6 Key Strategies for ERP Implementation

Adding an ERP software to your business can provide many benefits, such as automating time-consuming manual tasks and streamlining back office operations. But before you can roll out your new ERP, you will need a good strategy in place to prevent costly problems during implementation.

The most common ERP implementation strategies are:

• Big Bang
• Phased Rollout
• Pilot Rollout
• Parallel Adoption
• Hybrid
• SaaS

When planning to implement a new ERP, it is always best practice to keep these three factors in mind:

1. Current Processes Replacement: Evaluate what the new ERP will replace. Are you moving away from manual, pen-and-paper methods? Transitioning from an older existing ERP system? Or integrating multiple, either connected or independent, systems?
2. ERP System Scale: Determine the scope of the ERP implementation. Will it be limited to just the accounting module, or are you planning to deploy the full range of available modules?
3. Data Synchronization Needs: Assess the extent to which your current procedures require data to be synchronized and shared across different departments or modules. The more modules that require shared data, the less flexible your implementation strategy will be.

ERP Implementation Strategies

Each ERP implementation strategy offers distinct advantages and challenges ranging from cost-effectiveness and adaptability to complexity and speed of implementation. Find which strategy aligns best with your implementation plan.

Big Bang

The big bang implementation approach is when an organization adopts and deploys the entire ERP across all operations in a single, comprehensive implementation event. This switchover reduces problems from working with duplicate systems, making implementation quicker and potentially less costly. However, it will be difficult to train everyone in the company simultaneously, making rolling back the implementation much more difficult.

Phased Rollout

Unlike big bangs, phased rollouts occur slowly over months or years. Sometimes, the phased rollout is called the “mini big bang approach”. This strategy is meant to ease learning curves on the new ERP as much as possible and smooth out the transition process. There are a few different types of phased rollouts, such as:

• By module: Implement the ERP system one module at a time, starting with the modules that return the most ROI or are easiest to implement.
• By business priority: Prioritizing implementation in areas that require regulatory compliance or have strict timeframes.
• By department: Deploy the ERP department by department, allowing implementation teams to optimize the process for each area.
• By geographical location: Implement the ERP in a single location and test it out before moving on to other locations. This method is mostly used for large multinational companies.

Parallel Adoption

The parallel adoption rollout plan involves running any existing legacy system alongside the new ERP for an extended period. This method provides users with a familiar fallback while they adjust to the new system. If errors occur while implementing, the old system can be referenced or utilized during the transition. However, this strategy leads to almost double the work as employees have to use both systems at once.

Pilot Plan

Sometimes, only one part of the business will benefit from an ERP implementation. In those situations, the ERP is only set up for that area as a trial before moving on to full implementation. This works best when a team of users can try out the software, find potential issues, and develop workarounds or address problems directly with the vendor.

Hybrid

Next, there are hybrid strategies, which combine any of the above to create a completely custom implementation plan. For example, “mini” big bangs are part of a phased rollout implementation. Entire departments can adopt a new ERP without disrupting work in another area of the company. And a pilot plan might work if there are multiple offices and corporate wants to run a trial on multiple options.

Software as a Service

Software as a Service (SaaS) ERP implementation involves deploying an ERP system hosted on the cloud and accessed over the internet. This model allows ERPs to be implemented virtually anywhere without needing a large IT infrastructure to manage it. SaaS implementations can utilize any of the methods discussed above. The software vendor will manage, maintain, and update the ERP as needed. Training is usually done virtually but can also be hybrid if vendors allow in-person training.

How to Create an Implementation Strategy

In order to select the right implementation strategy, these are a few things to consider based on your organization’s operational goals:

• Industry Requirements: Different industries have unique requirements, such as specific safety regulations or compliance standards. Consider whether an ERP will need to cover any of these.

• Organization size: Organizational size greatly influences the implementation strategy. Determine the number of active users as concurrent users will increase complexity. Less complex implementations may benefit from the Big Bang method, while more complex implementations may find the phased and parallel adoption method better.

• Costs: The implementation budget is a critical factor. It determines if any extra add-ons or customization can be added. Be sure to consider if the business has a budget for a one-time implementation cost like Big Bang. If budget constraints are a concern, phase out the implementation costs over time.

• Risks: Assess the impact of potential issues arising from the new ERP software, such as data being lost or duplicated or with human error during user training. Businesses reliant on 24/7 system operations may opt for a less risky strategy, like parallel adoption. Research what can happen if your ERP implementation goes wrong.

• Rate of ROI: Determine your ROI (return on investment) priorities. If immediate ROI is a priority, consider a phased approach, where you can implement the modules that can benefit the business immediately.

By taking all these factors into consideration during the preplanning stage, you can get the best return on investment from your ERP. For instance, a global enterprise with thousands of employees might consider a pilot program at one local office to reduce risk. A small startup might opt for a big bang approach because it’ll be cheaper to implement.

Additional Best Practices

Once you’ve selected the best strategy for your needs, you can focus on the next steps of ERP implementation plan:

• Installation: This is the time to make sure you have the right hardware for your new ERP.

• Configuration: Consider adapting the raw functionality of an ERP to your specific security requirements, workflows, and business needs

• Customization: Related to configuration, determine if any extra add-ons are necessary to cover more functionality.

• Data Migration and Conversion: Determine the best way to import data from your legacy system.

• Integration: Finally, ensure clear communication between existing software and your new ERP.

With all these elements taken into account, you can create the best ERP implementation strategy for your business.
