Which statement describes the development phase of the systems development life cycle (SDLC)?
Answer(s): A
Understanding the Development Phase in SDLC:The development phase involves translating system design specifications into actual software.This includes coding the system using programming languages and integrating modules as per the design.Why Other Options Are Incorrect:Option B: Describes the maintenance phase, which focuses on updates and corrections post- deployment.Option C: Relates to the testing phase, where interoperability and functionality are verified.Option D: Refers to the implementation phase, where the system is deployed for user operations.SDLC Phases Explained NIST SP 800-64"Software Development Life Cycle Best Practices" IEEE
Which benefit does a prototype provide to a client?
Answer(s): B
Purpose of a Prototype:A prototype is an interactive model that demonstrates how a system or interface works.It allows clients to experience the functionality and interaction before full-scale development.Why Other Options Are Incorrect:Option A: Prototypes are not detailed development instructions.Option C: Prototypes are not blueprints but are functional models.Option D: Prototypes are dynamic and interactive, unlike static examples."Prototyping in Software Development" GartnerBest Practices in Prototyping Agile Alliance
A team tests a prototype prior to meeting with a company's client and discovers the "My Account" menu is not working. The team revises the code and presents a functioning prototype to the client.Which advantage of prototyping does this describe?
Answer(s): C
Advantage of Prototyping:Prototyping allows teams to identify and resolve issues, such as coding errors, early in the development process.This minimizes the risk of errors propagating into later stages.Scenario Application:The team detected a menu functionality issue in the prototype, revised the code, and presented an updated version.This demonstrates the value of early error detection through prototyping.Why Other Options Are Incorrect:Option A: Prototypes are not static examples.Option B: Prototypes are not project blueprints.Option D: Prototyping is not about creating development instructions."Benefits of Early Prototyping in Development" Agile Manifesto PrinciplesPrototyping Methods and Applications ISO 9241
When should a product management team utilize a prototype?
Purpose of Prototypes in Product Management:Prototypes provide a working model of the product to collect user feedback.This helps the product management team refine the application and address usability issues.Why Other Options Are Incorrect:Option A: Showing feature interaction is a secondary purpose but not the primary reason for using a prototype.Option C: Testing user interfaces may involve prototypes, but the main purpose is feedback collection.Option D: Prototypes are not typically used for creating training materials."Role of Prototyping in Product Development" Product Management InstituteAgile Prototyping Guidelines Scrum Alliance
A finance company wants to analyze subjective financial values of intangibles such as goodwill.Which type of artificial intelligence should it use to meet this goal?
Answer(s): D
Fuzzy logic is an artificial intelligence approach used to handle uncertainty and imprecise data. It is particularly useful for analyzing subjective financial values such as goodwill, brand value, and customer perception, which do not have precise numerical definitions. Unlike traditional Boolean logic, fuzzy logic allows partial truth values between 0 and 1, making it ideal for financial analysis where subjective judgments play a role.Zadeh, L. A. (1965). "Fuzzy Sets". Information and Control, 8(3), 338353.Ross, T. J. (2004). Fuzzy Logic with Engineering Applications. John Wiley & Sons.
