ISA-18.2 includes training for operators in the Implementation Stage (Clause 13) and refresher training for operators in the Operation Stage (Clause 14), and training for advanced alarm systems (Clause 12). Clauses 13 and 14 list specific items that should be included in the training.
The ASM document has seven guidelines on training listed in the last section of Table 1. These seven are more general in nature, but encourage a broader operator training experience through the use of "what if" training (Guideline 3.3), situation support tools (3.4) and the use of dynamic simulators (3.7). Additionally the guidelines specifically cover training of the design personnel (Guideline 3.6) and the rationalization team (Guideline 3.2).
Summary and Conclusions
Generally, each ASM guideline is addressed in some way by one or more ISA stages, though ISA-18.2 describes the specific life-cycle stages in more detail than appears in the ASM guidelines document. Taking the other view, each ISA-18.2 stage has one or more ASM guidelines that relates to that stage, though ASM guidelines often make recommendations beyond those found in the ISA standard.
Thus, in the author's opinion, the ISA-18.2 document is the better reference for definitions and for work process details―in some ways a more succinct document for analyzing the impact on your plant; i.e., to plan, fund and execute. The ASM Consortium document is the better reference for background, rationale, business justification and site examples―and being less constrained, enables it to have a slightly broader scope in its recommendations.
Both documents have their recommendations prioritized―ASM using its three numbered priorities, and ISA-18.2 effectively using two―with its "shall" statements and "should" statements. The practitioner can take each document's essential practices and work from there. For example, a good starting point is the ISA-18.2 "shalls," along with the background and added considerations of the ASM priority 1 guidelines.
In conclusion, these two works, developed somewhat independently, but with common motivations and goals, complement each other nicely because of their different perspectives and approaches. Both documents will provide control system engineers and the operating team good guidance and structure to work toward the objectives and targets laid out by EEMUA Publication 191.
