I will like to know what do you undesrtand about strategic design.
Design that is derived from a design strategy. So you should be asking what design strategy is.
Recently it has been used a lot by businesses in the context of having Design deployed at more of a strategic level, rather than a reactionary level. Meaning getting design involved closer to the actual decision making process. IE Strategic planning, Strategic partner, etc.
From a corporation, it is a way of making it look like they are trying to delineate product through innovation and design.
From a consultancy, it is a way of trying to sell their services as early as possible in the development process.
Either way, it can be a winning situations as design always sees the issues differently than the CEO’s and the marketing/merchandising departments do.
