While the lead user methodology has proven to be very successful, select literature highlights some product development scenarios in which the Lead User method may be less effective. For example, the following was pointed out on October 14, 2007 on “TechITEasy.org”:
"Highly secretive industries where lead users may not feel comfortable or may not be able to disclose information and knowledge are not suited for this [lead user] process;"
"The lengthy [nature of the lead user] process can prevent this methodology from being applied effectively in industries with really short term innovation cycles or where quick turnaround from research to market delivery is required;"
“The [lead user method] LUM is better suited to meet the needs of the industrial goods market rather than consumer goods market as lead users of industrial goods can typically be identified more reliably than lead users of most consumer goods.”[1]
Literature also suggests that an additional obstacle to the adoption of this kind of process is related to a general resistance to innovation and / or change that can be found in typically bureaucratic organizations; these organizations tend to resist disruptive changes in processes which many force the company to evolve, (although this is exactly the purpose of such an approach). While the lead user methodology can reliably lead to breakthroughs, adopting the approach can be difficult for some organizations and on the whole, the technique itself is useful to the extent that the product and / or service under study is lead user friendly (i.e. if it’s not a top-secret or quick time-to-market idea).
