Dear Sajaduk,
I have accessed your posts and also seen your profile, which does not give much info about you.
As you have raised questions about PEST and SWOT analysis in the past, I wonder what your background is and what you do! Hence, could you kindly provide us details about you and why you have raised this question.
Have you searched the web for this information? If you have not done that, please go to
https://www.google.co.uk/webhp?sourc...on%20structure and then tell us what you understand by those terms and then how relevant it is to your organisation's culture.
