>utilize prototypes as a method of proving features and concepts before committing them to your design. Third, don’t be overly ambitious in your design. Be reasonable, and take into account your schedule and budget before adding something to your design. Building off of that, don’t be overly optimistic with your scheduling. If you make an estimate that initially feels optimistic to you, don’t give that estimate to your stakeholders. Revisit and reassess your design to form a better estimation.
