Let’s compare your new custom software project to your dream home.  You have some ideas on what you’d like:  at least 4 bedrooms, high ceilings in the family room, a finished basement, etc….  What you’re not thinking about is the configuration of pipes under the kitchen sink or the gauge of wiring behind the walls.  In fact, if you did design each of these things explicitly, you run the risk of unknowingly adding unique or incompatible options to the construction of your home when common options are readily and easily available.

It’s a similar situation when creating custom software.  We’ve found that our custom software projects often follow common patterns; eliminating the need to “reinvent the wheel” for many of the pieces of a new project.   For instance, the login process for a web application has been widely standardized and there is usually no need to re-architect how this works.  Maybe just an adjustment here or there.
