This document summarizes a presentation about best practices for implementing and managing fieldbus and HART systems over their lifecycle. It discusses that fieldbus and HART have a large existing installed base and are growing. While installed costs savings may be small, the primary benefits are in reduced lifecycle and operational costs through improved process control, asset utilization, and maintenance efficiencies. However, many companies have not fully realized or are unsure of the long-term economic benefits, and it can take over a year to achieve full return on investment from fieldbus and HART systems.

- 15. Proper Training & Education is essential No single standard available Lack of management buy-in Lack of employee buy-in Lack of field workforce knowledge Increased training costs Strongly Agree Agree Insufficient host system functionality Neutral Disagree Multivendor interoperability issues Strongly Disagree Not proven in mission critical apps Initial cost is too high Lack of supplier support/commitment Not enough products available 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Lack of field workforce knowledge is key limiting factor in fieldbus implementation
- 16. Up Front Planning is Essential to Success ♦ Get the Involvement of the Supplier and Partners ASAP ♦ Avoid the “Now that it’s Installed, What do we do Now?” Syndrome ♦ Lifecycle Benefits are Determined in the Planning Stage ♦ Need to rethink worker roles
- 17. Employee & Management Buy In ♦ Employee buy in must reach from maintenance to operations and engineering ♦ Management buy in is essential, justification of the technology must match overall corporate objectives ♦ This is where training and education begins. Maintenance personnel could view fieldbus/HART as a threat. Show them how it will make them do their jobs better!

- 23. Conclusions and Recommendations ♦ There remains a substantial installed cost benefit to fieldbus technologies, but the real value lies in the operational and lifecycle cost phase ♦ Many end users are not realizing the optimum benefit that fieldbus and HART technology can provide ♦ Training and education are essential. Applying essential fieldbus as a mere replacement for 4-20 mA guarantees project failure and zero ROI.
