The Benefit of Finding Problems Early in a Project

Peter H. Feiler and Jorgen Hansson from the Software Engineering Institute (SEI) have compiled and published some interesting statistics that point to the benefit of finding and fixing bugs early in a software development project.

There is a huge benefit to finding and fixing problems early.

Here are some of the most remarkable findings:

  • 70% of faults are introduced in the early stages of a project lifecycle.
  • But, only 3.5% of faults are found at that stage.
  • 80% of faults are actually only found in the later stages of a project’s lifecycle.
  • The cost of fixing faults in the early stages is 2.5x.
  • The cost of fixing faults in later stages is 16x or higher.

According to the research you can save yourself over 600% on repair and rework costs on a project by finding and fixing problems early.

While this data is specifically for software development, the conclusion rings true for projects of all sorts, including marketing projects, creative work, manufacturing or research projects.
