U do not need scrum

Well, I tried scrum. Honestly. It's a pretty good development method and very effective. If everything goes right, it may rapidly increase yr and teammates development speed. Everyone knows his tasks and may predict time to complete them. If something changes, there will be time to easily change direction of development and fix everything up.
Unfortunately, scrum has its own boundary of applications. In imaginary ideal world, where everything is predicted and anything u want to do u do from first attempt it is an ideal solution. But we live in other reality where above mean sea level may be positive and negative values, where sin or cosine values can be any value and there's no prohibition of taking square roots from negative numbers. And there's no place for creativity.

So, it's just words. Why do u need scrum? U need scrum:

• when u have detailed, self-explanatory concept document
• when u know exactly yr tasks
• when u can estimate yr tasks
• when u have an image of app in yr head  and may guess how it would work
• when u need to quickly get results
• when u need to see changelog of the app

But u do not scrum:

• if there's no agreement with teammates about design and functionality
• if u can not estimate yr tasks, because it's a creativity process depending on inspiration
• and u can make over one task again and again
• if u need to create something new, conceptional

Now I have six tasks on my board and can estimate three of them. Others are connected with design and may be overdone many times. So, if u ask me when I'm gonna finish my work and release next version, I won't give u any estimates or predictions. Even if I do, that will be not truth.
