Excessively Complex or Customized Equipment:
Many operators are wowed by system specialists demonstrating all the capabilities of their SCADA system. After installation, the system is too complex for them to understand, operate and support. What you will have is a very expensive system running at minimum while the operator continues to work the old habits. The only recourse is to purchase expensive training and/or service contracts, which do not always guarantee prompt and professional service. Some SCADA systems have been shut down for months while waiting for a single source of technical support to arrive. Keep it simple wherever possible.
