This matrix model assumes a single-and multiple case studies, reflecting the different design situations, but also in the two Types of centers, there also exist with a single one or a multiple unit of analysis differences. Select one or multiple cases in a single reason for Lies in whether the case presents an important critical test for the theory, the case does it mean that one or the kinds of extreme A unique exception, or by a particular researcher can access some cases, a scientific observation can not be explored before Realm. The case studies to choose a single one or a multiple unit of analysis, it would take depending on whether the identified logical Sub-unit, or when the theoretical basis of case studies related to the nature of the above is the overall time. That is, in the group research centers, either through sampling (Sampling), or clustering technique (Cluster Techniques) to clamp-in Out of the unit selection. If just want to check out a program or the nature of the organization as a whole then it should be made With the overall design pattern. Alone in terms of business research, case studies are very common in a species of research methods, because it can The basis of academic theory, focusing on the occurrence of background and practical problem-solving process, so that theory can utilize the enterprise When the indian, but also allows researchers to acquire all of the follow-up the sequence of events. According to the above mentioned scholars point of view, in this study decided to case studies conducted, the reasons as follows:
(a) This study focused on the same kinds of ERP system in the different companies build, its causes and the result is different, If the difference is how different? To build successful, it may what are the elements?
(b) In a real environment in india, researchers are usually the event likely to manipulation of variables.
(c) This study focused on contemporary events.
In the case study method of design patterns, since multi-case design is the study of indian will be in the same package with a single one above cases. The use of multiple cases, the design will encounter a problem is that the needs of the Institute The number of cases, in the case studies and statistics related to a sample of secondary criterion is not applicable, the study sample size Should depend on research center or a theory of recovery as is now the number of cases (Yin, 1994). Therefore, this study decided to Electronic industries to conduct multiple case designs, and in line with "type three" design patterns. Explanations are as follows:
Firstly, because the evidence from multiple cases is given, usually strong and powerful, is relatively stable throughout the study (Yin, 1994).
Secondly, interviews and observation conducted by the relevant data collection may be more in-depth exploration is difficult to obtain outside the person digging the information.
Third, this study focuses on thinking the same kinds of ERP system in the build when the differences between different companies are not emphasized in the Function of the strength of ERP system itself. Because the coverage is too wide ERP system, its import process the problems faced by the indian may be more general information system Integration complex and require in-depth information on the case, appropriate to clarify the complex phenomena occurring; Secondly, this research study The main purpose was to explore the process of ERP systems into india, critical success factors and import projects carried out in the inter - Relationship with the others in order to clarify the critical success factors of implementation of the method and why the occurrence of different results, how to video sound system success or failure, and trying to find the key success factors of the implementation should pay attention to conditions. Therefore this study use of narrative (Descriptive) and exploration (Exploratory) Parallel case study method, by companies to import Practical case of ERP systems to explore the business into ERP encountered problems and their solution.
