CHAPTER 12 CASE STUDY: LIFE ON THE GRID: iPhone BECOME iTrack

1. Why do cell phone manufacturers (Apple, Google, and BlackBerry) want to track where their customers go?
Cell phone manufacturers, Apple, Google and Blackberry, want to track where their customers go due to various factors. Firstly, location-based service provided in Apple, Google’s Android and BlackBerry smart phones can be the tool for three of the cell phone manufacturers to earn money. They can earn money by the location-based service in smart phones through advertising. Apple and Google are advertising platforms, so this makes them create the location-based service in their smart phones products.
This can be explained that mobile technologies based on the smart phone make it possible to locate people who use smart phones. After that, the location data of the users will be reported to the smart phone manufacturing company databases, retained and analyzed. The analyzed location data will then be sold to advertisers and others. When the advertising firms received the location data of their customers, they will pay Apple, Google’s Android and BlackBerry for the information of their customers’ location and for the distributing of their mobile advertisements. Once the advertising firms know where their customers are through mobile, they can send the customers advertisements, coupons, and flash bargains based on where the customers are.
Next, Apple, Google and BlackBerry needs the location data of their smart phones’ users as they want to use the information to identify the location of cell phones for WIFI connected phones, and to improve the customer experience of location based services. Furthermore, the location information of users is also needed for them to improve their services.
Moreover, location-based service created in smart phone can also build a strong and closed customer relationship to Apple, Google and BlackBerry. For instance, Foursquare, a 2009 start-up, is a popular mobile social application that allows users to check in to a restaurant or other location, and the app automatically lets friends on Facebook and other programs learn where you are. After starting up Foursquare on a smart phone, smart phone users will see a list of local bars and restaurants based on their cell phones’ GPS position. Foursquare has a widely accepted loyalty program. Each check-in awards users points and badges, which can be used later for discounts and at various venues. Users of smart phones with Foursquare app are also awarded to be “Mayors” of the venue based on how many times they have checked in over a month’s time. Those who become Mayors will be given special offers. Thus, from here, it is shown that Apple, Google’s Android and BlackBerry provide location-based service in their smart phones can help them to create customers’ values.
2. Do you think cell phone customers should be able to turn tracking off? Should customers be informed when they are being tracked? Why or why not?
In my opinion, I think that the cell phone customers should be able to turn tracking off. They should also be informed when they are being tracked. This is because if the systems of the smartphones manufacturers do not have the action of that, they will violate their customers’ privacy for certain scenarios. For example, it is sure that most of the people do not like others from the public, who they do not know, to have known their location and what they are doing. This will be especially when they are enjoying their special occasions, such as, wedding ceremony and dating. So, from here, it is encouraged that customers are informed when they are being tracked.
Moreover, allowing smart phones users to turn tracking off using their smart phones’ functions also acts as a respect of the cell phone manufactures towards their customers. They can show their respect to their customers by giving permission to their customers to choose to check in their location areas or not through their phones’ location-based services.
Last but not least, if there is no awareness of being tracked among customers and customers cannot turn tracking off, users will be scary to use smartphones with location-based services. This may bring bad reputation to the cell phone manufactures and also the smart phones products itself. It is owing to the bad treatment and customers’ services provided by the system of cell phones. Consequently, sales of cell phones with location-based services may decrease.
3. Do you think cell phone tracking is a violation of a person’s privacy?

Many privacy groups are calling for legislation to gain user consent as a condition of cell phone tracking. Go to the Internet to find out one of the privacy groups and summarize its stand and viewpoint. We must support this group in its call for federal regulation cell phone tracking. Because the Cell phone manufacturers (Apple, Google and Blackberry) tracking is indeed an invasion of privacy. A privacy group is Electronic Privacy Information Center (EPIC).The Electronic Privacy Information Center (EPIC) was founded in 1993 and focuses public attention to emerging civil liberties and to protect privacy, the first amendment, and constitutional values. EPIC does not lobby for, consult, or advice companies, nor do we endorse specific products or services. This list merely serves as a sampling of available privacy-enhancing tools. I do support its calls for federal regulation because it does need to be regulated, as this type of tracking is a breach of privacy. Google and Apples position of cell phone tracking is to help improve apps and service. Limitations of cell phone tracking can be specified in the settings from accurate to city locations.

CHAPTER 11 CASE STUDY: DST SYSTEMS SCORES WITH SCRUM AND APPLICATION LIFECYCLE MANAGEMENT

1. What were some of the problems with DST Systems’ old software development environment?
DST Systems is a software development company whose flagship product, Automated Work Distributor, increases back – office efficiency and help offices become paperless. DST was founded in 1969 and its headquarters are in Kansas City, Missouri. The company has approximately ten thousand employees, 1200 of whom are software developers.
Some of the problem is DST Systems’ used a mixture of tools, processes, and sourced code control system, different group within the organization used very different tools for software development for example like Eclipse. This makes managers hard to unable to easily determine how resources were being allocated, which of their employees were working on certain project, and the status of specific assets. Another point is the previous method that is “waterfall” method which is used for designing, coding, testing and integrating its product. In the waterfall model of software development, progression flows sequentially from one step to next like a waterfall, with each step unable to start until the previous step has been completed.
2. How did Scrum development help solve some of those problems?
Scrum is a framework for agile software development in which project progress via a series of iteration called sprints. Scrum projects make progress in a series of sprints, which are time boxed iterations no more than a month long. Scrum development help solve some of those problem by relies on self- organizing, cross- functional teams supported by a Scrum Master and a product owner. The Scrum Master acts as a coach for the team, while the product owner represents the business, customers or users in guiding the team toward building the right product. DST tried Scrum with its existing software development tools and experienced strong results. The company accelerated its software development cycle from 24 to 6 month and developer productivity increased 20 present.
3. What other adjustments did DST make to be able to use Scrum more effectively in its software projects? What management, organization and technology issues had to be addressed?
The other adjustments DST was able to make to use Scrum more effectively in its software projects were by setting up a project evaluation team to identify the right development environment. DST wanted the ability to use the new software without significant training and software they could quickly adopt without jeopardizing AWD’s development cycle. After considering, DST settled on CollabNet’s offerings.
CollabNet specializes in software designed to work well with agile software development methods such as Scrum. Its core product is TeamForge, it used to centralize management of users, projects, processes and assets. DST adopted Collabnet's subversion product to help with the management control of changes to project documents, programs, and other information stored as computer files. DST’s adoption of CollabNet’s products was fast, just requiring 10 weeks. Besides, the adjustment allowed DST to complete all of their work within the ALM platform.
For the part of management, organization and technology issues had to be addressed, Jerry Tubbs, the systems development manager at DST systems, says DST was successful in attempts to revamp the software group because some factors.
1.Looked for simplicity rather than complicated
2.Much cheaper than some of the alternatives
3.Involved developers in the decision making process to ensure that change to be greeted enthusiastically
4.Allow for the developers to adopt ALM software on their own
The company was successful because they selected the right development framework as well as the right software to make that change a reality and skillfully managed the change process.
