It simplifies the decision-making process for departmental managers, enabling them to trust the data to make crucial business calls.

Here are five reasons why an ERP implementation plan is essential for your organization:

The global ERP software market was valued at USD 71.41 billion in 2023 and is projected to grow to USD 238.79 billion by 2032, with a compound annual growth rate (CAGR) of 14.4%​ (Fortune Business Insights)​. This demonstrates the value of investing in robust enterprise resource planning software and focusing on effective digital adoption strategies to drive digital transformation and enhance technology adoption.

A well-planned ERP implementation is vital for modern businesses. By centralizing information, improving employee performance, enhancing tracking capacity, providing detailed analytics, and boosting ROI, an ERP system becomes an indispensable tool for organizational success.

ERP Implementation Failure Rate

According to McKinsey, 75% of all ERP projects fail to meet their goals, with 74% taking longer than expected. An ERP project is not just a technical change but a cultural one. ERP failures can disrupt the whole organization, and, in some cases, the results could be catastrophic.

A famous failed ERP implementation example came in 2019 when vehicle management company LeasePlan abandoned its migration to an SAP-based ERP system after numerous project delays and change management challenges. This caused the business to write off $100 million in project costs and start again from scratch. The project’s catastrophic failure was attributed to poor planning, which caused the company to develop software that would ” not be fit for purpose in the emerging digital world in which [it] operated.”

A survey conducted by Deloitte identified ten barriers to ERP implementation. The major causes of concern are resistance to change, inadequate sponsorship, unrealistic expectations, and poor project management. These factors highlight the importance of meticulous ERP planning and effective change management strategies.

10 Key Phases in a Successful ERP Implementation Plan

A typical ERP implementation plan can be divided into ten key phases that cover the entire ERP software application lifecycle, from concept to deployment and support of the live system and its users.

Rigorously following these ERP implementation steps will ensure that your ERP implementation has the best chance of success.

1. Discovery

The discovery phase is an extensive research process that gathers information on an organization’s current systems and processes to detail the problem landscape before any ERP solutions are decided upon. This phase provides a solid foundation for the entire ERP implementation process by developing a shared understanding of what a successful implementation will look like.

The discovery phase includes developing technical specifications to inform the selection of an ERP system and whether this would be best delivered on-premise or using cloud infrastructure. The Discovery team comprises senior stakeholders, project managers, technical leads, external consultants, and representatives from across multiple departments. The team should represent everyone involved in developing or using the system.

2. Analysis

After the information has been gathered during the discovery phase, a detailed analysis will be conducted to determine the business case for implementing an ERP. Typically, the outcome of this is a detailed business case that outlines project objectives and how these will be achieved through the ERP implementation plan. Developing a business case allows an organization to evaluate the benefits, risks, and costs of the ERP implementation process.

3. Planning

Implementing ERP software is probably one of the biggest digital transformation programs a business will undertake. It’s, therefore, vital that an ERP implementation plan is created to document the resources required, timelines for implementation, and how the change will be managed.

a. Resources: As part of the ERP implementation plan, you will need to select the implementation team that will be responsible for delivering the project. This team will comprise both technical and non-technical members who will be involved in developing the software and providing feedback on its viability. It’s extremely important to include stakeholders from across the organization in the implementation team, as you will need to involve software end-users in the design, development, and testing phases to ensure the final solution is fit for purpose.

b. Change Management Plan: Your change management plan will document the tasks required to successfully move from your current fragmented systems to the new ERP system. This will include tasks and milestones around data migration, QA and testing, budget forecasting as the project progresses, and end-user training once the new system is live. Alongside outlining the implementation roadmap, milestones, and tasks, your change management plan should also include guidelines around general communication, how urgent issues should be escalated, and how progress will be tracked.

c. Budget Forecasting: As with other large-scale software projects, it can be easy to go over budget when implementing a new ERP system. You must budget realistically and anticipate that some roadblocks may occur during the implementation process. It’s therefore advisable to set aside a reasonable amount of contingency in your budget from the outset to cover unexpected costs and delays. This contingency can be reviewed throughout the implementation process to ensure sufficient and adjusted upwards or downwards to reflect project progress.

4. Design

The design phase of the ERP implementation process takes the discovery and planning phases results to develop a detailed functional design that outlines how the ERP will enable new workflows and processes from an end user’s perspective. A key output of the design phase includes process maps, which visually describe the flow of work the system will allow and how the end-user will experience the ERP system.

This can be coupled with UX/UI wireframes to show how content and functionality will appear within the software. Again, getting feedback from end-users at this stage is vital, as any confusion over how they interact with or use the software may impact its successful implementation.

5. Development

Once the system and design requirements have been validated, it’s then time for the development phase to begin. Developers will configure the chosen ERP software to match functional requirements, process flows, and wireframes. Typically, this involves a high level of customization to meet an organization’s exact requirements.

Alongside writing new software, it’s essential that developers also write clear documentation throughout the development process. This ensures that no knowledge is lost after the development phase and that future changes to the ERP system can be made with a full understanding of how the system was initially developed.

6. Migration

During the migration phase, the implementation team will start planning the data migration from legacy systems into the centralized ERP system. This can be incredibly complex, as legacy systems store data in different formats and database types.

To ensure a successful migration from these older systems, the implementation team will need to develop clear protocols for handling incomplete or missing data and ensure that erroneous data is cleaned up or removed before migration.

7. Testing

Depending on the development processes used, technical testing of the system will occur throughout the development process either with each new deployment of the system or at key specified intervals.

The QA or testing team will check each part of the new ERP system for bugs and data integrity, alongside running user testing to ensure that end users are satisfied with the software. User testing is a good way to begin the training process and ensure the ERP system will succeed after launch.

8. Training

A successful ERP training program will make it easier for existing employees to adapt to the new system and should be considered a key phase in the ERP implementation process. Alongside training employees to use the new system, organizations should also consider how they can help employees adapt to more comprehensive business process changes. As one of the benefits of ERP systems is improved efficiency, organizations should also consider how they will retrain and redeploy employees whose workloads will be reduced by a successful ERP implementation.

Traditionally, training includes onboarding materials and peer support, webinars and live classes, e-learning platforms, written documentation, and newer and more effective means of training, such as a Digital Adoption Platform. It’s important to offer a range of engaging training materials to cater to different learning styles and skill levels.

9. Deployment

As ERP systems can range in scale, the process of “going” live may alter based on available resources.

a. All at once

An all-at-once, or major release, involves a mass switchover to the new system all at once. This typically happens on the same day and requires full alignment across the entire organization.

b. Phased

A phased approach packages up the transition into discrete modules or units that can be aligned around departments or business functions. While a phased approach can take longer, it does provide more flexibility to test individual parts of the ERP system as they are pushed live.

c. Parallel

In a parallel deployment, the legacy and new systems are run side by side to ensure that the new system is fully functional before the old one is depreciated. This reduces the risk of data loss; however, it is more expensive as resources are required to run and operate both systems.

10. Support

Once the ERP system is live, it will require long-term support and maintenance to remain fully operational throughout its lifespan. This will include fixing bugs and performance issues, fine-tuning data flow, and introducing new data sources. After a new system is deployed, organizations should also evaluate its success against the original business case by analyzing the return on investment, efficiency savings, and staff satisfaction with the new system. 

Main Costs in an ERP Implementation

The largest cost in an ERP implementation is undoubtedly tied to the underlying cost of the software and hardware. This includes:

Alongside the technology costs, you will also need to factor in personnel costs for the duration of the project:

After the initial implementation is finished, you will also have ongoing costs to maintain and support the new system:

Before you start the implementation planning process, it’s extremely important to draw up a realistic budget that encompasses all of the costs above. This will help align stakeholders and ensure that everyone understands the scope and scale of the project.

Alongside drawing up a rigorous budget, it is also important to forecast the positive financial impact the new ERP system will have on the business, such as reduced operational costs or improved efficiency. 

ERP Implementation Best Practices

Implementing enterprise resource planning (ERP) systems can be arduous, but organizations can take several steps to ensure that new systems are implemented successfully. Here are some ERP implementation best practices to follow: 

i. Get executive buy-in

Successful ERP implementation requires cross-functional collaboration and reallocating budget and resources throughout the implementation process. Getting executive buy-in ensures senior stakeholders understand the long-term benefits and how this will impact top-level business goals such as revenue and profitability. Successful buy-in ensures executives are fully committed to seeing the project through, from planning to long-term support. 

ii. Focus on business outcomes over technology

The primary focus of most technology projects is on the technology, not the wider impact, which leads to decisions being made through the lens of technology alone. This can result in the bigger picture being missed and misalignment between the technical solution and what an organization wants to achieve. Instead of looking at technology alone, companies should focus on the business outcome they are trying to achieve and make decisions through the lens of their ultimate goals, not software.

iii. Clearly define system requirements

One of the cornerstones of success in ERP system integration is ensuring that system requirements are fully understood and documented before a line of code is written. This is why the discovery and planning phases are so important, as they provide a rigorous process for gathering stakeholder input from across the organization on feature requests, current pain points, and potential future gains. 

iv. Select the right team members

To ensure your system requirements are fully fleshed out, selecting a diverse cross-functional team that is representative of all departments across your organization is important. Alongside having varied input from various roles, it’s also extremely important to have capable project managers and project leads to ensure key milestones are met and that the project continues to progress according to schedule. 

v. Devise a change management plan

Complex changes across an organization can result in disconnected employees and poor productivity as people struggle with new systems they don’t understand. That’s why it’s vital to have a robust change management plan that incorporates training, streamlined communication, and clear business rules.

vi. Set a realistic timeline and budget

While it’s important for ERP implementation plans to progress at pace, budgets and timelines need to be realistic and reflect the unknown nature of some parts of the implementation process. Estimates for timescales should include contingencies at each stage that can be utilized, and budgets should include at least a 25% contingency for unexpected costs. 

vii. Clean data before migration

It’s important to make sure the formatting of the data in a new ERP system is correct before importing data from your existing system. Cleaning legacy data before migration should ensure existing tables and databases are correctly formatted before they are imported into the new system, along with removing redundant data that provides little value. 

viii. Test system before deployment

Testing your ERP system before deployment is important to ensure that it is fit for purpose and can replace your legacy systems. This will include unit testing for each part of the system, integration testing to ensure that these parts work together, and system testing to ensure that the system operates as expected. Alongside technical testing, it’s also important to develop a full UAT (user acceptance testing) plan that allows actual end-users to test the ERP system before it is fully implemented. 

ix. Invest in employee training and adoption

According to recent surveys regarding ERP budget calculations, 65% of companies require additional modifications to improve efficiency and usability. It’s, therefore, extremely important to determine a sufficient training and adoption budget upfront to support users in transitioning to the new system.
