The importance of soft skills in IT

Soft skills are crucial to being a successful developer in the IT industry.  Some of the soft skills I've found beneficial in my career are:

• Being a good communicator.  It's not just about talking, but listening as well.  Dirareah of the mouth is never cool, especially when a job needs to get done.  Strive for mutual understanding in a conversation. Communicating in the IT world isn't just limited to talking and listening though.  
• Having the discernment to know when to write an email versus actually talking to a person is important as well. I do not recommend doing all your communication through email.  Communication in emails can easily be mis-understood or mis-construed and take on an entirely different meaning and tone than you originally intended.  Emails are great for documenting decisions.  
• Make sure that the content of your email deals with the subject you've put in  your subject line.  For example, having a subject line of 'Quote for project XYZ' but then talking about quotes for that project AND other projects in that email is bad news.  Send you quotes for the other projects in a different email with a more relevent subject line (I know this from experience).
• Developing relationships.  Extending communication a bit further and actually developing relationship with people in the office is huge as well.  Questions like "How was your vacation?", "Where are you going on vacation?", or "What did you do over the weekend?" are great for this. When you've got a relationship in place, there's trust.  Many times I've been granted exceptional privileges and become more productive in my work because I've had a relationship with a key person who trusts me.  These relationships can also help in the future as well when you are looking for that next gig.
• Having patience.  Whether it's letting somebody else go to the front of the 'line' for access to production, or having forbearance when dealing with a difficult client, patience can go a long way to strengthening that 'trust' in your relationships.  Sometimes work (or working with clients) in IT can get frustrating.  Things I do to help me step back and get some perspective are:

• go for a walk
• find something else to do for a while
• talk to someone - use them as a sounding board
• take a day off or go on vacation

• Positive Attitude. I like to keep my workplace fun, interesting, and upbeat.  To promote this around me I'll sometimes:
• Bring baking from home to share
• Audibly rejoice in small victories (getting a solution migrated and compiling from VS2005 to VS2010 for example)
• Write thank-you notes (either hard or soft copy) to others who help me
• Encourage people who are down. We had a large project I was helping with and the lead was concerned that between the time and the technical challenges he had, he wasn't going to be able to finish on time.  I believe he could and I told him so (and backed it up with my help).  In the end, he did finish.
• Being Flexible.  Generally, you are always working for a client.  Invariably, they will change their mind or want an enhancement.  Microsoft will upgrade their software, the US president will change daylight savings time one more time, the CTO will be convinced that Tibco will solve all the business problems again.  I've found that being able to take these changes in stride is crucial to maintaining my mental health (avoid being overcome with frustration).  It's all part of the territory - and frankly, job security.
