Right Answer:
Push notifications are messages sent from a server to a user's device to provide updates or alerts, even when the app is not actively in use. They are implemented using services like Firebase Cloud Messaging (FCM) for Android or Apple Push Notification Service (APNs) for iOS. Developers register the app with these services, obtain a device token, and then send notifications through the server to the specified device tokens.

Right Answer:
Lifecycle methods in mobile app development are functions that manage the states of an application as it runs. They include methods for when the app is created, started, resumed, paused, stopped, and destroyed. These methods help developers control the app's behavior during transitions between these states, ensuring proper resource management and user experience.

Right Answer:
Mobile app development is the process of creating software applications specifically designed to run on mobile devices like smartphones and tablets. It is important because it allows businesses to reach customers directly, enhances user engagement, provides convenience, and enables access to services and information on-the-go.

Right Answer:
To test mobile applications on different devices, you can use the following methods:

1. **Real Device Testing**: Use physical devices to test the app on various screen sizes, operating systems, and hardware configurations.
2. **Emulators and Simulators**: Utilize emulators (for Android) and simulators (for iOS) to mimic different devices and test the app's functionality.
3. **Cloud Testing Services**: Leverage cloud-based testing platforms like BrowserStack or Sauce Labs that provide access to a wide range of devices and configurations.
4. **Automated Testing Tools**: Implement automated testing frameworks like Appium or Espresso to run tests across multiple devices efficiently.
5. **Manual Testing**: Conduct manual testing on key devices to ensure user experience and functionality are consistent.

By combining these methods, you can effectively test mobile applications across different devices.

Right Answer:
The advantages of using a cross-platform framework include:

1. **Code Reusability**: Write once, run on multiple platforms, reducing development time and effort.
2. **Cost Efficiency**: Lower development and maintenance costs since a single codebase serves multiple platforms.
3. **Faster Development**: Accelerated development process due to shared code and resources.
4. **Consistent User Experience**: Uniform look and feel across different devices and platforms.
5. **Access to a Wider Audience**: Reach users on various platforms (iOS, Android, etc.) without separate apps.
6. **Easier Updates**: Simplified updates and bug fixes since changes are made in one codebase.

Right Answer:
* **Epic:** A large, high-level user story that is too big to complete in a single iteration. It's usually broken down into smaller user stories.
* **User Story:** A small, self-contained requirement that represents a valuable piece of functionality for the end-user. It follows the format: "As a [user type], I want [goal] so that [benefit]".
* **Task:** A small, actionable item that needs to be done to complete a user story. It's a technical breakdown of the work required by the development team.

Right Answer:
* **Clear Sprint Goals:** Define specific, measurable, achievable, relevant, and time-bound (SMART) goals for each iteration.
* **Daily Stand-ups:** Facilitate short, focused daily meetings to identify roadblocks and coordinate efforts.
* **Sprint Backlog Management:** Keep the sprint backlog refined, prioritized, and realistic based on team capacity.
* **Timeboxing:** Adhere to time limits for meetings and tasks to prevent scope creep and maintain momentum.
* **Focus on Value:** Prioritize tasks that deliver the most business value within the iteration.
* **Remove Impediments:** Proactively identify and resolve obstacles that hinder the team's progress.
* **Limit Work in Progress (WIP):** Encourage the team to focus on completing tasks before starting new ones.
* **Continuous Feedback:** Regularly review progress, gather feedback, and adapt plans as needed.
* **Defined "Definition of Done":** Ensure a clear understanding of what it means for a task to be considered complete.
* **Team Collaboration & Communication:** Foster open and effective communication and collaboration within the team.

Right Answer:
Kanban focuses on visualizing workflow, limiting work in progress (WIP), and continuous flow. Scrum uses time-boxed iterations (sprints) with specific roles (Scrum Master, Product Owner, Development Team) and events (sprint planning, daily scrum, sprint review, sprint retrospective).

Use Kanban when you need continuous delivery, have evolving priorities, and want to improve workflow incrementally. Use Scrum when you need structured development with fixed-length iterations, have clear goals for each iteration, and benefit from team collaboration with defined roles.

Right Answer:
The Scrum Master is a servant-leader who helps the Scrum Team follow the Scrum framework. They facilitate Scrum events (Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective), remove impediments, protect the team from distractions, and coach the team on Agile principles and practices.

Right Answer:
We ensure consistent Agile processes through:

* **Training and coaching:** Ensuring the team understands Agile principles and practices.
* **Regular audits and retrospectives:** Identifying deviations and areas for improvement.
* **Using tools and templates:** Standardizing processes and providing guidelines.
* **Defining clear roles and responsibilities:** Ensuring everyone knows their part in the process.
* **Promoting open communication and feedback:** Encouraging early detection of issues.

Right Answer:
A procurement administrator is responsible for managing the purchasing process, which includes sourcing suppliers, negotiating contracts, processing purchase orders, maintaining inventory levels, and ensuring compliance with procurement policies.

Right Answer:
The important processes for project integration management are:

1. Develop Project Charter
2. Develop Project Management Plan
3. Direct and Manage Project Work
4. Monitor and Control Project Work
5. Perform Integrated Change Control
6. Close Project or Phase

Right Answer:
Project selection methods are techniques used to evaluate and choose projects based on their potential value and alignment with organizational goals. Common methods include:

1. **Cost-Benefit Analysis**: Comparing the expected costs and benefits of a project to determine its feasibility.
2. **Scoring Models**: Assigning scores to projects based on predefined criteria to rank them.
3. **Payback Period**: Calculating the time it takes to recover the initial investment from the project's cash flows.
4. **Net Present Value (NPV)**: Assessing the profitability of a project by calculating the difference between the present value of cash inflows and outflows.
5. **Internal Rate of Return (IRR)**: Determining the discount rate that makes the NPV of a project zero, indicating its potential return.
6. **Portfolio Analysis**: Evaluating projects as part of a larger portfolio to balance risk and return.
7. **Expert Judgment**: Relying on the insights of experienced stakeholders

Right Answer:
1. **Technical Risks** - Issues related to technology and technical feasibility.
2. **Financial Risks** - Budget overruns or funding shortages.
3. **Schedule Risks** - Delays in project timelines.
4. **Scope Risks** - Changes in project scope or requirements.
5. **Resource Risks** - Availability and allocation of resources.
6. **Quality Risks** - Failure to meet quality standards.
7. **Stakeholder Risks** - Conflicts or changes in stakeholder expectations.
8. **External Risks** - Factors outside the project’s control, like regulatory changes or market conditions.

Right Answer:
The primary purpose of a procurement management plan is to outline how project procurement will be managed, including the processes for acquiring goods and services, defining roles and responsibilities, and establishing timelines and budgets for procurement activities.

Right Answer:
