problems with current process
Problems with Current Process
  • Miscommunications
  • Schematics (Drawings) vs. Real Field Conditions
  • Human Resources – Age Gap within the Designers
slide7

Cause & Effect Diagram

  • Identify the possible root causes, the basic reasons for a specific effect, problem or condition
  • Helps determine root causes
  • Increases process knowledge
  • Identifies areas for collecting data
  • Analyze existing problem

Recommendations
  • Miscommunication
    • Project Checkpoints strategically placed within certain stages of the DEP.
  • Schematics vs. Real Field Conditions
    • A full-time Designer at the station to upgrade existing drawings to current field conditions
    • Current Designers assigned to on-going projects will update drawings during construction
recommendations cont d
Recommendations (cont’d)
  • Human Resources – Age Gap
    • Hire retirees to give seminars/classes to incoming and present employees
    • Pair experienced designers with inexperienced designers
conclusion
Conclusion

If the necessary changes are implemented:

  • Detailed training guide for new employees
  • Duration of DEP would be decreased and run smoother.
  • Department would spend less than $8 million on outside services
