Since, in this phase the code is produced so it is the main focus for the developer. The design phase turns the software specifications into a design plan. This information is then used to plan the basic project approach and to conduct product feasibility study in the economical, operational and technical areas. Processes are identified along with any of the associated data they use or create. The requirements are divided into groups at the start of the project. For example, patients take their own blood pressure or heart rate, glucose level, etc. Instead of specialists handing artifacts to one another, and thereby injecting defects at every step along the way, agile developers are with full life cycle skills.
