DQ 2 :Compare and contrast two change theories, and determine which theory makes the most sense for implementing your specific EBP intervention

Choose two theories that would give different advice about your intervention, because two that agree produce a comparison with nothing in it. Lewin's unfreeze-change-refreeze is simple and its value is the refreeze stage, which names the thing most nursing projects never do. Kotter's eight steps front-load urgency and coalition building, so it is the better fit when the problem is that nobody yet agrees a change is needed. Rogers' diffusion of innovations shifts attention from the organisation to the adopters, sorting them into innovators through laggards and asking about the innovation's own attributes — relative advantage, compatibility, complexity, trialability, observability. That last one is genuinely useful for a capstone, because it tells you to make the change easy to try and easy to see, which is concrete advice rather than a stage to pass through. Say which stage of each theory you would actually be standing in during your practicum weeks, because that is where the choice bites.

Then make the choice on the shape of your own intervention, and say why the losing theory loses. If your barrier is that people do not accept the problem exists, Kotter's urgency step earns its place and Lewin's unfreeze is too coarse to guide you. If the change is small, voluntary and spreading nurse to nurse, Rogers describes what will actually happen better than a staged organisational model. If the risk is that everything reverts once your practicum ends, Lewin's refreeze names your central problem and you should say so. Finally, answer the preceptor question honestly, including if the answer is no — many preceptors have run changes without naming a theory at all, and describing what they did and mapping it onto the stages afterwards is a genuinely good answer. What happened is more interesting than what was intended, so report the result rather than the plan.
