Answer 2

Development, maintenance and management

Question 3

What is Software?

Answer 3

• Requirements Specification Document
• Design Specification Document
• Programs
• Test Cases
• User and Technical Documentation

Question 4

What are Large Software Systems?

Answer 4

• large number of functions, classes, and lines of code
• team of developers
• high cost
• lifetime measure in years
• software costs dominate hardware costs

Question 5

What is the Science of Building Large Software Systems

Answer 5

On time/within budget, correct operations, acceptable performance

Question 6

What was the Software Crisis?

Answer 6

Requirements of projects were unclear/unmet, no describing what the software should look like or do, high cost and pressure, and lack of coordination within the team

Question 7

What are the two types of software?

Answer 7

• Generic products: developed for a general market
• Bespoke (customized): developed for a specific organization/company

Question 8

What are the 6 phases of software life cycle?

Answer 8

• Feasibility Study: should we proceed with the proposed project?
• Analysis: describe the problem requirements.
• Design: produce a high quality solution to the problem. (build software architecture and refine to modules)
• Implementation: implement the solution. (produce source code)
• Testing: was the problem solved? (assess each quality)
• Maintenance: fix bugs, enhance features, adapt to new things.

Question 9

Why is Software still Delivered Late?

Answer 9

• Changing requirements not reflected in schedule
• Underestimation of technical difficulties
• Unrealistic deadlines
• Lack of communication among project members
• Fail to see that the project falls behind schedule

Question 10

What are some Production Activities?

Answer 10

• Analyze problem requirements
• Decide on high-level software architecture
• Refine architecture
• Implement and test programs
• Write user documentation
• Release to the customers
• Provide support and maintenance

Question 11

What are some Management Activities?

Answer 11

• Conduct the software feasibility study
• Plan and schedule the development tasks
• Estimate the total cost
• Coordinate among developers
• Manage risks (miscalculation or coworker leaving)
• Track progress of project completion

Question 12

What were some of Technical/Practical disasters with Software Before?

Answer 12

• Improper code reuse
• Inadequate testing
• Over budget
• Logical problems that is rare and unique.
