The inference drawn from the above tables and charts for the 3 Role Shift

Factors are detailed below.

207

Inference from the Tables and Charts

Open Source ERP Emerging Trend

1. Horizontal Role Shift Perception: An overwhelming majority of the

Oracle Functional Consultants - over 75% and SAP Functional Consultants - over

77%, have given 'First Rank' to post-trend 'Horizontal Role Shift'.

It only means that most of the Consultants in both the ERPs feel that due to

the impact of the ‘Open Source ERP Emerging Trend’, their career will undergo

primarily a 'Horizontal Role Shift'.

2. Vertical Role Shift Perception: Both the Oracle and SAP Functional

Consultants seem to agree that 'Vertical Role Shift' due to the ‘Open Source ERP

Emerging Trend’ will only have a tertiary impact on their career.

This can be inferred from the 'Third Rank' given to the post-trend 'Vertical

Role Shift' by over 69% of the Oracle Consultants and 78% SAP Consultants.

3. Technical Role Shift Perception: There is a high degree of

convergence of the perception of the post-trend 'Technical Role Shift' due to the

onset of ‘Open Source ERP Emerging Trend’, which they feel will have only a

secondary effect on their career.

Majority of Oracle Functional Consultants of 59% and over 64% of the

SAP functional Consultants have given a second rank to the post-trend 'Technical

Role Shift'.

Interpretation of the Statistical Test

The Null Hypotheses H0 formulated for 'Open Source Emerging Trend' is

tested using Mann-Whitney U Test, based on a probability of 95% confidence

interval (i.e.,) a significance level of 0.05. The result table of the comparison of

the two ERP groups, shows the test statistic U value as well as the asymptotic

significance (2-tailed) P-value.

The P-values of all three post-trend Role changes 'Horizontal Role Shift

(0.784)', 'Vertical Role Shift (0.053)' and 'Technical Role Shift (0.053)' are higher

than the significance value 0.05. Hence all the three Null Hypotheses stating that

there are no significant differences between the groups of Oracle and SAP

Consultants are accepted. It is also evident from the uniform ranking given by the

Consultants on the effect of the Trend on their career as seen below.

Horizontal Role Shift Vertical Role Shift Technical Role Shift

The inference drawn from the above tables and charts for the 3 Role Shift

Factors are detailed below.

214


SME Sector ERP Emerging Trend

1. Horizontal Role Shift Perception: Majority of the Oracle Functional

Consultants, over 75% of them feel that due to the impact of the ‘SME Sector

ERP Emerging Trend’ their career will have a post-trend 'Horizontal Role Shift'

as evident from the 'First Rank' rating.

Whereas, over 65% of the SAP Functional Consultants differ and feel it

will only have a secondary impact on their career as seen in the 'Second Rank'

given to the post-trend 'Horizontal Role Shift’.

2. Vertical Role Shift Perception: Again there seems to be a perceptional

difference between the Oracle and SAP Consultants on the issue of SME Sector

ERP induced 'Vertical Role Shift'.

The Oracle Consultants feel there will be very little of the 'Vertical Role

Shift' as they have given only 'Third Rank'. But the SAP Consultants markedly

disagree, as over 80% of them brace themselves for the 'First Rank' post-trend

'Vertical Role Shift' due to the ‘SME Sector ERP Emerging Trend’.

3. Technical Role Shift Perception: The divergence in views seems to

naturally persist between the two ERP Consultants when it comes to 'Technical

Role Shift' as a result of the ‘SME Sector ERP Emerging Trend’.

While over 56% of Oracle Consultants give the post-trend ‘Technical Role

Shift’ a 'Second Rank', over 73% the SAP Functional Consultants give it a distant

'Third Rank'. It only means that both the ERP Consultants are not much exercised

by the possibility of the post-trend 'Technical Role Shift'.

The Null Hypotheses H0 formulated for 'SME Sector Emerging Trend' is





The P-values of all three post-trend Role changes - 'Horizontal Role Shift,

'Vertical Role Shift' and 'Technical Role Shift' - are lesser than the significance

value 0.05. Hence all the three Null Hypotheses are rejected and the alternate

Hypotheses confirming the existence of significant difference between the two

groups of ERP Consultants are accepted. It is also seen from the varied ranking

given by the Consultants on the post-trend role shift as shown below.

BI Analytics in core ERP Emerging Trend

1. Horizontal Role Shift Perception: Majority of the both the Oracle

Functional Consultants - over 71% and SAP Functional Consultants - over 67%,

have concurred on the same ranking - 'Third Rank' to post-trend 'Horizontal Role

Shift'.

It only means that most of the Consultants in both the ERPs are not much

perturbed as they see post-trend Horizontal role change only as a distant

possibility due to the impact of ‘BI Analytics Emerging Trend’.

2. Vertical Role Shift Perception: Both the Oracle and SAP Functional

Consultants seem to agree that 'Vertical Role Shift' due to the ‘BI Analytics

Emerging Trend’, will only have secondary impact on their career.

This can be deduced from the 'Second Rank' given to the post-trend

'Vertical Role Shift' by over 59% of the Oracle Consultants and SAP Functional

Consultants.

3. Technical Role Shift Perception: ‘BI Analytics Emerging Trend’

seems to be very highly impacting the technical role in the careers of both the

ERP Consultants.

This result is evident from the 'First Rank' given to the post-trend

'Technical Role Shift' by over 75% of the Oracle Functional Consultants and over

79% of the SAP Functional Consultants.
