Ref your assignment
Read carefully the assignment requirement. I'm a bit confused. They asked for at least 3 articles. They asked to describe 3 roles. BUT in the matrix; in order to get excellent marks, you must explain 6 roles.
Therefore, you better stick to 6 roles.
if you only explain 3 roles, you will get less marks.
If I were to do this assignment, I will explain 9 roles. Why? Because I have to get 3 articles, and if each articles outlines 3 roles, the total would be 9.
Another thing is; in our text book, there are only 6 roles. But if you care to search in our e library, google and other sources, you will see more. PLEASE make reference accordingly because otherwise it will look like a cut and paste technique.
You see, in the academic world you cant say that it is your own idea, unless in the special event and situation. When writing assignment you cant do that. At least you can say according to Dr Mahathir during his speech .......
