The notion of enablers and barriers is a very important research arena. Based on the comprehensiveness of our work prior to the questionnaire, a good set of both enablers and barriers has been identified. Several important issues need to be addressed. Which enablers or barriers seem to actually have the most negative or positive impact? Second, it would be useful to understand why a specific determinant is an enabler in one situation/company and a barrier in another. How can one turn a barrier into an enabler, which we learned from both case studies and the Delphi study to having been done in many firms? Finally, as comprehensive as this list is, over time some new issues influencing logistics measurement are likely to appear. We need to be able to identify when that happens, especially barriers, and learn how to deal with them.
Since a big issue today is return on investments, research on what measures link to behaviors and activities that result in better financial returns is a priority. A theme in both the Delphi study and the case studies is the problem of actionability of the measures. Having the measure is one thing, but being able to use it to direct specific actions and then getting a return on those actions is a big issue. Are there any particular measures that have led to successful actions that provide greater potential returns?Tracey et al. (2005), Lockamy and McCormick (2004), and Hofman (2004, 2006) have already provided some insights into this problem.
