Buzzer is used to generate sound, beep or even melody of a song. It can be found in alarm devices, computers, timers and confirmation of user input such as a mouse click or keystroke. A piezo buzzer is not like a regular speaker that you might think of. It uses a material that actually changes shape when you apply electricity to it which in turn creates noise. The faster you bend the material, the higher the pitch of the noise that is produced.

In Agile, measuring success isn't just about counting completed tasks - it's about ensuring teams continuously improve while delivering value. Without metrics, teams might feel like they're making progress, but they wouldn’t have clear evidence of what's working and what isn't. The right metrics give teams visibility into their workflow, highlight areas for improvement, and help them make better decisions. But Agile isn't about chasing numbers - metrics should support improvement, not dictate behavior.

Agile helps teams adapt, deliver value faster, and improve continuously. However, applying Agile in real projects is not always smooth. Teams often run into resistance to change, unclear priorities, inefficient collaboration, and struggles with Agile scaling.
These challenges can slow down progress, frustrate teams, and make Agile feel like more effort than it's worth. But the good news is that Agile itself provides ways to address these problems. Recognizing common obstacles and knowing how to handle them helps teams get the most out of Agile without falling into frustration or inefficiency.
