When working in research, there is no standard design document when conducting an experiment as experiments are always subject to change. Let’s take coming up with a new formulation for a hydrogel for example. Once we come up with an idea on what ingredients would be needed, we test out the formula. While conducting this experiment, it is imperative to have a lab journal on you at all times, documenting your observations. If the hydrogel is not up to par, taking your observations, you create a new formula with addition of ingredients and adjusted quantities. This new formula is now the updated formula. Most researchers have multiple drafts of their formula’s and compile it into one document, showing the evolution of this hydrogel, acting almost like a DHF.
