Case Study: ERP Change Management for Midsize Defense Contractor

     Joseph Robinson    |    ERP Change Management


Fortune 500 companies typically bring on global consulting firms, like McKinsey, BCG, Bain, Deloitte, and Accenture, or boutique consulting firms specializing in ERP Change Management to thoroughly analyze their unique business challenges and competitive situations. These firms provide strategic recommendations based on consulting frameworks, subject matter expertise, benchmark data, KPIs, templates, and other tools developed from past client work. We followed this management consulting approach for this case study.

TLDR A midsize aerospace defense firm struggled with an outdated ERP system amid rapid expansion, leading to inefficiencies and poor decision-making. The successful implementation of a new ERP system resulted in a 20% reduction in operational costs and an 85% user adoption rate, highlighting the importance of effective Change Management and continuous improvement processes.

Reading time: 8 minutes

Consider this scenario: A midsize firm specializing in aerospace defense is facing significant challenges in adapting to a new Enterprise Resource Planning (ERP) system.

This defense contractor has recently expanded its operations and increased its workforce by 30%, leading to complex project management and procurement processes. The organization's existing ERP system is outdated and not scalable to meet the demands of its growing operations, resulting in inefficiencies and a lack of real-time data for decision-making. The company seeks to manage the change process effectively to ensure a smooth transition to a new, more robust ERP system.



Upon reviewing the situation, it's hypothesized that the root cause for the organization's business challenges may be twofold: firstly, the lack of an ERP system that can scale with the organization's growth, and secondly, an insufficient change management strategy that addresses the human factors involved in transitioning to a new system. These initial hypotheses will guide the strategic analysis and provide a foundation for more in-depth investigation.

Strategic Analysis and Execution Methodology

The methodology for addressing ERP Change Management involves a structured 5-phase process that ensures thorough analysis, planning, and execution. This proven approach aligns with industry best practices and facilitates the transition while minimizing disruption to business operations.

  1. Needs Assessment and Strategy Alignment:
    • Identify key organizational goals and how a new ERP system can support them
    • Analyze current ERP usage and identify gaps in functionality and performance
    • Develop a clear vision and strategy for the ERP transition that aligns with business objectives
  2. Process Mapping and Systems Selection:
    • Map existing business processes and identify opportunities for optimization
    • Conduct a thorough market analysis to select the ERP system that best fits the organizational needs
    • Engage stakeholders across the organization to ensure buy-in and support
  3. Change Management Planning:
    • Develop a comprehensive change management plan that includes communication, training, and support strategies
    • Anticipate employee resistance and plan for ways to address it
    • Prepare the organization for change by setting expectations and involving employees in the transition process
  4. Implementation and Training:
    • Execute the implementation plan with a focus on minimizing downtime and maintaining productivity
    • Provide detailed training for all users to ensure a high level of competency with the new system
    • Monitor progress and make adjustments as necessary to ensure successful adoption
  5. Post-Implementation Review and Optimization:
    • Conduct a post-implementation review to assess the success of the ERP transition
    • Identify any issues or areas for improvement and develop a plan to address them
    • Establish a continuous improvement process to ensure the ERP system evolves with the organization's needs

ERP Change Management Implementation Challenges & Considerations

When considering the adoption of a new ERP system, executives often question the alignment with strategic objectives. It's crucial to ensure that the selected ERP system can scale with the company's growth and adapt to future challenges. Moreover, executives are concerned about the impact on operations during the transition. It is therefore essential to meticulously plan and execute the implementation to minimize disruption. Lastly, there is the consideration of return on investment. The benefits of the new ERP system should outweigh the costs within a reasonable timeframe, through increased efficiency and improved decision-making capabilities.

The expected business outcomes after full implementation of the methodology include streamlined operations, enhanced real-time data analytics for better decision-making, and a more agile organizational structure. These outcomes should lead to a reduction in operational costs by up to 20% and an increase in project delivery efficiency.

Potential implementation challenges include resistance to change from employees, data migration issues, and system integration complexities. Each of these challenges requires careful planning and management to mitigate risks and ensure a smooth transition.

ERP Change Management KPIs

KPIS are crucial throughout the implementation process. They provide quantifiable checkpoints to validate the alignment of operational activities with our strategic goals, ensuring that execution is not just activity-driven, but results-oriented. Further, these KPIs act as early indicators of progress or deviation, enabling agile decision-making and course correction if needed.


In God we trust. All others must bring data.
     – W. Edwards Deming

  • System Downtime: Measures the amount of time the ERP system is unavailable during the transition.
  • User Adoption Rate: Indicates the percentage of employees effectively using the new system post-training.
  • Process Efficiency Gains: Captures the improvements in business process efficiency following ERP implementation.
  • Cost Savings: Quantifies the reduction in operational costs as a result of the new system.
  • Return on Investment (ROI): Calculates the financial return on the ERP investment over time.

Implementation Insights

Throughout the implementation process, it is vital to maintain clear and consistent communication with all stakeholders. According to a McKinsey study, successful change management programs are characterized by active and visible sponsorship from leaders, tailored communications, and a well-defined vision for the future. These insights are fundamental to ensuring that the organization fully embraces the new ERP system.

Strategic Alignment of ERP Systems

Ensuring that the new ERP system aligns with the strategic goals of the organization is paramount. This requires a deep understanding of the company's long-term vision and how the ERP can be a catalyst for achieving these objectives. It is not just about replacing old technology with new, but about enabling the business to operate more effectively and to innovate. A study by Gartner highlighted that 75% of all ERP projects fail because of a lack of clear alignment with business strategy and inadequate change management.

To avoid this pitfall, the strategy for ERP implementation should be developed in close collaboration with key stakeholders from various departments, ensuring that the system supports their needs and drives the business forward. The ERP should be seen as a strategic investment rather than a cost, with the potential to provide a competitive advantage through integrated and optimized processes across the organization.

Minimizing Operational Disruption During Transition

Minimizing disruption to operations during the ERP transition is a critical concern. The implementation plan must be meticulously structured to ensure business continuity. This involves a phased roll-out strategy, where the ERP system is implemented in stages, allowing for adjustments to be made based on feedback and performance. According to Deloitte, using a phased strategy can reduce implementation risk by up to 30%, as it allows for iterative learning and adaptation.

Another key element is to have a robust contingency plan in place to address any unexpected challenges that may arise during the transition. This includes having a dedicated team to monitor the implementation process and respond to issues in real-time. Furthermore, engaging with end-users early and often throughout the project will help to identify potential problems before they impact operations.

Measuring Success and ROI of ERP Implementation

Measuring the success and return on investment (ROI) of an ERP implementation is crucial for justifying the endeavor. Success metrics should be established from the outset, focusing on both financial and non-financial outcomes. According to PwC, a successful ERP implementation can lead to a reduction in operational costs by 20% and improve decision-making speed by up to 36%. However, these benefits often take time to materialize, and the ROI calculation should consider the total cost of ownership over several years.

Non-financial metrics, such as user satisfaction and system adoption rates, are also important indicators of success. These metrics can provide insights into the effectiveness of the change management strategy and the degree to which the ERP system is enhancing business operations. Regularly reviewing these metrics post-implementation will help to ensure that the ERP continues to deliver value to the organization.

Addressing Resistance to Change

Resistance to change is a natural human response, particularly when it comes to significant changes such as an ERP implementation. It is critical to understand the underlying concerns of employees and to address them head-on. Bain & Company's research indicates that companies that excel in change management are four times more likely to report success than those that do not. This involves clear and transparent communication about the reasons for the change, the benefits it will bring, and the support available to employees throughout the transition.

In addition to communication, providing comprehensive training and involving employees in the implementation process can help to alleviate fears and build a sense of ownership among the staff. By creating a culture that values continuous improvement and is open to change, organizations can overcome resistance and foster a more adaptable workforce.
