We can easily recognize the effort, resources, and technology that went into building both the Concorde and Space Shuttle Columbia. However, not everyone can understand and appreciate the little things that are essential for the success of the mission.
Those of us who are in software and information technology understand how projects are done, what makes them succeed, and the resources (time, effort, and money) that goes into them. Project components are frequently complex and can consume major resources, so we tend to focus on these larger aspects when we review what is critical for the success of the project. However, focusing too much on the big tasks makes it easy to overlook tasks or components that appear simple, inexpensive, or less glamorous.
