Why BPM Projects Take 18 Months

Almost every BPM project ends up taking 12 to 18 months—and that’s no coincidence. This article explains why long project durations are the structural result of an outdated paradigm and how 18 months can be reduced to four weeks.

18 months. Every time.

Ask ten companies how long their last BPM project took. You’ll hear: “Almost two years.” “We stopped after 14 months.” “Technically finished—but I don’t know if it actually works.”

This is no coincidence. It’s not a failure. And it’s not a sign of poor tools or incompetent consultants.

It is the structural result of a paradigm based on long-term commitments.

Step 1: The scope that inflates everything

Every BPM project starts with the question: “What needs to be documented?” No one knows for sure. So everyone is invited to participate. The scope expands. Before the first line has even been modeled, the project is already too big to be completed in three months.

That’s called scope creep—and it’s not an exception, but a predictable consequence: When documenting processes for people, you have to involve all stakeholders. So it takes time.

Step 2: The modeling phase that never ends

In practice: Interviews get postponed because key people don’t have time. Models get revised because “that’s not really right.” Teams can’t agree—because every team handles the process differently.

Every process sparks discussions. Discussions lead to requests for changes. Requests for changes lead to new iterations.

Multiply that by 80 processes. That comes to 18 months.

Step 3: The Change Management No One Anticipates

No one changes their behavior just because a chart says they should. So we turn to training sessions. Communication campaigns. Pilot rollouts. Feedback loops.

And here's the ironic part: even after the change management process is complete, things often still don't run the way they were supposed to. As a result, the documentation is out of date again after twelve months.

Step 4: The Counseling Model

We need to be honest about that.

A consultant who bills by the day has no financial incentive to see a project completed in six weeks. This isn’t a criticism of the industry—it’s a systemic reality.

Project duration is directly proportional to revenue. Complexity justifies allocating more resources. The incentive structures are not designed to prioritize speed.

Step 5: Integration That Is Often Underestimated

In most projects, integration is scheduled as “Phase 2.” Phase 2 begins once Phase 1 is complete. Phase 1 is never really complete. So Phase 2 never really begins.

Result: The BPM tool exists alongside the operational systems—rather than integrated with them. Employees have to switch between tools. The system is seen as an added burden, not as a help.

Why this isn't an inevitable fate

All these factors have a common cause: the paradigm.

If the goal is to document processes for people, then 18 months is both logical and unavoidable.

If the goal is different—using processes as a machine-readable database for AI systems and automation—the equation changes fundamentally:

  • No need for manual adjustment for each model
  • No change management for the organization as a whole
  • No manual modeling—automatic data capture in days, not months
  • No consulting model — SaaS instead of project work

The result: Not 18 months until the first results. Four weeks.

Not as a shortcut. But as a logical consequence of a different approach.
