Abstract
Business administration has been changing with great revolutions in the last decades and, by the way, the quantity and its problems complexities didn't stop growing. After decades of competences accumulation by the companies to answer to the more dynamic and diversified demands, Innovation has became the great proactive competence craved by the surviving companies. Then, this research analyses, through mathematical models, the economic performance of the two different Concurrent Engineering strategies. Concurrent Engineering is one of the most efficient methods of innovation process management nowadays. The two strategies are known as Point-Based Concurrent Engineering that drives the development process through improvements from only one initial concept and Set-Based Concurrent Engineering that manage the product development with a process that begins with multiple concept alternatives and converges to the best one. Mathematical models were developed with the goal of comparing the economic performance ofthe product development, as managed by Set-Based Concurrent Engineering or by Point-Based Concurrent Engineering, for projects with different technical uncertainty and complexity leveis, different development costs and in the presence of different product sales opportunity window extensions. The most important result may be the regions mapping that are defined from well known project conditions, to what each one of the strategies get the best economic result. This mapping enables management implies because it allows the immediate association of business environment and considered project conditions with the strategy that will take the best result. We found results that confirm the idea, in the literature, that Set-Based Concurrent Engineering has a better potential to manage projects with higher leveis of technical uncertainty and complexity. Another interesting result is one that shows that Set-Based economic performance is also superior to projects with lower leveis of technical uncertainty and/or complexity with higher development costs in the presence of relatively small extensions of the product sales opportunity window.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
