INNOVATION CATEGORIES Category 1 Category 2 Category 3 Supporting Operations / Heritage BU Initiatives Exploratory Essential Support Of Existing Products & Operations Product & Process Extensions Platform Technology Development Exploratory Projects Transitioning to the work done by CIC & OI (you all have seen this before) 3 categories: Heritage (Activities that supports ongoing business), Business Unit initiatives on new product and process extensions, and work being done on big ideas that lay the groundwork for our future growth. The 2011 allocation of the $10 MM spend on these categories is shown here. Note that the total spend of $13MM includes the overhead cost of maintaining Libertyville. As you know there are robust processes within the company (Single point of contact for mfg, PPMT, and Business Teams) that manage and ensure alignment of the first two categories.. The return on this investment is …. USG CONFIDENTIAL
