The contribution of the personal characteristics and skills of the feeding team to the intervention was important and may be challenging to replicate.
A strict standardization of telemedicine interventions may thus prove difficult and the intervention may be challenging to replicate and generalize across settings and studies.
Even the most successful of these small-scale projects often fail to be mainstreamed into large-scale operations, because experimental trials generally use many resources that are challenging to replicate in large-scale operations.
While there may be challenges to replicating Costco's formula its customers are relatively wealthy, and it gets much of its revenue from the sale of memberships—Haley-Lock doesn't believe that there's "anything unique to the Costco model".

In spatially and temporally replicated trials from 2007 to 2009, cattle were challenged to eat sagebrush.
This bacterium is challenging to isolate and cultivate, as it replicates in short lifespan cells (i.e. polynuclear cells), which rapidly undergo autolysis after sampling.
Despite the benefits of orthotopic systems, they can also be quite time consuming and challenging to replicate as cell inoculations are typically conducted endobronchially, requiring skillful precision and practice.
Third time out, he and producer Alex McGowan have not only nailed the live act, they've gone further, creating a monster that could be a challenge to replicate on stage.
Three weeks after the first or second immunization, the mice were challenged with replicating viral reassortants belonging to H5N1 clade 1 (VN1203, HK213) or clade 2.2 (IND05) as well as with virus Dk/Sing/97 (H5N3).
