We have learnt over the years that great work takes time. Those with lots of experience can perhaps take less time, but time is necessary to take what you create from good to great.
In our experience, companies often try to rush through the design and ideation phases. This is a dangerous mistake and often the project must backtrack in order to correct its direction. It takes a lot of additional time for the work to be done again or fixed.
The old saying "Measure twice, cut once" applies when designing products and services.
