Apparently PMP doesn't include reading comprehension, because you're attacking straw-men. Go back and read what I wrote, and see if you can come up with a more coherent response.
I will try to reword my response so that you are capable of understanding my straight-forward point.
Most of your post is trying to explain why PMP is important. You do it by saying, "the person will have to learn X, the person will have to learn Y, the person will have to know Z." In other words, to show that the certification has value, you also show that a person can learn something by getting the cert.
A certification does not teach, it certifies.
CERTIFY (transitive verb)
- attest or confirm in a formal statement.
"the profits for the year had been certified by the auditors"
synonyms: verify, guarantee, attest, validate, confirm, substantiate, endorse, vouch for, testify to;
- officially recognize (someone or something) as possessing certain qualifications or meeting certain standards.
The irony is thick here. You accuse me of a lack of reading comprehension skills, while you do not understand the meaning of the word, "certification".
You're trying to come up with some roundabout logic that a certification implies learning, or forces you to learn, but that is incorrect. It is subjective and may hold true for some. But I will repeat, a certification is not meant to teach. Technical certification or otherwise.
Of course there are people who already have the skill.....should they get the certification? Usually those people already know if the cert is worth getting or not. They don't ask that question. Furthermore, for those people, a certification is not hard to get, spend a few hours taking the test, a few hundred dollars, no big deal, if they have to.
In some cases, certifications are mandatory. Civil aviation for example. In most countries, an aircraft engineer (the guy who inspects your aircraft before it takes off) needs to be certified by a central civil aviation governance body. They get certified and licensed for a specific model of aircraft and have to periodically renew their license to continue to do their job. Regardless of what skills they possess or how many years they have been doing it.
If a certification is not hard to get, and if it adds value to your resume (or so you think), then I am not sure why someone would not get it. It sounds like a no-brainer. And in some ways, it the same argument that someone would make to get a college degree. And many would advice you to get it, even though the cost and time commitment are non-trivial.
The entire argument in this thread hinges around a "bottom of the barrel" argument. If you are being interviewed for a job by incompetents, or work in an oganization that values certification over skill, that is a different matter. However, these two aspects (organizations valuing certifications, and organizations valuing skills) are not mutually exclusive. There are many organizations that value both, and people who do not hold this easy to get certification, are at a disadvantage. Just as someone from a good school does enjoy some advantages even in good engineering oriented or dynamic organizations.
And by your logic, no-one should be required to get a driver's license, especially for those people who feel really confident of their driving skills.
And jeez man, you don't have to get antagonistic. You triggered me off, and I realize it in hindsight. So I guess I am too.
