Consistency is created across all items created, appropriate imagery is chosen and the brand is always at the forefront of my designs. Even though I am quite often designing for my colleagues, I still view them as 'clients' and take on board their suggestions but also tell them straight up when there may be better solution to what they first thought was needed. Providing different options also helps them to decide on what they do and don't like, and often we end up combining elements from one design with another to create the finished piece.
Keeping on top of my design process doesn't necessarily benefit others in the business but it is always good to see where a design has come from and revert back to previous ideas.
