The revised scales to measure improvement implementation are depicted in Table 6.26. Based on the factor analysis results, these possess high construct validity which implies that the questions actually measure what they are designed to measure,( Hair et al., 2010; Stangor, 2011).

• Cont1: My improvement activities have a positive effect on the shop floor area

• Cont3: My improvement activities have improved the performance of this shop floor area
• KSk9: Overall, the improvement activities helped me and my colleagues work together to improve performance
Shop floor skills
(SFK) • KSk5: I can communicate new ideas as a result of participation in improvement activities
• KSk6: I gained new production skills as a result of participation in improvement activities

Table 6.26 The revised measures for improvement outcomes
This chapter elaborated the data collection and screening procedures. The data were collected from 10 Indo-Japanese automotive joint ventures. A questionnaire was derived from pretested and validated questions. It was distributed using the self-administered method. 1000 questionnaires were distributed of which 527 were returned. However, 25 (6.8%) contained missing values, so 502 were valid samples, giving a response rate of 50.0.2%. SPSS was used to assess the construct validity and summarise the patterns of the collected samples.
In the subsequent chapter, the theoretical model will be developed. Thereafter, structural equation modelling with path analysis will be used to analyse the data, shape the proposed theoretical model, and test the hypotheses.
