Mapping Functions to Company Goals

Too many process models start as vague diagrams that never answer the real question: what does this actually achieve for the business? EPC function mapping solves that by forcing clarity between actions and outcomes. When you map functions directly to measurable objectives, you turn abstract workflows into strategic tools.

Over two decades of modeling enterprise systems taught me one core truth: processes without alignment are just busywork. The moment you assign a function to a KPI—like reducing order processing time or increasing invoice accuracy—you shift from documentation to decision-making.

This chapter shows how EPC function mapping transforms abstract workflows into actionable intelligence. You’ll learn how to identify high-impact functions, link them to business goals, and use that alignment to uncover inefficiencies. It’s not about adding more steps—it’s about ensuring every step counts.

Why EPC Function Mapping Matters

Most business processes are modeled without considering their strategic purpose. The result? Diagrams that look complete but fail to drive improvement.

Function mapping bridges that gap. It forces you to ask: what does this function achieve? Not just what it does—but how it contributes to measurable outcomes.

Real-world insight: The invoice delay issue

I once reviewed an EPC model for a logistics company where the procurement team spent 30 minutes per invoice verifying vendor data. The function was labeled “Verify supplier details.” But when we mapped it to goals, it became clear: this task wasn’t improving accuracy—it was delaying payments, hurting supplier relationships, and increasing late fees.

Reframing the function as “Validate supplier compliance before invoice approval” tied it to the KPI: “reduce invoice processing time by 25%.” We then challenged the necessity of manual verification and found that automated checks covered 90% of cases. The process was simplified. The outcome: 32% faster approvals.

That’s the power of alignment: it reveals waste, not by inspection—but by purpose.

How to Map Functions to KPIs

Mapping functions to KPIs isn’t a one-time exercise. It’s a disciplined process of translation: from task to target.

Use this 4-step framework to build clarity:

1. Identify the function in clean, active language. Avoid passive or ambiguous terms like “process” or “handle.”
2. Define the business goal the function supports. Is it speed? Accuracy? Compliance? Cost reduction?
3. Link to a measurable KPI. For example: “Reduce order validation time” → “Achieve 90% of orders validated within 1 hour.”
4. Validate the match. Does the function genuinely affect the KPI? If not, revise or remove it.

Each step ensures that every function in your EPC diagram is not just visible—but valuable.

Example: Customer Onboarding Process

Function	Business Goal	Target KPI	Alignment Check
Verify customer identity documents	Ensure regulatory compliance	100% document verification completed before account activation	✅ Strong — directly impacts compliance
Collect customer address details	Enable accurate delivery	95% of addresses validated within 24 hours	✅ Supports delivery KPI
Send welcome email	Improve customer experience	90% of new customers receive email within 10 minutes	⚠️ Weak — email timing not controlled by this function

Here, the email task was misaligned. The actual function should be “Trigger customer onboarding email after identity approval.” That change makes the KPI measurable and the function accurate.

Align Business Goals EPC: A Decision Framework

Not every function needs to map to a KPI. But every KPI must be traceable to at least one function. Use this decision tree to determine if a function should stay.

• If the function directly affects a KPI → keep and prioritize.
• If the function indirectly supports a goal but has no measurable impact → reframe or remove.
• If the function has no connection to any business goal → eliminate. It’s noise.

When I led a process redesign at a financial services firm, we mapped 127 functions from an EPC. Only 68 had a clear link to a KPI. The rest were either duplicative, procedural, or unrelated. Removing 59 functions cut process length by 33%—and reduced errors by 41%.

That’s not optimization. That’s precision.

Practical Tips for EPC Process Efficiency

Mapping functions is only half the battle. Efficiency comes from design.

Here’s what I’ve learned from modeling over 200 EPCs:

• Use active verbs in function names: “Process,” “Verify,” “Approve”—not “Process Request” or “Task.”
• Shorten labels where possible. Long labels obscure the logic. “Verify supplier compliance before invoice approval” → “Verify supplier compliance.”
• Group functions by goal. In a single EPC, functions supporting “customer onboarding” should be visually clustered. Use color coding or grouping boxes.
• Tag functions with KPIs in a legend or annotation. This helps reviewers and stakeholders see the strategic intent.
• Revisit alignment quarterly. As business goals shift, so must function mapping.

These aren’t just best practices—they’re survival tools for process transparency.

Common Pitfalls and How to Avoid Them

Even experienced modelers fall into traps. Watch for these:

• Function as task, not outcome: “Enter data into system” vs. “Update customer record for billing.” The latter links to a business outcome.
• Assuming all functions are critical: Not every step needs to be mapped. Eliminate functions that add no value to KPIs.
• Mapping functions to vague goals: “Improve efficiency” is not measurable. “Reduce processing time by 20%” is.
• Ignoring cross-functional dependencies: A function in one department may rely on data from another. Map the dependency to ensure KPIs are accurate.

When I reviewed a manufacturing EPC, a function labeled “Notify warehouse” was listed as supporting “inventory accuracy.” But the notification happened after the inventory was already updated. The function didn’t affect accuracy—it was a follow-up. We removed it and redirected the KPI to the actual data entry step.

Frequently Asked Questions

How often should I re-evaluate function-KPI alignment?

At minimum, every quarter. In fast-moving environments, review after every major business change—like a new compliance rule or digital transformation rollout. Use EPC function mapping as a continuous audit, not a one-off.

Can one function map to multiple KPIs?

Yes—this is common. For example, a function like “Verify customer identity” may support both “ensure compliance” and “prevent fraud.” Clearly label each KPI to avoid confusion. Use a dual-tagging system: [compliance], [fraud prevention].

What if a function supports a goal but no KPIs exist?

Start small. Identify the business impact, then define a testable KPI. For example: “Improve customer communication” → “Reduce customer follow-up calls by 30% over six months.” Use pilot data to validate.

Should functions be mapped to departmental KPIs or company-wide KPIs?

Use company-wide KPIs as the benchmark. Departmental KPIs are useful for accountability, but EPC modeling should reflect enterprise-level goals. If a function supports a departmental target, ask: does it also help the company meet its strategic objective?

How do I handle functions that are required by law but don’t affect a KPI?

They still need to be mapped. Label them as “compliance” and assign a “compliance completion rate” KPI. For example: “File tax documentation” → “Achieve 100% filing on time.” Even if the impact is indirect, compliance is a business goal.

Can EPC function mapping be automated?

Not fully. But tools like Visual Paradigm allow you to tag functions with KPIs and generate reports. Use this to audit alignment at scale. Still, human judgment is key—automation can’t replace strategic thinking.

Final Thoughts

Mapping functions to business goals isn’t a side task. It’s the essence of EPC modeling. When you align each function with a measurable outcome, you transform a diagram into a strategic asset.

Remember: a well-mapped EPC doesn’t just show how work flows—it shows why it flows. It reveals what’s working, what’s not, and what must change.

Start with one function. Ask: what does this achieve? Then ask: how do we know it works? That’s where real EPC process efficiency begins.
