Item generation

To achieve the content validity for IT resoimces, previous literature was reviewed (e.g., Ross et al. 1996 Weill et al. 1996 Armstrong and Sambamurthy 1999 Bharadwaj 2000 Byrd and Turner 2000 Dehning and Richardson 2002 Melville et al. 2004 Peppard and Ward 2004 Ranganathan et al. 2004 Bhatt and Grover 2005 Piccoli and Ives 2005 Ravichandran and Lertwongsatien 2005 Ray et al. 2005). Based on the definitions presented in Table 3.1, 14 items were developed to measure IT resoimces as the bundles of FT assets and capabilities that can be used to support lOS use in supply chain collaboration. These initial items were developed with two scales in mind. 

Items for lOS appropriation were developed based on a rigorous review of available literature (e.g., Bensaou and Venkatraman 1995 Mehra and Nissen 1998 Milton et al. 1999 Bafoutsou and Mentzas 2002 Christiaanse and Venkatraman 2002 Grover et al. 2002 Mukhopadhyay and Kekre 2002 Salisbury et al. 2002 Barua et al. 2004 Manthou et al. 2004 Subramani 2004 Chi and Holsapple 2005 MaUiotra et al. 2005 Saeed et al. 2005 Nissen and Sengupta 2006). Based on the definitions provided in Table 3.2,15 items were developed to represent the extent of lOS use. Items were expected to measure three groups corresponding to the three subdimensions proposed in the previous chapters. 

In summary, there are a total of 23 constructs and 117 items shown in Table 6.1.

The FAQLQ-PF and -TF were developed and validated in four stages (1) item generation using focus groups with both children and parents, expert opinion, and literature review (2) item reduction, using clinical impact and factor analysis (3) internal and test-retest reliability and construct validity were evaluated and (4) cross-cultural and content validity was examined by administering the questionnaire in a US sample (FAQLQ-PF, only). 

Test construction and item generation under schema theory require new approaches. It is worth considering how test items can be constructed to reflect the linkages expected in students knowledge of a subject. The nature of the linkages points to two possible representations a hierarchy and a network.

As seen from the table and figure, 80% of the sales volume is captured by slightly less than 20% of the items, and in total, "A" and "B" items represent 45% of the total item count and capture approximately 95% of the sales volume. The top 10 items from CBA s ABC analysis are shown in Table 3.2. Interestingly, the top two items demonstrate a marked contrast, with the top item generating almost 800,000 in sales from only 3,500 units of annual sales volume and the second item generating more than 700,000 in annual sales from almost 169,000 units in volume.
