Research:

1. Regarding the optimization of resources and increase of profitability through project management tools, research has indicated that these tools dramatically improve communication, increase efficiency by automating routine operations, allow for better planning and forecasting, reduce project costs and ultimately increase profitability (Spalek, 2014).
2. Scrum teams and development teams differ mainly in their scope and roles. a Scrum team includes a product owner, scrum master, and the development team. Each role in this framework is limited in its responsibilites. A development team, on the other hand, may refer to any team working on a software product, not necessarily within the Scrum framework (Schwaber & Sutherland, 2017).
3. Efficiency in software development teams can be ensured by reinforcing clear communication among team members, defining roles and responsibilities, prioritizing tasks, using suitable project management tools, and promoting a culture of continuous learning (Sutherland & Schwaber, 2016).
4. A high-performing software development team typically include: the product owner, the Scrum Master, and the developers who are composed of frontend and backend developers, QA experts, UX/UI designers, and sometimes a system architect (Sutherland & Schwaber, 2016).
5. The best approach to team building depends heavily on the specific requirements of the project. However, common strategies include defining clear roles and responsibilities, assembling a team with diverse skills and expertise, and fostering open communication (Seliger, 2016).
6. In Agile development with Scrum, the role of the project manager is often filled by the Product owner or Scrum master. The product owner is responsible for defining the product's features while the Scrum Master ensures that the development team can focus on delivering high-value increments (Sutherland & Schwaber, 2016).
7. High-performing teams often demonstrate characteristics such as clear communication, mutual trust, conflict resolution skills, adaptability and a strong work ethic (Katzenbach & Smith, 1993).
8. An Agile development team is a cross-functional group of professionals who self-organize and autonomously manage their own work. They possess a dynamic set of skills which allows them to respond swiftly and iteratively to changing project requirements (Hoda, Noble, & Marshall, 2011).
9. Development teams face numerous challenges like managing changing requirements, ensuring high-quality deliverables, coping with technical debt, maintaining effective communication, and retaining skilled staff (Bass, 2016).
10. Team performance can be measured through various metrics including, the volume of work completed in a given time (velocity), the quality of work (defect density), team satisfaction, and customer satisfaction (Pankratz, & Hall, 2017).
11. Development teams can work efficiently using different frameworks depending on the project, as long as they have undergone appropriate training and have sufficient experience with the framework in question. However, an abrupt switch between different frameworks could pose adaptability challenges (Pernstål, Feldt, & Gorschek, 2019).
