Logistics have been especially tricky. We have been trying to ship the components we have ordered from various sources to one central location to be shipped out, in order to ease shipping costs. It's been difficult when some components are late and the shipping carriers only leave on specific days of the week. Our entire package of components would have arrived a week after our pilot study was supposed to begin had we not caught on that there would be extra delays from customs! So it is air-shipped, and will now arrive before our study.
We can only do so much planning. We may think that we have imagined enough scenarios to keep us on track; however, there is always something unforseen, and oftentimes the best way to avoid those are to give enough time to oneself.
Overall, we're very anxious and excited for the study. We don't know how it'll turn out, but we're very sure that it will be insightful.
