POPULATION, SAMPLING AND SAMPLING SIZE<br />
The focus <strong>of</strong> the selection <strong>of</strong> sample size have large<br />
representation <strong>of</strong> pr<strong>of</strong>essionals and practicing managers<br />
from this industry and covered working executives out <strong>of</strong><br />
supply management in order to solicit a different perspective<br />
on the questions raised on supply process and management.<br />
The structurally disorganized focus group was to help in<br />
arriving at judicious evaluations with liberal input SCM<br />
models from various countries.<br />
The population was selected under convenient<br />
sampling design among the members <strong>of</strong> Indian Institute <strong>of</strong><br />
Materials Management (IIMM) at Tamilnadu level and<br />
among the Alumni <strong>of</strong> IIM Calcutta <strong>of</strong> a particular year,<br />
2006-07. The population from IIMM represented different<br />
industries which had similar characteristics and constraints<br />
(Sandberg, 2007) in supply chain and the population from<br />
IIM-C had many similar logistics challenges in common<br />
from process point <strong>of</strong> view since they represented top<br />
management <strong>of</strong> various industries.<br />
DATA COLLECTION METHODS AND TOOLS<br />
Primary data was collected through a structured<br />
questionnaire. An online questionnaire using Google forms,<br />
accompanied by a covering letter designed was sent to the<br />
sample lot selected.<br />
- The questionnaire had four parts viz., a)<br />
Demographic section, b) SCM<br />
information, c) Supply Process and<br />
Management and d) Psychographic<br />
section.<br />
- Section (a), the demographic section had<br />
23 questions related to the back ground<br />
<strong>of</strong> the individual and industry pr<strong>of</strong>iling.<br />
- Section (b) or the SCM information<br />
section did largely deal with SCM<br />
information about the individual and the<br />
respondent’s organization. The numbers<br />
<strong>of</strong> questions were four with multiple<br />
selection choices.<br />
- Section (c)- The questionnaire was<br />
designed to have a mix <strong>of</strong> general SCM<br />
and specific to construction industry.<br />
Each factor had four statements with 5<br />
point likert scale ranging from ‘Strongly<br />
agree’ to ‘Strongly disagree’.<br />
The source <strong>of</strong> secondary data were research<br />
journals, white papers, books, popular journals, articles,<br />
research dissertations, institutional publications, newsletters<br />
and internet resources which are historical and cannot be<br />
altered.<br />
Questionnaire was sent via email and followed up<br />
with the target population through telephone. The gross<br />
response rate was 40.28% (257/638). Out <strong>of</strong> 257 received<br />
questionnaires, 17 were rejected because they were<br />
duplicated and incomplete in many respects. Therefore, the<br />
net response rate was 37.62% (240/638) which was<br />
considered a satisfactory response rate for the purpose <strong>of</strong><br />
this research. Forslund (2004) identified that the response<br />
rates ranged from 5% to 58% in research projects using<br />
questionnaire survey methods. However, 20% response rate<br />
was suggested by Forza (2002) for similar questionnaires.<br />
DATA ANALYSIS<br />
Analysis tool SPSS, version 13 was used to analyse<br />
the data collected. Analytical tools such as one way<br />
ANOVA (Analysis <strong>of</strong> Variances) and regression analysis,<br />
mean and standard deviation, multiple co-relation and<br />
frequency tests were used.<br />
ANALYSES AND DISCUSSIONS<br />
<strong>Table</strong>-1: Regression analysis for dependent variable -<br />
Disruptions with independent variables<br />
From the observed R Square value 0.352, it was<br />
inferred that the independent variables have 35.2%<br />
influences on SCM factor – disruptions. It was also<br />
confirmed by the obtained. 'f' value 5.361 which was<br />
significant at 0.01 level. Among the selected independent<br />
variables viz., gender, age, residence and work location<br />
types, educational qualifications, management position,<br />
SCM education, overall experience, SCM experience and<br />
SCM knowledge were found to influence the disruptions.<br />
There were many uncertain moments in a supply<br />
process. Supply chains and disruptions were synonymous in<br />
organizations risk management strategy. A fire accident few<br />
years ago in Hanil Lear, the only vendor then to supply car<br />
seats, near Chennai put Hyundai motors operations on hold<br />
for three good days. So was the recent case <strong>of</strong> Tata Motors<br />
short in production targets with Mico, the fuel injection<br />
pump vendor, caught under the clouds <strong>of</strong> recent Jaipur Oil<br />
inferno. Labour unrests in auto components hub <strong>of</strong> India-<br />
Gurgaon pushed many automobile manufacturers in<br />
hardship. Delays can result in loss <strong>of</strong> time and money as<br />
well as inconveniences to the public and they are caused<br />
externally or internally (Vidalis and Najafi, 2002). Some <strong>of</strong><br />
the causes for delays in construction industry were<br />
designers, owners, contractors, suppliers, governments,<br />
weather etc.<br />
Low cost sourcing and just in time were also risks<br />
which can cause disruptions stretching farther than they’ve<br />
ever stretched in the past and resultant fear is consequences<br />
<strong>of</strong> a more severe disruption – read risk, commented Rudd<br />
(2006). Supply chain disruptions might also reduce the<br />
shareholders value and opportunity costs in time sensitive<br />
products or market. In disaster induced disruptions, a<br />
carefully calculated risk management policy alleviates<br />
adverse impacts <strong>of</strong> such disruptions (Papadakis, 2002).<br />

SCM Factors<br />
Among the 24 dependent variables, owner/client, project<br />
management characteristics, price, production perspective,<br />
collaboration results, IT in SCM and sustainable SCM<br />
whose P values are 0.002, 0.007, 0.036, 0.003, 0.003, 0.006<br />
and 0.008 were only been found to have significant<br />
association (29.2%) with the dependent variable - type <strong>of</strong><br />
