This technique can be ok only for beginners. I am not sure the result of the translation can be of use. As you know a single word has many and sometimes very different meanings. To select a proper and the closest meaning to a word it has to be considered with the whole structure of the sentence and text. A rich general knowledge, high source and target language skills, experience and practice + good use of technology and techniques are necessary for a quality translation.   

Why do you waste your time doing this? There are online free translation doing just the same. The "translation" is useless - in almost all cases, it doesn't make any sense at all.

I certainly disagree with this technique, because its result is poor translation. First of all, the translated text shouldn't follow the English pattern, like word for word, and I foresee that danger in using this technique. The translation should flow and be natural. It should speak the language of the intended readers. The target audience should not even be able to back-translate, of which I think it will be the case if one is to follow this technique.

On top of that, a good translator don't just rush into his source text and start translating, rather he should have an overview of the source text, that is to mean browsing over the text (look at the main title, subtitles, captions, pictures etc). This gives him an idea of what the source text is all about. Then he can do the inside-view, and that's when he goes through the whole material, reading it thoroughly and marking the difficult areas that will need more research. After research then he crystalize the information into his mind. Asks himself questions like.....How will I put this expression in a more simple, natural and clear language that my audience would understand? etc. That's when now you can start translating after having a full understanding of the source text, always keeping your audience in mind.

I totally agree with Max. I think that is the best way to translate any document.
