CHAPTER: 8
ANALYSIS AND RESULTS
8.1 Addressing Common Method Variance
8.1.1. Harman’s Single Factor Analysis
Harman‘s one-factor test, ex post statistical tests, was conducted to test the
presence of common method effect. All the variables were entered into an exploratory factor
analysis, using unrotated principal components factor analysis, principal component analysis
with varimax rotation, and principal axis analysis with varimax rotation to determine the number
of factors that are necessary to account for the variance in the variables. If a substantial amount
of common method variance is present, either (a) a single factor will emerge from the factor
analysis, or (b) one general factor will account for the majority of the covariance among the
variables (Andersson & Bateman,1997; Aulakh & Gencturk, 2000; Greene & Organ, 1973;
Krishnan, Martin & Noorderhaven, 2006; Podsakoff et al., 2003; Podsakoff & Organ,1986;
Podsakoff , Todor, Grover & Huber, 1984; Schriesheim, 1979; Schriesheim, 1980; Steensma,
Tihanyi, Lyles, & Dhanaraj, 2005).
Results showed total 23 factors have emerged with Eigen value > 1. The first
general factor accounted for 29.42 % of the total variance. Results from independent t-test and ex
post statistical test shows no evidence of common factor, hence no common method variance is
present within the responses of participants.
8.2 Hypothesis Testing
Basic descriptive statistics for the data are shown in table 8.1 and the correlations
between the independent variables along the reliability (α) for this study are shown in table 8.2.
Cronbach‘s alpha for the nine items of knowledge sharing measure, eight item mutual trust and
seven item team performance was 0.908, 0.890 and 0.887 respectively.
8.2.1 Measures of Deviation from Normality
Skewness measures the symmetry of a distribution means up to what extent a
distribution of values deviates from symmetry around the mean (George and Mallery, 2009;
Hair, Black, Babin, Anderson & Tatham, 2006). A value of zero represents a symmetric and
evenly balanced distribution. A value between -1 to +1 is considered excellent for most
psychometric purposes (George and Mallery, 2009).
Kurtosis is a measure of the peakedness or the flatness of a distribution when
compared with a normal distribution (George and Mallery, 2009; Hair, Black, Babin, Anderson
& Tatham, 2006). Like normality, a kurtosis value near zero indicates a shape close to normal.
As with skewness, a value between -1 to +1 is considered excellent for most psychometric
purpose (George and Mallery, 2009).

However, in the presence of mutual trust the process get accelerated and team performance
increases with accelerated growth pace.
8.3.10 Results for mediator effect of knowledge sharing on team performance
Hypothesis 10: Knowledge sharing mediates the effect of, (a) organizational characteristics, (b)
job characteristics and (c) individual characteristic on team performance
In order to test hypothesis 10a, 10b and 10c, the mediated regression analysis was
performed. In order to test the mediating role of knowledge sharing, individual dimensions of
organizational, job and individual characteristics were tested against the team performance.
Analysis showed beta coefficient values for organizational, job and individual characteristics as
0.265 (0.001), 0.043 (0.001) and 0.715 (0.001) respectively. It means that knowledge sharing
mediates the overall process. Based on the extant of mediation (in comparison to the non-
mediated effects), the mediation was termed as partial, full and partial for organizational, job and
individual characteristics respectively. Before analyzing, the data was tested against multi-
collinearity. The overall model fit values were turned out to be 0.622.

a. Dependent Variable: AVGKS
Above results were tested using multiple regression analysis. The regression
results for testing this hypothesis are shown in table 8.20. Analysis showed standardized beta
coefficient value along with standard error. The reported values were in support to the previously
reported bi-variate correlation values. The result showed VIF values well under the suggested
range. Overall the model fit adjusted R square value is 0.574. The summary result for the overall
model has been shown as in the table 8.24. Result supported the proposed hypothesis except
hypothesis 1b and 6e wherein formalization and task significance have been found non-
significant in the proposed model.

8.6 Structure Equation Modeling
The main effects model was also explored using structural equation model. The
structural model with the relevant standardized regression weights is shown in Appendix E. SEM
takes a confirmatory approach to test the dependence relationships and accounts for
measurement errors in the process of testing the model (Byrne, 2001). Further, SEM uses both
observed variables (indicator variables or in other words the items for the construct of the
measuring instrument) as well as latent variables (the underlying concepts represented by the
indicator variables or items). Assessment of model fit in SEM is done through various fit indices.
There are three major groups of goodness of fit measures. These can be classified as absolute,
incremental and parsimonious fit indices. An absolute fit index assesses how well the theoretical
model fits the data. Some of the absolute fit indices are the Chi-square or the ratio of Chi-square
to degrees of freedom and the residual based fit indices such as Root Mean Square Error of
approximation (RMSEA). The Chi-square/df ratio of 2 or 3 is taken as indicating good or
acceptable fit (Bollen, 1989; Gallagher, Ting & palmer, 2008; Schermelleh-Engel et al., 2003),
although this measure is highly sensitive to large sample sizes (Bollen, 1989). The RMSEA
measure is actually a badness of fit measure with good fitting models having low residual based
fit indices with values of 0.08 or less desirable and the value less than 0.1 is under acceptable
limit (Hu & Bentler, 1999; Schermelleh-Engel et al., 2003). Incremental fit indices or
comparative fit indices assess how well the model fits relative to an alternative baseline model or
the null model (with no measurement error). The various incremental fir indices include the
Normed Fit Index (NFI), Comparative fit index (CFI) or the Tucker-Lewis Index (TLI), with
suggestions for a cut off of 0.90 or 0.95 for a good fitting model (Hu & Bentler, 1999).
The Parsimony Goodness of Fit Index (PGFI) is adjustment to the GFI and NFI index that take
into account the parsimony of the model with acceptable cut off limits above 0.5 (Muliak et al.,
1989). Results of the structural equation modeling for main effects are shown in table 8.22.
Table 8.22 SEM model fit summary
DF CMIN CMIN/DF NFI IFI TLI CFI RMSEA
12 17.901 1.492 0.957 0.985 0.863 0.982 0.085
The fit indices indicate excellent fit for the model, with a Chi-square to degrees of
freedom ratio of 1.492 which is very less than that of the suggested cut off limit of 3 (Bollen,
1989; Gallagher, Ting & Palmer, 2008; Schermelleh-Engel et al., 2003). As this statistic is very
sensitive to sample sizes (Bollen, 1989), other fit indices have to be examined. Root mean square
error approximation is also lesser than 0.1 (RMSEA = 0.085). The incremental fit indices, NFI,
CFI are above cut off level (Hair, Anderson, Tatham and Black, 2006). The value of TLI is close
to 0.9. Thus, based on chi-square statistics and incremental fit indices, it can be concluded that
the model has a good fit. Multiple R square for the model was 0.657. The path coefficients or
standardized regression weights for the predictor relationships are shown in table 8.26.
As can be seen SEM results indicate that only centralization, learning culture,
employee training and emotional intelligence appear significant (p<0.05) in predicting
knowledge sharing. SEM results also shown that knowledge sharing has an significant positive
impact on team performance with p<0.05 again. The direction of influence is consistent with
earlier analysis in that increase in centralization would result in less knowledge sharing with
negative beta value i.e. -0.274 while increase in learning culture, employee training and
emotional intelligence would result in more knowledge sharing among the members of cross
functional teams with positive beta values i.e. 0.347, 0.344 and 0.261 respectively.

8.7 Controlling for demographic variables
A control variable is any factor that remains unchanged for the study and strongly
influences relationship between independent and dependent variables in the relationship. It is
held constant to test the relative impact of an independent variable. Additionally, separate
analysis was carried out for the data controlling for the demographic variables of age, gender and
job level. This was done by creating separate data sets for the varying levels of each of the
demographic variables. The results have been shown in the table 8.24. Result shows that there is
a significant difference in the results generated for male and female respondents. Similarly,
differences have been reported for respondents for different age group and job level.
