The problems with traditional hard-coded or hard-wired rules include:

  • Duplicate rules must be coded & maintained in many systems

  • Rules coded once
  • Rules are isolated from code

  • Smaller applications make it easier to change and test applications
  • It takes days to change business rules --> Faster Time to Market
  • Lower Development & Maintenance costs
