Information-Technology-Management Exam Dumps - WGU Information Technology Management QGC1

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.

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.

Understanding Virtualization:

Virtualization is the process of creating virtual versions of physical resources, such as servers, storage, or networks, to maximize their utilization.

Cost Reduction and Simplified Management:

Virtualization reduces hardware costs by allowing multiple virtual machines to run on a single physical server.

It simplifies IT management by enabling easier resource allocation, scaling, and disaster recovery.

Why Other Options Are Incorrect:

Option A: Virtualization increases resource availability, not restricts it.

Option C: Virtualization enhances workload distribution, reducing stagnation.

Option D: It reduces reliance on manual operations by enabling automation and centralized control.

Prototyping in Software Development:

Prototyping involves creating a working model of the system to validate that it meets user and business requirements.

It is an iterative approach where users interact with the prototype and provide feedback for improvements.

Why Other Options Are Incorrect:

Option A (Waterfall): Follows a linear approach without iterative feedback.

Option B (RUP): A structured iterative approach but not focused solely on prototyping.

Option C (Iterative): While iterative development involves cycles, it does not specifically focus on building prototypes.

Role of Executive Sponsors in a Project:

Executive sponsors are senior stakeholders responsible for providing financial resources and ensuring the project aligns with organizational strategy.

They advocate for the project at the executive level and help remove obstacles that could hinder its success.

Key Responsibilities:

Securing funding and allocating resources.

Ensuring alignment with business goals and priorities.

Supporting the project team by addressing high-level challenges.

Incorrect Options Analysis:

A. Tracking milestones: This is typically the role of the project manager.

B. Developing the project plan: Also the responsibility of the project manager.

D. Representing staff interests: Sponsors focus on organizational priorities, not individual interests.
