Do you think CV is a good criteria to determine ability to perform a job duty and responsibility?

I think the CV is not enough ,just to give an idea about the person.
You can decide better on the practical levet if the candidate suite the position or not.

A curriculum vitae is just an abstract of the whole book of a persons Knowledge, skills, abilities and work background, but what lies inside is yet to be explored.
The Curriculum Vitae is just intended to be give a first impression of the person and his fitness against the pre-set criteria.
On the basis of curriculum Vitae one cannot determine whether a person fit to perform a job duty and/or responsibilities as you said.
There is a complete set of tools for this purpose which include:1) Receiving of Curriculum Vitae2) Short-listing3) Interviewing and screening4) Job Sample5) Evaluation and selection.

CV is a simple summary of the definition of the person and his achievements during the previous currency

A CV does not necessarily determine if a candidate can perform a certain role.
However, since a CV is the first interaction a candidate has with an employer it is the initial step of landing a job.
A good CV reflects on the candidate and will get them to next stage which is interviewing.
This is when a candidate can further explain how and why they will be able to perform.

CV cant determine one's ability for performing a duty.
it could just give you a brief detail about the knowledge and experience you have got!

Hi - A CV generally gives an idea about cadidates domain and expertise, but it is the interview and joining of the candidate in an organisation where he has to prove that what was written in the CV is more than200% satisfactory...

No deep360 degree probe is required

A CV potrays important information about a candidate and can partly influence the employer to hire or not hire the candidate.
  However Ability to Perform can only be assessed only during an Interview with reference to the CV.

It give a general Idea about the person you need that fit the criteria or not.

Dear Bukayo, Definitely.
A clean, simple, neat and well-presented cv would make a really good impression to the person who doesn't even know you. 
CV is the first thing the interviewer uses to decide if he/ she would like to meet you up or not.
And the impression is basically founded by reading your profile.
If it is clear, well-presented and well-formatted, you should score a higher chance to be granted an interview. 
If you want your CV reflect your responsibilites & how you are a good Employee you have10 things you should have in your CV:     Contact details    It’s important to provide a range of contact options including your home address, your main phone number and your email address to make it easy for employers to get in touch with you  Employment history    Make sure to include the jobs that are relevant to the position you are applying for.
If you haven't had much relevant experience, however, you may want to include your whole work history. 
   Education and qualifications    Your education and qualifications may not be directly related to the job you are applying for, but they’re still important achievements that any employer will want to see. 
   Skills and strengths    Emphasising your skills and strengths is vital when building a CV.
A strength is something you’re naturally good at.
A skill is something you acquire with education and experience.
Make sure to demonstrate how your skills and strengths will help you to do well in the job. 
   Your personality    Your CV should follow a fairly standard format and the interview is where your personality is really important, but you can still stand out from the crowd with the language you use.

   A prioritised layout    The way you layout your CV will depend on your age and work experience level.
My CV allows you to choose between a work-focused or education-focused template.
If you have don’t have much work experience or you’re looking for a career change, you should place your skills and strengths section before employment and education. 
   A good simple format    Unless you’re going for a highly creative job, getting too fancy with fonts and borders will only take the focus from the important information in your CV. 
   Good spelling and punctuation    There’s no room for poor spelling and punctuation in either your cover letter or your CV.
Keep sentences short to avoid confused punctuation and, if you can, give it to a friend to check it over.
Spell check should be the very last thing you do before sending it off. 
   References available on request    You don’t have to include references in your CV and leaving them out will save you space, but make sure to state at the end of your CV that they are available on request. 
  A cover letter    Most employers will expect a cover letter with your CV.
It gives you a chance to get across your personality, ambition and to explain any gaps in your CV.
