Current evidence points to management accountants using traditional software (such as spreadsheets) for budgeting, ABC, balanced scorecards and other performance management techniques independent of, rather than integrated with Enterprise Resource Planning (ERP) Systems. While there has been some limited research on the effects of ERP systems on management accountants, this report provides a comprehensive analysis of the consequences of implementation of ERP systems for management accountants.• This report provides a theoretical basis for studying the impact of Enterprise Resource Planning (ERP) systems on management accounting and provides critical insights into the opportunities provided by ERP systems for the most efficient use of management accounting techniques.
• The seven UK case studies of ERP implementations reveal the correlation between the success of the system implementation and the development of the role of management accountants in business partners thereby identifying the changes and skills required of management accountants.

Chapter 1. Introduction

Enterprise resource planning (ERP) systems are becoming commonplace. Many studies report that about 90% of large business organisations have implemented an ERP system (Olhager and Selldin, 2003; Manufacturing Business Technology, 2008). In addition to their implementation in large enterprises, they are now implemented in many mid-sized organisations. At this time, the significant benefits that accrue to businesses that have successfully implemented ERP systems have been well documented. Yusuf et al. (2004) suggest that ERP systems offer three major benefits: (1) business process automation; (2) timely access to management information and (3) Improvement in the supply chain via the use of E-communication and E-commerce. Other benefits include information visibility, decreased costs, faster period-end closes, greater market responsiveness, better control over reverse logistics and others (e.g. Latamore, 1999; Davenport, 2000; Wallace and Kremzar, 2001; Cullen et al., 2007).

Some research is now beginning to appear that examines the effect of ERP systems on the people who use them (e.g. Granlund and Malmi, 2002; Lodh and Gaffikin, 2003; Scapens and Jazayeri, 2003). In particular, one group that is severely affected by the ERP systems is the management accountants.

Management accountants have typically been tasked to accumulate and track costs, to prepare budgets and performance reports. Current evidence points to management accountants using traditional software (such as spreadsheets) for budgeting, activity-based costing (ABC), balanced scorecards and other performance management techniques independent of, rather than integrated with ERP systems, despite many of these tasks having already been included in current ERP systems.

How have management accountants adapted to the changes resulting from the implementation of ERP systems? Do the tasks performed by management accountants change based upon the relative success of the ERP implementation? Has ERP software replaced traditional software in an ERP environment or are management accountants still using spreadsheets, etc.? There has been some research undertaken on the effects of ERP systems on management accountants and management control systems (see Fahy, 2000; Granlund and Malmi, 2002; Caglio, 2003; Gould, 2003; Hyvonen, 2003; Lodh and Gaffikin, 2003; Quattrone and Hopper, 2003; Scapens and Jazayeri, 2003). The early reports (e.g. Granlund and Malmi, 2002) are that there seems to be a decrease in the multiple data entries required compared with non-integrated accounting systems; however, the goal of having the management accountant becomes more of a business analyst has not occurred in the majority of cases.

The objective of this research project is to provide further insight into the changes resulting from the implementation of ERP systems on the work and behaviour of management accountants. This report presents our findings, focusing on the differential effects of successful as compared to less-than-successful ERP system implementations on the role of management accountants. Further, we seek to provide insight and advice to management accountants whose organisations are undergoing an ERP (re-) implementation project.

Some researchers (e.g. Caglio, 2003; Lodh and Gaffikin, 2003; Scapens and Jazayeri, 2003) argue that surveys that seek to identify the impact of ERP systems on the outcomes of the implementation process will not be able to address the complexities of the change process, and that longitudinal studies are required for that purpose. In this research we did not perform a longitudinal study, but addressed the time span issue through the design of the study.

Following three pilot case studies and responses to a postal questionnaire, an interview instrument was developed and used to conduct in-depth interviews at seven large organisations in the UK that had implemented ERP systems. In each organisation, we interviewed at least one member of the ERP implementation project team.

Although we cannot examine all of the nuances of the changes identified by the interviewees as having resulted from the ERP implementations, the interviews allow us to obtain a very good perspective of the changes that occur from implementations of this type and of how they impact both managerial accounting and the management accountant.

We agree with Scapens and Jazayeri (2003) that research should identify the opportunities created by the implementation of ERP systems for management accounting and the management accountant. We demonstrate from our findings that these opportunities are dependent upon the relative success of the ERP implementation.

Chapter 2. Background to the Study and Review of Prior Research

Many organisations have implemented ERP systems; however, the level of success associated with these systems has varied widely. In the late 1990s, many of these systems were implemented to eliminate the ‘Y2K’ crises. Unfortunately, some of these implementations only focused on replacing the financial reporting systems and ignored the benefits that could have been obtained through the design and implementation of a system that integrated the operations of the entire organisation (i.e. including accounting, manufacturing, supply chain management, etc.). The lack of integration and subsequent required upgrades (to ensure that the software will continue to be supported by the vendor), along with business combinations has resulted in most of the early ERP adopting firms re-implementing their ERP environments. Some were simply upgrades, whereas others were essentially a complete, new ERP implementation project.

It is commonly accepted by the business world that information technology should be viewed as more than just an automation of business processes; information technology can fundamentally change the way business is done. Many organisations, therefore, seek to improve their competitiveness by utilising advanced information technology, such as ERP systems. However, consistent with the argument made by Carr (2003), research indicates that organisations generally do not obtain any long-lived competitive advantage through an ERP system implementation, any benefit obtained is quickly competed away. However, this is not to say that organisations should not implement ERP systems – those that do not soon find themselves loosing ground to organisations that have successfully implemented these systems (Poston and Grabski, 2001; Hunton et al., 2003).

The implementation and subsequent operation of an ERP system is not an easy task. Without sound management of the implementation process, and without the identification of the changes an enterprise must undergo during operation, ERP systems can result in many difficulties for organisations (see Cameron and Meyer, 1998; Davenport, 1998; Deutsch, 1998). As argued in Grabski et al. (2001), ERP systems are different from traditional systems in scale, complexity, organisational impact, cost and subsequent business impact. ERP systems typically impact the entire organisation and are almost always associated with the business process re-engineering (Davenport, 2000).

Traditional analysis and design projects had minimal re-engineering and the software was written to match current processes, whereas ERP systems are implemented with minimal change to the software while significant re-engineering of business processes to match the ERP software occurs. Organisations that implement ERP must be ready to do so and many have run into difficulty because they were not organised in the correct fashion to benefit from the implementation (Yusuf et al., 2004). The costs associated with ERP systems are significantly higher than those of traditional systems and mistakes such as these can be extremely costly – for example, Dell Computers spent millions of dollars on an ERP system that had to be scrapped as it was too rigid for the expanding nature of the company (Turnick, 1999). In some cases, a failed implementation can destroy the organisation, as in the case of the FoxMeyer Drugs bankruptcy (Scott, 1999).

2.1. ERP success factors

Researchers have begun to identify the success factors associated with successful ERP system implementations. Early research into ERP implementation success factors (e.g. Holland and Light, 1999; Jarrar et al., 2000; Grabski et al., 2001; Somers and Nelson, 2001; Akkermans and van Helden, 2002) generated lists of factors but did not provide any guidance as to whether all the factors were needed, or if all the factors needed to be used with the same level of effort. More recently, Aloini et al. (2007), emphasising the importance of organisations focusing on ways to make their ERP implementation successful, looked at different approaches taken in the literature and compared them from a risk management point of view to highlight the key risk of failure factors and their potential impact on ERP projects success.

Grabski and Leech (2007) extended the research on control theory (e.g. Ouchi, 1979; Eisenhardt, 1985, 1989; Kirsch, 1996, 1997; Kirsch et al., 2002) through the use of the economic theory of complementarities (see Milgrom and Roberts, 1990, 1994, 1995). The basic issue they explored was the limitation of a portfolio of controls that were hypothesised to be used in a singular fashion when complex projects demanded the use of multiple techniques simultaneously. They examined the risks and controls associated with ERP system implementations and developed critical success factors that when used together enhanced the outcomes. They found that all the factors were necessary, and that no one factor by itself was sufficient for a successful implementation.

Based upon a survey of organisations that implemented ERP systems, they were able to aggregate the specific individual factors identified in the prior research into five overarching factors:

1. project management,

2. change management,

3. alignment of the business with the information system,

4. oversight (internal audit) activities and

5. consultant and planning activities.

Numerous controls exist within each of the five overarching categories (and some controls applied across categories, consistent with the theory of complementarity). As a result, we now have a better understanding of the complexities associated with successful ERP implementations and why some organisations, while on the surface appear to be doing the prescribed steps, are missing out on important processes.

2.2. ERP failure factors

Concerning unsuccessful ERP implementations, Aloini et al. (2007) carried out a meta-analysis of published research since 1999 and concluded that there are four broad categories of ERP system failure:

1. Process failure, when the project is not completed within the time and budget.

2. Expectation failure, when the IT systems do not match user expectations.

3. Interaction failur...
