5. DATA ANALYSIS & DISCUSSIONS
5.1 QUESTIONNAIRE PART I (Q1- Q6) GENERAL QUESTIONS MEETING OBJECTIVE 1 &
6 FOR ALL RESPONDENTS OF THE SAMPLE POPULATION
To arrive at the objective 1 and 6, comprehensive in-depth literature review was made in
Chapter 2 for the period more than twenty years (1990-2013). Questionnaire Part I (Q1
to Q6) remains almost the same for ERP Customers, Vendors & Consultants. Q1
contains the full address of the company and Q2 about the level of designation in the
company. For the survey, ERP Customers (29%: Top level management, 57%: Middle
level management and 14%: Junior level management), ERP Vendor (45%: Top level
management, 37%: Middle level management and 12%: Junior level management), ERP
Consultants (55%: Top level management, 28%: Middle level management and 17%:
Junior level management) comprise the sample of population available for answering the
questionnaire details.
The 3Q is related with the brand of the ERP software being used in the company in which
SAP tops the chart with 34%, Oracle: 29% and others (like PeopleSoft, Microsoft
Dynamics, Ramco, Baan, Invensys, JD Edwards,WebERP4 World, Epicor, Sage, Navision
etc.) contains 37% of the primary data.

87
While the graph 2 shows the overall market share distribution for the time period from
February 2005 to May 2012. The collected data conclusively shows that SAP ranks
highest of the three vendors, with more than one-fifth (22-percent) of total market share.
It is followed by Oracle with 15-percent of total market share and Microsoft with 10-
percent of total market share. Tier II solutions (including Infor and Epicor) represent just
16-percent of the market while Tier III and others represent a commanding 37% of the
market.

Q5 deals with the business area/product of the company in which 73% comprises utility
area, 11% manufacturing and rest 16% comprises other areas as depicted in graph 3.

However, the best thing has come out in favour of ERP implementation in SMEs in terms
of objectives achieved as mentioned in Q6. All respondents are unanimously agreed that
more than 80% implementation objectives were achieved in terms of streamlining
business process, improving productivity etc.
5.2 QUESTIONNAIRE PART I Q7 (FOR ERP CUSTOMERS) & Q4 (FOR ERP VENDORS &
CONSULTANTS) “WHAT ORGANIZATIONAL PARAMETERS INFLUENCED THE
SELECTION OF ERP IMPLEMENTATION STRATEGY FOR SMES?”[MEETING
OBJECTIVE 3]
ERP applications are still an expensive affair, lots of doubts about their success
considering the failure-rate statistics floating on the Internet. After comparing the
combined values of each variable (on Likert Scale 1 to 5) for ERP implementation
strategy; the most important variable emerged from Frequencies Statistics table is “Level
of Commitment from Top Management” (3.95%) closely followed by “Information
Integrity” & “Resource Planning” (3.94%) with “Availability of the Resources” (3.88%)
as essential qualifier with companies with meager money and resources. One is not just
buying software; one is also buying into a vendor and their company culture therefore full
commitment from top management is the most vital factor in the analysis. It is a given for
information integrity that acceptable system’s results cannot be achieved when systems
are driven by inaccurate data and untimely, uncontrolled documentation. One of the
major challenges in industry today is the “Resource Planning” i.e. timely right sizing of
operations. Profit margins can be eroded by not taking timely downsizing actions, and
market windows can be missed and customers lost by not upsizing the direct labour force
in a timely manner. Only after acquiring all the above factors in hand, the organization is
able to think “Customer Satisfaction”(3.8%), “Change Management Technology”
(3.73%), “Cycle Time Management” (3.62%), “Size of the Organization”(3.60%),
“Need to Restandardize the Process” (3.58%), “BPR & Software Configuration” (3.53%)
factors. Lastly, “Performance Management” (3.46%) comes after everything else as
measurement systems can be motivational or de-motivational.

5.3 QUESTIONNAIRE PART I Q8 OF ERP CUSTOMERS, “WHAT WERE THE MOST
COMMON PROBLEMS ENCOUNTERED BY SMES DURING ERP IMPLEMENTATION?”
[FACTOR ANALYSIS & RELIABILITY ANALYSIS] MEETING OBJECTIVES 3 & 4
The central aim of this exploratory factor analysis (EFA) is to evaluate and prioritize the
most critical problems (MCPs) during ERP implementation. In effect, SMEs can take
care of these problems on war footing basis to realize its sustainable success stories with
most critical success factors (MCSFs). Data analysis is the process of ordering and
organizing raw data so that it can provide useful information. For the group of 104 ERPs
users, the data were first perused to check whether the data could be analyzed using
factor analysis on not. The KMO measures the sampling adequacy which should be
greater than 0.5 for a satisfactory factor analysis to proceed. Looking at the table 4 below,
the KMO measure is .627 and the Bartlett's test of sphericity is significant. Taken
together, these tests provide a minimum standard which should be passed before a
principal components analysis (or a factor analysis) should be conducted.

Communalities are the proportion of each variable's variance that can be explained by the
principal components (e.g., the underlying latent continua). Also known as h2, it can be
also defined as the sum of squared factor loadings. By definition, the initial value of the
communality in a principal components analysis is 1. In table 5 of common factor space,
MCPs with high values are well represented, while MCPs with low values are not well
represented. In this example, we don't have any particularly low values. They are the
reproduced variances from the number of components that we have saved.

In Table 6, Total Variance Explained (TVE) is the third criterion in solving the number of
factors problem. Factor loading shows straightforward correlation between the factors
and all the MCPs. It involves retaining a component if it accounts for a specified
proportion (or percentage) of variance in the data set. Eigen values are represented in the
total column of the table. Eigen value MCPs (TVE) with greater than 1 value can be
incorporated in final solutions. MCPs with highest Eigen value will be the most important
factor and so on. Each succeeding component will account for less and less variance. %
of Variance column contains the percentage of each principal component variance. The
cumulative% column contains the cumulative percentage of variance accounted by the
current and all preceding principal components. For example, the last row shows a value
of 79.378. This means that the first five components together account for 79.378% of the
total variance.

Table 7. Rotated Component Matrixa of Customer’s MCPs (Source: SPSS V 18.0) [Source: Self Made]
In Table 7 for Rotated Component Matrix, all 15 factors have reduced into five
constructs. The first component is the most highly correlated with maximum
component’s value. After going through each row, we concentrated on the components
that each variable loaded most strongly on. Based on the factor loadings, the first Factor
or the most critical problem Construct 1 comprises of MCP 7, MCP 6, MCP 1, MCP 8
can be termed “Project Process related Problems” as Inaccurate Data and Unkempt
Knowledge Base leads to High Cost of ERP for SMEs. Further Lack of Tailoring of ERP
Software adding miseries to the woes. Since accurate data and knowledge base is the
lifeline of proper ERP implementation; the joint efforts of consultants, vendors and
customers can automate core activities of the organization by re-engineering vital
business activities or by making adjustment in the software (tailoring) according to
organizations requirement (Holland & Light, 2001)[47]. Taking full advantages from
ERP implementation requires Business Process Reengineering (BPR) and it is achieved
through an exhaustive analysis of current business processes. It helps to identify potential
changes in the business processes to avoid customization of the software (Al-Mashari et
al., 2002) [74].
While MCP 2, MCP 15 and MCP 12, all loaded strongly on Construct 2 “Project
Management related Problems” which can be defined as “Inability to accurately Map
Business Process & IT, Inadequate Training & Documentation and Lack of Will to Join
World Class ERP Implementation with Lean Six Sigma become instrumental in
escalating cost, complexity and failure risk of ERP implementation.” These factors badly
need lean approach for immediate gain and six sigma concepts for continuous evaluation,
control and improvement. In the implementation phase, training and education become
other important factors. The implementing organizations must think about proper training
and education from the vendors/consultants before deciding to implement a particular
93
ERP solution (Al-Mashari et al., 2002)[74]. Sia (2002) argued that the SMEs are evident
to fail to achieve the benefits from the ERP project because of the lack of staff with
appropriate education and training on technology related to the ERP systems [98]. Hence
it is an important that the implementing organization evaluates whether the vendors or
Suppliers of ERP solutions provide enough training and education. Johansson and
Sudzina (2009) also identified that it is an important selection criteria of Open Source
ERP Selection. Further, better knowledge about Lean ERP is suitable strategic method
for achieving SME’s objectives [54].
Later MCP 4, MCP 14 and MCP 3 loaded strongly on Construct 3 “Project
Implementation related Problems” as Poor IT Infrastructure, High Turnover Rate of
Project Team Members and Lack of Proper Management System. These issues occur all
the time, typically due to poor planning or a lack of proper execution of the project.
Simply buying an ERP system is not a quick fix for a business. Implementing a system
requires a concerted effort across an organization. If companies are unable to administer
proper implementation techniques, it may be best to contact a managed services provider
that can assist with ERP operations and allow business to profit from their investment.
By optimizing project management for better ERP implementation, too much software
modifications or tailoring can also be prevented.
The Construct 4 contains MCP 11, MCP 13 and MCP 5 can be summarized as “Change
Management related problems” tells that “Lack of Proper Monitoring, Improper Gap
Analysis and ERP Software Misfits lead to Cost Overruns”. While ERP systems, in
theory, are acquired to assist in efficient, cost-saving strategies; improper functioning
without change management could end up costing more money in continuous
maintenance and convoluted operations. Without using best practices with the changing
environment, involving the procurement and implementation of a solution, an ERP
system could in fact make matters worse.
Further, the MCP 10 and MCP 9 define Construct 5 as “Hidden Hurdles for SMEs”.
It reflects in “Elongated Implementation Time and Inability to Calculate Hidden costs”.
In addition to the cost of purchase, most organizations often fail to factor in hidden costs
during evaluation, consulting, implementation, training, transition, delayed ROI and post
implementation support. All the above factors can lead to cost overruns, schedule
94
overruns and functionality overruns. This ultimately results in negative ROI and a
prolonged payback period. Elongated implementation time often leads to fatigue, stressed
and dubious state of mind in customers which affect the growth period of ERP, to a
greater extent.
After examining factor scores for all the five constructs, reliability test was conducted
separately. Reliability analysis is determined by obtaining the proportion of systematic
variation in a scale, which can be done by determining the association between the scores
obtained from different administrations of the scale. Thus, if the association in reliability
analysis is high, the scale yields consistent results and is therefore reliable. Cronbach's
alpha is a measure of internal consistency (reliability), i.e.; how closely related a set of
items are as a group. A "high" value of Cronbach alpha as depicted in table 8 (Construct
1 scored .832), table 9 (Construct 2 scored .839) as quite good suggesting that the items
have relatively high internal consistency, table 10 (Construct 3 scored .730) and table 11
(Construct 4 scored .712) as OK. Table 11 constructs having low value of alpha could be
poor interrelatedness between items that can be further revised or discarded.

In conclusion, the results are completely a root cause analysis for SMEs where actual
results are below goals or when goal are significantly below external benchmarks. SMEs
10 years back could manage without ERP, but no more! Optimized Project Management
and Change Management are about setting expectations that lessen the pain of change. If
Indian SMEs can adapt the ERP software with only essential customization/tailoring, not
only can it benefit by the global practices incorporated in the system, but also save huge
money and time. Thus cost of an ERP depends on the management’s willingness to go
with the ERP or the extent of tailoring it needs. Besides ERP can be the road to
prosperity if one can implement world class ERP to product and process improvement/
benchmarking through the effective use of statistical methods in Lean Six Sigma skills. In
view of the above result and discussions, with all its pros & cons clubbed together, the
journey to MCPs to MCSFs is safe and feasible reality for SMEs towards a sustainable
growth of ERP.

Further Item analysis/ Reliability analysis helps in evaluating the correlation of related
survey items with only a few statistics. Most important is Cronbach's alpha, a single
number that tells that how well a set of items measures a single characteristic. This
statistic is an overall item correlation where the values range between 0 and 1. Values
above 0.7 are often considered to be acceptable. In the same way, a group of 4 questions
Q5b, Q5m, Q5p and Q5g can be summarized in “Project management related problems
with ERP & lean six sigma” with Cronbach’s Alpha value .850 (Good) as the foremost
and most important factor. Second construct/characteristics can be defined as “Project
process related problems” having Cronbach’s Alpha value .808 (Good). The third
construct ”Project implementation related problems” having α value .697 (nearly Good)
and the fourth construct “Change management related factors” construct with α value
98
.613 and the fifth one “Hidden hurdles for SMEs” (α value .528) suggest that respondents
gave markedly different ratings which can be adjusted further.
5.5 QUESTIONNAIRE PART I Q5 OF ERP CONSULTANTS “WHAT ARE THE MOST
COMMON PROBLEMS VIEWED BY CONSULTANTS DURING ERP IMPLEMENTATION?”
[FREQUENCY ANALYSIS ON LIKERT SCALE 1 TO 5] MEETING OBJECTIVES 3 & 4
To know how to get the best from an ERP package, it is important to first analyze the key
factors that are responsible for ERP failures. According to ERP Consultants, lack of
proper monitoring system (on the whole) is the leading problem (4.33%), leaving project
management (as a part of whole system) far behind (3.73%). It needs top management
intervention at the priority basis. Elongated implementation time coupled with
inadequate training and documentation (4.2%) sequenced by combined effect of high cost
of ERP system with lack of tailoring of ERP software (4.13%) are the next major
headache related with project management related problems.
Graph 6: MCPs Encountered by SMEs Consultants (Source: SPSS V 18.0 & MS-Excel 2007) [Source: Self Made]
Next frequent problems come under the purview of change management & software
engineering related areas. These are improper gap analysis (4.10), inability to accurately
map business process & IT (3.90), high turnover rate of project team members (3.8), poor
IT infrastructure (3.77%), a mixed effect of inaccurate data, unkempt knowledge base
(3.73%), lack of will to join world class ERP implementation with lean six sigma
99
(3.63%) and ERP software misfit. Obviously, inability to calculate hidden cost (3.37%)
comes in last but this ultimately results in negative ROI and a prolonged payback period.
5.6 QUESTIONNAIRE PART I Q9 OF ERP CUSTOMERS, “WHAT THE END CUSTOMER OF
SMES IS LOOKING FROM THE ERP SOFTWARE?” [FACTOR ANALYSIS][MEETING
OBJECTIVE 3]
The topic of the questionnaire is very relevant and the terms coined as end customer
factors (ECF1 to ECF8) to denote the concepts used here. For the group of 104 ERP
customers, the KMO measure of sampling adequacy in table 16 is .619 and the Bartlett's
test of sphericity is .000 (less than 0.05) is noteworthy to conduct factor analysis. As
shown in table 17, TVE table and Scree plot for the data show collective percentage
accounted by the first four major components around 67.451 of the total variance.

In conclusion, the most important characteristics that have emerged in the scenario can be
contrived as “Lean ERP”, which the end customer is looking for. “Vendor customer
relationship for fast turnaround” comes at the next position, thirdly “User benefit” and
lastly “User friendliness”.

By using rotation method (Varimax with Kaiser Normalization), 8 factors have reduced
into three constructs only in comparison of four for ERP customers (as mentioned in table
21). From the Vendor point of view, the most important requirement for the user is again
“Lean ERP” with one feature extra as high quality of product that the user craves for. At
the second place, “User friendliness” and lastly, “User benefit” in terms of vendor
customer relationship. It is really surprising to note here that low unit cost does not carry
much importance in comparison of high quality of product.

1 TO 5] [MEETING OBJECTIVE 3]
From the survey, it is clear that “High quality of product” (4.43%) with “Ease of
customization” (4.3%) & “Fast turnaround” (4.23%) commands the topmost position for
the Consultants just as Customer’s requirement list. SMEs require flexibility of the ERP
system (tailoring / optimizing parameters) because of their individual operational process.
“Data conversion and integrity” (4.20%) is the next important prerequisite, sequenced by
“Vendor-Customer relationship” & “Focused Performance Measure” (having same rating
of 4.10%). Unexpectedly, “Low unit cost” (3.63%) matters least for them followed by
“User friendliness” (4.0%) as they emphasis most on best quality of product.

5.9 QUESTIONNAIRE PART I Q10 FOR ERP CUSTOMERS, Q7 FOR ERP VENDORS &
CONSULTANTS, “HOW SMES MAKE DECISION FOR SELECTING AN ERP VENDOR?”
[COMPARATIVE FREQUENCY ANALYSIS WITH SUMMATED SCORES FOR ALL
RESPONDENTS] [MEETING OBJECTIVE 3]
ERP Vendor Selection process can be a very complicated and problematic for SMEs if
they don't know how to approach it from the very start. Different clients have different
needs ranging from functional requirements, technical maturity, tolerance for risk,
budget, and a host of other factors. These variables influence not only the choice of
vendor, but also the choice of specific solution offered by the vendors. Since the number
103
of decision factors (DF1to DF7) is less for the criterion set for ERP Customers, Vendors
and Consultants, we opt for combined frequency analysis in which the maximum
summated score gained by the factor “Vendor Credentials” (4.29%). Reputation of the
vendor is the most important factor for selecting the vendor and is fully supported by the
primary and secondary data of the Survey. SAP tops the chart with 34%, Oracle: 29%
and others (like PeopleSoft, Microsoft Dynamics, Ramco, Baan, Invensys, JD
Edwards,WebERP4 World, Epicor, Sage, Navision etc.) contains 37% of the primary
data. The secondary report shows that majority of companies (77 percent) adopted Tier I
ERP software in which people refer SAP: 35 percent, Oracle: 28 percent, Microsoft: 14
percent and Tier II: 23 percent. “Flexibility / Well Managed User Interface” (4.21%) is
the second major factor, sequenced by “Total Cost of the ERP system” (4.11%), “ERP
Functionality” (4.9%) and other factors also have more than 4 value. “Maintenance
(3.75%) reaches to the last of ladder (in between Agree and Neutral of Likert scale) as it
is self managed by the IT staff of the company.

VENDORS & CONSULTANTS “WHAT IS THE BEST WAY OF ERP SOFTWARE
TAILORING/ ADAPTING?” [COMPARATIVE FREQUENCY ANALYSIS WITH
SUMMATED SCORES OF ALL RESPONDENTS] [MEETING OBJECTIVE 5]
The next important modification in implementation phase can be made by optimization /
tailoring of parameters (called configuration), rather than by traditional programming. In
all options, “Data fit of ERP” and “User Fit of ERP” (4.34%) get the maximum
representation of the data from the combined samples of all respondents. The next factor
“Process Fit of ERP” with 4.31% scores gives a tough competition to both the factors.
“Organization Fit of the ERP” (4.00%) is also a strong variable especially in SMEs in
which scarcity of the five M's”: men, machines, methods, materials and money is the
precious word to deal with. “Consultant fit of ERP” is the last option with 2.84% score on
Likert scale in between Neutral and Disagree. The representation found in survey result
may be useful for helping practitioners assess risk and plan appropriate risk mitigation
efforts. The basis for the analysis can be the whole project or a specific area of the
project, e.g. production planning and control in one line of business. The ERP package
tailoring typology can also be used to predict success both during the initial
implementation phase and during the maintenance and post implementation phase of the
ERP system life cycle.

Factor loading shows the simple correlation between the factors and all the variables
which can be further used to fix on which variable belongs to which factors. The PCs are
ordered and assigned a number label, by decreasing order of contribution to total
variance. The PC with the highest loading or with the largest fraction contribution is
labeled with new label name for the emerged factors.
Rotated factor matrix is the best solution for this. In table 24, each variable belongs to
the factors with which it has the highest loading. From this process, we are able to find
out all the constituent variables of each factor. It is seen from the TVE table that only 3
factors have Eigen value over 1. Cumulative variance of 64.159 % also proves that a
good factor analysis has been done. The factor analysis performed on 20 items resulted
into the extraction of 3 components.

The Rotated Component Matrix in table 24 above shows the factor loadings for each
variable. On the basis of the content, feature, characteristics of each component, suitably
names are assigned to each factor. In this way, factor analysis is used here to identify the
basic constructs that influence the latest trends of ERP implementation at Indian SMEs.
108
After going through each row, we concentrated on the components that each variable
loaded most strongly on. Based on the factor loadings, the first construct or the most
important factor Factor 1 comprises of F1 F5 F6 F7 F8 F11 F12 F15 F14 F19 can be
renamed as “Aligning Lean Six Sigma to ERP brings better results for SMEs”. While F4
F13 F16 F17 F18 all loaded strongly on Factor 2 which can be defined as “Education of
the top management is instrumental in optimizing project management & change
management process for better ERP implementation”. In effect of this, too much software
modifications or tailoring can be prevented that results in reduced cost, complexity and
failure risk of ERP implementation for SMEs. Later F2 F3 F9 F10 F20 loaded strongly
on Factor 3. The Factor 3 can be summarized as “For all level of management, better
knowledge about Lean ERP is suitable strategic method for achieving SME’s objectives”.
Though lean approach to six sigma always driven by senior management, every level of
management is responsible for its success. These are concentration-intensive tasks
applicable on all level. Lack of knowledge transfer at any stage of Indian ERP
implementation leads to dissatisfaction and bad performance.

1 scored .917 as excellent, Construct 2 scored .872 and Construct 3 scored .841 also as
very good. Therefore high association in reliability analysis shows the consistent and
reliable result, fulfilling all the objectives defined in the paper.
109
In view of the above analysis and discussions, subsequent to the exploratory study of
current ERP implementation status in India, we can conclude that optimizing software
engineering, project management and lean six sigma techniques lead to successful and
pragmatic implementation of ERP in SMEs as represented beneath in theoretical model in
figure 8.

Since ERP's software development life cycle (SDLC) explicates the process of lean six
sigma implementation, it must modify ERP system functionality with customer
requirements and change management that will allow SMEs to get the benefits of its use
and will also help in getting the right results, in the right timeframe, at the right cost as
mentioned in figure 9 below.

110
Before ERP implementation, SMEs can use the benchmark analysis of other companies
to maximize the benefits. Control independent Lean expertise needed to help ERP team
in selecting right software, implement effectively and manage organizational changes at
all level. At the same time, Six Sigma improves the way for overall quality of products in
measurable terms [151]. If companies considerably concentrate on these points, they will
survive, thrive profitably in the future ERP market.
