Unconventional capitalisation becoming the norm

Having now been involved in the writing of quite a few proposals as part of my job, I've noticed what seems to be a de facto convention: what I would consider common nouns or common noun expressions are capitalised. My inference is that this is for emphasis, or to assign significance to the thing being referred to.

For example:

... any variation impacting cost will be raised with the Client via a Project Change Request.

Has this now become accepted practice (in a de-facto sense, I presume)? Is it "correct" English?

Solution 1:

In the specific example you gave, I find the capitalization of Process Change Request to be quite standard, because that is likely a specific, titled form/action used by the business in question. I think every job I've worked at in the US had between a couple and dozens of items like this--things like Team Performance Report. I personally find capitalizing "Client" to be unusual, but, like others have said, if that's standard in a particular field or a single company, then it is "correct" within that space.
