1. How does the Agile model compare to the Waterfall model?
  - Waterfall is rigid and resistant to change, whereas Agile is designed at its core to deal with and embrace changing circumstances.
  - Agile produces smaller bits more quickly, with the aim of a better product by the end of development.
  
2.  Why do you think Agile is so popular in software development?
  - Software is incredibly maleable and will inevitably change, so a process of design that keeps these facts in mind will result in a better product.
  
3.  Do you think Agile is applicable in all industries?
  - Most likely yes, it's applicable in all. Whether or not it is the best fit for all industries is another question. I would imagine that with increasing simplicity of the project, the more waterfall would fit the process. As complexity increases, I would imagine Agile to become increasingly useful.
