What-if technique

The team leader should possess an engineering degree or equivalent. He should have a minimum of five years petroleum or related industry experience and be trained or experienced in the conduction of HAZOP or What-If techniques. A leader will typically have had three to five days of classroom training and have actually trained as a leader for one or two actual review sessions. A Leader should possess a congenial personality yet still be authoritative to the other review team members. Preferably the Team Leader... 

One effective systematic method, a variation on which will be outlined further in this book, is the SWIFT or Structured What-If Technique. SWIFT is a systems-based risk identification technique that employs structured brainstorming, using pre-developed guidewords or headings in combination with prompts elicited from participants (which often begin with the phrases What if... or How could... ), to examine risks and hazards at a systems or subsystems level [1]. The technique was originally developed as a simpler alternative to HAZOP (see Sect. 13.6.2).

In either case, a hazards analysis should be performed with the What-If technique probably being the preferred method. In the case of the plant that is being mothballed, the analysis will include items such as the following ... 

Depending on the nature of the policy change or budget cut, there may be suitable checklists which can be utilized to evaluate this type of change. Otherwise a brainstorming or What-If technique may be appropriate for this type of risk assessment. Refer to Appendix A for information about risk assessment tools.

The remainder of this chapter will discuss HAZOP and what-if techniques in detail and illustrate specific examples of how they are applied. Chapter 7 will address fault tree analysis and Chapter 8 will discuss failure modes effects and criticality analysis. An excellent reference manual for these techniques is the Guidelines for Hazard Evaluation Procedures, published by the American Institute for Chemical Engineers CCPS (2008). 

The what-if technique involves a group of procedures methodically and considering exanple. What if the reactor where not at situations can uncover potential problems, for single, small-scale processes, such as more rigorous HAZOP technique is used, formalized version of what-if.

Structured What if Technique (SWIFT) SWIFT is a systematic team based study to identify risks and hazards (lEC/ISO 31010, 2009). It employs structured brainstorming and forms an alternative to hazard and operability studies technique (Card et al., 2012, lEC/ISO 31010, 2009). 

There are several advantages and disadvantages of using the What-If technique. The advantages include ...
