Firms that can bring products to market faster can extract higher initial margins, can be more responsive to their customers, and will have products with longer sales lives. Critical Chain is a new methodology that applies Eli Goldratt's Theory of Constraints to project management in order complete projects faster and with greater predictability while simultaneously making more efficient use of resources. The Critical Chain method accomplishes this by building project networks with average task durations, aggregating buffer at the end of projects where it can absorb unplanned iterations and other delays, and de-conflicting resources, both within and across projects. This new project management methodology was researched by spending seven months on site with ITT Night Vision and applying the method to two product development projects. In addition, benchmarking studies of previous product development efforts at the same site and of another lead user of the tool were conducted to provide both qualitative and quantitative comparison data. Critical Chain appears to minimize schedule risk while simultaneously minimizing project duration, and has the potential to improve both communication and employee morale.","abstract_html":"In an ever intensifying global competitive market, the management of projects, particularly product development efforts, increasingly is one of the few areas which can produce a sustained competitive advantage.
