Research on SAP Business One Implementation Risk Factors with Interpretive Structural Model


The possible risk factors during SAP Business One implementation were studied with depth interview. The results are then adjusted by experts. 20 categories of risk factors that are totally 49 factors were found. Based on the risk factors during the SAP Business One implementation, questionnaire was used to study the key risk factors of SAP Business One implementation. Results illustrate ten key risk factors, these are risk of senior managers leadership, risk of project management, risk of process improvement, risk of implementation team organization, risk of process analysis, risk of based data, risk of personnel coordination, risk of change management, risk of secondary development, and risk of data import. Focus on the key risks of SAP Business One implementation, the interpretative structural modeling approach is used to study the relationship between these factors and establish a seven-level hierarchical structure. The study illustrates that the structure is olive-like, in which the risk of data import is on the top, and the risk of senior managers is on the bottom. They are the most important risk factors.

1. Introduction

Enterprise Resource Planning (ERP) software is one of the fastest growing segments of business computing today. A large body of literature on information technology (IT) implementations has been developed during the past several decades. However, our understanding of the factors and processes that lead to ERP implementation successes or failures is still limited because ERP implementation is relatively new and is different from traditional information systems development projects [1].

A search of abstracts of scholarly articles using the keywords of project management and ERP on the following databases, namely: ABI/INFORM, ACM Digital Library, IEEE Explore, Science Direct, and Emerald Fulltext yielded only 22 articles. Out of these 22 articles, 14 articles are more closely related to the implementation of ERP systems, while the rest mention ERP but are concerned with other software or business-process-related topics. Out of the 14 extracted articles, 9 deals with success factors, models, or best practices contributing to positive outcomes of ERP implementations with project management as one of the factors. There are two conceptual articles that offer a normative project management methodology and a project model in ERP implementations. The remaining three articles all mention project management as important in ERP implementations but are mainly concerned with a variety of issues in ERP, including an agentbased approach to ERP deployments, technological discourse in organizations while undertaking an ERP project, and ERP system value as a function of a firm’s strategies and integration mechanisms [2].

Headquartered in Walldorf, Germany, SAP is the market leader in enterprise application software. Founded in 1972, SAP (which stands for “Systems, Applications, and Products in Data Processing”) has a rich history of innovation and growth as a true industry leader. SAP has more than 54,000 employees and sales and development locations in more than 50 countries worldwide. The SAP Business One application integrates all core business functions across your entire company—including financials, sales, customer relationship management, inventory, and operations. Unlike many other small business solutions on the market today, SAP Business One is a single application, eliminating the need for separate installations and complex integration of multiple modules ( Based on the work of the SAP implementation process, and combined with practical experience, SAP Business One implementation can be divided into five stages: preparation stage, solution stage, implementation stage, final preparation stage and online and support stage.

The paper is organized as follow: the Section 1 is introduction, the Section 2 is literature review, the Section 3 is research design, the Section 4 is to identify key risk factors, the Section 5 is to identify root risk factors, the Section 6 is case study, and the Section 7 is conclusions.

2. Literature Review

Christina Soh, Sia Siew Kien and Joanne Tay-Yap findings suggest the “misfit” issue may be worse in Asia because the business models underlying most ERP packages reflect European or U.S. industry practices. Procedures in Asian organizations are likely to be different, having evolved in a different cultural, economic, and regulatory context [3]. Herb Krasner have found that for your project to succeed, you must prevent problems in the following high-priority areas: 1) e-business strategy, 2) Project management approaches, 3) Complex technology and systems, and 4) End-user resistance [4]. Companies predominantly look at the functionality and quality of the products and services for evaluating ERP suppliers, which has been found across all lines of business and all countries [5]. Inevitably, customization and implementation of ERP systems became an industry on its own. Several modeling approaches are possible: 1) Reduce the effort necessary for creating the target concept by leveraging “best practice case” knowledge available in reference models. 2) Create a requirements definition by leveraging modeling techniques to detail the description. 3) Document the system requirements definition by means of conceptual modeling methods, making the business logic more understandable. 4) Leverage conceptual models as a starting point for maximum automation of system and configuration customizing [6]. The meanings of “enterprise” and “site” vary depending on unique organizational circumstances. The complexities of what are often called “multi-site” ERP implementations are discussed here. Like all computer-based information systems, multi-site ERP implementations can be analyzed in terms of levels or layers (logical versus physical, hardware versus software). At each level there are different choices to make and different criteria for evaluating the alternatives. However, the layers are interdependent: Choices at one level may limit the available choices or affect the performance of the system at another level. Therefore, organizations are generally advised to start planning multi-site ERP implementations at the strategic level before proceeding to the technical (software and hardware) levels. In practice, however, the sheer size and scale of such implementations may encourage organizations to tackle the layers independently, contributing to many failures and partial successes of these complex business and technical projects [7].

3. Research Design

First, SAP Business One implementation risk factors were found out with depth interviews and expert surveys, key risk factors were identified and root risks were determined. Finally, the research results and their applicability were analyzed with case studies (Figure 1).

4. Identify Key Risk Factors

4.1. Questionnaire Approach

The investigating scheme was protocoled after an in-depth interview and preliminary established SAP Business One implementation risk factors. Expert investigation was used to revise and complement the result of in-depth interview and establish formal survey scheme to make the result more reasonable. Questionnaire would be sent to consulting company and supervisor to a pilot investigation in the first, and then for SAP Business One suppliers, services, implementation enterprises and the information direction scholar with a purpose. Before sending out the questionnaires, we would talk to them and make them know the whole process and explain the unclear. Only the respondents had the knowledge that the questionnaire required and were interested in the questionnaire (Figure 2).

4.2. Questionnaire Design and Collection

We divided the five phases into 21 level 2 risk factors and with 73 level 3 risk factors to reflect based on the interview results. After experts’ investigation, and 20 level 2 risk factors, 49 level 3 risk factors were determined finally with five-point Likert scale.

The 49 level 3 risk factors were as follows according five stages SAP Business One (SBO).

O2) Risks of system operation assessment are follows: O21) Evaluation personnel participation isn’t positive. O22) Evaluation system isn’t reasonable.

A total of 45 questionnaires were distributed, of which, 40 questionnaires were returned for a response rate 89%, after eliminating duplicate or largely incomplete responses, we were left with a usable set of 36.

4.3. Analysis Questionnaire Reliability

All the data’s Cronbach’s alpha value from questionnaire 49 level 3 risk factors is 0.896, and then aggregate level 3 risk factors to corresponding level 2 risk factors, and calculating mean, then reliability analysis the 20 level 2 risk factors data once again, their Cronbach’s alpha value is 0.885 and reliability are very good.

4.4. Analysis Questionnaire Validity

Validity includes three types: There are surface validity, content validity and construct validity.

Surface validity. Before sending out the questionnaire formally, this paper made a pilot study on the questionnaire draft in a small scope, according to the feedback of the investigation results, we amended the questionnaire and guaranteed good validity of the questionnaire.

Content validity. Every risk factor was discussed and amended by the expert group and got recognized commonly, we ensured each items had significant difference to guarantee the effectiveness of the content through the depth interview.

Construct validity. The construction of the 49 level 3 risk factors of five stages were measured with KMO sample and Bartlett sphere to test the significant level simultaneously in order to check whether it is suitable for factor analysis. The measurement results of each secondary indexed was illustrated in Table 1 with principal component analysis and varimax to orthogonal rotating factor.

Kaiser argued that KMO less than 0.5 was not suitable for factor analysis, while KMO more than 0.9 was very suitable for factor analysis. The exploratory factor analysis and varimax orthogonal rotating was used to test whether the 49 level 3 indexes could belong to the 20 level 2 indexes (Table 2).

The accumulative variance interpretation of each stage is greater than 40% in Table 2, which satisfies the standard of judgment. The factors which characteristic value is greater than 1 were selected with orthogonal rotation to get factor load matrix according to Kaiser rule in Table 3.

Each factor loading corresponding to each index is above 0.5, therefore, it has good construct validity.

4.5. Questionnaire Results

Top ten risks in descending were illustrated in Table 4. The results were in the following: Senior management leadership (I4), Project management (I3), Process improvement (S2), Implementation team (P1), Process analysis (S1), Risk-based data (I1), Human resources (I5), Change management (S3), second development (S4), and Data import (F2).

Interpretive Structural Modeling (ISM) process, which enables groups to work together to construct those nonlinear patterns that no one or no group working without

this powerful tool could construct with the high quality of what this process makes possible. That is because, when completed, it is a linked collection of Aristotle’s syllogisms, often containing several hundred of these. Moreover, from the behavioral point of view, every statement readable from the structural model represents a consensus point of view of the developing group. This is remarkable, since ample data is available to show that when groups begin to work on complexity their views are all over the place, so there is essentially no consensus at the outset. It develops gradually as the Interactive Management system proceeds to unfold with a group of participants.

5. Identify Root Risk Factors with Interpretive Structural Model

5.1. The Establishment of the Interpretive Structural Model Team

We use the ISM to find the root risk factors [8]. The major sequence of events of an ISM is the following: (1) the theme is selected, (2) the developer is identified, (3) the elements and contextual relations are identified, (4) the project leader is identified, (5) the ISM program is entered into the computer, (6) adequate computer time is allocated, (7) the facilities are made ready, (8) the session plan is completed, (9) the computer contains the elements and the contextual relations, (10) the session begins, (11) the element set is edited, (12) the reachability matrix is completed, (13) the total structure is now available, (14) the amendments are completed, and (15) the final structure is approved.

5.2. Discussion on the Relationship of SAP Business One Implementation Risk Factors

The discussion were done in GB company’s colleagues and its clients without leadership, there are nine experts put forward their valuable opinion, among which there are seven provide the data of adjacency matrix. The results were further discussed among the experts of Guangzhou JZ consulting company to establish the adjacency matrix.

5.3. Analysis of the Relationship of SAP Business One implementation

“X” indicates the row and column factors have mutual influence, “R” indicates the row factors affect the column factors, “C” indicates the column factors affect the row factors, the blank indicates the row and column factors have no mutual relationship (Table 5). We can construct reachability matrix R, for each Ki element with Table 5, we get the following set:

P(Ki) = { Kj mij = 1 };

Q(Ri) = { Kj mji = 1 };

P(Ki) ∩ Q(Ki) = T(Ki)

Among them, P(Ki) is called, reachability set, that is, starting from Ki element to all the elements set that is able to reach; Q(Ki) is called first set, that is, all the elements set that can achieve the Ki elements; T(Ri) is called common set, that is, the elements set which not only belong to reaching set, but also to first set (Table 6).

5.4. Recognition of the Root Risk Factors of SAP Business One Implementation

According to the hierarchy division of SAP Business One implementation risk factors, we build the following ISM model of SAP Business One implementation risk factors (Figure 3).The data import risk is illustrated the direct reason to determine whether SAP Business One implementation is successful in Figure 3. Senior managers lead risk, which is the root risk factor, influence the success or failure of SAP Business One implementation from the start and through multiple stages. Each level risk factors is distributed to the different stage of SAP Business One implementation, the relationship among these risk factors is cross-phase stagger.

6. Case Study

DH company was founded in 2009, which integrate research and development, independent innovation, production and marketing as a whole, with gas stoves series products for the leading modern life electric appliance enterprise.

Today, the problems of DH company are various department sharing data and information low, and material code and name is not unified to result the dynamic data not unified and inaccurate. Warehouse department can’t grasp the warehouse inventory and provide the information for the production planning department timely and accurately, the inventory of portion parts is too large to be effective controlled. The production planning department can’t control the accurate material inventory information and generate a total reports of production schedule, the BOM provided by the research and development department is imperfect, which influence the accuracy of program scheduling. The purchasing plan management of purchasing department is confusion and can’t implement centralized and unified purchasing plan effectively. The sales department doesn’t have normative documents and detailed marketing plans, the customer information without special management. The company doesn’t have information management department and software and hardware maintenance work are outsourced. 

There was the enterprise internal LAN in DH company

6.1. DH Company SAP Business One Implementation Risk Factors

The findings were in the following with analysis and research:

1) DH company didn’t organize their own implementation team, over-reliance on consultants implementation team. When the problems appeared during practice, they couldn’t solve them effectively, which affected the progress of SAP Business One implementation obviously.

2) DH company’s senior leadership didn’t take to SAP Business One implementation seriously to be resistance from lower staffs, new process could’t be implemented and SAP Business One project was suspended several times.

3) GB company had less developers, which were more fluidity, they had poor communication with the persons concerned in DH company and made mistakes in understanding the customer needs to result frequent revision in the secondary development and the progress was slow, and affect the whole progress of the project.

4) The basic data management of DH company was confusion, such as the production BOM table is given by the research and development department, but the information of the BOM table was sketchy and the production department should base the past experience to produce and result in that the production BOM was different from R&D BOM, and R&D BOM couldn’t be applied into production effectively in the SAP Business One system.

5) DH company project management didn’t control the cost, and there was no comprehensive plan on time and didn’t make adequate preparations for the implementation, all the matters and time were arranged by the implementation consultant entirely, the project once was out of control and couldn’t to be continued several times.

6) The senior managers considered that SAP Business One should solve all the problems that the enterprise had, but didn’t pay attention to the whole project implementation and just wait for the results and SAP Business One’s on-line, ignoring SAP Business One’s instrumental.

7) DH company executives were not really involved in the project implementation and staff involved in the project didn’t go through rigorous training, and the whole process was like a mess and the team cohesion was quite low.

8) Only the data is successfully imported, can the whole SAP Business One system operate normally. But DH company’s data had not been provided, therefore the project implementation couldn’t be continued.

6.2. Questionnaire Results

This paper constructs the hierarchy figure of SAP Business One implementation risk factors of DH company were illustrated in Figure 4.

1) Senior managers didn’t pay attention, therefor the coordination of human resource improper and process improvement blocked. They didn’t participate in the discussion of the meeting, which resulted the attitude of key personnel of various departments were not positive. Or they only sent the personnel with weak ability to involve in the project implementation and the process improvement was resisted by the lower staff.

2) Lacking of human resource and the project implementation team couldn’t be organized and the project management was confusion. The staff of the DH company not only implemented the SAP Business One project, but also engaged in their previous work, thus their time and energy couldn’t meet the need of the whole implementation of SAP Business One project. Besides, it was difficult to coordinate their various jobs and made the project management mess.

3) The project management was out of control, the process improvement and the secondary development changes was frequent. The senior managers of DH company assigned an administrative director to be responsible for the whole project, but didn’t empower the project leader without supporting of an efficient implementation team, and the whole project management went over the right scope of the project leader, but the process modification should be the approval by the senior managers.

4) The senior managers didn’t pay attention to the basic data maintenance and the data couldn’t be imported. What’s more, they didn’t pay much attention to

Figure 4. The hierarchy relationship among the risk factors of SAP Business One project implementation.

the process of SAP Business One implementation and their work attitude of the subordinates was unenergetic, the process of basic data settling was very slow and/or the data format was not reasonable, therefore data imported often was delay and slow.

5) The workload of the twice development was large and the data import frequently went wrong. Because the workload of twice development of DH company had a lot work to do, and the data was frequent imported, and the function of the twice development may not be very perfect, and there may be some bugs in the interface design of each function, which lead to data sharing problems.

In one word, the risk factors of DH company mainly included the following: senior leader, project management, process improvement, implementation team, basic data, human resource, twice development, data import. Research results illustrated that the SAP Business One implementation risks and the relationship among them existed indeed, and the specific enterprises may only have part of the risks.

7. Conclusion

In one word, the risks factors of SAP Business One implementation were identified, then the relationship between various risk factors were studied, and the root factors were also figured out. The case study gave some evidences for our findings. The main purpose was to figure the existence of various types of risk factors in SAP Business One implementation out in order to effective control them in the future. Of course, there was a long way to go.
