The Importance of Excel
We software guys complain about this all the time, but Excel completely permeates the corporate world because it:<p>- is universally available (who in an office building DOESN'T have an Office license?)<p>- can be "Programmable" to the extent that it needs to be.  You don't have to start with code.  Formulas and conditionals are great for most things.  People usually ease into Macros gently.<p>- produces a format that is sharable.  People "fork" Excel spreadsheets all the time.  It's not pretty but it works.<p>- gets the job done.  You want data entry with some calculations and maybe a few if-then rules here and there?  What's better than Excel?<p>In a corporate environment, often the best way to get things done is to <i>circumvent</i> the official software and just write something that works.  When <i>we</i> do it, we call it an elegant hack, but when guys in suits who went clubbing last night do it, we call it a terrible, amateur travesty that should be replaced by PROPER code as soon as possible.<p>And you know what, eventually that happens.  Very rarely, an incredibly useful Excel spreadsheet will be replaced by an even more useful (and reliable) piece of custom software that also adds tons of value to both the users and the organization.  But I've worked in corporate consulting for years; can you guess how often this happens?  I'd wager it's less than 40%.<p>No, what typically happens is that an analyst or software dev notices someone's cool spreadsheet and says "hey, I can make something that does this job, but it'll be a LOT faster and I'll put the data up in the cloud and multiple people can access it at once and..."<p>And that sounds great, so they get a little budget and a project is born.  Most of us who have been there and done that know what happens next: higher-level stakeholders get involved, broader objectives get defined, more team members are brought on, timetables are established, results are "metricized", paradigms are going to be shifted, etc.<p>Rarely does a piece of software escape from this process that is as genuinely useful as the spreadsheet which spawns it.  Often, rather, it gets delivered 6 months late.  It crashes all the time.  What used to be one simple input field is now a whole page with checkboxes you have to check and sub-objects you have to define.  The end result might look a little prettier but that cool Infragistics graph is locked inside the program and can't be shared like the old Excel report because no one hooked up the "export feature".  People are getting upset.  Everyone hates this program.  But we have to use it, it's mandated by corporate.<p>Meanwhile, a talented new guy comes on the team and notices what a bloated piece of crap this software is.  He wonders why no one has written a little Excel sheet to get around it and REALLY get some work done...<p>I know I'm being cynical.  And look, I GET that rogue spreadsheets can turn into productivity-damaging unseen business risks.  But until the corporate "software project" culture understands why it happens and why people are often far happier with their clunky spreadsheet than with your shiny WPF app or web page, I don't think this problem is going to go away.
