The company currently has three store locations, two in Michigan, one in Ohio and within proximity to each other and the Michigan-Ohio border. There are roughly 50 staff members employed at the company that ranges from cashiers, stock-warehousing, accounting, IT, leadership, marketingsales, and various other roles. The company has been around for four years now establishing themselves as a better brand of a general store with higher quality food-items; with a focus on maintaining a clean and safe store for all customers. In those years the company grew, learned more about the customer base, established capital and is now poised for expansion. The franchise owner and founder, Mr. Davis is looking to double down and open three new locations across the Lake Eric into Pennsylvania. There has been a strong presence of customer loyalty, in where the patron is willing to pay a more for a better quality item and overall store experience. Strategic analysis done shows great potential in the mid-west market and now is the time for expansion. Total functionality of operations from purchasing, inventory, asset management, employee engagement onto most business workflows is smooth throughout the company. There is a glaring issue preset which the owner, CFO, CEO, and managers all agree on needs to be addressed. Each store operation runs well, but they are running in isolation from each other, in that, there is no cross-communication or unified platform, in a sense they are silos to each other. This has sustained for some time now and has worn on the external departments that keep books, 2 Networking & Telecommunications IT640-1901B-01 inventory, and data consistency. American Trading Post is a company that focused more on the goods and services to the customer while solidifying a brand and market niche. Leadership now wants to bring store technology up to speed in various areas to be competitive and begin to tie in all current and new sites into one enterprise system architecture. If ATP wants to expand and continue its success, it will need to umbrella the stores, secure systems, set standards, and position themselves for growth. Corporate leadership is behind this mission statement. Even though each store has decent infrastructure that provides well for the site but systems, databases, security, inventory, etc. The data is scattered through various apps, servers, and networks. Goals & Success Factors The owner, Mr. Davis sat down with key staff members and a consultant group to determine the scope, goals, and factors for success for unifying the store's networks. Seen below for the high-level overview carved out by this group: Objective / Goal Establish a unified network between all stores. Centralized Applications & Systems Build out three new stores 3 Measure Indicator Quantitative = physical equipment, infrastructure, switches, cabling. Qualitative = fluid connectivity from any store; phones, registers, domain, communications Quantitative = Servers builds the business standard for applications, and creation of an ECM or repository.

Qualitative = survey, polls, advertising, Staff/Customer usage of systems and perceived quality of life Quantitative = Accounting dept., operating costs, simply net earnings minus the cost of goods. Marketing, sales, and image research, product & service. Assets, Inventory, Sales, integrated systems & apps. Infrastructure The following areas call out the American Trading Post stores and provide an analysis as to how the project aims to fulfill the mission statement. It will review what the current network supports along with the stated business goals and objectives. Also touching on each of the networking problems that each of the store managers has concern for. Current State As previously stated there are three store locations: the founders' site, store number two is located in Michigan, and store number 3 in Ohio. The original store #1 has plenty of space and would be perceived to be the model store for other branch locations although some of its technologies for examples phones, kiosk, registers are due for an update. This location brings in a lot of revenue, constant foot traffic, has a huge and growing customer base with a moderate technology footprint. Store #2 is in a prime location for customers, shares plaza space with other businesses, and is relatively smaller compared to the rest. It varies from low to high on systems technology it can use given location and hardware onsite. Store #3 is a moderately spaced facility built in the last ten years where ATP is recently bought after the lease was up a year ago. Since then new hardware, appliances, and infrastructure have been put in place. 4 Networking & Telecommunications IT640-1901B-01 Broken State ATP’s founder's site (store #1) is estimated needing to bring almost 50% of the hardware up to date to be stable. Requests to look into upgrading telecommunications which are outdated, address bad overhead paging, along with most registers which fall out of contract next year. There are security system & camera gaps that shift managers have mentioned. Store #2 has been having issues with the shared business lines for internet and telecommunications, as well, face limitations on space, mounting, power, and even cooling for most any device. Lastly, Store #3 has good technologic posture for the network, system, app, telecom, and the like. Managers find what’s broken is compliance, sloppy work, and no foresight for monitoring, security, or any form of pro-activeness. What’s broke is staff training/encouragement and capitalizing on all features, licensing, functions each system or service provided. This site should be a model for next-gen firewalls, cloud, and various other new equipment put in place. Future State The ATP founders site is an ideal location to establish a main data center and center for SDWAN connections given space. In a typical SD-WAN scenario, branch store broadband would connect directly to the public Internet. However, in today’s world “with heightened security and compliance responsibilities, traffic from the branches is backhauled over an encrypted VPN to internal gateways, where a third-party security services provider monitors all traffic and enforces security policies.” (Network World, 2018). This company will need to look hard at cloud solutions for apps, software as a service, portal hosting, and even outsourcing the datacenter. There is a plethora of solutions that fit any business for any budget nowadays. Store #2 the shared business lines for internet and telecommunications will need to be addressed and new answers sought out. Space being at a premium alternative like Citrix portals or client VPNs can 5 Networking & Telecommunications IT640-1901B-01 allow some staff to work offsite. Leading to cost or space savings “Once an organization decides to support work from home, there is an opportunity to reduce costs for the following: rental space or purchase of office buildings, desks, and furniture, desktop computers and monitors, telecommunication routers and connections” (M.U.S.E 2019). Another consideration moving forward is that many patrons have been asking about guest wireless in and just outside the store; even ATP staff could benefit from this if setup correctly. Store #3 should be seized as a model location and possibly looked at for trail of new hardware, products, and even software. The good news for the future state of things is the owner, and varied staff sees the necessity for investment and monies for this can be allocated. The CFO and accounting have a more conservative mindset and are researching different models for cost and methods for payment. Discussions overpaying in full, leasing, or how long to keep/depreciate IT assets are becoming more frequent. New technology is not cheap to nor is the configuration and staff to manage it, but there is true ROI baked in and allows the business to stay competitive. 6 Networking & Telecommunications IT640-1901B-01 Network Reference Model Comparison (Week 2) It has come to the attend of leadership that there is no consistent or reliable documentation throughout the locations. Though staff is equipped to explain the functions, workflow, and all the steps involved for each of the keys areas of business. It’s important to take note the company is running in a dual-stack environment but is feeling the effects of memory usage to the avail of application impacts. OSI and TCP/IP References Given the factors mentioned and to get grounded on tasks of ahead of the business a reference model was created for devices, applications, hardware, and software currently (fig.1) and a revised (fig.2).

With workflow mapping, the business can map out the steps for flows to better understand, evaluate, and improve them. Having this roadmap helps the ATP have more insight to business processes, identify redundancies, increase accountability, reduce micromanagement, improve communication, provide better customer service, and better quality for the goods or services (Tallyfy, 2018). Thus meeting key goals for an update infrastructure and establishing a unified network between all stores.

Retrieved from: https://tallyfy.com/why-workflow-is-important/ 18 Unit 1 Individual Project The retail store has hired you to assist in resolving the recent networking problems that have been occurring. The new owner needs you to address the issues so that his company can accomplish its mission and goals. He thinks that the network needs to expand (or at least be fixed), but at this point, he has no idea what the current network has or what it needs. The owner needs you to assess the current network, come up with some conclusions about next steps, and report the results to him. He wants to make sure that you have a good understanding of his goals and objectives as well as the presenting problems. You have been asked to develop a solution in the form of a Network Design and Implementation Plan for your retail store. The project deliverables for this week are as follows: • Network Architecture Assessment (4–5 pages) o Describe the general business environment for the case study organization. o Include a network goals and objectives statement. o Include a narrative that provides an assessment about the general current state of the network architecture. o Include a narrative that details your conclusions about the extent to which the current network supports the stated business goals and objectives. o Include a narrative that articulates each of the networking problems that the owner has presented. o Provide an analysis as to how this part of the project fulfills the mission and 1 or more goals of the case study organization. Unit 2 Individual Project The retail store has informed you that no documentation of the current network exists. There are numerous types of data communications that occur in a retail company, and the employees are willing to explain to you what information they work with and the steps that are involved to process the daily business transaction paperwork. Assume that the retail store is currently using open systems interconnection (OSI) and transmission control protocol/Internet protocol (TCP/IP) in a dual-stacked environment. This has proven to be memory-intensive and has caused an inability for application internetworking to occur. The project deliverables for this week are as follows: • • • • Create a network reference model diagram of the current network that describes the role of each layer for both OSI and TCP/IP that are used to transmit data between the devices and applications specifically in your retail store. Create a revised network reference model diagram of the proposed network solution (using OSI or TCP/IP) that describes the hardware and software that are used to transmit data between the devices and applications in your retail stores. Based on the current dual-stacked network environment, create a data flow diagram for both OSI and TCP/IP that shows at least 4 typical network connections that are made by users in your retail store. Show how the data and information flow from the user workstation to the application using both the OSI and TCP/IP network models and the impact of encapsulation. Create a revised data flow diagram based on the proposed network solution that shows at least 4 typical network connections that are made by users in your retail store. Show how • • • the data and information flow from the user workstation to the application using the chosen network model (using OSI or TCP/IP) and the impact of encapsulation. Provide an analysis as to how this part of the project fulfills the mission and 1 or more goals of the case study organization. Note: Use Microsoft Visio or equivalent to create the network reference model (current and revised) and data flow (current and revised) diagrams. You will embed the diagrams in the Word document and also provide them as attachments. See your Web resources for additional diagramming tools. All sources should be cited both in-text and in References using APA format. Unit 3 Individual Project The retail store knows that the current network model is not reliable, and the idea of adding a Web server to host its Web site seems unfeasible. To the best of his ability, Matt (the information technology [IT] support person) has shared with you that there is an AS/400 mainframe, 15 workstations, a router, several hubs to support 3 workgroups of 5 nodes each, a database, and a file server. It is hoped that the company will grow and that it will need to hire more employees in the near future. Internet access is sporadic, but it is supposed to work (according to the cable company). The project deliverables for this week are as follows: • • • • • Create a local area network (LAN) design diagram of the current network that describes the hardware and software resources that Matt described. Create a revised LAN design diagram of your proposed network that describes the hardware and software resources that you recommend be implemented. o Provide a rationale for your network design. In support of your revised LAN diagram, provide a specific narrative that details the specific changes that you are recommending and why you feel that those changes should be made. Provide an analysis as to how this part of the project fulfills the mission and 1 or more goals of the case study organization. Note: Use Microsoft Visio or equivalent to create the LAN design diagrams (current and revised). You will embed the diagrams in the Word document and also provide them as attachments.
