Best Practices for Controlling ERP Scope and Budget

ERP projects are complex endeavors that suffer scope creep, budget overruns and schedule delays. Managing an ERP scope and budget effectively is crucial to ensuring the implementation delivers value without spiraling out of control. Here are some ways to control scope and budget on your ERP Project.

1. Establish Clear Milestone-Based Payments with Financial and Delivery Accountability

Use milestone-based payments tied to specific project deliverables. This structure encourages systems integrators (SIs) to meet defined objectives on time and within budget. Rather than paying a large sum upfront, the organization releases payments only when agreed-upon milestones are achieved.

Example:

Milestone-Based Payments: Set up milestones with clear expectations. For instance, define 20% of the payment for the successful completion of the design phase, 30% for system build and testing, and the remainder tied to user acceptance testing (UAT) and go-live. Each milestone should have detailed criteria that combine technical achievements (like completed configurations) with business-focused outcomes (such as a successful UAT with minimal defects).

Best Practice Tip: Document each milestone in the contract, including the specific criteria that must be met for payment. Require digital signature sign off of the SI and key stakeholders. This structure not only controls costs but also aligns the SI’s priorities with the project’s success.

2. Define and Communicate a Scope Change and Change Order Cap

Setting strict limits on the number or cost of change orders is critical to controlling scope. This cap encourages stakeholders to think carefully about each change, reserving them only for essential modifications that align with the project’s goals.

Example:

Change Order Cap: Define a change order budget cap at 10-20% of the total project budget. Require any changes must go through an executive approval process, including a detailed justification of why the change is necessary for the project’s success. This approach restricts change orders to high-priority requests.

Best Practice Tip: Establish this cap early and ensure all stakeholders are aware. Clearly communicate that once the cap is reached, only critical changes will be considered.

3. Implement a Tiered Approval Process for Change Orders

Not all change orders carry the same impact on budget and timeline. A tiered approval process categorizes changes by cost, complexity, and impact, ensuring that significant changes undergo thorough scrutiny while minor adjustments are approved more quickly. Example: - Low-Impact Changes (under $2,000 or less than one week impact): Approved by the project manager. - Medium-Impact Changes ($2,001–$25,000 or 1–2 weeks of time impact): Require approval from the project steering committee. - High-Impact Changes (over $25,000 or more than 2 weeks of time impact): Require executive-level approval, including a review of the change’s strategic importance. Best Practice Tip: Document the tiered approval process in the project’s governance framework, ensuring all project stakeholders understand the system.

4. Implement a Scope Freeze at Key Phases

A scope freeze is a temporary halt on new change requests at critical project phases, allowing the team to focus on delivery without distraction. This technique is highly effective in controlling both scope and budget.

Examples:

1. Design Phase Freeze: Once the design phase concludes, implement a freeze on design-related changes, allowing the project team to transition smoothly into the build phase. Only high-priority requests that affect critical functionality are allowed.
2. Pre-Go-Live Freeze: Implement a scope freeze 1–2 months before go-live to focus on testing, training, and final preparations. During this time, only emergency changes that affect business continuity or regulatory compliance are allowed, with all other requests deferred to a post-launch phase.

Best Practice Tip: Communicate freeze periods early in the project, allowing stakeholders to plan requests accordingly. Remind stakeholders of the freeze deadlines, and work with them to prioritize necessary changes in advance. Freezes should be documented in project plans and discussed regularly in project meetings.

5. Use a Change Control Board (CCB) for Rigorous Change Evaluation

A Change Control Board (CCB) is a dedicated group responsible for reviewing, evaluating, and approving or denying change requests. By adding a structured review process, the CCB ensures that only essential changes are approved, reducing the risk of scope creep.

1. CCB Composition: Include representatives from finance, IT, key business units, and the project sponsor. Each member evaluates change requests based on the project’s strategic goals, budget implications, and potential risks.
2. CCB Evaluation Process: The CCB meets bi-weekly to review all new requests. Each requestor must present a justification, including estimated cost, time impact, and expected benefits. The CCB uses a scoring system to prioritize changes, approving only those with high business value and manageable impact.

Best Practice Tip: Use templates for change requests to standardize submissions, making it easier for the CCB to assess requests quickly and consistently. Regular meetings keep changes under control without delaying progress.

6. Incentivize Scope Adherence with Performance-Based Bonuses

Incentivizing adherence to scope helps align the systems integrator and internal teams with the project’s original objectives. By offering bonuses for scope control, both parties are encouraged to focus on delivering core requirements effectively and avoid unnecessary changes.

Examples:

1. Scope Adherence Bonus for the SI: Include a 5-10% bonus in the SI contract for delivering the project within the original scope. This bonus is contingent on the SI completing the project with no more than five change orders or staying within the allocated change order budget.
2. Internal Team Incentive: Offer department heads or project managers a bonus if they maintain scope adherence, tying compensation to the number of changes avoided or deferred.

Best Practice Tip: Ensure the bonus structure is clearly outlined in the contract and project documents. Consider a tiered bonus based on the level of scope adherence to encourage continuous focus on controlling changes throughout the project.

7. Implement a Change Request Fee for Non-Critical Changes

Introducing a fee for non-critical change requests discourages stakeholders from submitting low-priority changes. This approach helps control scope by ensuring that only necessary changes are submitted.

Example:

Fee-Based Change Requests: Charge a fee of $1,000–$5,000 per change request, billed to the department or team requesting the change. Waive the fee only for critical changes that impact core functionality, business continuity, or regulatory compliance.

Best Practice Tip: Explain the rationale behind the fee to stakeholders, clarifying that it’s intended to prioritize essential changes and discourage non-critical modifications. Consider setting up an approval process to assess which changes qualify for the fee waiver.

8. Maintain a Deferred Enhancement Backlog for Non-Essential Changes

A deferred enhancement backlog captures non-critical changes that can be revisited in future phases. This backlog allows stakeholders to suggest changes without disrupting the core project scope, keeping the current phase on track while acknowledging future needs.

Example:

Deferred Enhancement Log: Create a backlog of non-critical requests, which will be evaluated after go-live or in subsequent project phases. Stakeholders can prioritize and plan for these changes based on business needs and system performance after go-live.

Best Practice Tip: Communicate the purpose of the backlog to stakeholders to manage expectations and reduce pushback on deferred changes. This approach reassures stakeholders that their requests are captured, even if they aren’t implemented immediately.

9. Require a Business Case and Cost-Benefit Analysis for Major Changes

For significant change requests, require a formal business case and cost-benefit analysis to validate the change’s necessity. This additional step helps filter out changes with minimal value or high risk, preserving scope and budget.

Examples:

1. Business Case Submission: For any change request expected to exceed $10,000 or add more than one week to the timeline, require the requestor to submit a business case. This should include the expected ROI, operational benefits, risks, and cost-benefit analysis.
2. CCB Review of Business Cases: The Change Control Board reviews each business case, assessing the change’s impact on project objectives and overall value. Only changes with a compelling business case are approved.

Best Practice Tip: Provide templates for business case submissions to simplify the process. This standardization makes it easier for requestors to present thorough justifications and for the CCB to evaluate changes efficiently.

10. Implement a Shadow Budget for Contingency Planning

A shadow budget is an allocated fund, separate from the primary project budget, that covers unforeseen costs like minor scope changes, unexpected resource needs, or emergency adjustments. The shadow budget acts as a financial buffer, allowing the project to absorb unplanned expenses without impacting the primary budget or requiring frequent budget approvals.

How to Set Up a Shadow Budget

1. Determine the Shadow Budget Size Allocate 5-10% of the project’s total budget as the shadow budget. The exact amount depends on the project's complexity, industry standards, and the historical unpredictability of similar projects.
2. Define Criteria for Shadow Budget Use Set guidelines on what qualifies as a shadow expense. Typically, this budget should only be used for unplanned costs that are necessary for keeping the project on track, such as: Minor technical adjustments needed during implementation Emergency staffing increases Additional training or change management efforts if user adoption is lagging
3. Establish Approval Processes for Shadow Budget Spending While shadow budget spending should be flexible, it’s crucial to have an approval structure to avoid overuse. Approval by a project sponsor or steering committee is common practice, with spending reviewed monthly or quarterly to ensure control.

Examples of Shadow Budget Utilization

Emergency Technical Adjustment During testing, the SI discovers a critical integration gap between the ERP and an existing financial system. Implementing this fix would delay the timeline and require additional configuration hours. The shadow budget can cover these unexpected costs without impacting the primary project budget or disrupting milestone payments.

Additional Training Needs During the project, feedback reveals that end-users are struggling to adapt to the new system, requiring more comprehensive training. The shadow budget can fund these extra training sessions, helping to improve user adoption without needing executive-level budget approval for additional funds.

Temporary Resource Addition As the go-live date approaches, the project team realizes they need additional support from specialized IT staff to handle last-minute technical issues. The shadow budget can be used to bring in temporary staff, ensuring the project remains on track without exceeding the main budget.

Best Practice Tip: Include shadow budget details in the project charter, specifying its purpose, criteria for use, and approval requirements. Regularly track shadow budget expenses to ensure transparency and maintain financial oversight.

Conclusion

Effectively controlling scope and budget is critical for a successful ERP implementation. By using milestone-based payments, implementing caps on change orders, establishing scope freezes, and incentivizing adherence to the original plan, organizations can minimize scope creep, keep budgets in check and maximize business benefit. These best practices, when consistently applied, ensure that ERP projects deliver on their promise, meeting business goals and avoiding unnecessary cost or complexity. The key to success is proactive management, clear communication, and structured processes that keep both the SI and internal teams focused on core objectives.
