Implementing labor flexibility: A missing link between acquired labor flexibility and plant performance

Abstract

a b s t r a c tThe existing studies conceptualize a direct relationship between acquired labor flexibility and plant performance, producing inconsistent empirical results, which makes the topic ripe for further inquiry. We believe acquiring labor flexibility is not sufficient; its implementation is an important intervening step when companies have to tackle accompanying technical and behavioral side effects of labor flexibility. In this paper, we develop and test a theoretical model in which we introduce an intervening variable to capture the implementation of labor flexibility. In addition, evolving human resource management practices that promote acquisition of labor flexibility are also examined in our model. Case studies in ten printed circuit board plants validated our model. Subsequently, survey data collected from 74 PCB plants was analyzed using Partial Least Squares method. Supporting the proposed model, the results show that the impact of acquired labor flexibility on plant performance is not direct but experienced through the sophistication of labor flexibility implementation exercised by the plant. Our findings also suggested that plants that emphasized process-focused training, provided greater job-rotation training, and designed positive reward structures, acquired higher labor flexibility.

Leveraging fitness and lean bundles to build the cumulative performance sand cone model

“…Quality and cost performance were each measured using a single item, using the same items as Bozarth et al (2009). Singleitem perceptual measures are acceptable when the object of the construct is concrete, uniformly imagined (Bozarth et al, 2009) and when it is sufficiently narrow and unambiguous to the respondent (Wanous et al, 1997); thus, a number of studies using single-item perceptual measures can be found in the operations management literature (Koufteros et al, 1998;Sawhney and Piper, 2002;Bergkvist and Rossiter, 2007;Bozarth et al, 2009;Gimenez et al, 2012;Sawhney, 2013). Delivery and flexibility performance were each measured as two-item measures, using the measures validated by Liu et al (2009) andLee (2009).…”

The knowledge transfer process in Six Sigma subsidiary firms

“…Although our sample size is not large enough to use these approaches, PLS is especially suitable for studies with small sample size (Benitez-Amado and Walczuch, 2012;Chin et al, 2003) and consequently more appropriate for our study. Operations management journals have recently incorporated this approach in their publications (Lockstrom and Lei, 2013;Mackelprang, Jayaram and Xu, 2012;Perols, Zimmermann and Kortmann, 2013;Sawhney, 2013). Mackelprang et al (2012) give a detailed explanation of PLS usage in cases of operations management publications.…”

The extent of EFQM effectiveness in routine and non-routine organizations based on multivariate techniques: an empirical study

“…Thus, one of the differences between organizations with more non-routine activities and processes and routine organizations is the high level of human resource flexibility (Schafermeyer et al 2010;Lillrank 2003;Lillrank et al 2011;Romero et al 2015). Several studies have been conducted to measure the level of human resource flexibility and its effects on the performance of organizations (Ketkar and Sett 2009;Vela-Jiménez et al 2014;Sawhney 2013;Beltrán-Martín et al 2008) and in those studies two factors, including skill flexibility and behavior flexibility have been mainly introduced by them for internal human resource flexibility (Ketkar and Sett 2009;Beltrán-Martín et al 2008;Bhattacharya et al 2005;Wright and Snell 1998;Beltrán-Martín and Roca-Puig 2013;Way et al 2012;Ketkar and Sett 2010).…”

“…Skill flexibility (SF) refers to the extent employees can easily and quickly comprehends new skills and abilities (Beltrán-Martín et al 2008) and its main attributes are: team based working (Ketkar and Sett 2009;Bhattacharya et al 2005), employee's learning abilities (Ketkar and Sett 2009;Beltrán-Martín et al 2008;Bhattacharya et al 2005), possessing multiple skills (Ketkar and Sett 2009;Sawhney 2013;Bhattacharya et al 2005; Beltrán-Martín and Roca-Puig 2013), and capability of putting new skills to use within a short time (Sawhney 2013;Bhattacharya et al 2005).…”
