In an article, titled "Why PHP sucks", on bitstorm.org, Edwin Martin complained about not having a standardized framework for PHP. He cited Struts for JSP developers and .Net for ASP developers as models for a standardized framework for PHP. As opposed to a standardized framework, PHP has a multitude of open source frameworks including Midgard, Horde, Blueshoes, Cake, Seagull, Sourdough, binarycloud, SMART, and many others. Compare and contrast having a standardized framework verses multiple privately developed frameworks. Use your analysis to build an argument defending or refuting Martin's complaint.

I'm not familiar with showing validity and reliability on interviews, but I am with getting Cronbach alphas on questionnaires. I use SPSS's reliability analysis tool in the Analyze menu under the Scale option. Eliminate questions until the alpha score is as high as it can get and the remaining set of questions is as reliable as it can be. The reliability is better as the alpha approaches 1.
