The implementation of the four shop floor management tools
Table 6.17 depicts the participants’ shop floor management implementation experience. It constitutes the 5S practice (I5S), standard operations (SDO), waste removal (WSR) and visual management (VSI).

The participants reported a wide variation in 5S practice (I5S). From Table 6.17, the responses spanned from 1.4 (below “use very rarely”) to 7 (“always use”) on a 7-point Likert scale. Nevertheless, as presented in Figure 6.2, only 4.4% of the respondents rated it below the midpoint of 4 (“use occasionally”). Nevertheless, 52.6% of respondents rated it between 5 and 6 (“use frequently” and “use very frequently”) and a further 25.4% of respondents rated it between 6 and 7 (“use very frequently” and “always use”). Thus, the mean response was above 5 (“use frequently”) at 5.35, which implied a high frequency of use of 5S practice for the majority of respondents.

The participants generated a wide range of responses to the use of standard operations (SDO) question. Table 6.17 shows that the lowest figure was 2 (“use very rarely”) and the highest was above 6.75 (“use very frequently”) on a 7-point response scale. Nevertheless, the overall mean was above the midpoint of 4 (“use occasionally”) at 5.32. Figure 6.2 unearths that overall 42.9% of respondents rated it between 5 and 6 (“use frequently” and “use very frequently”) and a further 18.8% of respondents rated it 6 and above (between “use very frequently” and “always use”). Therefore, the figures obtained from the case companies showed a high frequency of use of standard operations.

The results depict a lower frequency of use of waste removal (WSR) and visual management (VSI). It is very clear from Table 6.17 that the overall means for waste removal (WSR) and visual management (VSI) were less than 5 (below “use frequently”) at 4.23 and 4.52 respectively. However, two-thirds of the respondents actually admitted that they have implemented these two tools more than occasionally. As shown in Figure 6.2, on the 7-point response scale, 63.9% (40.1%+15%+8.8%) of the total responses observed were above the midpoint of 4 (above “use occasionally”) for waste removal (WSR) and 74.9% (32.3% + 37.9% + 4.7%) for visual management (VSI). These results indicated that, for the participating organisations, most, although not all, of the shop floor respondents, had implemented waste removal and visual management more than occasionally.
