ANSWERS TO CASE-SIM: SCR ASSOCIATES
Introductory note: The SCR case study provides a valuable real-world experience for students. The case involves an imaginary IT consulting firm that maintains a realistic Web site, complete with a company intranet that students can access. The student becomes an entry-level systems analyst reporting to a supervisor named Jesse Baker. In each session, the student receives e-mail messages, voice mail messages, and a list of tasks to perform. The voice mail all comes from Jesse Baker, and the e-mail messages come from Jesse Baker and other members of the firm. Each message contains guidance and direction that would be typical of a real-life situation. After reading the e-mail, listening to the voice messages, and consulting the task list, the rest is up to the student. He or she must go back to the chapter, review the terms, concepts, and skills, and then apply them in the context of the case study. Four main tasks occur in each session. A typical task might require the student to prepare an e-mail message, a memo, Internet research, or a graphic element such as a chart or diagram. The task list for Session 1 follows. 1. Investigate SCR’s Internet site and learn about the company’s history, purpose, and values. Send Jesse a brief memo with suggestions to expand or improve these sections. The SCR Web site includes realistic features, content, and links that allow students to learn about the company and its background. Encourage students to find examples of other IT consulting firms and compare them to the SCR site. This task could tie into assignment 4, which requires Web research to find other firms. It would be helpful to get students interested in the SCR site’s design and navigation features before they start working on the case itself. Students with a background in Web design probably will have suggestions and comments to share with the class. 2. On the SCR intranet, visit the data, forms, and resource libraries and review a sample of the information in each library. This task provides an overview of the site and will give students a valuable introduction to the case study. If you have not done so already, this would be a good time to explain the main features of the case study, which include the SCR intranet, personalized e-mail messages, the reference libraries, and the task list for each session.

Using the SCR functions and organization listed in the data library, create an organization chart using Microsoft Word, Visio, or a drawing program. Students can use the list of SCR functions and organization (Document 1-2 from the data library) to create an organization chart. A sample chart follows: Executive Committee Gary Smith Thomas Campbell Harry Richards Systems Group
Network/Web Support Group Manager
Manager Jesse Baker
Programmers Robert Newman Marge Clark Dave Spencer
Business Solutions Group Manager Lynn Chou
4. Jesse says that SCR has plenty of competition in the IT consulting field. Get on the Internet and find three other IT consulting firms. She wants a brief description of each firm and the services it offers. Students should have little difficulty locating IT consulting firms. This would be a good topic for student reports, and for actual visits to the online sites if computer resources are Web Designers Mark Martin Ho Lee Bill Loos

Changes should be a result not an intent
done through a process of evaluation.
In SystemDesign (SYSDES):
Analysis is very important because it is used to gain an understanding of an existing system, and it defines only the requirement of a new system. After you analyze, you design a system.
Design is used to build a fresh or changing the existing system. In designing you propose a new system that makes the requirement of the said institution. After designing the system will build.
Build used if the designsystem was approved.

At present, people experience and do a lot of work to accomplish certain tasks with less time. Computerized systems have made manual labor easier and more efficient. These computer software applications are developed to provide excellent results. Through the use of computers, the business becomes more competitive and software systems are developed to enhance its potential.
Information system is classified into two: manually or non-computerized system, where all the information is written and stored in different files; automatically or also known as computer based information system (CBIS). Non-computerized system is ineffective due to the fact that it consumes a lot of time to find and revise information. To solve this problem, a new system is formed which is known as the computerized system or CBIS.
System development life cycle (SDLC) is a set of independent items that work together to perform a task. The system analyst is responsible for the design of the new system and application. SDLC consists of steps which are, Analysis (problems), Design (how the system flows), Coding (programming language to be used), Testing (performance of the system), Implementation (delivery), Maintenance...
Case Problem 2: Forecasting Lost Sales
1. The data used for the forecast is the Carlson sales data for the 48 months preceding the storm. Using the trend and seasonal method, the seasonal indexes and forecasts of sales assuming the hurricane had not occurred are as follows:
Forecast ($ million)
2. The data used for this forecast is the total sales for the 48 months preceding the storm for all department sores in the county. Using the trend and seasonal method, the seasonal indexes and forecasts of county-wide department store sales assuming the hurricane had not occurred are as follows:
Forecast ($ million)
3. By comparing the forecast of county-wide department store sales with actual sales, one can determine whether or not there are excess storm-related sales. We have computed a "lift factor" as the ratio of actual sales to forecast sales as a measure of the magnitude of excess sales....
Background of the study
An automated system nowadays is becoming prominent for a business that needs accurate, efficient and reliable results.
Today, many businesses are engaging to automated systems, its manual setup can be applied automatically through computer. By using a computer, a business can perform its transaction in a less amount of time. Having a way to organize transactions by the use of automated system is an asset. Especially when you apply the automation to the most commonly used transaction, Sales and Inventory System.
Inventory is a list of goods and raw materials that is needed for the everyday production of a business which is held available in stock. Updating the records of the stocks in a business plays an important part for the organization of business functions. Manual application of transaction can bring interruption, thus, the Automated Sales and Inventory System is considered as the best solution to this problem.

ASSIGNMENT: CHAPTER 15
PRELIMINARIES TO EROSION: WEATHERING AND MASS WASTING
KEY TERMS AND CONCEPTS:
1. What is meant by denudation?
The total effect of all actions (weathering, mass wasting, and erosion) that lower the surface of the continents.
2. Distinguish among weathering, mass wasting, and erosion.
Weathering- The physical and chemical disintegration of rock that is exposed to the atmosphere.
Mass Wasting- The short-distance down slope movement of weathered rock under the influence of gravity; also called mass movement.
Erosion- is the detachment, removal and transportation of fragmented rock material.
3. What roles do rock openings play in weathering processes?
Whenever bedrock is exposed, it weathers. Weathered rock often has a different color or texture from neighboring unexposed bedrock. Most significant from a topographic standpoint, exposed bedrock is likely to be looser than the underlying rock. Blocks or chips maybe so loose that they can be detached with little effort. Sometimes pieces are so “rotten” that they can be crumbled by finger pressure. Slightly deeper in the bedrock, there is firmer, more solid rock, although along cracks or crevices weathering may extend to considerable depths. In some cases, the weathering may reach as much as several hundred meters beneath the surface. This penetration is made possible by open spaces in the...
