ERP Implementation Approach
The study collects data from 5 business units of the company. The data collection method is through both qualitative and quantitative data analysis, and the study collects data to enhance greater understanding of the ERP implementation approach carried out by the company. As being discussed previously, the methodology used to collect data is through qualitative and quantitative approach, and the study collects data from the following business units:
Accounting Department
Human Resources Department
Purchasing and Supply Department
Manufacturing and Product Development Department
IT (Information Technology) Department.
The study selects these business units because they are the most important business departments that focus on the core business activities of the company. The selected company represents a cross section of the major companies engaging in the ERP implementation. Typically, the information collected from the company is treated with high confidentiality, and the company chooses to implement ERP system to facilitate better financial position and efficient human resources.
The study selects departmental managers of these business units to collect data using qualitative in-dept interview. The study selects the participants for the in-dept interview because they have a deep knowledge of the ERP implementation procedures within their various departments. Added to the qualitative in-dept interview for data collection, the study also collects data through the quantitative survey method. The study carries qualitative and quantitative data analysis to enhance data validity and data reliability. (Coffey et al. 1996).
This study combines both quantitative and qualitative data analysis to enhance reliability and validity of the research findings.
The Table 1 reveals the different strategies that both quantitative and qualitative research carries out the analysis.

QUALITATIVE
Reliability
Quantitative analysis uses reliability to measure the instrument to ensure that the results of the research are reliable.
On the other hand, the qualitative data analysis ensures that data collected makes sense and consistence with the research findings.
Sampling strategies
Sampling strategies for quantitative analysis include random, large, representative, and use of control groups.
Qualitative data analysis uses the sampling strategies to collect data from small non-random samples, and purposeful sample population to collect rich data and information.
External Validity
Quantitative analysis uses external validity to ensure that sampling is correct and the random sampling is reflective of general population.
However, qualitative data analysis uses external validity to ensure the research is applicable to rich and phenomenon. (Gibbs, 2002).
Data collection method
The data collection method is through survey and/or questionnaires
The data collection method is through interviews.
Benefits
Data collected is relatively easy to analyze and cost efficient.
Data collected are rich and are collected within the natural environment.
Disadvantages
Data may not be rich enough to provide answers to the complex issues.( Mertens, 2005).
Data collection method is usually costly and time consuming. (Ettlie, 2000).
3.1: Qualitative Data Analysis
QDA (Qualitative data analysis) is the process and procedures of moving data into some form of interpretation, and understanding. Qualitative data analysis is also the process of removing the errors and interpreting the data collected during the course of qualitative research. The researcher uses the in-dept interview to collect qualitative data from participants, and the interview process took approximately 30 minutes. Typically, the answers from interviewees are recorded in a small voice recorder. Apart from this recording procedure, the researcher also writes all the answers from the interviewees on a small writing pad. The interview protocol was easy to read and was written with a simple English to make them easy to understand for participants. The interviewer selected respondents based on their positions within the company and the interviewees were selected based on their knowledge on ERP. There is different process that the study employs to carry out the qualitative data analysis:
First, a researcher goes through texts written on the note pad and highlights the important answers relevant to the questions. Moreover, an interviewer plays the voice recorders three times and crosscheck whether the contents written in the writing pad are similar to the contents in the voice recorder. The study uses writing procedure to put down all the data collected from interviewee, and the researcher uses the analytical procedures to put down the content of the interview. Typically, the researcher put down the summary of the data in an analytical procedure. (Merriam, 1998).
To enhance further analysis, the researcher cross checks the data to identify the bias from the response of the interviewees....
Role-based ERP systems are critical for the siloed, highly inefficient architectures of legacy ERP systems to be made more relevant, contribute greater financial performance, and lead to higher levels of overall customer satisfaction. c. Purpose of the study The purpose the study is evaluate how enterprises who adopt role-based ERP system implementations are able to attain higher levels of financial and operations-based performance vs. those that rely on silo-based, more functionally
ERP and Information Security Introduction to ERP Even though the plans of information security include the prevention of outsiders to gain access of internal network still the risk from the outsiders still exists. The outsiders can also represent themselves as authorized users in order to cause damage to the transactions of the business systems. Therefore, strict prevention measures should be taken to avoid such situations. The threats of both the hackers have been
Data Warehousing: A Strategic Weapon of an Organization. Within Chapter One, an introduction to the study will be provided. Initially, the overall aims of the research proposal will be discussed. This will be followed by a presentation of the overall objectives of the study will be delineated. After this, the significance of the research will be discussed, including a justification and rationale for the investigation. The aims of the study are to
Data Warehousing and Mobile Computing In the contemporary competitive environment, organizations are being forced to collect, store and analyze a large volume of data to make an analytical decision. However, business executives are faced with the time constraints when analyzing data, thus, data warehousing over the mobile computing have come into existing to assist in analyzing data quickly anywhere to assist in enhancing an effective timely decision. The study presents the
