Email from a department mgr regarding a sharepoint site we inherited (lots of custom javascript, XLS, etc, stuff we didn't write)

Dan: "The department filter isn't showing up when I select the 'Logistics and Support' department. Was this caused by the changes you guys made? Its causing a major disruption in our processes and need it fixed ASAP."
Me: "Those changes went out almost two months ago and all the filters were working fine, at least that is what you told me when you tested it."
Dan: "I thought so, but its not working. It has probably been broken ever since you made those changes so I filed a corrective action ticket against your department for not following the documented deployment and testing processes"
Me: "Really? We've been over this. Its your department that is responsible for that sharepoint site. Previous developers hacked javacript together to make it all work, but I'm sure its something simple."
Dan: "Great. I'll start putting together a root-cause analysis to determine which of your processes we need to address."

Start looking at the javascript and found the issue..

if (dept === "Logistics & Support") {
$('deptFilter').show();
}
else {
$('deptFilter').hide();
}

Me: 'Found the issue. Did you rename the logistics department?'
Dan: 'No'
Me: 'To show or hide the filter, the code was looking for "Logistics & Support", someone changed the title to "Logistics and Support"'
Dan: "Well...I guess I did that yesterday...but I didn't change the name, just that stupid character. That shouldn't make any difference."
Me: "I can fix that right now. Are you going to need more information for your root cause analysis?"
Dan: "No, I think we're good. Thanks."
