This overview of the concept of the 'technology readiness level' (TRL) is useful in the areas of innovation and technology development (we use it in-house at NRC). The idea is to distinguish between innovations that are still at the conceptual stage and those that are ready for production. Our MOOC technology reach 5 or 6, and did not receive project support to go further. Our personal learning environment software has reach level 4 in earlier prototypes and now we're trying to get it to 5 or 6, after which if it's successful we have the plan and commitment to go further. TRL is useful because it demonstrates the hurdles to innovation - it's not typically getting to step 1, as most people (I think) suppose, it's getting past the higher levels and into deployment.
