CASE STUDY CHURCH INFORMATION SYSTEM XYZ Church is a fast-growing church in Grand Rapids area. Over the past three years, since the popular Reverend Timothy Becker has taken over leadership of the congregation, the church has more than doubled in size. It now has approximately 400 registered households. Reverend John Howard has also recently been added as a second minister. Since the Church was rather small in the past, most of its records have been kept on paper forms. However, the Church’s Business Manager, Margie Roberts, has suggested to Reverend Becker that a computerized system might help the Church better meet its information needs and manage its activities. In addition to Ms. Roberts, the Church employs a part-time administrative assistant, Mabel McGregory. Mabel performs clerical duties such as filing, record keeping, answering phone calls, and typing the weekly church bulletin using WordPerfect for Windows on the Church’s only personal computer. A retiree, Leroy Stricty, is…
Case Study – A Construction Company in Sweden The empirical study is conducted at one of the leading construction companies in the Nordic region that is divided into seven different business areas of which one is Construction Sweden. The company's construction projects have been previously managed in a traditional way with a strong site manager, where the contractor has made up timetables for the project and their subcontractors have consequently been contracted to accept the time slot granted. This enables subcontractors to be less committed to their timeframe and that the site manager has to have a huge workload since he or she has to maintain the focus on all of the activities in the project. After a change in the management team in the construction company's southern region, an initiative to try out a new project management tool called Visual Planning (VP) was started. VP is originally derived from Toyota, and furthermore, adjusted to fit the construction sector. The physical…

Case Study: Montana Mountain Biking Jerry Singleton founded Montana Mountain Biking (MMB) 18 years ago. MMB offers one-week guided mountain biking expeditions based in four Montana locations. Most of MMB’s new customers hear about the company and its tours from existing customers. Many of MMB’s customers come back every year for a mountain biking expedition; about 80 percent of the riders on any given expedition are repeat customers.Jerry is happy with this high repeat percentage, but he is worried that MMB is missing a large potential market. He has been reluctant to spend a lot of money on advertising. About 10 yearsago, he spent $80,000 on a print advertising campaign that included ads in several outdoor interest and sports magazines, but the ads did not generate enough additional customers to cover the cost of the advertising. Five years ago, a marketing consultant advised Jerry that the ads had not been placed well. The magazines did not reach the serious mountain bike enthusiast,…
