My problem about writing a technical/research report/paper I have seen several questions on this forum that have similar things and some of them have been quite satisfying for my quest. But I want to mention my specific case and want to have some useful suggestions, so I am writing this, which maybe or may not be a redundant question.

In my work as a research associate, I always have this problem which irritates me a lot.

Every time at the start I have to study something, of course related to my area but a somewhat new for me (painful, but this is what anybody has to take it to get the job done), learn it and apply it (I would say the apply part is the sweet/joyful pain).

Suddenly the next demand comes as "Write down" and it is where the pain concern ends and I start feeling as if my hands are cut and my mind is blank and "ME" can never do it.

Sometimes the demand is "Write down and make it as long as you can and we will make it short later", the torture is, for God sake I do not have even a few words to write!

Problem as I feel it: 

Even after doing everything by myself, I feel that I can not describe it in writing. While if it is about describing it orally I am confident that I am much better than many. 

When it comes to writing, I never know what to include and what not, especially when the demand is about as long as you can. I have had read tens of writings and have had done the things practically by myself but no idea what makes my mind blank about writing technical things.

I feel myself really good at doing technical things and love it.

Finally, I think I am missing some steps involved in that writing and I never miss the steps of doing things practically making me successful in that.

If these are steps, what are these?

If these are not the steps, what else are these?

Many times I have got my office reputation damaged because of going blank even after many days/weeks given to me for writing. I want to get rid-off this problem and want it never happen again. I would love to be the researcher who satisfies the demand of as long as you can?

A foot note: In general I do not feel myself bad at writing, though my answers to most emails and my own emails are mostly brief but satisfy the receivers. One more thing to mention that might be useful to assess/suggest me is that it took me around an hour to complete this question completely.
I suspect you are finding this difficult because you are trying to write in an academic style, and are judging yourself as you are writing. I think the secret to easier writing is to spend as little time as possible "writing". Instead, spend your time jotting quick emails and editing stuff. Let me explain what I mean.


Get together with someone who knows nothing about your research, and explain it to them. Record yourself, or at least take notes on the main points that you address.
Now write your explanation down, but informally, as if you were writing an email to a friend. Better yet, make it a real email -- that will help you keep it informal.
Also gather any other emails you've written to your supervisor, or colleagues and friends. (If you're not already doing so, get into the habit of writing those emails regularly, while ideas are fresh in your mind.)
Take those emails, and paste them into an empty document. This will be the starting point of your paper.
Now rearrange the information as needed, to make it coherent. Everywhere there's a gap, stick in a message like NEED TO EXPLAIN X HERE.
At this point, you're beginning to have an idea of the structure of the paper. This would be a good time to write an outline, to see if you've left anything out. This outline goes into the document along with everything else. (You can delete it before submitting the paper.)
Now fill in the gaps. But write informally, as if you were writing an email to a friend.
Now go through your document, and make the sentences more formal. Don't overdo it, though. You don't want your writing to be stilted; you want it to sound natural.


Congratulations. You have the first draft of your paper, and you barely did any real "writing"; it was mostly just writing emails and editing. 

It's much easier to make informal, but clear, writing more formal, than it is to make formal writing more clear!
