Implementation may also involve the creation of an object-oriented database. List and describe the steps in the prototyping process. P art IV shows how to use the knowledge acquired in earlier chapters to analyze and design information system solutions to. Headquartered in Seoul, South Korea, this company manufactures and sells petrochemical products, such as synthetic resins, synthetic industrial materials, such as ethylene glycol and ethylene oxide for making polyester, automobile antifreeze solutions, benzene, propylene, and ethylene. The list was cut to a more manageable size and the executives were asked if there were any additional reports or data from which their organizational groups could benefit. Structured methodologies are top-down, progressing from the highest, most abstract level to the lowest level of detail—from the general to the specific.
Its goal is to provide low-cost travel along with unique amenities like TV in every seat, and its development of state-of-the-art IT throughout the business was a critical factor in achieving that goal. The company began with approximately 40 employees and three aircraft. Interactions between the system and its users are analyzed to identify objects, which include both data and processes. The software for its Dealer Business System DBS , which it licenses to its dealers to help them run their businesses, is becoming outdated. The direct cutover strategy replaces. How does Scrum differ from other software development methodologies?
Component-Based Development, Web Services, and Cloud-Based Development To jetb,ue expedite software creation, groups of objects have been assembled into software components for common functions, such as a graphical user interface or online ordering capability, and these components can be combined to create large-scale business applica- tions.
Tasks in one stage are supposed to be completed before work for the next stage begins. What people, organizational, and technological factors contributed to the problem?
A Tale of Two IS Projects In recent years, the airline industry has seen several low-cost, high-efficiency carriers rise to prominence using a recipe of extremely competitive fares and outstanding customer service.
JetBlue had the advantage of seeing WestJet begin its implementation months before, so it was able to avoid many of the pitfalls that WestJet endured. What alternative jetglue are possible for achieving these objectives and meeting these information requirements?
The systems analysis includes a feasibility study to determine whether each proposed solution is feasible, or achievable, from pprojects financial, technical, and organizational standpoint. Because objects are reusable, object-oriented development could potentially reduce the time and cost of writing software if organizations reuse software objects that have already been created as building blocks for other applications.
From a customer perspective, only one of two things can happen: Large projects benefit from appropriate use of formal planning and tools for document- ing and monitoring project plans. This last ttwo was the most feasible for the Girl Scouts. What information is required to achieve fo objectives? These problems impact both of the airlines operational activities and decision making to change their initial carrier which had started out as a system designed for smaller start-up airlines to a better carrier.

These alternative methods include the traditional systems lifecycle, prototyping, end-user development, application software packages, and outsourcing. Intangible benefits, such as more efficient customer service or enhanced decision making, cannot be immediately quantified.
Members of the organization must agree that a problem actually exists and that it is serious.
They also wanted access via the Web or their mobile devices. The project described here is a data administration project.

The company began with approximately 40 employees and three aircraft. As you read questiond case, observe how Honam handled these problem-solving activities: The Scouts rely on volunteers with little or no business or computer experience for sales and management of orders and deliveries.
It also serves as yet another reminder of how successfully planning for and implementing new technology is just as valuable as the technology itself. Quality is an indicator of how well the end result of a project satisfies the objectives specified by management.

During this stage, users and technical specialists review the solution to determine how well it has met its original objectives and to decide whether any revisions or modifications are in order. The systems analysis lays out the most likely paths to follow given the nature of the problem. Managing the Change Developing a new information systems solution is not merely a matter of installing hardware and software. Larger companies or business owners with jetbule experience use these software development kits to wstjet apps from scratch.
The system enables them to view key per- formance information such as manufacturing costs by plant, transportation costs, daily production and inventory rates, and global product price trends, and the information can be displayed visually in dash- boards and management cockpits. Classes of objects in turn inherit all casd structure and behaviors of a more general class and then add variables and behaviors unique to each object.
Do managers have sufficient information for decision making? When WestJet went live with the new system in Octobercustomers struggled to place projets, and the WestJet Web site crashed repeatedly.

The system builder notes all changes the user requests and refines the prototype accordingly. The lifecycle methodology is a phased approach to building a system, dividing systems development into questioons series of formal stages, as illustrated in Figure The object-oriented design phase describes how the objects will behave and how they will interact with one other.
The level of project risk is influenced by project size, project structure, and the level of technical expertise of the information projecs staff and project team.
If the quextions is working with a new technology, is using a new development methodology, or even if there are new, relatively unknown team members, these need to be listed as potential risks to the project. What are some of its other design speci- fications?
