5 Results of Hypotheses Testing 85
. 85 5 Results of Hypotheses Testing In this chapter the results of multiple regressions for testing the hypotheses on the local-level relations (intrateam as well as extrateam) – derived in the second and third chapter – are presented and discussed. Based on the information-processing theory, distinct influences of relevant problem-solving communication variables on team effectiveness and team efficiency were stated. These communication variables, in turn, were hypothesized to be dependent on systematic design principles applied to reduce the complexity in the NPD process. According to the discussion in the previous chapter, each hypothesis is tested separately for the two studied MOMT projects within one sample. For every hypothesis testing the control variable team size was applied. First its potential influence on the different dependent variables studies was tested (model CV). It was then tested together with the variable that is hypothesized to have an influence. For testing a curvilinear relationship, both the linear and the quadratic term of the explanatory variable were included in the regression model. At first a closer look is taken at the influence of problem-solving communication on team performance – team effectiveness and then team efficiency – (Chapter 2 hypotheses). In the section thereafter, its dependence on systematic design principles (Chapter 3 hypotheses) is addressed. In addition to the quantitative questionnaire data, qualitative team leader interview data was also analyzed. A summary on these local-level results is presented in Section 5.3. 5.1 Communication Team Performance As discussed in the second chapter, team performance in MOMT projects is dependent on diverse...
