pp77:"staff members' assessment of their project's coordination strongly correlates withg customer satisfaction with the software development company and the software it produces. [...] senior managment's assessment of the quality of projects is unrelated to other mesasures of project success. [...] "
p79: "older projects are more certain....coordination easie to accomplish. [...] use of formal provcedures is not assoicated with a better intergroup coordination once one controls for the conditions under which they are used. [...] the beneficial effects of interpersonal networks were most pronounced when projects were uncertain. [...] Senior managers assessments of the quality of the software process and product that they managed was unrelated to either the staff's assessments of the success of their project's coordination, client's satisfaction with the company, or the software quality metrics.[...]"...They judged older, self-contained, projects with formal communications as more successful.
