Design is key to a project’s profitability and therefore increased PROFIT by DESIGN is the goal of improvements to the design process. Business requirements can be summarised as Better, Faster, Cheaper and considerable investment has been made in technology and methods for the design process to enable this. There is evidence to suggest that these investments have resulted in products themselves getting better but not necessarily produced faster or cheaper. A model of the design process has been developed which makes explicit its key elements. The six key elements or dimensions of the design process are: Analyse; Understand; Decide; Create; Capture; and Know. Investments in design technology may not be reaching their full potential due to a mismatch between the relative importance of the attributes of a good designer and the areas where investments have been made, leading to a potential loss of balance in the design process. This is compounded by failure to take a holistic view of changes to the process including mitigation of any downside. In particular the Create dimension, which is seen as the most important attribute of a good designer, has had the least investment and also is the most vulnerable because it is optional. In recognition of this fact, Rolls‐Royce is using the TRIZ methodology to provide designers with an improved capability. However it also is recognised that providing capability alone is not enough. The right motivation and opportunity are also needed, and this requires the appropriate organisational and cultural features to be in place. What is needed is a people centred process that is business driven and product focused.
