Growers took red and yellow carrots to create the orange root, just like using a paint box. Before then, carrots were purple, red, white, green, yellow, or black. Carrots are readily available in five main colors in the stores these days: orange, red, purple, white, and yellow. Each color has a different health benefit.
A pilot study, pilot project or pilot experiment is a small scale preliminary study conducted in order to evaluate feasibility, time, cost, adverse events, and effect size (statistical variability) in an attempt to predict an appropriate sample size and improve upon the study design prior to performance of a full-scale research project.
The Planning Phase is the time when the project team translates the initial vision/scope from the Envisioning Phase into practical plans on how to achieve it. The purpose of the Planning Phase is to define the solution in detail along with the approved project plan and schedule. This work includes creating a functional specification, developing the solution architecture and design, and preparing cost estimates.
