Hello and welcome to Milestone five. When you move to working on your final prototype, this is not going to be a rebuild from scratch. You're going to stick with the same prototyping tool that you worked with before and you're going to stick with the same prototype that you already worked on for your medium fidelity prototype, and you're basically going to be editing and improving that prototypes. You don't need to start from scratch. For your final prototype, you're again going to widen the focus of the functionality that you're prototyping. You're going to add two or three more tasks. These could either be key tasks that users need to accomplish in order to achieve their goals with the interface. Or if you feel like you've covered those key tasks, these could be more maintenance or bookkeeping type tasks. Things like creating an account, logging into the account, recovering a lost password, configuring settings, and things like that. You're going to be trying to create a complete interface at this point. So you need to cover all of those different types of tasks for this interface, you want to polish this up, make it look a little bit nicer, add a bit more color, a bit more layout, a bit more graphical pizzazz. If that's something that you are comfortable with. You don't necessarily need to, but you want to try to make this as complete an expression of your ideas about this design as you possibly can. It should cover all the functionality that a user would need in order to be successful with the application. When thinking about the user tests that you'll be planning, this should be very familiar. It probably will be very similar to the user test that you performed a couple of milestones ago. The only difference being that you need to plan to recruit new users. You should not reuse participants from your previous user test. You could reuse participants from your needs finding study if they didn't participate in the first user test. The key is the participants in your user tests need to be seeing the system for the first time. That way, they haven't already figured out the logic of the system, they're coming to it with fresh eyes, and that's really what you want to see in this kind of a user test, one other note about the user test. You have the option in this instance to investigate using remote technologies like usertesting.com to conduct at least some of your user testing session. That's a great skill to have. I would recommend taking advantage of it if you are interested in pursuing that, but you need to check it out and make sure it's going to work with your setup, it's going to work with the prototyping tool that you've chosen and so forth. If you plan to conduct at least some of your user test sessions in person, you're also going to need to investigate recording approaches that you can use for in-person testing, screen capture software, video recording software, all of these kinds of things and we will be providing some resources for those on the discussion forums and on the site. Okay, you've put a lot of work into this project so far and we're getting to the point where you can see the end, it's not far away. Keep working, keep going forward. Make those prototypes as complete as you can, and I'll see you again for Milestone six.
