Details matter and you're responsible for them! But not at Verizon.

Details and quality matter.  If you don't pay attention to them you'll build terrible software.   It's your job as a team lead to drive quality.  If you think that modern software developers will not commit obvious mistakes, I beg to differ.

Here's an example of what I mean.  Verizon reports my data usage as 1024 MB/month.  This is clearly wrong because there's no way I use exactly 2^10 MB (or 1GB) every month.  What's more, they report my allowance in MB as (2) when it's actually 2GB. 


This table is wrong because:
  • The data are wrong.
  • The scales are wrong - not out of scale, but literally wrong.
  • They have duplicated data (repeating total data used) for no clear reason.
  • The alignment of the numbers is off - you put the ".00" on the right, so that people can compare big numbers by length.
  • There's too much precision.  Do I really need six significant digits on my data usage?  No.  Remove the decimals at least.
  • All of the fonts are bold (save for the repeated data, which shouldn't be there) for no clear reason.

I'm not sure who's responsible for shipping this - but it clearly should never have been released.  It's functionally broken and broken at a design level.

The Verizon Wireless Account Analysis chart is no better:



This chart is a disaster and an example of how you should NOT build a chart if you wish to communicate clearly.
  • The month label has exactly the same font treatment as the months - so it reads as "January month,"  rather than a label.   
  • Rather than putting the scale on the left, by Data (in MB) they put it in big bold font on the RHS.
  • They put the title in a Tab, when there's clearly no other tab to select. 
  • They've left huge amounts of whitespace by putting the legend on the bottom instead of top right, like most legends.  That's a nit, but still.
  • Why is this weird window size like this, so that there's a huge gray border and also tons of whitespace beside the chart?
  • Why did you capitalize megabytes?  They are not a proper noun, they are a unit of measure, like inches.
I suppose I should not expect much from a company to which I pay only $xxx per month - but a reasonable team lead could identify and fix these problems in just a few minutes.

Things like this make me want to short Verizon, but I think their fiber, wireless, and cable operations are better aligned than their competitors, so I suppose I have to forgive these painful mistakes.
