We are writing an article "marketers vs. developers" and need developers to answer a couple of questions:

1. What are the main and the most important things in the brief for the developer?

2. What is often forgotten to be included in the brief (something needed for further work)?

3. What is not as important but appears in brief?

4. How can marketers help developers with his/her work? What information to provide, how to set a task?

5. How do marketers interfere developers while thinking that they are being useful?

The main point of the article is to explain to marketers how to create an ideal brief. I would say a big-big Thank you for those who decide to help us :)
