Chapter 1: Business Information Systems in Your Career
Case 1: UPS Global Operations with the DIAD
1. List the various ways that DIAD improves customer service.
Faster pickup and delivery schedules. Real-time tracking of packages based on bar code technology, and using Wi-Fi and cellular connections; a local Bluetooth network to connect the driver with the truck. GPS built into the unit to help drivers locate delivery and ...view middle of the document...
4. Why doesn’t UPS use much more powerful and smaller smartphones like the iPhone or Android?
The DIAD units are much more robust than consumer smartphones and can withstand larger drops, rain and intermittent submersion, and other abuse. While many features of the DIAD are also available on smartphones, the DIAD is optimized for these features (like scanning barcodes, using multiple cellular carriers) whereas ordinary smartphones are not.
5. Why is the DIAD V better than the DIAD IV?
Improvements that employees mentioned in the video are:
• Quick response times
• Strap to hold DIAD while holding other packages
• Reduced size and weight (1.5lb (compared to about 5 lb.)
• Easier to handle, one-hand operation
• Illuminated screen to use at nighttime
• Better signature writing feature
• Easier interface for typing
• Improved scanner beam performance for scanning barcodes
6. How does UPS’s investment in IT help it achieve the strategic business objectives described in Chapter 1?
The most important contributions of technology to UPS strategic objectives is the greatly enhanced operational efficiency; the compression of time to deliver; the development of new services like tracking, and overnight or 2-day service; the closeness to the customer; improvements in the quality and speed of decisions related to packages.
Firms that made these investments in IT benefit by achieving significant competitive advantage over others in the package delivery business. FedEx remains a much smaller but competitive service especially in the overnight market. Other competitors have largely disappeared.
Case 2 Google Data Center Efficiency Best Practices
1. What is PUE, and why is it an important place to start when considering how to reduce data center power consumption? What value of PUE should data center managers strive for?
PUE stands for power usage effectiveness, measured as the ratio of total facility energy divided by IT equipment energy (watts). IT equipment refers literally to the computers and hard drives used in the facility. Total facility power would include lighting, and cooling. In 2006, a typical data center would consume 2 watts of total facility power to support 1 watt of IT equipment. Today the number is much closer to 1.10 because of changes in IT equipment, and changes in facility power management. The ideal is a PUE of 1, in which case all power was being used to simply operate the IT equipment and no other significant support power was being used.
2. Describe the five methods recommended by Google for reducing power consumption.
Measure the PUE is the first step. If you can’t measure efficiency, you can’t manage it. Second, manage airflow by isolating cool aisles from hot aisles, and preventing the premature mixing of hot and cold air. Third, adjust the thermostat up to operate the IT equipment at a...
