Onur Cobanli explains:
Design usually requires iterations to improve and built upon existing works, usually the more iterations and refinements; the better the design, and for each iteration and refinement you need more time. If you have a good design you will want to take your time and do the due diligence to refine and improve it. Invest in your good design and make it better, make it a future product available today, get rid of its issues and errors before releasing it to public.
