[…] as the saying goes, a little knowledge is a dangerous thing. Much as I’m not a marketing professional just because that witty tweet I wrote that one time got 75 RT’s, you’re not an engineer because you sent an HTML email that looks great in all email clients except Outlook.
Let’s say you wrote an email template that you already sent out to some users, and you want to add a page with the same information to your website. Or you wrote a SQL query that you use for some analytics purposes and now you want your engineer to add something similar to the product – maybe as part of a dashboard, or maybe as a core feature. Easy, right? You already did the hard part!
Not necessarily. That query might be fine for one-off use, but may not be suitable for a production environment. Here are just a few reasons it might not be that simple.
