One of the most common deceptive issues companies face is where the programmer or web developer they work with is not qualified and they do not know it. In these cases the programmer will often blame their inability to complete jobs or resolve issues on "documentation" or third party systems that they are attempting to work with. They do this rather than admitting that they are not qualified to complete the job they were hired to do.
Sadly this then leads to the business owner blaming the third party services or scripts they are attempting to integrate with. Often the issue is so simple and so easy to resolve but costs them dearly in wasted money and time and often is aggravated by the business owner seeking assistance only to find themselves in the same situation as before because they hire yet another unqualified pretend "web developer" to assist them.
If you are outsourcing or working in an environment where you do not have a true "developer" overseeing your programmers I highly encourage you to pay a true developer to consult you in hiring qualified "programmers" and "web developers" and to help you identify the real issues when they arise.
Do not allow your self to be deceived by unqualified "programmers" and fake "web developers" who do not have the qualifications required for the title "developer."
