...are the inputs, processing, and outputs of UPS’s package tracking system? The company’s inputs are: package information, customer signature, pickup, delivery and timecard data, data location and billing and customer clearance documentation. Processing: They simply transmit data into the central network. The driver places the DIAD into the UPS truck’s vehicle adapter then the package tracking information is then transmitted to UPS’s network for storage and processing in the main computers. From there, the information can be accessed worldwide to provide proof of delivery to customer. The scanning of the barcode at various points along the route and the data is fed into the central computer to keep track of the progress of shipment. Output: the delivery information that can be assessed worldwide to provide proof of delivery to customers.

...keep customers satisfied, and competitors on their toes. In the past 10 years FedEx has made much progress in automating many of their information systems such as invoicing and accounts receivable. They also led the industry in providing online services to their customers, and high-speed mobile devices to their couriers. One of their most notable technological advances was their development of DirectLink. FedEx created DirectLink, a powerful electronic data interchange (EDI) enabling software, to allow customers to download invoices, create reports, export data, and remit payments. Customers can still pay their bills online, over the phone or the traditional way by mailing in payments; however, FedEx encourages customers to sign up for DirectLink because of many advantages it offers (FedEx, n.d.a). DirectLink allows customers to download bills, remit payments online and manage their own account, which is extremely efficient for the customers and the company. For one, electronic invoicing allows FedEx to save money on printing and postage costs. Electronic payments also save time and create less manual work for the company. The AIS validates records and processes payments. With the AIS processing payments, it eliminates the chance of human input error; it also prevents returned check fees. Allowing customers to manage their own account also saves money on call center costs. When customers have questions about their account they can go online and look at...

...UPS CASE STUDY For UPS to operate as immaculately as it does it takes advantage of a system that has taken many years and billions of dollars to develop. It all starts with the package labeling. For each package a label is given. On the label are a barcode and a number. On the barcode UPS inputs important information about the sender, destination, and estimated arrival time. UPS uses this information to process its packages. With its automated tracking system UPS can monitor the delivery process and even re-route packages if needed. Periodically through the life cycle of a delivery barcode devices scan shipping information on the package labels to update milestones in the delivery status. Customer reps can use this information to update customers on where their package is. Customers also have the option to check themselves vi a the UPS website or mobile app. UPS utilizes a myriad of technology to insure its success. One of the most important is its Delivery Information Acquisition Device (DIAD). This is the everyday device that uploads to a wireless network and gives its drivers instructions for the day. It also captures customers’ signatures and automatically updates tracking information in the UPS system for processing and storage. From the beginning UPS promised “the best service and the lowest rate.” UPS works hard to deliver on this commitment. Going back to UPS’s label system information is sent to one of its computer centers before the package is even picked up. This...

...They have hubs located in St. Louis, Bayonne N.J, and in Los Angeles. Huffman’s trucking has a fleet of 800 trucks. Each truck is equipped with a GPS tracking system. This allows each truck and it’s cargo to be tracked to and from its destination. The dispatch is vital to operations, by allowing the truck and cargo to be tracked, and monitored. The companies driver’s are tracked from the moment he and his freight leave the warehouse. It also allows for real time access. Without real time access, remote locations would not be able to access the specific data on the trucks, in real time. Each truck is connected to the system through the real time access. Keeping these systems up to date will increase the speed of delivery and information. Each truck is equipped with a GPS system that is connected to the hub. Each hub has specific information, on all trucks and freight. This way the company knows which trucks are carrying which freight and going to which destination. Without exact locations of each truck, shipments can get lost or misplaced. Without this information system, the company could get back logged and need to sort out everything. This is very important to keep the costs down. The company would have to conduct a manual search and and therefore end up being more costly. They would have to contact each driver and go...

Also what is the weight and size of components being delivered and scheduled time of delivery. Equipment – Equipment would have the same fields as booth components except need tracking system to now where is equipment is located and in what order each piece of equipment will be showcased. Shipments – Shippers name, address, and contact information, shipment warranty information, scheduled delivery and pickup times. Something that is contained on our shipment boxes is how many pieces are being shipped and how to handle equipment because some electronic equipment needs to be handled with care. Example of two relationships that need to be tracked. The first relationship that needs to be tracked is between the shippers and equipment being shipped. Marketing assistant needs to keep track of shipping information to determine when shipment will arrive and to coordinate movement of equipment. The second relationship that needs to be tracked is between personnel that supervised the set up and breakdown and booth components. In order to account for booth components the marketing assistant needs to know who to contact for each component, especially if any issues arise. ...

...[March 5th, 2010] [pic] | Rebecca Murphy, Reginald Demery and Melanie Bennett | Kudler Fine Foods is a small franchise of three stores currently. Each store provides the quality of service you would expect from a specialty store. Even though small in size the product selection is large. The current operating system each store has needs to be upgraded. All stores should run the same equipment requirements and software. Initially there would be cost involved for the upgrade but it is definitely a well worth investment to improve sales inside the stores and online. Adding the feature of ordering online would boost sales. Kathy Kudler would be able to create this online ordering site from within the current site or she could bring someone in to create it. Again it would be a well worth investment. Kudler Fine Foods is an amazing company but the website lacks information and customer satisfaction. When a customer visits the Kudler Fine Foods website we want them to experience the very best customer service while allowing them to want to revisit. We have to improve a lot of problems with the Kudler Fine Foods website to better help our customers and in order to do that we are going to improve the websites appearance, improve communication, which will include a 1-800 number for customers if they have a problem, create a FAQ page/email and most importantly...

...plan that fits her budget in this economy is going to be tough but is very manageable. If you look at businesses in the market, then one should know that a business should be able to adapt to change and provide a service that is fast and reliable. We are going to be taking my sisters manual tracking and ordering system to an updated automated system. In order to make her store automated we will have to go on a shopping spree and purchase the hardware for the automated inventory system. Since we are on a budget we will look at the main things that will be needed. Hardware is a major part of automating her business. Hardware consist of a computer or laptop, an operating system, keyboard, router, mouse, and external hardware (i.e. printer, fax, and copier). My assumption is that she does not have any of this so we are starting from scratch. After purchasing and setting up the hardware she will need we will move on to the next step, Software upgrades and requirements. Software can be simple or it can be complicated. It can also be costly if you are not careful. If we go with the more expensive route we would need to invest in scanners. Investing in scanners will be necessary to keep up with the products coming in and out of store. Software can be complicated and become a very touchy subject. We could pay a third party to write a program for the store specifically or we could buy one that is already packaged. Benefits of having one made for the store consist of allowing you to...
