Who is counting on your trusted system?

Jeremy Roberts over at Cloud Productivity posted an article about a challenge he encountered with not sticking to his new Evernote based paperless system.  Now while we've all had problems with our own systems, that's not what struck me about his post.  To quote Jeremy:

 The wife is also dependent on my system...

This is a great example of understanding the expectations around your solutions as you work to develop them.  While we may be spending time to make ourselves more productive it is critical to also remember who else may be counting on what we put in place.  A trusted system must be trusted by everyone impacted by it, not just by it's immediate user.
As you develop your own solutions always remember that the success of any system is partially about managing the expectations placed on that system...not only by you but by the others who will count on it equally.
