ISA 235 Chapter 9 questions with verified
answers
advantages of prototyping Ans✓✓✓ 1. Encourages active user
participation
2. evolve through iteration, which better supports change
3. have a physical quality allowing users to see, touch, and experience
the system as it is developed
4. prototypes tend to detect errors earlier
5. accelerates the phase of the SDLC, helping to ensure success
agile methodology Ans✓✓✓ aims for customer satisfaction through
early and continuous delviery of useful software components developed
by an iterative process using the bare minimum requirements
analysis phase Ans✓✓✓ the firm analyes its end-user business
requirements and refines project goals into defined functions and
operations of the intended system
brainstorming Ans✓✓✓ a technique for generating ideas by
encouraging participants to offer as many ideas as possible in a short
period of time without any analysis until all the ideas have been
exhausted
bugs Ans✓✓✓ defects in the code of an information system
, business requirements Ans✓✓✓ the specific business requests the
system must meet to be successful, so the analysis phase is critical
because business requirements drive the systems development effort
change agent Ans✓✓✓ person or event that is the catalyst for
implementing major changes for a system to meet business changes
computer-aided software engineering (CASE) Ans✓✓✓ software suites
that automate systems analysis, design, and development
computer-aided software engineering (CASE) Ans✓✓✓ tools which
provide automated support for the development of the system
Control Objects for Information and Related Technology (COBIT)
Ans✓✓✓ a set of best practices that helps an organization to maximize
the benefits of an information system, while at the same time
establishing appropriate controls to ensure minimum errors
conversion Ans✓✓✓ the process of transferring info from a legacy
system to a new system
corrective maintenance Ans✓✓✓ makes system changes to repair
design flaws, coding errors, or implementation issues
critical path Ans✓✓✓ estimates the shortest path to complete the
project
