Title: Consolidated Messengers
The following Case will present a Consolidated Messengers followed by 12 questions. You will have 25 minutes to complete the Case.
For help on how to answer the questions, click the Instuctions button on the question screen. Consolidated Messengers
Consolidated Messenger is a shipping company that specializes in overnight parcel delivery. The company serves North America and Europe, and it provides both ground and air services. For delivery, the company uses its own vehicles, which includes trucks and aircraft. The company handles an average of 100,000 parcels every week. One of its most important services is business­to­business delivery.
Because the shipping market is declining, the company often sends out vehicles that are less than completely full. To maximize the use of space in its vehicles and to increase revenue, the company wants to offer a new service to independent transportation brokers. The new service will enable the independent brokers to use the company’s vehicles to send large shipments between cities. Each shipment will consist of a large number of parcels. The company’s existing business applications must be enhanced to support the new service.
You are a developer employed by Consolidated Messenger. You will lead the development of a solution that uses the Microsoft .NET Framework to meet the requirements of the new service.
Existing IT Environment Existing Applications:
The company uses a parcel­tracking application that runs on a Microsoft Windows 2000 Server platform. This application has interfaces to client computers, handheld PCs and the Internet. Company employees use client computers and handheld PCs to track the movement of parcels. Customers use the Internet to track the shipping status of their parcels.
For each parcel, the existing application tracks the following information:
Waybill number
Account number to change
Terms of payment
Sender name
Sender address
Sender telephone number
Recipient name
Recipient address
Recipient telephone number
Current shipping status
Users do not need to be authenticated to check the status of a waybill.
History records are maintained to track the location of parcels. A history record is written each time a parcel changes location. A history record contains the following information:
Waybill number
Route number
Depot number
Current shipping status
The average parcel requires 1KB of storage space for the parcel information and all associated parcel history records.
The company also uses a vehicle­scheduling application to track vehicles and their routes. This application schedules routes between depots, tracks the availability of vehicles and assigns available vehicles to scheduled routes.
The vehicle­scheduling application uses its own database, which includes the following tables:
The Route Definition table describes the characteristics of valid routes between depots, including scheduled departure time and arrival
The Vehicle table records the type and size of the vehicle and its availability status
The Route instance table associates a specific vehicle with a defined route. Every time a vehicle transports a shipment between two depots, an entry in the Route Instance table is created Physical Implementation:
The parcel­tracking application and the vehicle­scheduling application were developed by using Microsoft SQL Server 2000, ASP pages, COM+ components written in Microsoft Visual Basic 6 and client software written in Visual Basic 6. The parcel­tracking database is currently 1 terabyte in size.
The company operates a private network that spans two continents. Its public Web servers run on a separate network and are protected by a firewall.
As a company standard, Consolidated Messenger uses Windows 200 Server computers and a SQL Server 2000 database management system. The company plans to use the Microsoft .NET Framework for new applications and for significant enhancements of existing applications. Interviews IT Department IT Manager:
The new enhancements must be integrated with the existing parcel­tracking and vehicle­scheduling applications. An online registration process must be available to the independent brokers so they can request access to these applications. Once they are registered, the brokers must be properly authenticated for security purposes. We also want to be able to track the revenue associated with each broker. We are not planning to add any additional staff to develop or support the enhancements.
Business Stakeholders Vice President of Operations:
Currently, depot managers report that our vehicles are not being used to capacity. The existing vehicle­scheduling application does not track the amount of space that is being used on each vehicle at a given time. However, the new solution should enable us to track this information. This enhancement will
help us manage our vehicles more efficiently.
To handle the anticipated volume of new shipments, my department needs to know the pickup depot, the dimensions and the weight of each shipment.
The new solution must include an interface for independent brokers. These brokers must be able to use the Internet to schedule their own shipments. Brokers usually comply with strict time constraints. If
response time is slow, they will not use our services. To keep our costs low, each broker must be able to track its own shipments. However, no broker must be permitted to see information about the shipments of any other broker. We also want to be able to track the amount of business that each broker gives us over a period of time.
Requests for the new service will be fulfilled in the order in which they are received. When no vehicles are available, independent shipments must wait until the next day. However, all independent shipments must be completed in three days.
Finance Department Chief Financial Officer:
Company revenue and profit margins are declining. The new service is extremely important to our financial outlook. My forecast shows a 20 percent increase in the number of parcels delivered during the first year of the new service and a similar increase in each subsequent year. We can handle this additional
volume by using our existing vehicles more effectively. However, the new solution must be capable of scaling to meet the continuously increasing demand.
Users Depot Manager:
My staff is comfortable with the existing parcel­tracking application. I want the new solution to be well integrated with this application so the staff does not need to learn a new interface. I also want to ensure that our existing handheld PCs and bar code readers can be used to track shipments.
Response time for the bar code readers must be fast enough to handle the new shipping volume, without any errors. Response time for the vehicle­scheduling application must also be fast. Delays in updates can delay a shipment or reduce the amount of space used on a vehicle.
The current parcel­tracking application tracks only the weight of a parcel, not its dimensions. To ensure that space is fully used on each of our vehicles, my staff will need to know the dimension of each parcel, expressed in terms of height, length and width.
Business Process Vehicle Scheduling:
Currently, Consolidated Messenger operates a fleet of 200 aircraft and 600 trucks. Vehicles operate in all major markets served by the company. Vehicles are scheduled one month in advance on the basis of anticipated demand. One master schedule is in effect Monday through Friday. Each weekday follows the same timetable. Saturday uses a different schedule. No deliveries occur on Sunday.
The master schedule indicates the type and size of the vehicles needed to meet delivery requirements for the week. Available vehicles are associated with a scheduled route to form an active route. In total, the company’s vehicles complete approximately 3000 routes each week.
Parcel Tracking:
Currently, each parcel is assigned a waybill number when it is picked up. A waybill bar code is affixed to the parcel. This bar code is scanned at various checkpoints in the shipment process. A typical delivery includes the following checkpoints Picked up Received at depot On delivery truck Delivered
Customers can query the status of their shipment by using a Web browser. Response time to the customer is not critical, as long as this response is faster than telephoning a customer service representative.
