EZ-Xpert saves you time and money at every step of the life cycle. Compare the costs of implementing a 500 rule system with the traditional approach and the EZ-Xpert approach.
Assumptions:
Knowledge Engineer fees: $2500 per day
Rules per day: 10
Expert salary: $400 per day – $100,000 a year

EZ-Xpert Development Approach: The Expert learns EZ-Xpert in 4 hours. The Expert completes the implementation in 12 additional hours.
Salaries:  $800
Time: 2 days

Traditional Development Approach: At a rate of 10 rules per day, the Knowledge Engineer will require 50 days to implement the system. The Expert will typically lose 10 days of productivity.
Salaries: $129,000
Time: 2 months

Implementation savings:  EZ-Xpert implementations run hundreds of times faster than inference engines. You may be able to save $100,000 by implementing on a PC instead of a mini-computer!

Inference Engine Savings: Many industrial strength inference engines cost from $10,000 to $35,000 per CPU.  With EZ-Xpert, there is no inference engine to purchase, license, learn, and support.

Maintenance: When the system needs updating, the Expert can make the changes in EZ-Xpert and generate a new executable in minutes. In the traditional approach, the Knowledge Engineer must acquire the new knowledge, code it, and verify it. Hopefully, the original knowledge engineer is available.
