Business Systems Design
Pre-Test Questions
Course Introduction
Business Systems Design explores the principles, methodologies, and tools essential for analyzing, modeling, and constructing effective information systems that support organizational objectives. The course covers the entire systems development lifecycle, including requirements gathering, process modeling, and systems architecture. Students will learn to translate business needs into technical specifications, design user interfaces, and consider system integration and security concerns. Emphasis is placed on practical application through case studies and project work, preparing students to bridge the gap between business processes and information technology solutions.

Q1) Extreme programming is ideal for developing large mission-critical applications.
A)True
B)False
Answer: False
Q2) Describes the roles of and activities performed by the business analyst and system analyst.
Answer: A BUSINESS ANALYST identifies the business value that a system will create, develops ideas and suggestions that improve the business process, and designs new processes and policies. Work experience of a business analyst is probably in the functional field or application, such as accounting, marketing or production management.
A SYSTEMS ANALYST develops ideas and suggests technology innovation to business processes, designs new business process and information systems, and ensures that IS standards are maintained. Work experience of a systems analyst is probably in analysis and design, programming, or some business area.
Q3) Parallel development relies on only one iteration of the analysis phase.
A)True
B)False

Q1) The unadjusted total function points of a system are frequently adjusted to reflect the complexity of the system. Describe two ways to determine the appropriate complexity adjustment factor.
Answer: One method requires the project manager to rate the complexity of fourteen project factors on a scale of 0-5. These ratings are added together, and then adjusted to obtain a complexity factor that either inflates or deflates the function points of the project. The second method provides a shortcut to this rather lengthy process:the project manager simply chooses a complexity factor from a standard range (0.65 for simple projects to 1.35 for very complex projects)and applies that factor to adjust the project function points.
Q2) Integrated CASE, or I-CASE, contains functionality found in both upper CASE and lower CASE tools in that it supports tasks that happen in the software design, the implementation and the software testing.
A)True
B)False
Answer: False
Q3) Give the formula for the schedule time in months, given the effort in person-months. Answer: Schedule time (in months)= 3.0 X (person-months)¹ / ³
