@nirmal1982,
Hi,
Here are a few suggestions and comments for you:
1) You need a comma after "Contributing to difficulties in maintaining such positions[INSERT COMMA]"
2) Remove the comma splice from "This is because they create a significant necessity for manufacturers to not only more precisely monitor markets [NO COMMA] but also generate and adapt their products in-line with them."
3) Remove the comma splice from "Failure to implement such practices can result in overlooked market opportunities [NO COMMA] and hence an inability to capitalize upon them."
4) Your last sentence is rather awkward. I would recommend using '-' to make it easier to read like this: "However, whilst this appears to be a prerequisite--to be truly competitive--manufacturers must not only generate products, processes[COMMA -but personal style] and services that are in-line with the market[NO COMMA - this is a comma splice] but also innovative, and therefore [add word? 'stay'] ahead of it.
I would give your writing a 7. You have good use of phrases such as infinitive phrases, and your cohesion is good. However, you need to brush up on the basics, especially comma splice rules. Only independent clauses joined by a conjuction can have commas (

Good luck though!
