If the item is not in-stock, the warehouse team places an order with the suppliers to get the item to the warehouse. After the warehouse team

Implementation Plan 10 accomplishes their tasks, the shipping department takes over the process. They will inventory, process, and pack the product(s). Once complete, they ship the item(s) to the customer.

Implementation Plan 12 Revised Data Flow Model The main improvement is the addition of a company website. This website will allow customers to bypass the need for a sales representative for ordering products without completely cutting the representatives out. The goal is to shift their focus from current customers to reaching out and bringing in new customers to meet the 10% annual customer base increase and 5% monthly order increase.

Implementation Plan 15 Network Design Diagram (Week 3 IP) Current LAN Looking at the current local area network (LAN) by using the information provided by Matt (the information technology [IT] support person) our current network consists of an AS/400 mainframe, fifteen workstations, a router, several hubs to support three workgroups of five nodes each, a database, and a file server. This is the current diagram we have derived from this information. Reviewing this diagram, we can analyze the network architecture and identify some areas that need to be updated. Analyzing the three-hub connection on one port of the router can show

Implementation Plan 16 us the traffic and how it flows through this connection. One major concern with the use of hubs is that they function as one collision domain. Collision domain is a segment within a network that is shared but not bridged or switched; this can cause packets to collide as the bandwidth is shared by multiple devices (Gregg, 2006). Since hubs share bandwidth with multiple devices attached to them, this can not only cause collisions of packets but create a bottleneck due to reduced bandwidth. A bottleneck is an area or device in the network that limits the capacity or bandwidth flow between two or more devices (NordVPN, 2023).This current architecture has two collision domains which can be the cause to the intermittent internet access users are experiencing. Proposed LAN As part of our network overhaul, we will be ensuring the traffic has optimal data flow by using up-to-date equipment and replacing the hubs with layer two switches. This will increase our collision domains as each switch interface is considered its own collision domain (Popeskic, 2011). Once the new equipment is in place, we can continue troubleshooting with the ISP (Internet Service Provider) to resolve any further issues. The new network will add security features to support remote access for the sales representatives, a web server to increase our customer reach, a server rack with 3 Dell PowerEdge R650’s (file share, database, call manager, etc.), and Cisco C9300x series for the core and distro switches with C9300-48T access switches. This new configuration has VLANs (Virtual Local Area Networks) built in to add an extra layer of security and allow for QOS (Quality of Service) by prioritizing VLANs. The three-tier network architecture will allow for high-speed internal communications as the switches will be trunked using a 10Gbps fiber uplink between the layers. The server rack will also leverage the 10Gbps fiber uplink to the core switch, this will allow end-users the ability to pull information in

Implementation Plan 18 Goal Network Design Change Increase customer base by 10% annually Addition of a webserver to attract current and future customers Increase orders by 5% monthly Sales will naturally increase with the new customer base Transition from PBX to VoIP Removal of PBX system and installation of the new Call Manager Server to manage VoIP services Add VPN solution Addition of VPN gateway to allow sales representatives to access network resources from anywhere VPN software must be installed on remote user workstations to allow connection through the VPN Gateway Modernize the currant network architecture Legacy server and hubs are being replaced by state-of-the-art Dell R650 servers and Cisco 9300 Series switches, and the addition of a firewall for network security due to added web server and VPN

Implementation Plan 19 Telecommunications Plan (Week 4 IP) Goals and Objectives One of the goals that the owner has called for is the replacement of the old private branch exchange (PBX) into an update voice over IP (VoIP) and TCP/IP solution. The PBX offers users the ability to communicate both internally and externally using an internal telephone network. Features offered by PBX are in/outbound calls, call forwarding, voicemail, etc. The most common system related to PBS is known as Plain Old Telephone System (POTS), phones are connected to the network using RJ11’s with twisted pair wiring. This technology has not had any significant changes in the last 140 years (Doan, 2023). This system is meant to serve small businesses with a business phone system. The issue with the current PBX system is the excessive cost for a system that is not capable of the advanced features that IP phones provide. As part of the telecommunications plan, outlined in this section, we will look at the benefits and implementation of modern business telephone systems. The purpose of the telecommunications plan is to improve the company’s efficiency, productivity, and customer service by ensuring we have the proper communication tools at Company X (Linton, 2017). New Telecommunications Diagram This diagram will show the revised network diagram that focuses on the new telecommunications solution we have chosen for Company X.
