It is not a zero sum game and the two are not mutually exclusive.
You run two firms. One is a mold-making firm. One is a consulting firm. For the purposes of this discussion, I apply for a job. One of two ways:
1. I submit a resume, cover letter, etc. I seem to have the qualification for the job. Experience in running machines and for the most part keeping them running. If this is an analogue operation, I need years of experience to develop the skill. If this is a digital operation, I need sufficient knowledge to programme the computer for the machine to produce products to spec. Assume I am qualified for the latter. The HR process "processes me." Evaluates my credential, checks my references, sets up an interview or two (the foreman, the maintenance supervisor) discusses my application, sends me a letter of acceptance, and invites me in for orientation and explains the benefits package to me. Fine. HR did it's job. You have a safe hire.
You and I meet here on Linkedin. (We will assume I live nearby.) I tell you I did this work. (We will assume I did) You invite me in, we chat. You have a problem similar to a problem that had to be solved at a company I worked for. They were bidding a job to manufacture a part that didn't work properly for the customer. Think of a long, triangular tube. Into it, another triangular tube had to slide easily in and out. It didn't. The engineer could not solve the problem. The man with many years of experience showed me the blueprints, the spec sheet, and the proto-type. There was a + or -- .50 degree tolerance. 60 degrees + 60 degrees = 120 degrees. However, 60.50 degrees and 59.50 degrees also = 120 degrees. 60 + 60 produces a part that does not function. 60.50 + 59.50 produces a part that does work. Why? I don't know. I am not an engineer. (I do come from a generation that taught us to say, "I don't know," when we don't know, but that is a social issue.)
Now, why bring this up? I might get a job working as a mold maker in your mold company (If I have some credentials.) if I go through the HR process. I am a safe hire. However, if you and I chat (assuming I am the "other guy") you will hire the better
candidate for the job. HR hires me. You hire the other guy.
HR give you the safe hire. You, management, end up hiring the best employee. Does your HR. person have engineering qualifications? (I am not saying this to disparage your or anyone else's HR dept.) Let HR do the benefits thing, and so on. Hiring, in your profession, requires that you, the foreman, the engineer, the maintenance supervisor (keeping the fancy machines functioning because the safe hires can't and it would definitely be cost prohibitive for you to duplicate skills) interview and decide on the applicants.
