I just returned from an ASME (American Society of Mechanical Engineers) meeting in NYC. During my time there I discussed the concept of decision making maturity with three different groups and thought it worth writing about. Best to do in context with my career.

When I was trained as an engineer, I focused on how components and assemblies were shaped, manufactured and functioned. This element-centric view of the world is not at all unique to engineers. Businesses focus on documents, e.g. POs, recepts, memos, contracts, etc)

By the 1980s I became fascinated with the process of developing the elements. This process-centric view is recent. Sure engineers have studied and developed chemical and manufacturing processes for years, but the concept of product design processes and business processes is recent. As evidence of this, in 1990, I wrote an engineering text book about how to progress from customer need to produced product. I debated long and hard about what to title it. I finally landed on "The Mechanical Design Process", a title that proved to be right on the mark (note that its 4th edition will be out in January 2009). The use of the word "process" in the title was problematic because it was only beginning to be used to discuss product evolution.

In the early 1990s my research was about how to capture and manage the evolution of products, the rationale for form and function. This was process-centric, but not getting anywhere. In about 1995, it dawned on me that "design is the evolution of information, punctuated by decisions". That started me on a decision-centric view of the business and technical worlds.

My maturity from element through process to decision is being taken by industry. While in NYC I met with a PLM (Product Lifecycle Management) guru. PLM grew out of CAD (Computer Aided Design) which was all about parts and assemblies - element-centric. PLmis currently focused on the process, i.e. the lifecycle of products. I have been trying to sell decision-centric capabilities into PLM since 2001 with no success. The push back has always been "we aren't ready for that yet" and they weren't. Now there is the beginning of interest. The product development industry is maturing through process to realize that business and technology progress is punctuated by decisions and it is the quality of those decisions that determine the product and business success.

Further, when I talked about this decision-centric view of the world five years ago to industires, audiences had no idea what I was talking about. Now I get good awareness and it is building. There is yet hope for "evolution punctuated by decisions".
